LED lighting assembly
First Claim
1. A light emitting diode assembly comprising:
- a light emitting diode having a front luminescent portion and a mounting base, said mounting base having a heat transfer plate on a rear surface thereof and a first and second contact lead extending from the sides thereof;
a mounting die, said mounting die being thermally conductive, said mounting die having a rear surface, said mounting die having a recess in said rear surface thereof and an aperture extending there through, said recess being configured to receive said mounting base of said light emitting diode, wherein said luminescent portion of said light emitting diode extends through said aperture; and
a spreader plate, said spreader plate being thermally conductive, said spreader plate in thermal communication with said heat transfer plate of said light emitting diode and said rear surface of said mounting die, wherein said spreader plate conducts heat from said light emitting diode to said mounting die.

Abstract
The present invention provides a lighting head assembly that incorporates a high intensity LED package into an integral housing for further incorporation into other useful lighting devices. The present invention primarily includes two housing components, namely an inner mounting die and an outer enclosure. The inner and outer components cooperate to retain the LED package, provide electrical and control connections, provide integral heat sink capacity and includes an integrated reflector cup. In this manner, high intensity LED packages can be incorporated into lighting assemblies through the use of the present invention by simply installing the present invention into a housing and providing power connections thereto.
