In the automatic switch of the heat wave sensor attached to the document 1, when the hot line sensor 105 detects a human body, the control unit 165 turns on the opening and closing element 651 through the driving unit 650. An automatic switch with a hot line sensor is attached, and when the detected brightness of the brightness sensor 150 is darker than a preset brightness threshold ,, and the hot line sensor 105 detects the human body, during the action holding time, The lighting load 142 is illuminated. An automatic switch with a hot line sensor is provided, and with respect to the operation mode, there is a mode in which the illumination of the illumination load 142 is controlled by the hot line sensor 105. An automatic switch with a hot line sensor is attached, and regarding the operation mode, there is a mode in which the state of the illumination load 142 is continuously maintained regardless of whether the hot line sensor 105 detects the hot line. An automatic switch for the hot line sensor is provided, and the operation mode has a mode in which the state of the illumination load 142 is maintained until the operation holding time elapses. In the automatic switch to which the hot line sensor is attached, the control unit 165 switches the operation mode in accordance with the operation of the operation switch 161.

Further, the automatic switch with the hot line sensor attached to the document 1 includes an operation holding time setting unit 162 that sets the operation holding time, and a brightness sensor adjustment unit 163 that sets the brightness sensitivity level of the brightness sensor 150. An automatic switch with a hot line sensor is provided, and a DC stabilized power supply 656 that receives the commercial power source 141 and supplies the operating power source is provided.

In addition, as for the illumination system, as shown in FIG. 21, the structure of the switch 201, the slave unit 204, and the external device 205 which have the heating-wire sensing part connected to each illumination load 202 and 203 is already known (refer to Japan. Patent Publication No. 2006-331890). Japanese Patent Publication No. 2006-331890 is referred to as Document 2.

In the illumination system of Document 2, electric power from the commercial power source 241 is supplied to each of the illumination loads 202, 203 via the switch 201 of the heat-supply line sensing portion and is turned on. The switch 201 with the hot line sensing unit includes a sensing and detecting unit 212. The sensing and detecting unit 212 includes a hot line sensing unit 220 that detects a hot line from the human body, and an amplifier 221 that amplifies a signal from the hot line sensing unit 220. The sensing and detecting unit 212 has a comparing unit 222 and a signal processing unit 223 that generate a detection signal based on a signal from the amplifier 221. The sensing and detecting unit 212 is connected to the power supply circuit unit 211 and the signal processing unit 213 and operates by the power supplied from the power supply circuit unit 211. The external device 205 is connected to the signal processing unit 213, and outputs an external signal based on the user's operation to the signal processing unit 213. The slave unit 204 includes a hot line sensing unit and an illuminance sensor having the same functions as the hot line sensing unit 220 and the illuminance sensor 224 of the switch 201 of the hot line sensing unit. The slave 204 is provided, for example, at a place where there is no space in which the switch 201 of the hotline sensing unit is provided. The setting unit 215 variably sets the lighting illuminance and the extinguishing illuminance.

When it is determined that the detected illuminance of the illuminance sensor 224 is equal to or lower than the lighting illuminance, the signal processing unit 213 outputs a control signal to the output driving unit 214 to supply electric power to the illumination load 203 until the detection of the illuminance sensor 224 is performed. The illuminance is until the illuminance is extinguished. The signal processing unit 213 outputs a control signal for continuously supplying power to only the illumination load 203 among the plurality of illumination loads 202 and 203 without being affected by the detection result of the hot line sensing unit 220.

With the illumination system of Document 2, it is possible to prevent the lighting load from repeatedly lighting and extinguishing, and to stably illuminate the lighting load to obtain a fixed brightness.

In addition, the automatic switch attached to the hot line sensor of Document 1 can be switched from the mode in which the lighting load 142 is controlled by the hot line sensor 105 to the continuous lighting load 142 regardless of whether or not the hot line is detected by the operation of the operation switch 161.

The state sometimes makes the usability worse. The automatic switch attached to the hot wire sensor of Document 1 detects the human body in the hot line sensor 105, and in the mode in which the illumination load 142 is illuminated during the action holding time, since the character is still out after the porch The lighting load 142 is turned on during the operation holding time, which causes unnecessary power consumption. Further, in the illumination system of Document 2, only the technical contents of controlling the lighting and extinguishing of the illumination loads 202 and 203 by the operation of the external device 205 by the user are described. The automatic switch of the hotline sensor of the above-mentioned document 1 or the structure of the illumination system of the document 2 only considers the ease of use, and does not describe how to prevent the aforementioned unnecessary power consumption.

In order to save energy, the automatic switch with the hot wire sensor attached to the document 1 or the structure of the illumination system of the literature 2 is still insufficient, so further improvement is required. .

The switch mother machine 10 maintains the extinguished state of the illumination load 42 during the period of the shielding period 1M. The switch control section 410 of the base unit, for example, masked during the 1M, even at time t ₆ wire sensing unit 1 receives a sensing signal from the still lighting load off state 42 continues. Switch point 10, the elapsed time period t after the masked 1M _7, in response to a return from a wire sensing portion sensing signal to the lighting load 1 is turned on automatically turned off 42 mode.

The switch master 10 switches between the continuous lighting mode, the automatic lighting extinguishing mode, and the forced extinguishing mode each time the first operation switch 2a is operated. The mode display unit 6 displays "continuous lighting" in the continuous lighting mode. The mode display unit 6 displays "automatic" in the automatic light-off mode. The mode display unit 6 displays "cut" in the forced extinguish mode. The switch master 10 shifts each mode in the order of "cut", "automatic", and "continuously lit" in response to the switching of the operation mode.

The system 30 can perform power supply to the illumination load 42 side and stop of power supply by, for example, operating the operation slave unit 20 by a person remote from the switch base unit 10. In the switch master 10, the internal signal receiving unit 3 receives the communication signal from the operation unit 20, and the control unit 4 electrically connected to the signal receiving unit 3 switches the power supply to the illumination load 42 side based on the communication signal from the operation unit 20. And the power supply is stopped. In the automatic switching-off mode, for example, in the automatic lighting-off mode, when the power supply to the lighting load 42 side is stopped, the power supply to the lighting load 42 can be performed based on the communication signal from the operating sub-machine 20. That is, the control unit 4 of the switch master 10 lights the illumination load 42 in accordance with a transmission signal from the operation unit 20 in the automatic light-off mode. The control unit 4 starts lighting the lighting load 42 based on a transmission signal from the operating sub unit 20, and turns off the lighting load 42 after a predetermined lighting holding time has elapsed. In addition, the control unit 4 may be configured to sense the light from the hot line sensing unit 1 when the lighting load 42 is turned on during a predetermined lighting holding time period based on a signal transmitted from the operating unit 20. The input of the signal causes the predetermined lighting hold time to be re-timed again. The control unit 4 can extinguish the illumination load 42 after a predetermined lighting time elapses from the input timing of the sensing signal from the hot line sensing unit 1.

(Embodiment 2) The automatic switch system 30 to which the hot line sensor is attached in the present embodiment has the same configuration as that of the embodiment 1 shown in Figs. 1 and 2, except that the point in the embodiment 1 is shortened. The bright hold time is controlled by the reception of the communication signal from the operation slave unit 20, and the point at which the shutter 5 is immediately cut off is the main difference. The same components as those in the first embodiment will be denoted by the same reference numerals, and the description will be appropriately omitted.

In the system 30, only the control of the control unit 4 in the switch master 10 of the first embodiment is different, and the configuration is the same as that of the embodiment 1 shown in Fig. 1.

The control unit 4 of the switch master 10 controls the shutter 5 so that the illumination load 42 is turned on in response to a sensing signal from the hot line sensing unit 1, and is turned off after a predetermined lighting hold time elapses. When the illumination load 42 is turned on, the control unit 4 controls the cut-off switch 5 when the signal receiving unit 3 receives a transmission signal from the operation unit 20. In the system 30, the control unit 4 of the switch master 10 controls the cut-off switch 5 to turn off the lighting load 42.

Thereby, the system 30 can achieve more energy saving purposes.

Hereinafter, the operation of the switch master 10 in the system 30 will be described in detail with reference to FIG. The switch master 10 performs the same function as the operation from the time t ₁ to the time t ₃ of the switch master 10 in the first embodiment from the time t ₂₁ to the time t ₂₃ .

Next, the switch point 10, flickering in the automatic mode, when the lighting load 42 is lit, and the signal receiving section 3 at time t ₂₄ when the operation is received from the slave 20 to convey the signal, regardless of the lighting will be kept The lighting load 42 is turned off in time. In the switch master 10, the control unit 4 immediately controls the shutter at a time t ₂₄ that is earlier than the time t ₂₃ to the time t ₂₅ when the control unit 4 turns the illumination load 42 into the lighting state based on the sensing signal from the hot line sensing unit 1. 5. The lighting load 42 is turned off.

The switch master 10 is preferably provided to prohibit the control of the shutter 5 due to the sensing signal from the hot line sensing unit 1 between the predetermined periods when the signal receiving unit 3 receives the communication signal from the operation unit 20. The masking period is 2M. The masking period 2M can be set to the same time as the masking period 1M of the first embodiment. In the occlusion period 2M from the time t ₂₄ to the time t ₂₈ at which the illumination load 42 is turned off, for example, even if the control unit 4 receives the sensing signal from the hot line sensing unit 1 at time t ₂₆ , the switch unit 10 causes the control unit 4 to receive the sensing signal from the hot line sensing unit 1 at time t ₂₆ . The extinguished state of the lighting load 42 continues. Thereby, the switch master 10 can maintain the extinguishing state of the illumination load 42 between the shielding periods 2M. The switch master 10 returns to the automatic light-off mode after the occlusion period 2M elapses, so that the illumination load 42 can be illuminated in response to the sensing signal from the hot line sensing unit 1.

Further, in the switching master 2, for example, in the occlusion period 2M from the time t ₂₄ to the time t ₂₈ at which the illumination load 42 is turned off, the signal receiving unit 3 receives the communication signal from the operation slave unit 20 at time t ₂₇ , and controls The portion 4 turns the lighting load 42 into a lighting state. In other words, in the system 30, even if the hot line sensing unit 1 detects a hot line from the human body, the control unit 4 does not light the illumination load 42. In addition, in the occlusion period 2M, the control unit 4 has a rule that the communication signal from the operation unit 20 is more preferential than the detection signal from the hot line sensing unit 1 or the determination signal from the first input determination unit 2. It is applied to the control of lighting/extinguishing of the lighting load 42.

Thereby, the system 30 can control the lighting/extinguishing of the lighting load 42 in the automatic lighting-off mode. In the system 30, even when the hot line sensing unit 1 detects the person operating the operation unit 20, the lighting load 42 is not unnecessarily lit, and energy saving can be achieved. Further, in the system 30, for example, even if the operation unit 20 is provided in the detection area of the hot line sensing unit 1, the operation unit 24 can be operated to turn off the illumination load 42. The system 30 can also suitably utilize the constituent elements of the embodiment 1.

(Embodiment 3) The automatic switch system 30 with the hot line sensor of the present embodiment shown in Fig. 19 has the same configuration as that of the embodiment 1 of Fig. 1, and has an operation besides the operation unit 20 The sensing sub-machine 40 is the main difference. The same components as those of the first embodiment will be denoted by the same reference numerals, and the description will be omitted as appropriate.

The system 30 electrically connects the operating slave 20 and the sensing slave 40 to the switch master 10. The sensing slave 40 includes a third hot line sensing unit 45, a signal control unit 44, and a detection signal transmitting unit 43. The third hot line sensing unit 45 can detect the presence or absence of a human body. The third hot line sensing unit 45 can have the same structure as the hot line sensing unit 1 of the switch base unit 10. The signal control unit 44 controls the detection signal transmitting unit 43 based on the third sensing signal from the third hot line sensing unit 45. The detection signal transmitting unit 43 transmits a detection signal to the switch master 10 in accordance with the control of the signal control unit 44. The sensing sub-machine 40 can transmit the detection signal to the switch mother machine 10 in a wired manner, or can transmit the detection signal to the switch mother machine 10 in a wireless manner.

In the system 30, the sensing sub-machine 40 can be disposed at a position outside the detection area of the hot line sensing unit 1 of the switch main unit 10. In the sensing sub-machine 40, when the human body is detected in the detection area of the third hot line sensing unit 45, the signal control unit 44 controls the detection signal transmitting unit 43 to output a detection signal. The switch master 10, the signal receiving unit 3 constituting the inside can receive the detection signal from the sensing slave 40, and the control unit 4 electrically connected to the signal receiving unit 3 can cause the lighting load 42 based on the detection signal from the sensing slave 40. It becomes a structure that lights up.

The switch master 10 can supply power to the lighting load 42 based on the detection signal from the sensing slave 40, for example, when the power supply to the lighting load 42 side is stopped in the automatic lighting-off mode. That is, the control unit 4 of the switch master 10 lights the illumination load 42 based on the detection signal from the sensing slave 40 in the automatic light-off mode. The control unit 4 turns off the lighting load 42 from a point in time when the lighting load 42 is turned on based on the detection signal from the sensing slave unit 40. Further, when the illumination load 42 is turned on between the predetermined lighting holding times based on the detection signal from the sensing slave 40, the control unit 4 is based on the sensing signal from the hot line sensing unit 1. The input causes the established lighting hold time to be re-timed again. The control unit 4 can turn off the illumination load 42 after a predetermined lighting time has elapsed from the input of the sensing signal from the hot line sensing unit 1. The switch master 10 configures the signal receiving unit 3 to recognize the configuration of the communication signal from the operation slave unit 20 and the detection signal from the sensing slave unit 40, depending on the signal voltage. The system 30 can also suitably utilize the constituent elements of the embodiment 1 or the embodiment 2.
