    摘要: A waveguide (40; 51; 61), arranged to guide light from at least one light source (53a-c), the waveguide comprising at least one guiding edge (43; 50a-c; 60) adapted to contain the light in the waveguide (40; 51; 61), and an extraction edge (44; 50d) adapted to enable extraction of the light from the waveguide (40; 51; 61), wherein the guiding edge (43; 50a-c; 60) is configured to reflect the light on its way towards the extraction edge (44; 50d). The guiding edge (43; 50a-c; 60) is further configured such that a direction (xr1, Xr2) of reflection of a ray of light impinging on the guiding edge (43; 50a-c; 60), in a given direction (xi) of incidence relative to a general direction (X0) of extension of the guiding edge (43; 50a-c; 60), is dependent on a position (P1, P2) of incidence along the guiding edge (43; 50a-c; 60). The waveguide may be configured such that virtually no light is lost through back-scattering or unintentional extraction or outcoupling through the at least one guiding edge.

    摘要: The present invention relates to a lighting system comprising a plurality of LEDs emitting light with different colors. The LEDs are provided with collimating optical components (51, 55) in order to emit collimated light beams. The LEDs are arranged in at least two layers (43, 45) and the collimating optical components (51) in the front layer are dichroic reflectors, so that they reflect the light from the associated front layer LED but transmit the light emitted from the rear layer behind. This eliminates or reduces the occurrence of colored edges around shadows on an illuminated surface.
