SENSOR DEVICE, ILLUMINATION DEVICE, ILLUMINATION CONTROLLER, AND ILLUMINATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To control the lighting state of the light sources of a plurality of illumination devices on the basis of information detected with a plurality of sensors, without use of a complicated communication circuit.SOLUTION: A switching circuit S1 (switching element) is turned on when a human sensor 13 (sensor) is actuated. An inter-sensor connection terminal 11 (a first connection terminal) and an inter-sensor connection terminal 12 (a second connection terminal) are electrically inter-connected via the switching circuit S1. The two inter-sensor connection terminals 11 and 12 are electrically connected to other devices (e.g., a sensor device and a sensor circuit of a sensor-equipped illumination device). A signal output circuit 15 outputs a sensor actuation signal when the potential difference between the two inter-sensor connection terminals 11 and 12 between is smaller than a predetermined threshold. A control circuit 24 controls the lighting state of a light source 82 on the basis of the sensor actuation signal output from the signal output circuit 15.
