It is a block diagram which illustrates the composition of the illuminating device concerning the embodiment of the present invention. It is a circuit diagram equivalent to the structure of the illuminating device shown in FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same element and the overlapping description is abbreviate | omitted. Further, the drawings referred to in the following description only schematically show the shape, size, and positional relationship so that the contents of the present invention can be understood. That is, the present invention is not limited only to the shape, size, and positional relationship illustrated in each drawing.

  FIG. 1 is a schematic view illustrating the internal configuration of a lighting device according to an embodiment of the invention. FIG. 2 is a schematic view illustrating the appearance of the illumination device. FIG. 3 is a block diagram illustrating the configuration of the illumination device. As shown in FIGS. 1 to 3, the lighting device 1 according to the present embodiment includes a housing 10, a human sensor module 21 housed in the housing 10, a light source unit 22, a sound module 23, a speaker 24, and And an electronic component such as a power supply means 25 for supplying power to these components. In addition, a switch (for example, a button switch) 26 for switching an audio signal output from the audio module 23 is attached to the housing 10.

  The housing 10 includes a dome-shaped cover 11 and a support 12 that is integrated with the cover 11 and forms a space therein. Various electronic components described above are accommodated in a space formed by the cover 11 and the support 12. An opening 11a is formed at the tip of the cover 11, and a part of the human sensor module 21 is exposed from the opening 11a (see FIG. 2). A detailed configuration of the housing 10 will be described later.

  The human sensor module 21 detects the presence of a living body such as a person and outputs a detection signal. Specifically, the human sensor module 21 includes, for example, an infrared sensor that detects infrared rays emitted from a living body, and detects a change in temperature distribution within a predetermined area around the lighting device 1. The human sensor module 21 has a timer function. When the presence of a living body is detected, the detection signal is turned on and this state is maintained for a predetermined time (for example, 60 seconds). Thereafter, the movement of the living body is detected or newly If the presence of the living body is not detected, the detection signal is turned off. This timer function is realized by, for example, a function of a MOS (Metal Oxide Semiconductor) constituting the infrared sensor.

  The circuit board 201 on which the human sensor module 21 is mounted is held above a lighting board 203 to be described later by a support column 202. Thereby, when the cover 11 is put on, the lens part of the human sensor module 21 (the part that collects infrared rays) is exposed from the opening 11 a provided in the cover 11 and passes through the vicinity of the lighting device 1. The presence of people and the like can be detected with higher sensitivity.

  The light source unit 22 includes, for example, at least one LED element, and generates light according to the detection signal output from the human sensor module 21. That is, the light source unit 22 is turned on while the detection signal is on, and is turned off when the detection signal is turned off. In the present embodiment, the light source unit 22 includes a plurality of LED elements 221 disposed on the illumination board 203 and a drive circuit that drives the LED elements 221. The lighting substrate 203 is preferably formed of a metal such as aluminum in order to improve heat dissipation.

  The audio module 23 includes a memory that stores audio data, an audio signal output unit that outputs an audio signal (electric signal) based on the audio data stored in the memory, and an amplifier that amplifies the audio signal. An audio signal is output according to the detection signal output from the sense sensor module 21. Specifically, the audio module 23 outputs a series of preset audio signals triggered by the detection signal being turned on.

  The storage capacity of the memory is at least capable of storing voice data for generating a short (single sentence) message in multiple languages such as Japanese, English, Chinese, Korean, etc. good. Further, a plurality of types of audio data may be stored in the memory, and the type of the audio signal output from the audio module 23 (that is, the type of audio emitted from the lighting device 1) may be appropriately switched according to a predetermined operation. For example, voice data for generating multiple messages in multiple languages, such as “Thank you,” “Thank you,” “No smoking,” etc. may be stored in memory. Voice data such as sirens and warning sounds may be stored in the memory. In this embodiment, every time the switch 26 is pressed, the contents of the message, the siren, and the like are sequentially switched.

  The voice data stored in the memory may be recorded by the user himself or may be synthesized voice. Moreover, it is good also as changing the kind of the audio | voice signal output from the audio | voice module 23 by using a portable storage medium (for example, micro SD card) as memory and replacing a storage medium. Alternatively, the voice module 23 may be provided with a communication function so that voice data stored in the memory can be rewritten by remote operation using a smartphone or the like.

  The speaker 24 generates sound based on the sound signal output from the sound module 23. As the speaker 24, in order to suppress deterioration in sound quality due to temperature rise in the housing 10, a cone type speaker in which the vibration part is formed of paper or metal is used rather than a so-called rubber speaker in which the vibration part is formed of rubber. It is preferable.

  The specs of the speaker 24 may be appropriately selected according to the size and use of the lighting device 1. For example, when the lighting device 1 is attached to the ceiling of a general house and a person passing underneath hears sound, a speaker with an output of about 1 W may be used.

  Here, in order to increase the volume of the sound generated from the lighting device 1, the loudspeaker 24 with a large output may be used. Operation may become unstable. Therefore, it is preferable to take one or more countermeasures against heat. Specifically, a heat-resistant module that can withstand heat of, for example, about 80 ° C. is used as the voice module 23 to suppress heat conduction to the voice module 23 by sticking a tape of heat insulating material around the voice module 23. Adopting measures, such as arranging the audio module 23 and the speaker 24 as far apart as possible, can be mentioned.

  The power supply means 25 includes a constant current power source 251 that supplies power to a system including the human sensor module 21 and the light source unit 22 (hereinafter also referred to as sensor system), a system including the audio module 23 and the speaker 24 (hereinafter referred to as audio). And a power source 252 for supplying power to the system. Here, the inventors of the present application made a prototype of a lighting device having a function of emitting sound. When power is supplied from one power source to both the sensor system and the sound system, the human sensor module 21 and the sound module are used. It has been found that interference occurs with H.23. Therefore, in the present embodiment, the power supplied from the outside is branched and interference is suppressed by supplying power from the two power supply units (constant current power supply 251 and power supply 252) to the sensor system and the audio system, respectively. doing.

  The specific configuration of the power supply means 25 is not particularly limited as long as a power supply dedicated to the sensor system and a power supply dedicated to the audio system can be provided. As an example, in this embodiment, each of the constant current power source 251 and the power source 252 is configured by an AC-DC converter, and AC power supplied from the outside is branched and supplied to these power sources.

  As a process for suppressing the interference between the human sensor module 21 and the audio module 23, it is preferable to further perform an electromagnetic wave shielding process on each of the constant current power supply 251 and the power supply 252. Specifically, an insulating tape is wound around each of the constant current power source 251 and the power source 252, and a member having an electromagnetic wave shielding function is wound around and covered from the outside. Examples of the member having an electromagnetic wave shielding function include a metal foil such as an aluminum foil.

  Moreover, in the power supply means 25, the magnitude of the current flowing through the speaker 24 can be suppressed by separating the power supply dedicated to the sensor system and the power supply dedicated to the audio system. Specifically, when power is supplied to the speaker 24 from a power supply dedicated to the audio system, compared to the case where power is supplied from the single power supply to the sensor system and the audio system, the current flowing through the speaker 24 is large. Therefore, the amount of heat released from the speaker 24 can be reduced.

  Of the housing 10, the cover 11 is made of a light-transmitting material and transmits at least part of the light generated by the light source unit 22. The cover 11 is preferably formed of a resin material that is difficult to break even if it falls.

  The support 12 is formed of a resin material having good heat resistance, such as polypropylene (PP). A step 13 is provided on the inner peripheral surface of the support 12, and the illumination substrate 203 is disposed on the step 13, and the cover 11 is fitted to the support 12 to fix the illumination substrate 203 in the housing 10. Is done.

  A base 14 electrically connected to the power supply means 25 is provided at the end of the support 12 opposite to the side fitted with the cover 11 so as to be exposed to the outside of the support 12. ing. By screwing the cap 14 into a general light bulb socket, it is possible to supply power to the lighting device 1.

  A plurality of slits 15 for ventilation are formed on the outer peripheral surface of the support 12. Thereby, the sound generated from the speaker 24 can be propagated to the outside of the housing 10 and the heat generated from the electronic components accommodated in the housing 10 can be efficiently radiated to the outside. As described above, the illumination board 203 is formed of a metal such as aluminum, so that heat generated from the electronic components arranged on the cover 11 side than the illumination board 203 is released to the support body 12 side, and the slit 15 It becomes possible to dissipate heat efficiently.

  When the infrared sensor (PIR) 33 detects the presence of a living body, the transistor 34 is turned on, and power is supplied to the plurality of LED elements 35. Thereby, each LED element 35 emits light.

  When the infrared sensor 33 detects the presence of a living body, the photocoupler 36 as a switch and the transistor 37 are turned on, an audio signal is output from the audio module 38, and audio is generated from the speaker 39. The button switch 40 is provided for switching the type of the audio signal output from the audio module 38, and the type of the audio signal is changed each time the button switch 40 is pressed, and the audio message generated from the speaker 39 is changed. can do.

Can be used as Further, by installing the lighting device 1 set to emit a voice message “No smoking” in a plurality of languages, it can be used for announcements to customers. Here, there are cases where trouble occurs when the staff directly conveys the customer's attention and warning to the customer. However, an automatic voice message is expected to suppress the occurrence of the trouble. In addition, the lighting device 1, which is set to emit a voice message “Toilet is here” in multiple languages, can be used for announcements for foreign visitors to Japan by installing it in transportation facilities or tourist facilities. it can. In addition, by installing the lighting device 1 set to emit a voice message “no entry” in a plurality of languages, it can be used for intrusion prevention by installing in a passage to a place where entry is prohibited or a dangerous place. . Moreover, by attaching the lighting device 1 set so as to emit a siren to the entrance of a general household, it can be used as an alarm for informing a householder of a person who is going to go to midnight. Furthermore, it is also possible to use the lighting device 1 as an entertainment product by setting the lighting device 1 so as to emit a character of an animation program or a voice of a talent.
