ABSTRACT:
A lighting device with a light emitter includes OLEDs of at least two different primary colors. The light emitter is followed by a primary optics, e.g. a collimator or a lens, and a tapered tubular reflector with a diameter that increases from its narrow end to its wide end. The light emitter may include concentric rings of different OLEDs.
