Light emitting apparatus
First Claim
1. A light emitting apparatus, comprising:
- a light source section comprising a solid-state light emitting element;
a power supply section that supplies power to the light source section;
a reflection section that is disposed opposite to a light extraction surface of the light source section to reflect light emitted from the light source section; and
a heat radiation section that is disposed with a heat radiation width in a back direction of the light source section.

Abstract
A reflection-type light emitting apparatus has an excellent heat radiation property and allows the use of a high-power light emitting element, the minimization of a reduction in radiation efficiency of reflected light, and the focused radiation of high-output light at high efficiency. The apparatus has: a case 10 of metallic material and with an excellent heat radiation property; a reflection mirror section 11 formed fitted to the lower portion of case 10; a transparent plate 12 to cover the upper surface of case 10; heat radiation plates 13, 14 of metallic material with excellent heat conductivity and inserted inside the case 10; an LED element 2 mounted on the heat radiation plate 13; lead sections 15A, 15B fixed through an insulating layer 15a to the heat radiation plate 13 to serve as a power supply member to supply power to the LED element 2; and a spacer 16 of an insulating material to insulate the lead sections 15A, 15B from the case 10.
