LED lighting assembly with improved heat management
First Claim
1. A light emitting diode assembly comprising:
- at least one light emitting diode;
a mounting die, said mounting die having a front wall with a top surface, a bottom surface, a side wall extending rearwardly from said bottom surface, said bottom surface and said side wall cooperating to form a cavity therein and an aperture in said front wall extending from said top surface into said cavity;
a first circuit board having a top surface and a bottom surface that is received adjacent said top surface of said front wall of said mounting die,a second circuit board fully contained within said cavity, said first circuit board, said second circuit board and said at least one light emitting diode are in electrical communication with one another,wherein said light emitting diode is affixed to said top surface of said first circuit board.

Abstract
The present invention provides a lighting head assembly that incorporates a high intensity LED package into an integral assembly including a heat sink and circuit board for further incorporation into other useful lighting devices. The present invention primarily includes a heat sink member that also serves as a mounting die and a reflector cup into which the LED package is mounted. The circuit board is placed behind the reflector cup and includes riser members that extend through holes in the rear wall of the reflector cup to facilitate electrical connections to the leads of the LED. This particular means for assembly allows the reflector cup and circuit board to 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.
