Patent ID: 8237188

Claim:
A light source comprising: an electrically insulating substrate having a first surface, a second surface located opposite the first surface and a plurality of side surfaces located perpendicularly to the first and second surfaces; at least one first electrically conductive layer affixed to and partially covering the first surface, the second surface and one of the side surfaces of the substrate; at least one second electrically conductive layer affixed to and partially covering the first surface, the second surface and one of the side surfaces of the substrate not covered by the first electrically conductive layer; a light emitter affixed to the first surface of the substrate in an area not covered by either of the at least one first electrically conductive layer or the at least one second electrically conductive layer, the light emitter comprising a first terminal and a second terminal; a first conductor connected to the first erminal and the at least one first electrically conductive layer; a second conductor connected to the second terminal and the at least one second electrically conductive layer; and a heat sink attached to the second surface of the substrate at a location in alignment with the light emitter on the opposite side of the substrate that is not covered by either the first or second conductive layer.
