Abstract
An assembly for high-powered LEDs provides a direct attachment of the LED to a ceramic thermal conductor/electrical insulator sealed in a housing with a compression element between a portion of the housing and ceramic heat sink to provide a predetermined range of biasing force locating the ceramic heat sink against the portion of the housing with dimensional changes in the ceramic heat sink caused by thermal expansion of the ceramic heat sink.
