An LED light source ( 10 ) comprises a heat sink ( 12 ) having a body ( 14 ) with a front surface ( 16 ) and a rear surface ( 18 ), the rear surface ( 18 ) being provided with heat dissipaters ( 20 ). The front surface ( 16 ) includes a pocket ( 22 ) for the receipt of components ( 24 ), the components including at least one LEDs ( 25 ) and electrical circuitry therefor. A housing ( 26 ) has a flange ( 28 ) and a tubular projection ( 30 ) fitted into the pocket ( 22 ) in a manner to fix the components ( 24 ) in the heat sink ( 12 ); and an optical light guide ( 32 ) having at least one light pipes ( 34 ) is positioned in the tubular projection ( 30 ), each of the at least one light pipes ( 34 ) having a light input end (34a) fixed in light gathering alignment with the at least one LEDs ( 25 ) in a one-to-one relationship.
