In the switch master 10, the control unit 4 controls the switch 5 based on the sensor signal from the heat ray sensor unit 1 to turn on the illumination load 42. In the switch parent 10, the value of the counter of the timer unit is gradually decreased until a predetermined time elapses after the timer unit of the control unit 4 receives the sensor signal from the heat ray sensor unit 1. Predetermined time, referring to the time _{t 2} from time _{t 1} of FIG. In the switch parent device 10, after the time t ₂ when the counter value of the timer unit becomes “0”, the control unit 4 controls the switch 5 to turn off the illumination load 42. In other words, the switch parent 10 lights the lighting load 42 until a preset lighting holding time elapses.

Next, in the switch master 10, in the automatic light on / off mode, as in the time t ₁ , when the hot wire sensor unit 1 detects a change in the hot wire at the time t ₃ , the hot wire sensor unit 1 outputs a sensor signal. In the switch master 10, the control unit 4 controls the switch 5 based on the sensor signal from the heat ray sensor unit 1 to turn on the illumination load 42. Switch main unit 10 in the case of the automatic lighting off mode, lighting load 42 is in the lighting state, when receiving the signal receiver 3 at time t ₄ the transmission signal from the operating element 20, to shorten the turn-on duration. Switch main unit 10, from the time t ₃ when the control unit 4 by a sensor signal from the hot wire sensor unit 1 to the lighting state lighting load 42 by the timer counter value than the time t ₅ becomes "0" before the at time t _4, the control unit 4 is in unlit state lighting load 42 by controlling the switch 5. That is, the switch main unit 10, the lighting holding time from time _{t 3} to time _{t 5,} is reduced to from time _{t 3} to time _{t 4.}

Switch main unit 10, after a mask period 1M at time t _7, it returns to the automatic lighting off mode to allow light the lighting load 42 in response to the sensor signal from the hot wire sensor unit 1.

  Each time the first operation switch 2a is operated, the switch master 10 switches between the continuous lighting mode, the automatic lighting / unlighting mode, and the forced lighting mode. The mode display unit 6 displays “continuous on” in the continuous lighting mode. The mode display unit 6 displays “automatic” in the automatic on / off mode. The mode display unit 6 displays “OFF” in the forced extinction mode. In the switch parent device 10, each mode is repeatedly changed in the order of “OFF”, “AUTO”, and “CONTINUOUS ON” according to the switching of the operation mode.

  For example, even if the operating unit 20 is provided in the detection area of the heat ray sensor unit 1, the system 30 can turn off the illumination load 42 by operating the operating unit 20 by a person. The system 30 shortens the lighting holding time for lighting the lighting load 42 in the automatic lighting off mode.

That is, the control unit 4 of the switch parent 10 turns on the illumination load 42 by the transmission signal from the operation unit 20 in the automatic lighting / off mode. The controller 4 is turned off after a predetermined lighting holding time has elapsed since the lighting load 42 was turned on by a transmission signal from the operation unit 20. Further, when the control unit 4 keeps the lighting load 42 in the lighting state for a predetermined lighting holding time by the transmission signal from the operation unit 20, the control unit 4 inputs the predetermined lighting by the input of the sensor signal from the heat ray sensor unit 1. The holding time may be newly measured again. The control unit 4 can turn off the illumination load 42 after a predetermined lighting time has elapsed from the input of the sensor signal from the heat ray sensor unit 1.

(Embodiment 2)
The automatic switch system 30 with a heat ray sensor of the present embodiment has the same configuration as that of the first embodiment shown in FIG. 1 and FIG. 2, and instead of shortening the lighting holding time in the first embodiment, The main difference is that the switch 5 is immediately turned off by receiving the transmission signal. In addition, about the component similar to Embodiment 1, description is abbreviate | omitted suitably using the same code | symbol.

  This system 30 has the same configuration as that of the first embodiment shown in FIG. 1 except that the control of the control unit 4 in the switch parent 10 of the first embodiment is different.

  The control unit 4 of the switch parent 10 controls the switch 5 so that the illumination load 42 is turned on in accordance with the sensor signal from the heat ray sensor unit 1 and is turned off after a predetermined lighting holding time elapses. When the signal receiving unit 3 receives the transmission signal from the operation unit 20 when the lighting load 42 is in the lighting state, the control unit 4 turns off the switch 5 and controls it. In the present system 30, the control unit 4 of the switch parent unit 10 turns off the switch 5 to control the lighting load 42 to be turned off.

  Thereby, this system 30 can achieve further energy saving.

Below, operation | movement of the switch parent 10 in this system 30 is explained in full detail using FIG. The switch parent device 10 in the present system 30 functions in the same manner as the operation from the time t ₁ to the time t ₃ of the switch parent device 10 in the first embodiment from the time t ₂₁ to the time t ₂₃ .

Next, the switch main unit 10 in the case of the automatic lighting off mode, in the lighting load 42 is lit, when receiving the signal receiver 3 at time t ₂₄ the transmission signals from the operating element 20, regardless of the turn-on duration The illumination load 42 is turned off. Switch main unit 10, at time t ₂₄ before the time t ₂₅ from the time t ₂₃ to the control unit 4 by a sensor signal from the hot wire sensor unit 1 to the lighting state lighting load 42, the control unit 4 switch 5 Is immediately controlled to turn off the illumination load 42.

When the signal reception unit 3 receives the transmission signal from the operation unit 20, the switch base unit 10 is provided with a mask period 2M that prohibits the control of the switch 5 by the sensor signal from the heat ray sensor unit 1 for a predetermined period. It is preferable. The mask period 2M can be set to the same time as the mask period 1M of the first embodiment. Switch main unit 10, for example, in the mask period in 2M from the time t ₂₄ where the lighting load 42 to off state up to time t _28, be received from hot wire sensor unit 1 a sensor signal the control unit 4 at time t ₂₆ The lighting load 42 is kept off. Thereby, the switch master 10 can maintain the illumination load 42 in the extinguished state during the mask period 2M. Note that the switch parent device 10 returns to the automatic light on / off mode so that the illumination load 42 can be turned on in accordance with the sensor signal from the heat ray sensor unit 1 after the elapse of the mask period 2M.

In addition, the switch master unit 10 receives the transmission signal from the operating unit 20 at time t ₂₇ during the mask period 2M from time t ₂₄ to time t ₂₈ when the lighting load 42 is turned off. When receiving, the control part 4 makes the illumination load 42 into a lighting state. In other words, in the present system 30, the control unit 4 does not turn on the illumination load 42 even when the heat ray sensor unit 1 detects a heat ray from a human body. Further, in the system 30, the control unit 4 gives priority to the transmission signal from the operation unit 20 over the sensor signal from the heat ray sensor unit 1 and the determination signal from the first input determination unit 2 even during the mask period 2M. Thus, the lighting load 42 is used to control lighting / extinguishing.

  Thereby, this system 30 can control lighting / extinguishing of the illumination load 42 in the automatic lighting / extinguishing mode. The system 30 can save energy without unnecessarily lighting the illumination load 42 even when the heat ray sensor unit 1 detects a person operating the operation unit 20. Further, in the present system 30, for example, even if the operating unit 20 is provided in the detection area of the heat ray sensor unit 1, a person can operate the operating unit 20 to turn off the illumination load 42. The system 30 may appropriately use the components of the first embodiment.

(Embodiment 3)
The automatic switch system 30 with a heat ray sensor of this embodiment shown in FIG. 19 has the same configuration as that of Embodiment 1 of FIG. 1, and is mainly different in that a sensor slave unit 40 is provided in addition to the control unit 20. . In addition, about the component similar to Embodiment 1, description is abbreviate | omitted suitably using the same code | symbol.

  In the system 30, the operating unit 20 and the sensor unit 40 are electrically connected to the switch parent unit 10. The sensor slave unit 40 includes a third heat ray sensor unit 45, a signal control unit 44, and a detection signal transmission unit 43. The third hot wire sensor unit 45 can detect the presence or absence of a human body. The 3rd heat ray sensor part 45 can be set as the structure similar to the heat ray sensor part 1 of the switch parent 10. The signal control unit 44 controls the detection signal transmission unit 43 based on the third sensor signal from the third heat ray sensor unit 45. The detection signal transmission unit 43 transmits a detection signal to the switch parent device 10 under the control of the signal control unit 44. The sensor slave unit 40 may transmit the detection signal to the switch parent unit 10 by wire or may transmit the detection signal to the switch parent unit 10 wirelessly.

  In the system 30, the sensor slave unit 40 can be provided at a position outside the detection area in the heat ray sensor unit 1 of the switch master unit 10. When the sensor slave unit 40 detects a person in the detection area of the third heat ray sensor unit 45, the signal control unit 44 controls the detection signal transmission unit 43 to output a detection signal. In the switch master 10, the internal signal receiver 3 receives the detection signal from the sensor slave 40, and the controller 4 electrically connected to the signal receiver 3 is based on the detection signal from the sensor slave 40. The illumination load 42 is configured to be in a lighting state.

  For example, when the power supply to the illumination load 42 side is stopped in the automatic lighting / extinguishing mode, the switch parent device 10 can supply the illumination load 42 with the detection signal from the sensor slave unit 40. That is, the control unit 4 of the switch parent 10 turns on the illumination load 42 by the detection signal from the sensor slave 40 in the automatic light on / off mode. The control unit 4 is turned off after a predetermined lighting holding time has elapsed since the lighting load 42 was turned on by the detection signal from the sensor slave unit 40. Further, when the control unit 4 keeps the lighting load 42 in the lighting state for a predetermined lighting holding time by the detection signal from the sensor slave unit 40, the control unit 4 inputs the predetermined lighting by the input of the sensor signal from the heat ray sensor unit 1. Re-measure the holding time again. The control unit 4 can turn off the illumination load 42 after a predetermined lighting time has elapsed from the input of the sensor signal from the heat ray sensor unit 1. Note that the switch master 10 is configured such that the signal receiver 3 can discriminate between a transmission signal from the operation slave 20 and a detection signal from the sensor slave 40 based on a difference in signal voltage. The system 30 may appropriately use the components of the first embodiment and the second embodiment.
