Abstract: A universal load control module may include a power supply that operates over a wide voltage range, a microcontroller, and one or more functional control blocks. A functional control block may include a dimmer circuit for controlling a lighting load that provides reverse phase cut mode dimming, forward phase cut mode dimming, and hybrid phase cut mode dimming, as well as thermal protection. One or more universal control modules may be housed in a cabinet that include a cabinet control module. The cabinet may include additional thermal protection measures.

Abstract: Embodiments of this invention provide an enclosure for an LED circuit board. The enclosure is manufactured from a flame resistant material and includes LED apertures through which LEDs mounted on an LED circuit board may pass. The enclosure is designed to be positioned on the LED circuit board so that, when so positioned, the LEDs extend at least partially through the LED apertures in the enclosure. When the enclosure is positioned on the board, portions of its lower surface contact the upper surface of the board. Various fixation/retention methods may be used to retain the enclosure in position relative to the circuit board. It is preferable that such methods allow for the separation of the enclosure from the board.
