An edge-lit backlighting system for liquid crystal displays employs a number of light strips in the form of thin, light weight sections of a thermally conductive substrate each of which mounts a plurality of light engines having an array of densely packed, primary color light emitting diodes, which, when collectively illuminated, produce a white light of desired reference white chromaticity.

An apparatus for housing and cooling circuit card assemblies employed in communication and other systems is disclosed including a chassis having opposed end walls which are formed with a series of spaced inlet card guides and correspondingly spaced outlet card guides, respectively. A straight-pass heat exchanger is directly mounted to each circuit card assembly via thermally conductive material, and opposed ends of the heat exchanger are mounted by a wedge lock to respective inlet and outlet card guides. The heat exchanger employs unique angled interface geometry that creates a gasketless airtight joint with complimentary inlet and outlet card guide geometry through which cooling air passes.
