  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an illumination system according to the first embodiment of the present invention.

  In FIG. 1, the terminal device 11 includes a control unit 12, an information storage unit 13, and a communication unit 14. Moreover, the illuminating device 21 is comprised by the lighting fixture 24 which has the receiving part 22, the illumination control part 23, the illumination drive parts 25a and 25b, and the light sources 26a and 26b. As the terminal device 11, an RFID (Radio Frequency Identification) (or IC tag), a mobile phone, a portable terminal device having a communication function, a watch, glasses, or the like can be employed. The information storage unit 13 stores user information for defining the type of illumination required.

  FIG. 2 is an explanatory diagram illustrating an example of user information recorded in the information storage unit 13. In the example of FIG. 2, values are recorded in the information storage unit 13 for each information item of ID, name, classification, job type, working time, age, visual acuity, and color vision. The example of FIG. 2 shows that the cashier employee of age xx years old has a visual acuity of 1.2 and normal color vision. The information stored in the information storage unit 13 may be information for controlling the light sources 26a and 26b of the lighting device 21, as will be described later, and is only single information such as age and color vision. It may also contain other information.

  For example, visual information such as visual acuity, color vision, and control function, preferences, affiliation, age, gender, address, past illness / feet / symptoms, mental status, waking up / sleeping time, etc. Time schedule ・ Monthly time schedule ・ Annual time schedule, Origin, past living place and information on the place, reaction to light, race, language, family structure, annual income, personality, current place / position, etc. Etc. can be adopted.

  The communication unit 14 can communicate with other communication units via a predetermined transmission path, for example, a wireless transmission path using radio waves. The control unit 12 can control the communication unit 14 to transmit / receive information to / from the reception unit capable of communicating with the communication unit 14 and transmit information read from the information storage unit 13 to the reception unit. The terminal device 11 can be provided on a person's portable object such as a name plate, a mobile phone, a watch, and glasses.

  The receiving unit 22 of the lighting device 21 can communicate with the communication unit 14 of the terminal device 11. The reception unit 22 supplies information transmitted from the terminal device 11 to the illumination control unit 23. The lighting control unit 23 controls the lighting fixture 24 based on the received information.

  In the example of FIG. 1, the lighting fixture 24 has shown the example which has two illumination drive parts and a light source. The light source 26a and the light source 26b can emit different types of illumination light, that is, light having different illumination attributes such as brightness, color, and wavelength. The illumination driver 25a causes the light source 26a to emit light, and the illumination driver 25b causes the light source 26b to emit light.

  The illumination control unit 23 controls the illumination driving units 25a and 25b based on the information received from the terminal device 11. For example, the illumination control unit 23 can control the illumination driving units 25 a and 25 b so that only one of the light sources 26 a and 26 b emits light according to information from the terminal device 11. Moreover, the illumination control part 23 can also control the illumination drive parts 25a and 25b so that the light sources 26a and 26b emit light only when information is received from the terminal device 11.

  By carrying the terminal device 11 by a person and transmitting the user information of the portable person to the lighting device 21, it is possible to obtain a personal lighting environment suitable for the portable person or effective.

  Further, the user information transmitted from the terminal device 11 may be presence information that simply indicates presence, and in this case, at least one of the light sources 26a or 26b is set to be turned on when the presence information is received. You just have to.

  Further, if at least one of the light source 26a and the light source 26b is turned on only when the portable person approaches and the illumination control unit 23 receives the presence information from the terminal device 11, the portable person can move to a predetermined area. Lights as long as you are inside.

  That is, according to the lighting system of the present embodiment, the lighting is not accidentally turned off during the work, and the light is turned on when the user is present in the predetermined area, and is turned off when the user is absent. Can be performed reliably.

  Next, the first embodiment configured as described above will be described with reference to FIGS.

  FIG. 3 shows an example applied to the lighting of a late-night business store such as a convenience store.

  In the late-night business store 31, the lighting device 21 is disposed on the ceiling surface 32, and the lighting fixture 24 having the light sources 26a and 26b is attached.

  For store workers, it is preferable to irradiate light having an effect of preventing drowsiness or improving the arousal level because work at night is easy to feel drowsiness.

  On the other hand, if a user who visits a store at night is exposed to such light, good sleep may be hindered after returning home.

  That is, in a late-night business store, preferable lighting environments are different for workers who want to prevent drowsiness and maintain a high arousal level, and users who normally want to sleep at night.

  Therefore, as shown in FIG. 3A, when the worker 41 is illuminated, the light source 26b can emit light having an effect of preventing drowsiness or improving the arousal level. Further, as shown in FIG. 3B, when the consumer 34 is illuminated, the light source 26a can irradiate light with little influence on the rhythm of the consumer 34.

  Human sleep is affected by the secretion of melatonin called sleep hormone. It has also been known that melatonin secretion is suppressed by a specific wavelength. FIG. 4 is a graph showing the relationship between the degree of suppression of melatonin secretion and the wavelength. 4A and 4B show the relative value or logarithmic value indicating the wavelength on the horizontal axis and the melatonin suppression degree on the vertical axis.

  As shown in FIGS. 4A and 4B, the melatonin suppression degree has a maximum value at a wavelength of about 464 nm and has an effective value at a wavelength of about 560 nm or less. However, when the wavelength is 400 nm or less, the energy of light becomes strong, which may adversely affect the eyeball. Therefore, when irradiating light containing a wavelength component of about 400 to 560 nm, for example, monochromatic light having a peak wavelength within 400 to 560 nm or polychromatic light having a wavelength of 400 to 560 nm, melatonin secretion without adversely affecting the eyeball Can be suppressed. Moreover, the full width at half maximum of the melatonin suppression degree is about 100 nm, and when it is irradiated with light containing a wavelength component of 410 to 510 nm, melatonin secretion can be effectively suppressed.

  On the other hand, it was confirmed by experiments that monochromatic light having a peak wavelength in the range of 400 to 560 nm or light having a wavelength of 400 to 560 nm has an effect of improving arousal level. In the case of monochromatic light having a peak wavelength in the range of 400 to 560 nm, it has been confirmed that this effect is effective at about 1 lux when the intensity of light reaching the eyeball is expressed by, for example, illuminance.

  At present, the correlation between the effect of improving arousal level by monochromatic light having a peak wavelength in the range of 400 to 560 nm or the light having a wavelength of 400 to 560 nm and the effect of preventing sleepiness by suppressing the secretion of melatonin is unknown. From the above two viewpoints, it is considered that drowsiness can be prevented by the light having a spectral distribution having a wavelength of 400 to 560 nm, and the arousal level can be maintained high.

  Therefore, in the present embodiment, the light source 26b is configured to be able to irradiate monochromatic light having a peak wavelength in the range of 400 to 560 nm, and can simultaneously improve the arousal level and suppress melatonin secretion. As such a light source, for example, a blue LED or a blue EL that emits monochromatic light having a peak wavelength of 400 to 560 nm, preferably 410 to 510 nm can be employed. Moreover, the light aiming at improving the arousal level and the light aiming at suppressing melatonin secretion may be configured by different light sources, and different lighting control may be performed. Furthermore, it is preferable that the light source 26b irradiates light of a light bulb color or white simultaneously with these lights in order to ensure the workability of the worker 41 in the store.

  FIG. 5 is a graph showing daily changes in body temperature and agility in the internal rhythm with respect to secretion of two hormones, cortisol and melatonin, with time on the horizontal axis.

  It can be seen from FIG. 5 that melatonin secretion occurs mainly at night. For this reason, when it is necessary to work for a long time at midnight, it is thought that suppressing melatonin secretion is effective in preventing drowsiness.

  On the other hand, when the user 34 is exposed to monochromatic light having a peak wavelength in the range of 400 to 560 nm or light including a wavelength of 400 to 560 nm at night, the sleep hormone melatonin is suppressed and good sleep is achieved. May be inhibited.

  Therefore, the light source 26a is composed of light that does not include a wavelength of 400 to 560 nm and has an effect of suppressing melatonin secretion and an effect of improving arousal level. For example, light bulb color light or white light not including a wavelength of 400 to 560 nm can be used.

  FIG. 6 is a flowchart for explaining the control of the illumination control unit 23.

  The lighting control unit 23 of the lighting device 21 controls the lighting fixture 24 based on the information captured via the receiving unit 22. For example, when the captured information indicates that the employee is an employee of the late-night business store 31, the illumination control unit 23 controls the illumination driving units 25a and 25b so that only the light source 26b is turned on. The illumination control unit 23 turns on only the light source 26a when information is not captured via the reception unit 22 or when it is determined that the information is not an employee based on the captured information.

  Now, it is assumed that a specific worker 41 in the late-night business store 31 carries the terminal device 11 in which the information storage unit 13 stores the information of FIG. It is assumed that the worker 41 moves to the vicinity of the work table 42 for accounting work or the like as shown in FIG. When the control unit 12 of the terminal device 11 controls the communication unit 14 and detects that the reception unit 22 capable of communicating with the communication unit 14 exists in the communication area of the communication unit 14, the information storage unit 13. The information is read out from the communication unit 14, and the information is transmitted from the communication unit 14 to the reception unit 22.

  The information from the communication unit 14 is supplied to the receiving unit 22 by the worker 41 moving to the vicinity of the work table 42. In step S <b> 1 of FIG. 6, the illumination control unit 23 acquires information from the reception unit 22. In step S2, the lighting control unit 23 determines whether the person holding the terminal device 11 is a store employee based on the information. In this case, since it is a store employee, the process proceeds to step S4, and the illumination driving units 25a and 25b are controlled so as to illuminate with light suitable for the employee, for example, light having a melatonin suppressing effect. To do. Thus, in this case, only the light source 26b is turned on, and the vicinity of the work table 42 is illuminated so as to raise the employee's arousal level.

  As described above, in the present embodiment, lighting is controlled in accordance with information from the terminal device 11, and by registering personal information in the terminal device 11, a lighting environment suitable for the individual can be obtained. Can do.

  In the above description, the user 34 who uses the store is described as not holding the terminal device 11, but it is also conceivable that not only the store employee but also the user 34 holds the terminal device 11. . In this case, priority may be provided for the information. For example, the priority of the user 34 is set higher than that of the worker 41. Then, for example, when the worker 41 is working near the display shelf 33, when the user 34 approaches the display shelf 33, the illumination control unit 23 switches the lighting state of the light source 26b to the lighting state of the light source 26a. It is also possible.

  Moreover, in the said embodiment, although the example which the illumination control part 23 switches illumination based on the information from the terminal device 11 was demonstrated, illumination on / off control is also carried out by the presence or absence of the information from the terminal device 11. Is possible. That is, when the communication unit 14 of the terminal device 11 reaches an area where the communication unit 14 of the terminal device 11 can communicate with the receiving unit 22 of the lighting device 21, the lighting control unit 23 turns on the lighting, and the communication unit 14 of the terminal device 11 turns on the receiving unit 22 of the lighting device 21. The illumination control unit 23 turns off the illumination when it is located in an area where communication with the device is impossible. In this case, the illumination can be turned on even when the person carrying the terminal device 11 is stopped in an area where communication is possible.

  Further, the light source 26a and the light source 26b may be turned on simultaneously. For example, the light source 26a always illuminates the store, and when the worker 41 holding the terminal device 11 approaches the lighting device 21 and the communication unit 14 and the receiving unit 22 can communicate with each other, the light source unit 26b is also turned on. Let

  Next, as a second embodiment, an example in which illumination is controlled according to age will be described with reference to FIGS. FIG. 7 is a flowchart for explaining the control of the illumination control unit 23 in this example. FIG. 8 is an explanatory diagram for explaining the relationship between age and appearance.

  A person can see things through the path of cornea → lens → vitreous → retina → cerebrum. Of these, the lens becomes clouded with age. When the lens is white and cloudy, the light that enters the eye scatters within the eye, making it difficult to see. If you perform visual work when it is difficult to see things, your eyes will be tired easily, and work efficiency and comfort will be significantly impaired. Therefore, it is desirable to reduce the light scattered in the eye as much as possible as the age increases.

  For example, as the light source 26a in FIG. 1, a light source that enables overall illumination including the object and its surroundings is used, and as the light source 26b, a light source that irradiates light on the object in a spot manner is used. For example, it is assumed that a person who is young carries a terminal device 11 storing information related to his / her age. For example, it is assumed that this person moves to the vicinity of the lighting device 21 and communication between the communication unit 14 and the reception unit 22 becomes possible. Then, the illumination control unit 23 acquires information from the reception unit 22 in step S1 of FIG. 7, and determines the age of the person holding the terminal device 11 based on the acquired information in step S12. In this case, since the target person is a young person, the process proceeds to step S13, the light source 26a is turned on, and the entire area of the object is illuminated.

  The upper part of FIG. 8A shows an example of illumination (hereinafter referred to as environmental illumination) performed on the object and the entire area around it. The lower part of FIG. 8A explains the light that enters the eyes during environmental illumination. In FIG. 8, a white arrow indicates reflected light from the object to be viewed, and a solid arrow indicates reflected light from the periphery of the object to be viewed. The width of the arrow indicates the amount of light. As shown in FIG. 8A, most of the reflected light from the periphery of the visual target is incident on the eye under environmental illumination.

  Even under such environmental lighting, there is no particular problem for young people. However, for an elderly person, as described above, due to the white turbidity of the crystalline lens, the scattered light in the eye increases due to the reflected light from the periphery of the object under environmental illumination, and it becomes difficult to see things. End up. When working in such a state that it is difficult to see, the eyes are tired and work efficiency and comfort are impaired.

  Therefore, in the present embodiment, illumination using spot light (hereinafter referred to as target illumination) is performed for elderly people. For example, it is assumed that an elderly person 65 years or older carries the terminal device 11 storing information related to his / her age. When the person moves to the vicinity of the lighting device 21 and communication between the communication unit 14 and the receiving unit 22 becomes possible, the lighting control unit 23 acquires information from the receiving unit 22 in step S1 of FIG. In S12, the age of the person holding the terminal device 11 is determined. In this case, since the target person is an older person 65 years or older, the process proceeds to step S14, and the light source 26b is turned on. The light source 26b irradiates the object spotwise.

  The upper part of FIG. 8B shows target illumination for irradiating the target with spot light in this way. The lower part of FIG. 8B explains the light that enters the eyes during target illumination. As shown in FIG. 8B, under the target illumination, the reflected light from the periphery of the visual target hardly enters the eyes. That is, in this case, the scattered light in the eye is small and the object is easy to see. Therefore, even an elderly person can easily see the object.

  As described above, in the examples of FIGS. 7 and 8, the illumination is automatically switched according to the age, and an environment in which the object can be easily seen even by an elderly person can be obtained.

  As a third embodiment, another example of performing illumination control according to age will be described.

  The spectral transmittance of the human eyeball tends to decrease with age. FIG. 9 is a graph showing changes in spectral transmittance according to age, with the horizontal axis representing wavelength and the vertical axis representing spectral transmittance. As shown in FIG. 9, as the age increases, the spectral transmittance decreases in the entire wavelength range. In particular, as the age increases, it becomes difficult to distinguish blue light in the short wavelength region, and the ability to identify color differences also decreases.

  Therefore, for example, it is conceivable that the light source 26b generates light containing more components in the short wavelength region than the light from the light source 26a, or light excellent in color rendering. The light control unit 23 turns on the light source 26a for younger people and turns on the light source 26b for older people. Thereby, even an elderly person can recognize the color of the material faithfully.

  As a fourth embodiment, an example in which illumination control is performed according to visual individual differences will be described. For example, by using information on the type of abnormal color vision, the attributes of the light that illuminates the visual object between the person with normal color vision and the color vision abnormal person can be changed so that the visual object can be visually recognized even by the color blind person. It is possible to make it possible to see even a visual object that cannot be seen with normal lighting.

  In general, it is difficult for a person with low vision or an elderly person to recognize an object when the illumination is low. For this reason, you may change the illumination intensity of illumination according to the visual change accompanying visual acuity or age.

  As a fifth embodiment, a case will be described in which lighting control is performed according to a disease such as a sleep disorder or a mental state.

  For example, for a person with a sleep disorder whose sleep / wake rhythm is different from a general 24-hour rhythm, by acquiring information on the sleep / wake rhythm, bright light is appropriately given to correct the rhythm. be able to.

  In the above embodiment, an example of controlling illumination light based on information from the terminal device 11 has been described. However, other environmental factors such as air conditioning, sound, and building materials may be controlled simultaneously. Good. Moreover, although the example which employ | adopted 2 systems of illumination drive parts and light sources was demonstrated in FIG. 1, you may employ | adopt 3 or more systems of illumination drive parts and light sources. In addition, if one type of illumination driving unit and light source can irradiate a plurality of types of light, one type of illumination driving unit and light source may be employed. Further, the output may be changed only by one system.

  FIG. 10 is a block diagram showing a fifth embodiment of the present invention. In FIG. 10, the same components as those in FIG.

  In each of the above embodiments, when a plurality of lighting devices are arranged at positions relatively close to each other, any lighting device is effective for a person carrying the terminal device. It may be difficult to determine whether to provide a proper lighting environment. Therefore, in the present embodiment, an example is shown in which an illumination device that provides illumination is specified according to the reception strength of communication between the terminal device and the illumination device.

  In FIG. 10, the communication unit 62 of the lighting device 61 can communicate with the terminal device 51 in the same manner as the reception unit 22 of FIG. 1. The storage unit 23 a holds unique ID information for each lighting device 61. The illumination control unit 23 can read this ID information from the storage unit 23 a and wirelessly transmit it from the communication unit 62. Further, the communication unit 62 captures only the transmission signal to which the ID information of the own device is added among the transmission signals of the terminal device 11 and supplies the information included in the captured transmission signal to the illumination control unit 23. It has become.

  In FIG. 10, the communication unit 54 of the terminal device 51 can communicate with a plurality of lighting devices 61 in the same manner as the communication unit 14 of FIG. 1, and can output information on reception intensity to the control unit 52. It can be done. The control unit 52 can perform the same control as that of the control unit 12 in FIG. 1 and totals information on the received intensity from the communication unit 54. As described above, the transmission signal of each lighting device 61 includes ID information that individually identifies each lighting device 61, and the control unit 52 has a lighting device 61 (hereinafter referred to as a communication destination) having the highest reception intensity. , The lighting device 61 having the maximum reception intensity). In order to request the illumination control to the illumination device 61 with the maximum reception intensity, the control unit 52 can designate the illumination device 61 with the maximum reception intensity as a destination and transmit the information in the information storage unit 13. It has become.

  Other configurations are the same as those of the first embodiment.

  In the embodiment configured as described above, a plurality of lighting devices 61 are disposed on, for example, an indoor ceiling. Each lighting device 61 can communicate with the terminal device 51 in a predetermined communicable area near the own device. The communication part 62 of each illuminating device 61 is transmitting the transmission signal containing ID information of an own machine at a predetermined time interval.

  On the other hand, the terminal device 51 receives a transmission signal from the communication unit 62. It is assumed that a person carrying the terminal device 51 moves in the room. For example, the terminal device 51 may be located in the communicable area of the plurality of lighting devices 61. In this case, the terminal device 51 receives transmission signals from the communication units 62 of the plurality of lighting devices 61 in the communicable area.

  The communication unit 54 of the terminal device 51 outputs ID information and reception intensity information included in the received signal to the control unit 52 for each lighting device 61. The control unit 52 compares the reception strengths of the signals received by the communication unit 54 and acquires ID information included in the transmission signal that provides the strongest reception strength.

  The control unit 52 recognizes the illumination device 61 specified by the ID information included in the transmission signal from which the maximum reception intensity is obtained as the illumination device 61 having the maximum reception intensity. The control unit 52 reads the information stored in the information storage unit 13, designates the illuminating device 61 with the maximum reception intensity as the destination, and transmits the information via the communication unit 54.

  It is conceivable that the transmission signal from the communication unit 54 reaches a plurality of lighting devices 61. The transmission signal from the communication unit 54 includes ID information, and only the communication unit 62 having this ID information receives and takes in the transmission signal from the communication unit 54. Thus, the user information stored in the terminal device 51 is captured in the lighting device 61 having the maximum reception intensity.

  The lighting device 61 having the maximum reception intensity is considered to be the lighting device closest to the terminal device 51. Thereby, illumination control of the illumination device 61 at the position closest to the person carrying the terminal device 51 is controlled based on the information in the terminal device 51.

  As described above, in the present embodiment, the terminal device obtains the reception strength of radio waves from a plurality of lighting devices, and transmits user information using the lighting device that can obtain the maximum reception strength as the transmission destination. It is possible to automatically determine and control the illumination device at the position closest to.

  FIG. 11 is a block diagram showing a sixth embodiment of the present invention.

  In the fifth embodiment, a lighting device at a close position is determined on the terminal device side. On the other hand, this Embodiment determines the illuminating device of the position close | similar to a terminal device with another apparatus.

  In FIG. 11, a terminal device 11 is the same terminal device as in the first embodiment, and has a user information transmission function. The illumination device 65 has the same configuration as the illumination device 21 of FIG. Further, the reception unit (see FIG. 1) of the illumination device 65 can output information on the reception intensity. In addition, the illumination device 65 can send and receive information to and from the control device 66 by a communication unit (not shown), and can output information on the reception intensity of the signal received by the reception unit 22 to the control device 66. Yes. Furthermore, the lighting device 65 determines whether to control the lighting fixture 24 based on the user information received by the receiving unit 22 according to an instruction from the control device 66.

  The control device 66 is given information on the reception intensity from each lighting device 65. The control device 66 aggregates information on the received intensity from each lighting device 65. The control device 66 identifies the lighting device 65 having the highest reception intensity of the transmission signal from the terminal device 51 (hereinafter referred to as the lighting device 65 having the maximum reception intensity). The control device 66 instructs the illumination device 65 having the maximum reception intensity to perform illumination control based on the user information.

  In the embodiment configured as described above, the plurality of lighting devices 65 output information on the reception intensity of the user information received from the terminal device 11 to the control device 66. The control device 66 instructs the illumination device 65 that has received the user information with the highest reception intensity to perform illumination control based on the user information. Thereby, illumination control of the illumination device 65 at the position closest to the person carrying the terminal device 11 is controlled based on the information in the terminal device 11.

  In the fifth and sixth embodiments, only one illumination device is controlled for illumination, but a plurality of illumination devices may be controlled. For example, the terminal device may transmit the user information with the lighting device that is the transmission source of the two transmission signals having the highest reception strengths as the destination. Further, the terminal device may transmit the user information with the lighting device that is the transmission source of the transmission signal having a reception intensity equal to or higher than a predetermined threshold as the destination.

  Furthermore, in the case of controlling a plurality of lighting devices, each can be controlled according to the reception intensity. For example, the degree of control may be changed according to the reception intensity ratio, or the position of the terminal device is specified from the reception intensity ratio, and each lighting apparatus is controlled so that a desired lighting state is obtained at that position. May be. By specifying the position of the terminal device, for example, when a desired lighting state cannot be obtained with only one lighting device, adjacent lighting devices may be controlled.

  FIG. 12 is a flowchart showing a seventh embodiment of the present invention. The hardware configuration of the present embodiment is the same as that shown in FIG. 10, and only the control in the illumination control unit 23 is different.

  In each of the embodiments described above, illumination control is performed for the illumination device that communicates with the terminal device. In this embodiment, the lighting device maintains lighting control for the previous terminal device until communication with another terminal device is performed after communication with the terminal device is interrupted.

  The illumination control unit 23 (see FIG. 10) in the present embodiment performs illumination control based on the received user information, as in the fifth embodiment. Further, even when the user information is not received, the lighting control unit 23 is configured to maintain the previous lighting control until new user information is input next time.

  In step S <b> 21 of FIG. 12, the first user holding the terminal device approaches the lighting device 61 and user information is taken into the lighting device 61. The illumination control unit 23 of the illumination device 61 performs illumination control in the setting state of the first user (step S22).

  In step S23, the illumination control unit 23 determines whether user information of the second user has been received. In step S23, it is assumed that the first user has moved and no user information is received from the terminal device.

  Here, it is assumed that the lighting device 61 does not receive user information from the terminal device held by the second user. In this case, the illumination control unit 23 maintains the setting state of the first user in step S24.

  And when the 2nd user approaches the said illuminating device 61 and the user information from the terminal device which a 2nd user hold | maintains in the illuminating device 61, the illuminating device 61 is 2nd in step S25. Lighting control is performed in the user setting state.

  In step S23, when the user information of the second user is received while the user information of the first user is received, the priority of the user information of the first user and the user information of the second user is determined. However, the lighting control may be performed in the setting state with the higher priority.

  As described above, in the present embodiment, even if user information from the terminal device is not received, the illumination control up to that point is maintained, and it is possible to prevent the illumination from being turned off. .

  In the above embodiment, the lighting control is maintained until other user information is received, but after a predetermined time after the user information is not received, the lighting control is automatically returned to the initial value, The lighting may be turned off. Furthermore, when grouping is performed in which control is performed simultaneously on a plurality of lighting devices, if user information is not received by all the lighting devices in the group, the lighting is automatically turned off. You may make it do.

  FIG. 13 is a flowchart showing the eighth embodiment of the present invention. The hardware configuration of the present embodiment is the same as that shown in FIG. 10, and only the control in the illumination control unit 23 is different.

  The user information includes information on subjectivity such as preference as well as information on visual acuity, color vision, age, gender, etc., and in each of the above embodiments, an example of individually controlling lighting based on these user information explained. However, for general lighting for an unspecified number of people, it may be better not to perform lighting control based on the subjectivity of one individual. This embodiment considers such a case.

  The illumination control unit 23 (see FIG. 10) performs illumination control based on the received user information, as in the fifth embodiment. Furthermore, the lighting control unit 23 in the present embodiment does not perform lighting control based on user information regarding subjectivity for general lighting for the unspecified majority, but for personal lighting such as task lighting or general lighting for the specified number. Only lighting control based on user information regarding subjectivity is performed.

  In step S31 of FIG. 13, when the lighting control unit 23 receives the user information, in step S32, it detects subjective information such as preferences from the user information. For user information other than subjective information, the illumination control unit 23 performs illumination control based on the user information in step S34.

  On the other hand, when subjective information is included in the user information, the illumination control unit 23 determines whether or not the illumination to be controlled is illumination for an unspecified number of people such as general illumination in step S33. In the case of unspecified majority illumination, the illumination control unit 23 ends the process without performing illumination control. For non-unspecified majority lighting, for example, personal lighting such as task lighting, or general lighting such as for specific decimal or specific majority having a common preference, the lighting control unit 23 performs lighting control based on user information. (Step S34).

  As described above, in the present embodiment, when the user information is subjective information, it is possible to prevent lighting for an unspecified number of people from being controlled by the subjective information. As a result, it is possible to prevent the general illumination from being controlled by specific personal preferences.

  FIG. 14 is a flowchart showing the ninth embodiment of the present invention. The hardware configuration of the present embodiment is the same as that shown in FIG. 10, and only the control in the illumination control unit 23 is different.

  By the way, in the above-described fourth embodiment, it has been described that even a color blind person can recognize a color by illumination light. This embodiment is applied to the case where two or more people with different color vision types exist in the illumination area of the same lighting device.

  For example, a color blind person and a color blind person, or two or more color blind persons of different color vision types may be located in close proximity. FIG. 14 shows the control in this case.

  In step S41 of FIG. 14, when the lighting device receives the user information, the lighting device determines the color vision type included in the user information (step S42). The illumination device performs illumination control according to the color vision type. According to the 2006 Annual Conference of the Illuminating Society of Japan “Proposal for Color Barrier-Free Lighting”, the deuteranopia (two-color type second anomaly), which is said to have the largest number of color vision abnormalities, is on the confusion line It was theoretically shown that two colors can be separated from the confused color line by illumination and made distinguishable. The lighting device controls the color or wavelength of the illumination according to the color vision type included in the user information, thereby enabling the color vision type person to identify the color (step S44).

  Here, it is assumed that a person with a different color vision type moves into an illumination area of a lighting device that performs illumination for a person with a predetermined color vision type. In step S42, the lighting device determines the color vision type of the person who has moved later, and the process proceeds from step S43 to step S45. In step S <b> 45, the lighting device determines whether or not effective lighting for different color vision types included in the user information has a relationship of opposite colors. If it is not the relationship of the opposite color, the lighting device shifts the process to step S46, and irradiates the already performed illumination with an illumination effective for the color vision type of the person who has moved later.

  Thereby, in the illumination area of the illumination device, effective illumination is performed for each person of different color vision types, and each color vision type person can identify the color.

  In addition, when the effective illuminations for the different color vision types are in the relationship of opposite colors, it may not be possible to identify the colors for both color vision types when these lights are added. The current lighting control is maintained without adding effective lighting to the color vision type of the person who has moved later.

  In addition, when a person moves out of the lighting area of the lighting device, the lighting device turns off the lighting effective for the color vision type of the moved person and is effective only for the person remaining in the lighting area. Illuminate. In addition, when the illuminations effective for people of different color vision types are in the relationship of opposite colors, for the effective illumination for the person who has moved afterwards, the illumination device will “currently irradiate the terminal device of the user” The information “impossible” is sent, and after the user of the cause leaves, the information “currently available” is sent to irradiate the necessary light.

  As described above, in this embodiment, by using the color vision type information of the color blind person, the attribute of the light that illuminates the visual object is changed between the person with normal color vision and the person with color blindness. It is possible for a person to easily see a visual object and to see a visual object that cannot be seen with normal lighting. Moreover, even if the color vision abnormality person has a different color vision type, it is possible to facilitate visual recognition of the visual target object by adding illumination with effective light.

  FIG. 15 is a flowchart showing the tenth embodiment of the present invention. The hardware configuration of the present embodiment is the same as that shown in FIG. 10, and only the control in the illumination control unit 23 is different.

  In the example applied to the lighting of the midnight business store in FIG. 3 described above, the priority between the store worker and the store user has been described. This embodiment shows an example in which the priorities of store workers are further defined.

  As a store worker, in addition to a day shift worker (including a normal night worker) who is a worker who does not work late at night, a late night worker and the like can be considered. For late-night workers, it is preferable to irradiate light having an effect of preventing drowsiness or improving the degree of arousal because late-night work tends to cause drowsiness. On the other hand, if a day shift worker or the like is exposed to such light, good sleep may be hindered after returning home. Therefore, in this embodiment, the lighting environment in the store is changed according to the type of worker.

  In the store, there are a common area for customers and workers and an area dedicated to workers. For example, the common area may be a sales floor, a toilet, etc., and the worker-dedicated area may be a cash register, an office, or the like. In the present embodiment, the lighting environment is controlled not only by distinguishing customers, day shift workers, and late night workers but also by distinguishing areas.

  In step S51 of FIG. 15, the illumination control unit 23 (see FIG. 10) acquires user information. The lighting control unit 23 determines whether the lighting fixture 24 to be controlled illuminates the worker-dedicated area or the common area. When the lighting fixture 24 to be controlled illuminates the worker-dedicated area, the lighting control unit 23 shifts the processing from step S52 to step S55, and determines whether the user information is a day shift worker or a late night worker. Is determined. And in the case of a day shift worker, it transfers to step S54 and performs illumination control by normal illumination. On the other hand, in the case of a late-night worker in step S55, the process proceeds to step S56 and illumination is performed with light having a melatonin suppressing effect.

  If the lighting fixture 24 to be controlled illuminates the common area, the lighting control unit 23 determines whether there are customers or day shift workers (including night workers) in the target area in the next step S53. Determine whether or not. When a customer or a day shift worker exists, the illumination control unit 23 performs illumination control with normal illumination in step S54. Thereby, a customer, a day shift worker, etc. are not irradiated with the light which has a melatonin suppression effect, and it is prevented that these people are adversely affected. On the other hand, when only the late-night worker is present in the target area, the illumination control unit 23 proceeds to step S56 and performs illumination with light having a melatonin suppressing effect.

  Thereby, for example, even when a customer enters the store, the common area for the customer and the worker gives priority to the customer and performs illumination control with normal lighting. In addition, when a day shift worker and a late night worker enter the common area at the same time, priority is given to a worker who does not work late at night, and lighting control is performed using normal lighting.

  As described above, in this embodiment, a customer or a day shift worker and a late night shift worker are present in the same lighting area, and a person who wants to improve arousal level and a person who wants to improve are distinguished from each other. Separately, the lighting can be controlled.

  FIG. 16 is a flowchart showing an eleventh embodiment of the present invention. The hardware configuration of the present embodiment is the same as that shown in FIG. 10, and only the control in the illumination control unit 23 is different.

  In the second embodiment described above, an example of switching to target illumination according to age is shown, and in the third embodiment, an example of switching wavelength and color rendering properties according to age is shown. This embodiment shows an example in which the illuminance is switched according to the age.

  The illumination control unit 23 in the present embodiment controls to switch the illuminance according to the age. In this case, if a plurality of illuminances are set in accordance with the age range, the illuminances may be frequently switched when dealing with an unspecified number of people. Therefore, in this embodiment, only two types of illuminance to be set are set, and the illuminance is switched between under 60 years old and over 60 years old.

  According to a report from the Japan Society for Lighting Science “Basic Study on Lighting Visual Environment Considering the Visual Characteristics of the Elderly”, the upper limit set in JIS Z9110-1979 is sufficient for the required illuminance in the housing of the elderly . As general illumination becomes a higher illuminance environment, it causes an increase in scattered light in the eye of the elderly, so it is necessary to determine the upper limit of illuminance with some value. Therefore, in the present embodiment, the upper limit value in the range defined by JIS Z9110-1979 is adopted as the upper limit value of illuminance. The branching age of the illuminance value to be set is 60 years since the decrease in the spectral transmittance of the lens is dramatically reduced from 60 to 70 years old when viewed by age.

  In step S61 of FIG. 16, the illumination control unit 23 acquires user information. The lighting control unit 23 determines whether or not a person 60 years or older is included in the irradiation area of the target lighting fixture 24 from the acquired user information. If not included, that is, for a person under the age of 60, the illumination control unit 23 performs illumination control so that the illuminance is the lower limit of the illuminance range defined in JIS Z9110-1979 (step S63).

  On the other hand, when there is a person 60 years or older, the illumination control unit 23 performs illumination control so that the illuminance is the upper limit value of the illuminance range defined in JIS Z9110-1979 (step S64). As described above, when there are persons of different ages, for example, when persons of 55 years old and 68 years old have entered the irradiation area, the control is performed according to the elderly person.

  Thus, in this Embodiment, it has the effect that it can set to the illumination intensity according to age.

  The upper limit value and the lower limit value of the illuminance range can be set as appropriate. In addition to those defined in JIS Z9110-1979, a predetermined upper limit value and a predetermined lower limit value may be set.

  Moreover, although this Embodiment showed the example applied to the general lighting environment generally used, it is applicable also to the area control in which the illumination control for every area which irradiates light is possible.

  Although the seventh to eleventh embodiments described above are applied to the fifth embodiment, it is obvious that the seventh to eleventh embodiments can be similarly applied to the first embodiment.
