Patent ID: 7300183

Claim:
A light emission source comprising: a reflecting member; a resin layer disposed in proximity of a light reflecting surface of the reflecting member; and a light-emitting element to emit light rays toward the resin layer, wherein a light-outgoing surface of the resin layer has a direct light-outgoing region and total reflection region, wherein the direct light-outgoing region passes light rays emitted from the light-emitting element therethrough so as to emerge out of the resin layer, wherein the total reflection region reflects the light rays emitted from the light emitting element so as to be directed to the reflecting member and passes the light rays reflected by the reflecting member therethrough so as to emerge out of the resin layer, and wherein dimensions of the total reflecting region is larger than that of the direct light-outgoing region, wherein a portion of a boundary between the total reflection region and the direct light-outgoing region is inclined in a direction opposite to a direction that the light rays emerge with respect to a plane perpendicular to an optical axis of the light-emitting element.
