Abstract
A light assembly is configured to produce a large area of light emission from an LED light source. The LED light source is mounted within a concave reflector and oriented to face the rear of the reflector. A compound reflecting surface diverts axial light from the LED away from the axis of the reflector to avoid blockage by the LED support structure. A peripheral reflecting surface redirects the diverted light. The LED light source may be a linear array of LEDs aligned with a linear focal axis of the reflector.
