PURPOSE: A light illuminating apparatus is provided to improve the efficiency of a heat emitting operation by forming concave-convex parts to be expanded along the longitudinal direction of a light source part. CONSTITUTION: A reflector(20) is installed inside a housing(10). A light source part(30) is supported by the housing and emits light toward the reflector. The light source part includes a body(32), a light emitting groove, and a plurality of light emitting diodes(31). The light emitting groove is installed at the inclined surface of the body. The light emitting diodes are installed inside the light emitting groove. Concave-convex parts are formed at the lower side of the body. |
