    Abstract: An electric headlamp has a thermally conductive backplate with a support board positioned thereon. The support board has a first and a second side, and board registration areas for locating the support board. The board has registration areas formed on the backplate that cooperate with depressions formed in the second side of the support board. An array of LEDs is mounted on the first side of the support board, the LEDs pointing normal to the support board. Electrical circuitry is formed on the support board to supply power to the LEDs. A lens is associated with each LED, each lens having an input surface to receive light emitted by the respective LED, and an output surface to direct light from the LEDs in a preferred pattern. A cover encloses the respective LEDs and lenses and circumferentially seals to the backplate. The cover can be provided with a lens.
