Abstract: An LED module includes a light-emitting unit composed of a plurality of LEDs connected in series to one another, a sensor unit, a power interrupt circuit inserted into a power supply path through which the light-emitting unit is supplied with power from an external power source, and a control circuit that controls the power interrupt circuit according to output of the sensor unit. The LED module further includes a secondary battery and a voltage supply circuit. The voltage supply circuit supplies the control circuit with voltage equivalent to voltage drop between the ends of a group of LEDs included in the plurality of LEDs that constitute the light-emitting unit while the external power source is supplying power to the light-emitting unit, and supplies the control circuit with voltage output from the secondary battery while power interrupt circuit is interrupting the power from the external power source to the light-emitting unit.

Abstract: A lighting device includes a pyroelectric sensor, a shutter and a lighting control unit. The lighting control unit is configured, when the lighting load is turned off, to turn the lighting load on if the pyroelectric sensor detects a change in infrared radiation. The lighting control unit is also configured, when the lighting load is turned on, to turn the lighting load off if a repetition count or time of a lighting retention time reaches a specified count or time, respectively, with no change in infrared radiation detected through the pyroelectric sensor within each lighting retention time per the passage of lighting retention time.
