ILLUMINATION SYSTEM

摘要

An illumination system comprising at least two light sources arranged closely together and each emitting a unique light spectrum during operation, and an optical system (1). The optical system comprises an optical waveguide (4) with a coupling-in face (6) and a coupling-out face (7). The optical system further comprises a mirroring transition part (8) connecting the coupling-out face of the optical waveguide to a transparent light extraction panel (9). The transparent light extraction panel has an extraction structure (11) for coupling out light to the exterior. The optical waveguide and the extraction means are specularly reflecting, the mirror preferably being substantially specularly reflecting. Compared with the known illumination systems, the illumination system of the invention is relatively efficient and has an improved control of the light beam.
