Description

  The present invention relates to a lighting control system that detects the presence of a person in a specified detection area and controls the state of a lighting load.

  Conventionally, as shown in FIG. 4, a parent device 100 and a child device 200 each having a human sensor unit for detecting the presence or absence of a person in a detection area by detecting a heat ray radiated from a human body is connected to a signal line Ls. A lighting control system is known that controls the state of the lighting load of the lighting fixture L connected to the master unit 100 based on the detection signal of each human sensor unit (for example, Patent Document 1). reference). In the example shown in FIG. 4, a plurality of slave units 200 capable of so-called feed wiring are provided, and the slave units 200 are connected by feed wires. In the lighting control system shown in FIG. 4, the operation unit 300 is inserted between the master unit 100 and the lighting fixture L, and the operating unit 300 forcibly turns on the lighting load of the lighting fixture L. Operation enabling selection of continuous on mode, continuous cut mode for forcibly turning off the lighting load of the lighting fixture L, and automatic mode for turning on and off the lighting load of the lighting fixture L based on the output of the human sensor unit If the continuous on mode is selected by the operation unit, the lighting load is turned on (lights up). If the continuous off mode is selected by the operation unit, the lighting load is turned off (off), and if the automatic mode is selected. The parent device 100 controls the lighting load based on the output of each human sensor unit.

  In this type of lighting control system, when the master unit 100 is connected to the commercial power supply AC via the power line Lp ′ and a person is detected by the human sensor unit provided in the slave unit 200, detection that occurs in the slave unit 200 A signal is configured to be transmitted to the parent device 100 via the signal line Ls ′. The parent device 100 detects whether a person is detected by the human sensor unit provided in the parent device 100 or from the child device 200. When the detection signal transmitted via the signal line Ls ′ is received, the lighting load is controlled by controlling the switch element inserted between the commercial power source and the lighting fixture L to supply power to the lighting fixture L from the commercial power source. Turn it on.

  Therefore, for example, as shown in FIG. 5, the lighting fixture L is arranged on the ceiling surface Z on the indoor side of the entrance, the master unit 100 is arranged on the wall surface Y on the indoor side of the entrance, and the slave unit 200 is installed in the entrance store. If it is arranged on the eaves lower surface X on the outside, the lighting load of the luminaire L on the indoor side of the front door is detected regardless of whether the human sensor 100 of the parent device 100 or the human sensor 200 of the child device 200 is detected. The lighting load of the lighting fixture L on the indoor side of the entrance is turned on even when a person enters the detection area E of the human sensor unit of the child device 200 when no house occupant is present. As a result, the suspicious person can be intimidated by giving the impression that there is a family member. Further, even when the house resident is at home, the lighting load of the lighting fixture L on the indoor side of the entrance is turned on when the occupant is detected by the human sensor 100 of the parent device 100, so that a threatening effect on the suspicious person is obtained. can get.

  Further, conventionally, there is a brightness sensor unit for detecting ambient brightness and a human sensor unit, as shown in FIG. 6A, such as a porch light arranged on the outer wall surface W on the outdoor side of the entrance. The lighting fixture L1 ′ and the lighting fixture L2 ′ such as a ceiling light that has a human sensor part and is arranged on the ceiling surface Z on the indoor side of the entrance are connected via a signal line Ls ″ as shown in FIG. Connected and configured so that the outdoor side lighting fixture L1 and the indoor side lighting fixture L2 ′ can be linked and controlled when a person is detected by the human sensor unit provided on the outdoor side lighting fixture L1 ′. Illuminated lighting control systems are known.

  In this lighting control system, the lighting load of the lighting fixture L1 ′ is reduced when the lighting state of the lighting fixture L1 ′ is forcibly turned on and the brightness detected by the brightness sensor unit is smaller than the threshold value. Normal mode (greeting mode) for lighting the lighting load of the lighting fixture L1 ′ when the person is detected by the human sensor unit of the lighting fixture L1 ′ after lighting (dimming lighting) and illumination on the outdoor side A dedicated remote control device (not shown) for selecting a crime prevention mode in which the lighting loads of the respective lighting fixtures L1 ′ and L2 ′ are simultaneously turned on when a person is detected by the human sensor unit provided in the fixture L1 ′. ). Therefore, when a person is detected by the human sensor unit of the outdoor lighting fixture L1 ′ in the state where the security mode is set, the lighting load of the outdoor lighting fixture L1 ′ and the indoor lighting fixture L2 Since the lighting load is turned on at the same time, the suspicious person can be intimidated by giving the impression that there is a family member. In the lighting control system shown in FIG. 7, a switch F that is a wiring fixture for forcibly turning on and off the lighting load of the outdoor side lighting fixture L1 ′ and is partially embedded in the wall surface is installed. It is a wiring fixture that is inserted between the outside lighting fixture L1 ′ and the commercial power supply AC and forcibly turns on / off the lighting load of the indoor lighting fixture L2 ′, and is attached in a form that is partially embedded in the wall surface. The switch G is inserted between the indoor lighting fixture L2 ′ and the commercial power source AC.

In addition, a crime prevention system has been proposed that is configured to turn on the luminaire placed on the indoor side of the entrance with a delay and to sound an alarm buzzer when a human body is detected by a sensor provided on the outside side of the entrance. (For example, refer to Patent Document 2).
JP 2002-289375 A JP 2004-280175 A

  By the way, in the lighting control system shown in FIG. 5 and FIG. 7, since the indoor lighting fixtures L ′ and L2 ′ are turned on immediately when a person is detected by the human sensor unit on the outdoor side of the entrance, There is a concern that it is easy to understand that the indoor lighting fixtures L ′ and L2 ′ are turned on according to the detection result of the human sensor unit, and that the suspicious person can easily catch the absence of a householder when absent.

  Further, in the crime prevention system disclosed in Patent Document 2, although the alarming buzzer sounds, the threatening effect on the suspicious person is increased, but there is a risk that the householder and the customer will be uncomfortable when the householder returns home or visits the customer. At the same time, it becomes a nuisance to neighboring neighbors.

  The present invention has been made in view of the above reasons, and its purpose is to make it easier for a suspicious person approaching the outdoor side of a front door when a resident is absent to make it easier for a resident to be absent. It is another object of the present invention to provide a lighting control system that is capable of preventing discomfort to the householder and the customer when the householder returns home or visits the customer.

  Invention of Claim 1 is the outdoor side illumination load arrange | positioned at the outdoor side of a front door, the indoor side illumination load arrange | positioned at the indoor side of a front door, the 1st output drive part which drives an outdoor side illumination load, The outdoor human sensor unit that detects the presence of a person in the specified detection area on the outdoor side of the entrance and generates a detection signal, and controls the first output driving unit based on the output of the outdoor human sensor unit A first signal processing unit that performs, a second output drive unit that drives an indoor lighting load, and an indoor person that detects the presence of a person within a specified detection area on the indoor side of the entrance and generates a detection signal A sensor unit, a second signal processing unit for controlling the second output driving unit based on outputs of the outdoor side human sensor unit and the indoor side human sensor unit, and a voice for outputting voice on the indoor side of the entrance An output device and a voice message registration unit for pre-registering voice messages for reception The second signal processing unit functions as a function when receiving the detection signal generated by the outdoor human sensor unit in a state where the operation mode is set to the crime prevention mode, and performs the second output drive after a predetermined delay time. And a function to turn on the indoor lighting load by controlling the unit, and a function to output a voice message for reception registered in the voice message registration unit from the voice output device.

  According to the present invention, in a state where the operation mode of the second signal processing unit is set to the crime prevention mode, when a suspicious person enters the detection area of the outdoor human sensor unit and a detection signal is generated, a predetermined signal is generated. The indoor lighting load is turned on after the delay time, and the voice message for reception registered in the voice message registration unit is output from the voice output device, so that it approaches the outdoor side of the entrance when the house is absent. Compared to the case where the indoor lighting load is immediately turned on when the suspicious person enters the detection area of the outdoor human sensor unit as compared to the conventional case, the effect of directing the home of the resident is greater. It becomes higher and it becomes possible to make it easier for the absence of the housekeeper to be caught, and compared to the conventional crime prevention system that sounds an alarm buzzer, it is more difficult for the housekeeper and the visitor when the housekeeper returns or visits the visitor. Less likely to give a sense.

  According to a second aspect of the present invention, in the first aspect of the present invention, the voice message registration unit stores a plurality of types of voice messages for reception, and the second signal processing unit has an operation mode of the crime prevention mode. When a detection signal generated in the outdoor human sensor unit is received even after a lapse of a specified time since a voice message for reception is output from the voice output device in a state set to The voice message is output from the voice output device.

  According to the present invention, since a plurality of types of voice messages are output from the voice output device with a time lapse, it is possible to make it more difficult for a suspicious person to take away the absence of a family member.

  In the invention of claim 1, it is possible to make it easier for a suspicious person approaching the outdoor side of the entrance when no house resident is present to detect the absence of the house clerk compared to the prior art. This has the effect of making it less likely to cause discomfort to the family members and customers when visiting.

(Embodiment 1)
As shown in FIGS. 1 and 2, the lighting control system of the present embodiment includes two human-sensitive automatic switches A and B, and each human-operating automatic switch A and B includes a lighting load, respectively. , L2 are connected via power supply lines Lp, Lp. Here, the human sensitive automatic switch A and the lighting fixture L1 are attached to the lower surface X of the eaves, for example, on the outdoor side of the entrance, the human sensitive automatic switch B is attached to the wall Y on the indoor side of the entrance, and the lighting fixture L2 is the entrance of the entrance. It is attached to the ceiling surface Z on the indoor side. In addition, in this embodiment, the illumination load of the lighting fixture L1 comprises the outdoor side lighting load arrange | positioned at the outdoor side of a front door, and the lighting load of the lighting fixture L2 is the indoor side lighting load arrange | positioned at the indoor side of a front door. It is composed. Here, the human sensitive automatic switch A and the lighting fixture L1 are not limited to those attached to the eaves lower surface X as long as they are on the outdoor side of the entrance, and may be attached to, for example, an outer wall surface.

  The human-sensing automatic switches A and B include human sensor units 1a and 1b using pyroelectric infrared sensors (hereinafter referred to as pyroelectric sensors) 11a and 11b that detect heat rays from the human body, CdS, and photodiodes. The brightness sensors 2a and 2b for detecting the ambient brightness by the brightness sensors 21a and 21b using the sensor, the outputs of the human sensor 1a and 1b and the outputs of the brightness sensors 2a and 2b are input. It includes signal processing units 3a and 3b mainly composed of a computer. In the present embodiment, the human sensor 1a constitutes an outdoor human sensor, the human sensor 1b constitutes an indoor human sensor, and the signal processor 3a is a first signal processor. The signal processing unit 3b constitutes a second signal processing unit.

  The human sensor units 1a and 1b amplify the outputs of the pyroelectric sensors 11a and 11b, and trigger signals (detection signals) when the outputs from the amplifiers 12a and 12b are larger than a reference value. Comparators 13a and 13b for output are provided, and trigger signals output from the comparators 13a and 13b are input to the signal processors 3a and 3b. The signal processing units 3a and 3b include a timer unit that constitutes part of the human sensor units 1a and 1b. The timer unit limits a predetermined holding time each time a trigger signal is input. In other words, the timer unit is retriggerable, and if the next trigger signal is input while the trigger signal is input and the holding time is timed, the holding time is timed again from the trigger signal. Therefore, if there is a person in the detection area set corresponding to the pyroelectric sensors 11a and 11b and there is a person's movement during the holding time period, the timer unit will continue the timed operation. In addition, since the period during which the timer unit continues the timed operation can be regarded as a period in which a person exists in the detection area, the period during which the timer unit continues the timed operation inside the signal processing units 3a and 3b. The representing signal is generated as a human body detection signal.

  The brightness sensors 2a and 2b amplify the outputs of the brightness sensors 21a and 21b, and when the outputs from the amplifiers 22a and 22b are larger than a threshold value, a high level signal (hereinafter, bright) Comparators 23a and 23b that output a low level signal (hereinafter referred to as a dark state signal) when the signal is equal to or lower than a threshold value, while the output of the comparators 23a and 23b is signal processing. (The threshold value is set in two stages, one threshold value is a dark transition threshold value for detecting that the surrounding has shifted from a bright state to a dark state, and the other is dark in the surroundings) A bright transition threshold for detecting the transition from the state to the bright state, and the bright transition threshold is set on the brighter side than the dark transition threshold).

  Electricity is supplied from the commercial power supply AC through the power supply circuits 4a and 4b to the human sensor units 1a and 1b, the brightness sensor units 2a and 2b, the signal processing units 3a and 3b, and a speaker 6b described later. That is, a pair of power supply terminals T1a and T1b for connection to the commercial power supply AC are connected to the power supply circuits 4a and 4b.

  The signal processing units 3a and 3b control the output driving units 5a and 5b by combining the above-described human body detection signal and a bright state signal or a dark state signal. The output drive units 5a and 5b include a switch element inserted into a power feeding path from the commercial power supply AC to the lighting fixtures L1 and L2 including the lighting load. The state of the switch element is from the signal processing units 3a and 3b. Controlled by a control signal.

  One end of the switch element included in the output drive units 5a and 5b is connected to the power supply terminals T1a and T1b through the power supply circuits 4a and 4b, and the other end of the switch element is connected to the load terminals T2a and T2b. Therefore, the power supply lines Lp and Lp serving as power feeding paths between the commercial power supply AC and the lighting fixtures L1 and L2 are provided between the commercial power supply AC and each pair of power supply terminals T1a and T1b, and the lighting fixtures L1 and L2 and the load terminals T2a, Each of them is connected to T2b. The lighting fixture L1 uses a dimmable lighting load such as an incandescent lamp, and the lighting fixture L2 uses a fluorescent lamp. The switch element included in the output drive unit 5a includes a triac and an output. The switch element included in the drive unit 5b is a relay contact. In addition, the signal processing unit 3a can control the light output of the lighting load of the lighting fixture L1 by controlling the phase of the triac that is a switch element of the output driving unit 5a and adjusting the power supplied to the lighting fixture L1, and the lighting fixture L1. There is a case where the lighting load is turned on at rated power and a case where dimming lighting (dimming lighting) is performed.

  Here, the human sensitive automatic switch A is a lighting apparatus based on the output of the human sensor 1a, the output of the brightness sensor 2a, and a preset welcome time as the operation mode of the signal processor 3a. A welcome mode for controlling the state of the L1 lighting load, a cutting mode for forcibly turning off the lighting load of the lighting fixture L1, and turning on the lighting load of the lighting fixture L1 (rated lighting state). The continuous entry mode to be maintained can be set by an external dedicated operation unit. When the operation mode is set to the welcome mode, the signal processing unit 3a darkens the surroundings of the human sensitive automatic switch A and the output of the brightness sensor unit 2a changes from the bright state signal to the dark state signal. , The lighting load of the luminaire L1 is dimmed so that the light output is 10% of the rated lighting regardless of the output of the human sensor unit 1a, and the waiting time is limited by the internal timing means. Is started, and the lighting load of the lighting fixture L1 is extinguished when the time limit of the meeting time is over. Here, when the surroundings of the human sensitive automatic switch A are dark, the signal processing unit 3a, when the trigger signal from the human sensor unit 1a is input, regardless of whether or not the welcome time has elapsed, the lighting fixture L1. Is switched to the rated lighting state, and the switch element of the output drive unit 5a is controlled so that the lighting load of the lighting fixture L1 is maintained in the rated lighting state while the human body detection signal is generated. Therefore, if the meeting time is set in advance, when the surroundings become dark, the lighting load of the outdoor lighting device L1 is dimmed and the lighting load of the outdoor lighting device L1 is adjusted during the time of the meeting time. Since it can be turned on, it is possible to greet the housekeeper and the visitor by the illumination light of the lighting load of the outdoor side lighting apparatus L1, and before detecting the housekeeper and the visitor by the human sensor unit 1a Because the lighting load of the lighting fixture L1 on the outdoor side is dimmed, it becomes possible to prevent the dwellers and visitors from being dazzled or surprised, and in addition to the time of the meeting If the surroundings are dark and the human sensor 1a detects a person, the lighting load of the outdoor lighting fixture L1 is immediately rated and lit, thus preventing crime. In addition, the human sensitive automatic switch A is provided with a mode changeover switch for setting the above-described operation mode and a reception time setting unit (for example, a variable resistor) for setting the reception time and connected to the signal processing unit 3a. May be.

  By the way, the lighting control system of this embodiment can control the outdoor side lighting fixture L1 and the indoor side lighting fixture L2 separately, and the indoor side lighting fixture L2 is interlocked with the outdoor side lighting fixture L1. In this way, the indoor lighting fixture L2 can be controlled. That is, a pair of signal output terminals T3a are connected to the signal processing unit 3a of the human sensitive automatic switch A, and a pair of signal input terminals T3b are connected to the signal processing unit 3b of the human sensitive automatic switch B. The pair of signal output terminals T3a of the human-sensing automatic switch A and the pair of signal input terminals T3b of the human-sensing automatic switch B are connected via a two-wire signal line Ls. Therefore, the detection signal of the human sensor 1a of the outdoor human-type automatic switch A is input to the signal processing unit 3b of the human human-type automatic switch B via the signal line Ls. ing.

  Furthermore, the human sensitive automatic switch B is based on the off mode in which the lighting load of the lighting fixture L2 is forcibly turned off (off), the output of the human sensor unit 1b, and the output of the brightness sensor unit 2b. An automatic mode for turning on / off the lighting load of the lighting fixture L2, a crime prevention mode for turning on / off the lighting load of the lighting fixture L2 based on the outputs of the human sensor units 1a, 1b and the brightness sensor unit 2b, and illumination Connected to the signal processing unit 3b is a mode selector switch (not shown) consisting of a slide-type switch capable of selecting four modes including a continuous on mode for forcibly turning on the lighting load of the appliance L2 (rated lighting state). The operation switch 43 (see FIG. 3) of the mode switch is exposed on the front side of the container 40 (see FIG. 3). Therefore, the housekeeper can easily operate the operation unit 43 on the indoor side of the entrance. For example, when the user wants to set the crime prevention mode when going out, the operation unit 43 may be operated and set to the automatic mode after returning home. In addition, on the front surface of the container 40, as shown in FIG. 3B, “OFF”, “AUTO”, which indicates which of the above four modes is set, as shown in FIG. “Crime prevention” and “continuous entry” are written.

  Here, as a function when the trigger signal (detection signal) generated in the outdoor human sensor unit is received in a state where the operation mode is set to the crime prevention mode, the signal processing unit 3b functions as a function after a predetermined delay time. It has a function of lighting the lighting load of the lighting fixture L2 by controlling the output driving unit 5b. The signal processing unit 3b has a timer unit (hereinafter referred to as a delay unit) for timing the delay time separately from a timer unit (hereinafter referred to as a retention timer unit) for limiting the retention time. Timer section).

  The body 40 of the human sense automatic switch B is formed in a module size of three large square connecting wiring devices that can be attached to a mounting frame for three large square connecting wiring devices standardized by JIS standards. ing. In other words, the container body 40 is formed to have a size corresponding to three of the unit-type embedded wiring devices that can be connected to and attached to the mounting frame for the embedded wiring device. Yes. Therefore, only one container 40 can be attached to the attachment frame. FIG. 3A shows a state in which a plate 50 having an opening window that is longer and wider than an instrument mounting window hole in the mounting frame is overlapped on the front side of the mounting frame. Here, the plate 50 is comprised by the plate frame attached to the front side of a mounting frame, and the decorative plate attached to the front side of a plate frame. A light receiving lens 45, which is a light receiving optical system for setting the detection area of the pyroelectric sensor 11b and the detection area of the brightness sensor 21b, is disposed on the front side of the body 40.

  In addition, a speaker 6b constituting an audio output device that outputs audio on the indoor side of the entrance is disposed in the body 40 of the human-sensing automatic switch B, and the signal processing unit 3b is configured to receive audio for reception. As a voice message registration unit for registering a message in advance, a memory (not shown) capable of recording voice is provided, and the human sensor of the human-type automatic switch A on the outdoor side when the crime prevention mode is set As a function when the trigger signal (detection signal) output from the unit 1a is input, it has a function of outputting a voice message for reception registered in the memory from the speaker 6b.

  In the voice message, a voice message “Return” is registered as the first voice message and a voice message “Done” is registered as the second voice message. However, the number of voice messages to be registered is two. The voice message is not limited to “Return” or “Done”, but may be a language for responding to the return of the home or a visitor. It should be noted that a voice input device such as a microphone may be provided in the human sensitive automatic switch B so that a voice message of a householder can be recorded and registered.

  Hereinafter, the operations of the signal processing units 3a and 3b of the human sensitive automatic switches A and B will be described together.

  As described above, the signal processing unit 3a of the human-sensing automatic switch A arranged on the outdoor side has a bright state signal output from the brightness sensor unit 2a when the welcome mode is set as the operation mode. The output drive unit 5a is controlled by a combination of a dark state signal and a trigger signal (detection signal) output from the human sensor unit 1a.

  Here, when the welcome mode is set as the operation mode, the switch of the output drive unit 5a does not depend on the output of the human sensor unit 1a during the period when the bright state signal is generated from the brightness sensor unit 2a. The element is turned off, and the lighting load of the lighting fixture L1 is turned off. Therefore, during a period when the surroundings are bright and the lighting fixture L1 does not need to be turned on, the lighting fixture L1 is kept off.

  On the other hand, during a period when the dark state signal is generated from the brightness sensor unit 2a, the output driving circuit 5a is in a state of supplying power from the commercial power supply AC to the lighting fixture L1, and the lighting fixture L1 is turned on. Here, in the period until the time limit of the welcome time ends and the human body detection signal is not generated, the signal processing unit 3a gives the output drive unit 5a a control signal for instructing dimming lighting, The lighting load of the appliance L1 is dimmed. Further, when a detection signal is generated in the human sensor unit 1a, the signal processing unit 3a gives a control signal instructing rated lighting to the output driving unit 5a so that the lighting load of the lighting fixture L1 is rated-lit. Here, the rated lighting state is continued only during the period in which the above-described human body detection signal is generated. The signal processing unit 3a gives a control signal to instruct the dimming lighting to the output driving unit 5a when the human body detection signal is not generated during the time of the meeting time (when the holding timer unit ends) The illumination load of the appliance L1 returns to dimming again. In this way, during the period when the dark state signal is generated from the brightness sensor unit 2a, the lighting load of the lighting fixture L1 becomes rated lighting only during the generation period of the human body detection signal, and the human body is detected during the time of the welcome time. During the non-generation period of the signal, the lighting load of the lighting fixture L1 is dimmed.

  As described above, the signal processing unit 3a of the human-side automatic switch A on the outdoor side turns on the luminaire L1 when the surroundings become dark when the welcome mode is set, and the person detects the human-sensing sensor unit 1a. The lighting load of the lighting fixture L1 is set to the rated lighting during the period in the detection area, and the lighting load of the lighting fixture L1 is set to the dimming lighting during the period when the person is not present in the detection area during the time of the meeting time. If it is after the time of the welcome time, the lighting load of the lighting fixture L1 is turned off.

  On the other hand, the signal processing unit 3b of the human-sensing automatic switch B arranged on the indoor side has a bright state signal and a dark state output from the brightness sensor unit 2b when the automatic mode is set. The brightness sensor unit is configured to control the output driving unit 5b by a combination of the signal and the trigger signal (detection signal) output from the human sensor unit 1b, and the security mode is set. The output drive unit 5b is controlled by a combination of a bright state signal and a dark state signal output from 2b and a trigger signal (detection signal) output from the human sensor units 1a and 1b.

  Here, when the automatic mode is set as the operation mode, the signal processing unit 3b outputs a period during which the bright state signal is generated from the brightness sensor unit 2b regardless of the output of the human sensor unit 1b. The switch element of the drive unit 5b is turned off, and the lighting load of the lighting fixture L2 is turned off. Therefore, the lighting fixture L2 is kept off during a period when the surroundings are bright as in the daytime and it is not necessary to turn on the lighting fixture L2.

  On the other hand, during the period when the dark state signal is generated from the brightness sensor unit 2b, the signal processing unit 3b is turned on (that is, the switch element is turned on only in the period when the human body detection signal is generated by the detection signal of the human sensor unit 1b) , Lighting control of the lighting load) is given to the output drive unit 5b to light the lighting load of the lighting fixture L2. Here, the lighting state of the lighting load of the indoor lighting fixture L2 is continued only during the period in which the above-described human body detection signal is generated. When the human body detection signal is not generated (when the time limit of the holding timer unit ends), the signal processing unit 3b gives the output drive unit 5b a control signal that instructs the switch element to be turned off (that is, the lighting load is turned off). The lighting load of the lighting fixture L2 is turned off. Thus, during the period when the dark state signal is generated from the brightness sensor unit 2b, the illumination load of the lighting fixture L2 is turned on only during the generation period of the human body detection signal.

  In addition, when the crime prevention mode is set as the operation mode, the signal processing unit 3b receives the detection signal generated by the human sensor 1a of the human sensor automatic switch A on the outdoor side. Regardless of the output of 2b, after the time limit of the delay time by the delay timer unit, a control signal instructing turning on of the switch element (that is, lighting of the lighting load of the indoor lighting fixture L2) is given to the output driving unit 5b When the lighting load of the lighting fixture L2 is turned on and the human body detection signal is no longer generated (when the time limit of the holding timer unit ends), the switch element is turned off (that is, the lighting load is turned off) to the output driving unit 5b. The control signal to instruct | indicate is given and the lighting load of the lighting fixture L2 is light-extinguished. In addition, when the crime prevention mode is set, the signal processing unit 3b outputs the brightness sensor unit 2b when a detection signal generated by the human sensor unit 1b of the indoor human-type automatic switch B is input. Regardless of the, the switch element is turned on (that is, the lighting load of the lighting fixture L2 on the indoor side is turned on) is supplied to the output drive unit 5b to turn on the lighting load of the lighting fixture L2, and the human body detection signal is If it does not occur (when the time limit of the holding timer unit ends), a control signal that instructs the output drive unit 5b to turn off the switch element (that is, turn off the lighting load) is given to turn off the lighting load of the lighting fixture L2. .

  Further, when the crime prevention mode is set as the operation mode, the signal processing unit 3b receives the first sound when the detection signal generated by the human sensor unit 1a of the human sensor automatic switch A on the outdoor side is input. A message (here “return”) is output from the speaker 6b, and the human sensor unit 1b after a lapse of a specified time (for example, within a range of 30 seconds to 5 minutes) from the output time. When the detection signal generated in step S3 is received, a second voice message different from the first voice message (here, “who”) is output from the speaker 6b, and a different voice message for reception is output as the voice message. When the detection signal generated by the human sensor unit 1b is received even after a specified time has elapsed since the output, the voice message is different from the second voice message. (Here, the first voice message) to output. In addition, the timing which outputs a 1st audio | voice message from the speaker 6b initially may be synchronized with the timing which lights the lighting load of the lighting fixture L2, and may be shifted.

  In the lighting control system of the present embodiment described above, as described above, in the state where the signal processing unit 3b of the indoor human-sensing automatic switch B is set to the crime prevention mode, the outdoor human-sensing automatic As a function when the detection signal generated in the human sensor unit 1a of the switch A is received, the function of controlling the output driving unit 5b after a predetermined delay time to light the lighting load of the indoor lighting fixture L2, and the above It has a function of outputting a voice message for reception registered in the memory in advance from the speaker 6b.

  Therefore, in the lighting control system of the present embodiment, in the state where the operation mode of the signal processing unit 3b is set to the crime prevention mode, the suspicious person detects the human sensor unit 1a of the human sensitive automatic switch A on the outdoor side. When a detection signal is generated after entering the area, the lighting load of the indoor lighting fixture L2 is turned on after a predetermined delay time, and a voice message for reception registered in the memory in advance is output from the speaker 6b. Therefore, when a suspicious person enters the detection area of the outdoor human sensor, the indoor lighting load is applied to a suspicious person who approaches the outdoor side of the entrance when no housekeeper is present. Compared to when it lights up immediately, the production effect of directing the home of the householder is enhanced, making it possible to make the absence of the householder more difficult to take, and the alarm buzzer sounds like in the past As compared to the case in the stem, there is an advantage that it becomes difficult to give an unpleasant feeling to Iejin and their customers at the time of visit of returning home or when the guests of the family member.

  In addition, a plurality of types of voice messages for response are registered in the memory, and the signal processing unit 3b causes the speaker 6b to output voice messages for response when the operation mode is set to the security mode. When a detection signal generated by the human sensor unit 1a on the outdoor side is received even after the lapse of a specified time after that, since a different voice message for reception is output from the speaker 6b, the absence of a householder can be further increased. It becomes possible to make it difficult.
