摘要:
The invention relates to a lighting device (10) with a light emitter (1) that comprises OLEDs of at least two different primary colors. The light emitter (1) is followed by a primary optics, e.g. a collimator (13) or a lens, and by a tapered tubular reflector (14) with a diameter (d) that increases from its narrow end to its wide end. The light emitter (1) may particularly be composed of concentric rings of different OLEDs.
