Abstract:
An LED lamp A1 includes a plurality of LED modules 20, and a controller 40 for switching the LED modules 20 between a light-emission state and a non-light-emission state. The controller 40 performs control to bring only part of the LED modules 20 into the light-emission state. This arrangement allows illumination in a particular direction with less electric power.
