OPTICAL SEMICONDUCTOR LIGHT SOURCE AND LIGHTING APPARATUS FOR VEHICLE

摘要

Provided is an optical semiconductor light source that is equipped with: an optical-semiconductor mounting circuit board; a plurality of semiconductor light-emitting elements that are mounted on the optical-semiconductor mounting circuit board; and a reflector that is mounted on the optical-semiconductor mounting circuit board, and that surrounds the plurality of semiconductor light-emitting elements. The plurality of semiconductor light-emitting elements are arranged to be equally distanced from the reflector. The distances from the center of the space surrounded by the reflector to each of the plurality of semiconductor light-emitting elements are greater than the distance from each of the plurality of semiconductor light-emitting elements to the reflector.
