Abstract:
An electrically driven light emitting diode (LED) assembly comprising;an electrically and thermally conductive heat dissipater (10), an electrically insulating layer (12) over said heat dissipater (10), circuit traces (14) disposed in predetermined spaced lengths over said layer (12) to prevent electrical conduction between said traces (14) and said heat dissipater (10), a plurality of light emitting diodes (LEDs) (20) each having at least one electrical lead (22) for electrical contact with said traces (14) for powering said LEDs (20), an independent holding device (24, 26, 28, 30 or 32) holding each of said LEDs (20) in a predetermined position on said insulating layer (12) with at least one of said electrical leads (22) thereof in electrical engagement with one of said traces (14), said device (24, 26, 28, 30 and 32) including a holding portion (34, 134) for engaging each of said LEDs (20) and a connecting portion (36, 136) connected to said heat dissipater (10) for reacting between each of said LEDs (20) and said heat dissipater (10) to urge said holding portion into engagement with each of said LEDs (20) to urge at least a portion of each of said LEDs (20) into thermal engagement with said heat dissipater (10).
