High power led electro-optic assembly
The present invention provides a high power LED electro-optic assembly ( 40 ) including conductive heat sink ( 18 ) and an LED ( 14 ) mounted at one end of the heat sink. The LED ( 14 ) is in electrical engagement with the heat sink ( 18 ). The assembly ( 40 ) also includes a reflector ( 2 ) mounted at the other end of the heat sink. An insulating bond material ( 19 ) is provided between the reflector and the sink. The assembly ( 40 ) further includes a conductive bonding pin ( 15 ) extending through the reflector ( 12 ) and is in conductive engagement therewith and an electrical engagement ( 16 ) which electrically engages the pin ( 15 ) to the LED ( 14 ). Finally, an electric sleeve assembly ( 30 ) where the sleeve ( 32 ) is coated with an electrical insulating coating ( 34 ) is applied to the LED electro-optic assembly.
