Abstract: A connector for use in coupling a load device to electrical conductors of a direct current bus bar. The connector has a housing and the housing carrying a printed circuit board that is electrically coupled to the bus bar and the load device. The printed circuit board functions to control the providing of direct current power from the bus bar to the load device, provide a dimming signal to the load device, and/or selectively provide direct current from a source of emergency power to the load device.

Abstract: A connector includes a main housing element for holding smart connector circuitry. A threaded nub extends from the main housing element and is sized to be received within a knock-out of a junction box. The threaded nub has a first opening and a second opening separated by a barrier for allowing respective ones of power wires and dimming wires, which are coupled to the smart connector circuitry, to be passed from the main housing element to the junction box.

Abstract: A heat sink assembly includes a printed wiring board, a metal case and a circuit package containing a gallium arsenide field effect transistor heat dissipating circuit. The circuit package includes a metal slug formed integrally with the circuit package, the heat dissipating circuit being bonded to an obverse surface of the metal slug. The printed wiring board includes first and second metal lands, the first metal land being disposed on an obverse surface of the printed wiring board, the second metal land being disposed on a reverse surface of the printed wiring board. A solder film is formed bonded to and thermally coupling a reverse surface of the metal slug to the first metal land, and a plurality of solder posts are formed, each post bonding to and thermally coupling the first metal land to the second metal land. The metal case is pressed against the second metal land with a grease film of thermally conductive grease squeezed therebetween.
