ILLUMINATION SYSTEM

摘要

An illumination system has a plurality of light emitters (R, G, B), at least one light-collimating section ( 12, 12', 12 '') for collimating the light emitted by the light emitters arranged along a longitudinal axis ( 25 ) of the illumination system. The at least one lightcollimating sections merge into a light-mixing section ( 3 ) at a side facing away from the light emitters. The light-mixing section has a plurality of side-faces parallel to the longitudinal axis. A surface of the light-mixing section facing away from the light emitters is provided with a light-shaping diffuser ( 17 ). Preferably, the light-shaping diffuser is a holographic diffuser. Preferably, the illumination system comprises a plurality of light-collimating sections each of the light-collimating sections being associated with at least one light emitter. The illumination system provides improved spatial and spatio-angular mixing of the light emitted by the light emitters.
