Abstract: A sensor device according to an example of the embodiment is connected, on an input side rather than an illumination apparatus, to a main power source line of an illumination system to which a DC voltage is applied and to which the illumination apparatus is connected through a branch wire. The sensor device includes: a sensing unit that detects an object and outputs a detection signal; and a switch that is provided in the main power source line and connects or disconnects the main power source line by an on-off operation on the input side rather than the illumination apparatus. The switch is controlled to be turned on or off based on the detection signal of the sensing unit.

Abstract: A power supply includes an input for receiving a first DC voltage, an output for outputting a second DC voltage, a voltage conversion circuit configured to convert the first DC voltage into the second DC voltage, and a control circuit configured to control the voltage conversion circuit to vary a voltage value of the second DC voltage. The control circuit is configured to control the voltage conversion circuit so as to decrease the voltage value of the second DC voltage from a first voltage value to a second voltage value for a predetermined duration every time a predetermined period elapses. The first voltage value is equal to or greater than a voltage value necessary to keep lighting a light source. The second voltage value is smaller than the voltage value necessary to keep lighting the light source.

Abstract: A light emitting module includes a plurality of light source units having a rectangular plate shape and a base unit having an elongated rectangular plate shape. The light source units are disposed along a straight line and mounted to the base unit. The light emitting module further includes an optical cover configured to diffuse light emitted from the light source units. The optical cover has a rectangular shape when seen in a plan view and configured to cover the light source units. A length of each of sides of the optical cover and the light source units parallel to short sides of the base unit is substantially equal to a length of each of the short sides of the base unit.

Abstract: A control circuit is configured to, when switching a state of a light source from an extinguished state to a lighting state, control a voltage conversion circuit so that a second DC voltage has a voltage value which changes according to transmission data containing an activation command. A lighting device is configured to keep the state of the light source at the extinguished state until receiving the activation command from the receiver circuit, and to change the state of the light source to the lighting state when receiving the activation command from the receiver circuit.

Abstract: In a signal transmitter, a control circuit is configured to control a discharge switch and a control switch to transmit a transmission signal for causing the value of the output voltage to be a first voltage value or a second voltage value smaller than the first voltage value for each constant period. The control circuit controls the discharge switch and the control switch such that a voltage gradient becomes a prescribed gradient in a case where the control circuit changes the value of the output voltage from the first voltage value to the second voltage value.

Abstract: A receiver circuit is configured to receive a transmission signal represented by a change in DC voltage applied across power supply lines according to transmission data. The receiver circuit is also configured to compare the DC voltage (sampled value(s) of a detection voltage) with a threshold, thereby detecting a change in the DC voltage. The receiver circuit is further configured to calculate the threshold from a voltage value of the DC voltage (the sampled value(s) of a detection voltage) input to a receiver input unit.
