Abstract
This invention improves the use efficiency of light emitted by a solid light emitter such as a light emitting diode, and realizes a desired directional pattern. On a front boundary surface of a mold resinsealing a light emitter, there are formed a direct emission regionfor emitting the light from the light emitterand a total reflection regionfor totally reflecting the light from the light emitter. The direct emission regionis convex lens-shaped. A light reflecting portionhaving a concave mirror shape is disposed on a rear wall of the mold resin. A part of light emitted from the light emitteris emitted forward by receiving an optical lens action when it passes through the direct emission region. Another part of the light emitted by from the light emitteris totally reflected by the total reflection region, and is reflected by the light reflecting portion, and emitted forward from the total reflection region
