Light source device

Abstract

To provide a light source device in which multiple light-emitting elements light up individually and have two or more light distribution patterns. [Solution] In one embodiment of the present invention, a light source device is provided comprising: a light-emitting unit assembly comprising: a first light-emitting unit having a first light-emitting unit; a second light-emitting unit having a plurality of second light-emitting units, which are spaced apart along the outer circumference of the first light-emitting unit in a plan view and have a plurality of second light-emitting units; and a lens disposed on the light-emitting unit assembly, wherein the first light-emitting unit and the plurality of second light-emitting units are arranged vertically and horizontally, the first light-emitting unit and the plurality of second light-emitting units can each be independently controlled to light up, and the full angle of half maximum of the light distribution of the light emitted from the first light-emitting unit and emitted from the lens is different from the full angle of half maximum of the light distribution of the light emitted from the second light-emitting unit and emitted from the lens.
