Patent ID: 7781787

Claim:
A light emitting diode (LED), comprising: a light emitting element mounted on a power source supply means and having a wide light distribution characteristic; and a sealing means of a transparent material to seal the light emitting element, wherein the sealing means comprises: an upper reflection surface having a reflection mirror that reflects light emitted from the light emitting element in a direction orthogonal to a center axis of the light emitting element; a side radiation surface that sideward radiates light reflected by the upper reflection surface; and a central radiation surface placed at a center of the upper reflection surface, in which an increment of solid angle of the central radiation surface directly externally radiates light emitted from the light emitting element via the reflection mirror in a direction nearly parallel to the center axis, wherein the central radiation surface has a shortest distance from the light emitting element of less than ½ a radius R of the upper reflection surface to form a proximity optical system, and wherein an upper surface of the central radiation surface is exposed to an outside of the light emitting diode.
