Light emitting diode

A light-emitting diode comprising:

• a light-emitting element;
• a lead assembly for supplying electric power to said light-emitting element;
• a reflection mirror provided in an opposing relation to the light-emitting surface of said light-emitting element;
• and
• a radiation surface for radiating light reflected on said reflection mirror to the outside,
• wherein said reflection mirror is a metal mirror which is obtained by combining a plurality of metal portions to give the assembly a concave shape, or which is obtained by mirror-surface-treating the concave surface of said metal mirror.

A light-emitting diode comprising:

• a light-emitting element;
• and
• a concave reflection mirror provided in an opposing relation to the light-emitting surface of said light-emitting element, light emitted by said light-emitting element being reflected on said reflection mirror, to be radiated to the outside,
• wherein said reflection mirror is a metal mirror which is obtained by processing a metal plate to give it a concave shape, and said reflection mirror has a linear reflectance of 65% or higher.

A light-emitting diode comprising:

• a light-emitting element;
• a lead assembly having a mount for mounting said light-emitting element;
• and
• a metal reflection mirror provided in an opposing relation to the light-emitting surface of said light-emitting element, light emitted by said light-emitting element being reflected on said reflection mirror, to be radiated to the outside,
• wherein said mount has a recess whose mouth opens towards said reflection mirror with the center of the mouth being in alignment with the central axis of the reflection mirror, and the recess contains said light-emitting element, and a fluorescent material which converts the light emitted by said light-emitting element to light of a different wavelength.
