摘要：
A spotlight is provided with a substrate having LEDs disposed thereon and a main body casing on which the substrate is provided. The main body casing has a rear side portion having thermal conductivity, which is thermally coupled to the substrate, and is capable of changing the irradiation angle of light emitted from the LEDs. A plurality of heat-radiating fins for forming grooves operating as a plurality of convection paths along the direction of changing the irradiation angle are provided on the rear side portion of the main body casing.
