Patent ID: 7762700

Claim:
An automotive rear combination lamp ( 10 ), comprising: a concave reflector ( 13 ) for receiving diverging light ( 12 ) from a plurality of light emitting diodes ( 44 , 144 ), and for reflecting a collimated beam ( 14 ) in a beam exiting direction; a largely planar structure ( 31 , 131 ) for mechanically supporting the light emitting diodes ( 44 , 144 ), for electrically powering the light emitting diodes ( 44 , 144 ), and for removing heat from the light emitting diodes ( 44 , 144 ), the largely planar structure ( 31 , 131 ) comprising: a printed circuit board ( 41 ); and a thermally conductive layer ( 43 , 143 ) parallel to and adjacent to the printed circuit board ( 41 ); and a housing ( 21 ) for mechanically supporting the largely planar structure ( 31 , 131 ), the housing ( 21 ) being in thermal contact with the thermally conductive layer ( 43 , 143 ); wherein the largely planar structure ( 31 , 131 ) is insertable in the beam exiting direction through an aperture in the concave reflector ( 13 ); wherein when the largely planar structure ( 31 , 131 ) is fully inserted into the aperture in the concave reflector ( 13 ), the plurality of light emitting diodes ( 44 , 144 ) are located at a focus of the concave reflector ( 13 ); and wherein when the largely planar structure ( 31 , 131 ) is fully inserted into the aperture in the concave reflector ( 13 ), the housing ( 21 ) remains largely outside the concave reflector ( 13 ).
