Abstract
A compact optical assembly includes a linear array of LEDs, a plurality of reflectors, a plurality of lenses, and a cover. The reflectors include two reflecting surfaces that surround the LED light sources. One of the reflecting surfaces is defined by an arc of an ellipse that narrows into a throat in the axial direction away from the LED light source and cooperates with the other reflecting surface and the lens to create a collimated beam of light.
