Abstract
On a front wall of a mold resin (13) sealing a light emitter (12), a direct emission region (18), through which the light emitted from the light emitter (12) directly passes to the outside, and a total reflection region (19), by which the light emitted from the light emitter (12) is totally reflected, are formed. The direct emission region (18) is formed into a shape of a convex lens. A light reflection portion (20) which is made of a concave mirror is provided on the rear face of the mold resin (13). When a part of the light emitted from the light emitter (12) passes through the direct emission region (18), it is affected by the lens to be emitted to the front direction. After another part of the light emitted from the light emitter (12) is totally reflected by the total reflection region (19), it is reflected by the light reflection portion (20) to be emitted to the front direction through the total reflection region (19).

29. 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. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)
