Patent ID: 7815341

Claim:
An illumination apparatus, comprising: an elongate substrate; first and second electrically conductive rails, the first and second rails supported by the substrate so that the first and second rails are spaced apart and electrically insulated from one another; a plurality of LED modules, each module comprising a module body, an LED, and an electrical current path configured so that electrical current flows from a first electrical contact to a second electrical contact, the LED being interposed in the current path between the first and second contacts so that electrical current flows along the path and through the LED; and a plurality of pairs of fasteners adapted so that each of the plurality of LED modules is connected by a pair of fasteners to the elongate substrate so that the first and second contacts of each LED module are electrically connected to the first and second rails, respectively; wherein a first one of each pair of fasteners is adapted to engage the first rail and the first contact so as to conduct current between the first rail and the first contact.
