Abstract:
An LED array and driver design minimizes space requirements and simplifies assembly, while reducing costs. A printed circuit board with LED driver electronics has a central opening through which the LED array is mounted. In one form the LED array is a chip on board (COB) array, the array being circular and fitting closely within the central opening of the PCB. Four integral leaf springs are formed into the flat PCB, in position to push the LED array down when the PCB and LED array are attached against the heat sink. Two of the springs have electrical contacts that make contact with those of the LED array. With the LED array and driver circuit on the face of a light assembly, the space rear of the driver circuit is free to be open to air flow for cooling.

Claim (Index 1):
In an LED light assembly, an LED array mounted in a space efficient manner against a heat sink, the assembly comprising:\n an LED array on a heat conducting substrate, a printed circuit board (PCB) with a central opening sized to receive the LED array, the PCB having pairs of slits extending generally radially into the board from the central opening, so as to form a plurality of cantilevered spring arms in the board, some of the spring arms including PCB electrical contacts positioned to press down against the LED's heat conducting substrate when the LED array is assembled against the back side of the printed circuit board, and the heat conducting substrate of the LED array having mating LED electrical contacts in position to be engaged with the PCB electrical contacts, a heat sink plate assembled behind the LED array such that a back side of the heat conducting substrate of the LED array is pressed against the heat sink plate, and the printed circuit board being secured to the heat sink plate by fasteners such that the spring arms are deflected and push down on the heat conducting substrate of the LED array, to make both electrical contact with the LED array and heat transfer contact of the LED heat conducting substrate with the heat sink plate, thereby providing a compact, efficient retention assembly for the LED array.
