Replaceable vehicle lamp with LED light sources
An LED light source ( 10 ) has a substantially planar housing ( 12 ) transversely arrayed about a longitudinal axis ( 14 ) and including a through-hole ( 16 ) in a first surface ( 17 ) thereof. A planar, heat conductive support ( 18 ) is positioned with the housing, the planar heat conductive support ( 18 ) having a front side ( 20 ), a back side ( 22 ) and a center point ( 24 ) coaxial with said longitudinal axis ( 14 ). LEDs ( 26 ) are mounted on the front side ( 20 ) and are arrayed about the center point ( 24 ). A base ( 28 ) supports the planar, heat conductive support ( 18 ) and is fixed to the housing ( 12 ). A heat sink ( 30 ) is in thermal contact with the base ( 28 ) and extends outwardly of the housing ( 12 ). A connector ( 32 ) is formed with the housing ( 12 ) for receiving electrical input to the LEDs.
