Abstract
A compact optical assembly includes a linear array of LEDs and a plurality of reflectors. The reflectors include two concentric reflecting surfaces that surround the LED light sources. The inner reflecting surface reflects the majority of the light emitted from the LED light source and the outer reflecting surface reflects light emitted through longitudinal channels in the inner reflecting surface. The concentric reflecting surfaces cooperate to create a wide-angle beam of light with a desired dispersion pattern.
