  However, in the case of the conventional example, for example, in a place where there is a blocking object such as a door or a locker, such as a toilet having a hand washing area and a private room partitioned by a door, or a locker room where lockers are arranged, Due to the shielding, a non-detection region deviating from the human body detection region by the sensor is generated, and there is a disadvantage that the human body cannot be detected by the sensor and the light is turned off even though there is a person.

  The present invention has been made in view of such circumstances, and can prevent erroneous detection that a human body is absent due to a shielding object, and can avoid turning off in the presence of a person. The purpose is to do so.

  In order to achieve the above-described object, the invention according to claim 1 is a lamp that illuminates a specific space, and is lit by detecting the presence of a human body provided in the specific space. A human sensor that outputs a signal, and an illumination control unit that turns on the lamp in response to a lighting signal from the human sensor and turns off the lamp in response to the absence of a human body in the specific space; A non-detection region that is outside the human detection region by the human sensor in the specific space, detects the presence of a human body in the non-detection region, and outputs an auxiliary lighting signal An auxiliary sensor is provided, and the illumination control unit is configured to turn on the lamp in response to an auxiliary lighting signal from the auxiliary sensor.

  Further, the invention according to claim 2 is the illumination system according to claim 1, wherein the non-detection area includes an opening / closing door provided with a key, and the auxiliary sensor is connected with the key being in a locked state or an unlocked state. And an auxiliary lighting signal is output.

  According to a third aspect of the present invention, in the illumination system according to the first or second aspect, a weak radio is used as an auxiliary lighting signal that is wirelessly transmitted from the auxiliary sensor to the illumination control unit.

  Here, the weak radio means that the radio wave to be emitted is extremely weak, and the electric field strength is less than the value stipulated in Article 6 of the Radio Law Enforcement Regulations at a distance of 3 m from the transmission position (for example, specified at a frequency of 322 MHz or less). Electric field strength of 500 μV / m). In addition, although there is no regulation of frequency, generally it is often used in the range of 300 to 322 MHz.

  According to the illumination system of the first aspect of the present invention, the human body is detected in the non-detection region that cannot be detected by the human sensor in the specific space by the auxiliary sensor, and the human sensor is not detected by the human sensor. When the human body is detected, the lamp can be turned on. Therefore, it is possible to prevent erroneous detection that the human body is absent due to the shielding object, and it is possible to avoid unexpected turn-off in the presence of a person.

  According to the lighting system of the invention according to claim 2, when the specific space is, for example, a toilet, and has a hand washing area and a private room partitioned by a door as an open / close door as a non-detection area, the door When the key is in the locked state, attention is paid to the fact that a person is inside, and the locked state is determined and an auxiliary lighting signal is output so that the lamp is not turned off. In addition, when a specific space is a locker room and a non-detection area is created because it is blocked by the locker, there must be a person near the locker when the locker door is unlocked. By paying attention to the above, it is possible to determine the unlocked state and output an auxiliary lighting signal so that the lamp is not turned off.

  Further, according to the illumination system of the invention according to claim 3, by using the weak radio, there is no adverse influence as noise to the outside, and since the system is not restricted by the Radio Law, Can be built at low cost.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall plan view showing an arrangement configuration of a lighting system according to a first embodiment of the present invention, and FIG. 2 is a block diagram showing a system configuration of the first embodiment. As a specific space having a relatively wide hand washing place 1 A private room 4 partitioned by a door 3 as an opening / closing door is provided in the toilet 2, and a lighting fixture 6 having a lamp 5 for illuminating the inside of the toilet 2 is provided on the ceiling of the toilet 2. A main remote controller 8 is provided near the entrance 7 of the toilet 2, and an auxiliary remote controller 10 is provided near the key 9 of the door 3 of the private room 4.

  The main remote controller 8 includes a human sensor 11, a control unit 12, a wireless transmission unit 13, and a power supply unit 14. The human sensor 11 detects the presence of a human body based on a change in infrared rays in the human body detection region S in the toilet 2 (temperature change due to movement of the human body) and outputs a lighting signal. The lighting signal is transmitted to the wireless transmission unit 13. It transmits to the lighting fixture 6 as a radio signal by infrared rays or a radio wave through. Once the lighting signal is output, it is detected whether or not a human body exists at each set time, and the lighting signal is output when the presence of the human body is detected.

  In addition to the lamp 5, the lighting fixture 6 includes an illumination control unit 17 including a wireless reception unit 15 and a control unit 16, and a power supply unit 18. In the illumination control unit 17, the lighting signal from the human sensor 11 is received by the wireless reception unit 15, and in response thereto, a lighting output is output from the control unit 16 to the lamp 5 to control energization so that the lamp 5 is lit. It has become. After the lamp 5 is turned on once, the lighting holding time measuring timer is started, and if the lighting signal and an auxiliary lighting signal described later are not received within the lighting holding time, the lighting holding is automatically canceled without being reset. Thus, the lamp 5 is turned off.

  The auxiliary remote controller 10 includes a switch 19 as an auxiliary sensor, a control unit 20, a wireless transmission unit 21, and a power supply unit 22. The switch 19 detects the presence of a human body in a non-detection area outside the human body detection area S based on the lock state of the key 9 and outputs an auxiliary lighting signal. 21 is transmitted to the luminaire 6 as a radio signal by infrared rays or radio waves. Once the auxiliary lighting signal is output, it is detected whether or not a human body exists every set time, and the auxiliary lighting signal is output when the presence of the human body is detected. It is preferable to use weak radio as the auxiliary lighting signal.

  In the lighting control unit 17 of the lighting fixture 6, the auxiliary lighting signal from the switch 19 is received by the wireless receiving unit 15, and in response thereto, a lighting output is output from the control unit 16 to the lamp 5 to control energization, and the lamp 5 is turned on. It is supposed to be. That is, the lamp 5 is turned on in response to an auxiliary lighting signal from the switch 19.

  The control operation will be described with reference to the time chart of FIG. That is, when a person is outside the toilet 2 (outside the room), the lamp 5 is turned off. When a person enters the toilet 2 [room (space)], the presence sensor 11 detects (detects) the presence of the human body, outputs a lighting signal from the main remote controller 8, turns on the lamp 5, and keeps the lighting time Start the measurement timer. The presence / absence of the human body is detected by the human sensor 11 every set time set to a time shorter than the lighting holding time set by the lighting holding time measuring timer, and the lighting signal is received within the lighting holding time. At the same time, the lighting holding time measurement timer is reset and started, and the lighting state is maintained.

  Next, when a person enters the private room [indoor (private room)], the presence of the human body cannot be detected by the human sensor 11, but the switch 19 is turned on as the door 3 is closed and the key 9 is locked. The auxiliary lighting signal is output from the auxiliary remote controller 10 to turn on the lamp 5 and start the lighting holding time measurement timer. The presence / absence of the human body is detected by the human sensor 11 every set time set to a time shorter than the lighting holding time set by the lighting holding time measuring timer, and an auxiliary lighting signal is received within the lighting holding time. Accordingly, the lighting holding time measurement timer is reset and started, and the lighting state is maintained.

  When exiting the private room [indoor (private room)], the key 9 is unlocked, and the switch 19 is opened accordingly, and the auxiliary lighting signal is not output, but it enters the toilet 2 [indoor (space)] The presence sensor 11 detects (detects) the presence of the human body, outputs a lighting signal from the main remote controller 8 to maintain the lamp 5 in a lighting state, and starts a lighting holding time measuring timer. As described above, the presence / absence of the human body is detected by the human sensor 11 at every set time, and the lighting holding time measurement timer is reset and activated in response to receiving the lighting signal within the lighting holding time, and the lighting state is changed. maintain.

  Thereafter, when the user goes out of the toilet 2 (outside the room), neither the lighting signal nor the auxiliary lighting signal is output, and as the lighting holding time elapses, a turn-off signal is output by the lighting holding time measuring timer and the lamp 5 Turn off the light.

  FIG. 4 is an overall plan view showing the arrangement configuration of the lighting system according to the second embodiment of the present invention. The differences from the first embodiment are as follows.

  That is, the locker 32 is installed side by side in the locker room 31 as a specific space, and the infrared light from the human sensor 11 (see FIG. 2) of the main remote control 8 is blocked by the locker 32 in the space portion facing the locker 32, and the blind spot is formed. This is a non-detection area. The human sensor 11 detects that a person has entered the locker room 31 from the entrance 33 of the locker 32, outputs a lighting signal from the main remote controller 8, turns on the lamp 5, and starts a lighting holding time measurement timer. In response to receiving the lighting signal within the lighting holding time, the lighting holding time measuring timer is reset and started to maintain the lighting state.

  The locker 32 is provided with an open / close door 33, the open / close door 33 is provided with a key (corresponding to 9 in FIG. 2), and the auxiliary remote controller 10 (see FIG. 2) is provided on the locker 32 side. Contrary to 1, the presence of a human body in a non-detection area outside the human body detection area S is detected based on the unlocked state of the key, and an auxiliary lighting signal is output. Other configurations are the same as those of the first embodiment, and the description thereof is omitted by assigning the same reference numerals.

  In the control operation, as shown in the time chart of FIG. 5, in contrast to the first embodiment, the non-detection area [room (locker )]] Is detected and an auxiliary lighting signal is output, and the auxiliary lighting signal is transmitted to the lighting fixture 6 as a radio signal by infrared rays or radio waves through the wireless transmission unit 21, and the lighting signal from the main remote controller 8 is transmitted. Even if is not received, the lighting state is continued. Other operations are the same as those in the first embodiment.

  FIG. 6 is a block diagram showing a system configuration of the lighting system according to the third embodiment of the present invention. The differences from the first embodiment are as follows.

  That is, an illuminance sensor 41 that measures the illuminance of the toilet (indoor) and a lighting illuminance setting switch 42 that sets a lighting illuminance that is a threshold are provided, and the control unit 12 compares the measured illuminance with the set lighting illuminance. When the measured illuminance is larger than the set illumination illuminance, that is, when it is bright, the illumination signal is not output. Further, the controller 16 of the lighting fixture 6 is configured to emit a lighting output to the lamp 5 and turn on only when both the lighting signal and the auxiliary lighting signal are received. Other configurations are the same as those of the first embodiment, and the description thereof is omitted by assigning the same reference numerals.

  As the present invention, when applied to the locker room 31 of the second embodiment, as a modification of the third embodiment, the auxiliary remote controller 10 is provided with a forced lighting switch, and the forced lighting switch is turned on manually. Alternatively, the lamp 5 may be lit by outputting a lighting output only by the auxiliary lighting signal. Thereby, even if the inside of the locker room 31 is bright when the lamp 5 is turned off, the user of the locker 32 can forcibly turn on the lamp 5 when the locker 32 is blocked by the locker 32 in the vicinity of the locker 32 and dark. It is practically convenient.

  In the above embodiment, to detect the presence of a human body in the non-detection area outside the human body detection area S, the switch 19 determines whether the key 9 is in the unlocked state or the locked state. However, the presence of the human body in the non-detection region may be detected by an infrared sensor or the like, and these are referred to as auxiliary sensors. Further, in the above embodiment, the auxiliary remote controller 10 is provided in each of the private room 4 and the locker 32. However, the presence of a human body in a non-detection area including a plurality of private rooms 4 and the locker 32 is detected by an infrared sensor or the like. It may be configured so that the number of auxiliary remote controllers 10 can be reduced.
