Abstract
An outdoor lighting fixture using LEDs as a light source has a decorative housing that includes a cast metal dome roof and one or more LED light engines, wherein the light engines conductive metal substrate is in conformal contact with a portion of the inner surface of the roof, such that the roof provides increased heat sink mass and the outer surface of the roof provides a heat dissipative surface area outside of the housing. Preferred embodiments include a street light wherein two LED light engines are mounted at about 20 and 160 degrees to a line parallel to the street segment to produce an asymmetric light profile that reaches over and along the street for an effective distance, but does not extend very far on the side away from the street. Also disclosed is a reflector module for an LED light engine having rows of cone reflectors modified to produce an effective emission pattern.
