Illuminance sensor setting device
View Patent ↗An illuminance sensor setting device includes: an illuminance sensor that outputs a signal for switching a lighting apparatus, and a setting unit that performs setting of the illuminance sensor. The illuminance sensor and the setting unit are provided separately from each other, and are connected to signal lines. The setting unit has a configuration to set a sensor address of the sensor, a control address of the lighting apparatus, and an illuminance reference for switching the lighting apparatus. The setting unit transmits to the signal line the setting signal and the sensor address. Thus, even if the illuminance sensor is provided on, for example, the ceiling in the vicinity of the lighting apparatus, the setting unit can be provided at any place, such as a wall, where the setting unit can be easily operated, and work for settings is facilitated.
1. An illuminance sensor setting device comprising:
an illuminance sensor which detects the illuminance value of ambient illuminance and outputs a signal to control a lighting apparatus so as to light up or extinguish the lighting apparatus in accordance with the detected illuminance value; and
a setter configured to perform operation settings of the illuminance sensor, wherein
the illuminance sensor and the setter are provided separately from each other, and connected to a transmission signal line in a lighting control system,
the setter is configured to set an illuminance sensor address of the illuminance sensor, a control address of the lighting apparatus, and an operation illuminance,
the illuminance sensor address, set through the setter, is shared by the illuminance sensor and the setter,
when the settings have been performed, the setter is configured to transmit, to the transmission signal line, a setting signal indicating the settings, together with an information signal indicating the illuminance sensor address, and
the illuminance sensor, when the illuminance value detected by the sensor has reached the operation illuminance, is configured to transmit, to the transmission signal line, an information signal indicating the control address, and a control signal for lighting up or extinguishing the lighting apparatus.
2. The illuminance sensor setting device according to claim 1 , wherein a transmitter which transmits the control signal, and a signal transmitted between the illuminance sensor and the setter, is connected to the transmission signal line.
3. The illuminance sensor setting device according to claim 2 , wherein
the illuminance sensor comprises a plurality of the illuminance sensors, and
the setter is configured to set illuminance sensor addresses of the plurality of illuminance sensors.
4. The illuminance sensor setting device according to claim 3 , wherein
each of the plurality of illuminance sensors comprises a sensor switch to turn on or off an illuminance detection function of the illuminance sensor, and
the setter has an operation switch to turn on or off the illuminance detection function of the illuminance sensor.
5. The illuminance sensor setting device according to claim 4 , wherein
when one of the sensor switch and the operation switch is pressed and held, switching of the illuminance detection function by the pressing and holding is held in a priority state, so that after the switching, even if the other one of the sensor switch and the operation switch is normally pressed, the state of the illuminance detection function is not switched.
6. The illuminance sensor setting device according to claim 2 , wherein
the illuminance sensor comprises a sensor switch to turn on or off an illuminance detection function of the illuminance sensor, and
the setter has an operation switch to turn on or off the illuminance detection function of the illuminance sensor.
7. The illuminance sensor setting device according to claim 6 , wherein
when one of the sensor switch and the operation switch is pressed and held, switching of the illuminance detection function by the pressing and holding is held in a priority state, so that after the switching, even if the other one of the sensor switch and the operation switch is normally pressed, the state of the illuminance detection function is not switched.
8. The illuminance sensor setting device according to claim 1 , wherein
the illuminance sensor comprises a plurality of the illuminance sensors, and
the setter is configured to set illuminance sensor addresses of the plurality of illuminance sensors.
9. The illuminance sensor setting device according to claim 8 , wherein
each of the plurality of illuminance sensors comprises a sensor switch to turn on or off an illuminance detection function of the illuminance sensor, and
the setter has an operation switch to turn on or off the illuminance detection function of each of the plurality of illuminance sensors.
10. The illuminance sensor setting device according to claim 9 , wherein
when one of the sensor switch and the operation switch is pressed and held, switching of the illuminance detection function by the pressing and holding is held in a priority state, so that after the switching, even if the other one of the sensor switch and the operation switch is normally pressed, the state of the illuminance detection function is not switched.
11. The illuminance sensor setting device according to claim 1 , wherein
the illuminance sensor comprises a sensor switch to turn on or off an illuminance detection function of the illuminance sensor, and
the setter has an operation switch to turn on or off the illuminance detection function of each of the plurality of illuminance sensors.
12. The illuminance sensor setting device according to claim 11 , wherein
when one of the sensor switching switch and the operation switch is pressed and held, switching of the illuminance detection function by the pressing and holding is held in a priority state, so that after the switching, even if the other one of the sensor switch and the operation switch is normally pressed, the state of the illuminance detection function is not switched.
