Abstract:
A support module (1), comprising a conducting layer (2) having a trough hole (5) and a receiving surface adapted to receive a solid state light source (3) with the electrical contact pad (4) being aligned with the through hole (5). The support module (1) further comprises an electrical insulation element (8) and at least one contact pin (9), extending through the electrical insulation element (8), and protruding through the through hole (5). Furthermore, the electrical insulation element (8) comprises a channel (10) allowing access to the end of the contact pin (9) and the electrical contact pad (4) of the solid state light source (3) received by the surface of the conducting layer (2). Such a channel makes it possible to reach the end of the contact pin and the contact pad through the insulation element with a soldering tool. Thus, it is possible to attach the solid state light source on a metal surface by soldering the contact pin to the contact pad. Mounting a solid state lighting device on a metal surface is advantageous in applications requiring good heat dissipation, since the heat dissipation properties of a metal surface is better than of a printed circuit board.
Abstract:
An apparatus electrically interconnects pins that project from the rear side of a backplane in separate arrays corresponding to respective circuit boards at the front side of the backplane. The apparatus comprises a connector board assembly extending across the rear side of the backplane between separate arrays of pins. The connector board assembly has signal routing circuitry that electrically interconnects those separate arrays of pins. This enables the respective printed circuit boards to be electrically interconnected independently of any signal routing circuitry within the structure of the backplane. Accordingly, the apparatus preferably includes a backplane that is free of signal routing circuitry for interconnecting pins that extend through the backplane.
