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 resin 13
sealing a light emitter 12, there are formed a direct emission region 18
for emitting the light from the light emitter 12 and a total reflection
region 19 for totally reflecting the light from the light emitter 12. The
direct emission region 18 is convex lens-shaped. A light reflecting
portion 20 having a concave mirror shape is disposed on a rear wall of
the mold resin 13. A part of light emitted from the light emitter 12 is
emitted forward by receiving an optical lens action when it passes
through the direct emission region 18. Another part of the light emitted
by from the light emitter 12 is totally reflected by the total reflection
region 19, and is reflected by the light reflecting portion 20, and
emitted forward from the total reflection region 19.
