Light-emitting diode, led light, and light apparatus

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 in a direction nearly parallel to the center axis,
• wherein the upper reflection surface is formed such that its radius R is greater than a height H from an emission surface of the light emitting element to an edge of the upper reflection surface in the center axis direction of the light emitting element so as 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.

• 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 a 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 sealing means extends up to an edge of the upper reflection surface located on an intersection of the side radiation surface with the upper reflection surface, and
• wherein an upper surface of the central radiation surface is exposed to an outside of the light emitting diode.
