Abstract
A ceramic THS solder mounts a broad, regular field of LEDs and the electronics. To collect the lateral emissions, each LED seats on a thermal riser, at a focus of its primary mirror. If parabolic, the mirrors deliver collimated beams. If elliptical, each mirror focuses on a delivery FO, or on a phosphor dot placed inside the window or tipping the FO. The sealing window can integrate other lenses to complete this compact, self-cooled, hermetic light-emitting engine.
