LED lighting assembly
DCFirst Claim
1. A light emitting diode assembly comprising:
- a prepackaged light emitting diode assembly including;
a front luminescent portion, anda mounting base, said mounting base having a heat transfer plate on a rear surface thereof and a first and second electrical contact leads extending from the sides thereof;
a mounting die, said mounting die being thermally conductive, said mounting die having a bottom surface and a side wail extending upwardly from said bottom surface, said bottom surface and said side wall cooperating to form a cavity therein, wherein said prepackaged light emitting diode assembly is received in said cavity with said heat transfer plate in thermal communication with said bottom surface of 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.
