摘要： A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).

摘要： 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.
