Light module
First Claim
1. An illumination system comprising:
- a receptacle with first and second contacts, the receptacle mounted on a heat sink that includes a top surface, wherein the receptacle has one of a ramp and a shoulder;
a light emitting diode (“
LED”
) assembly comprising a frame, a LED array supported by the frame, a heat spreader with an upper and a lower surface, the upper surface in thermal communication with the LED array and supported by the frame;
circuitry configured to receive an input voltage of not more than 24 volts and convert such input voltage into a desired DC voltage;
first and second terminals supported by the frame, the first and second terminals coupled to the circuitry so as to provide an input power source, the first and second terminals configured to respectively engage the first and second contacts; and
a cover rotatably coupled to the LED assembly, the cover having the other of the ramp and the shoulder, wherein, when the cover is rotated, the shoulder and ramp engage each other and cause the cover to translate vertically and the vertical translation of the cover causes the heat spreader to translate vertically, wherein the heat spreader is configured to translate vertically without rotation so that the heat spreader is thermally coupled to the top surface.

Abstract
An illumination module is provided that can be inserted into a receptacle with a ramp that includes a wall and may be mounted on a support surface, such as a heat sink, and the illumination module include a cover and an LED assembly rotateably coupled to the cover. The LED assembly seats within the receptacle which causes terminals of the LED assembly to align with contacts on the receptacle. Circuitry is provided in the module that accepts an input voltage and converts the input to a desired driving output. The cover can be rotated relative to the receptacle so as to engage ramps so as to direct the LED assembly into the receptacle. When the LED assembly is attached to the receptacle, the terminals on the LED assembly mate with the contacts on the receptacle.
