## Abstract

A light emitting diode module is removably coupled to a heat sink with screws and includes slots configured to receive at least a portion of the screw therethrough, the width of the slot being greater than the thread-width of the screw but less than the width of the screw head. Some slots also include a keyhole having a diameter greater than the width of the screw head. For embodiments without keyholes, the module is coupled to a heat sink by loosening the screws, sliding them into the slots, and tightening the screws to hold the LED module in place. For embodiments with one or more keyholes, the keyhole is vertically aligned with the screw, the module is moved down over the screw, and the screw is moved into the narrower portion of the slot. Then, the screws are tightened to hold the module in place against the heat sink.
