    摘要: The present invention relates to lighting device (10). The lighting device comprises a light guide plate (12), and at least one array of light emitting diodes (LEDs) (14), which LEDs are accommodated in holes arranged in the light guide plate, wherein each hole has: at least two side facets (18) through which light from the LEDs is to be laterally coupled into the light guide plate, and at least one corner (20) formed by two converging side facets of the at least two side facets. This promotes TIR at adjacent light sources and therefore diminishes losses due to absorption or scattering at adjacent holes.

    摘要: The illumination system has an array of light sources (1, 1′, . . . ) such as an array of light emitting diodes arranged in a pre-determined manner in a first plane (11), wherein dsource is a characteristic dimension of the spatial arrangement of the light sources in the first plane. An array of associated lenses (2, 2′, . . . ) is arranged in substantially the same pre-determined manner in a second plane (12). Each lens has substantially the same focal distance flens. The array of lenses is provided at a plane distance dplane from the array of light sources. The plane distance dplane is substantially equal to the focal distance flens of the lenses. The illumination system has displacement means for displacing the array of lenses with respect to the array of light sources so as to obtain a plurality of directional light beams projecting spots on a projection plane arranged at a projection distance dprojection from the illumination system, wherein dprojection≧10×dsource and dprojection≧10×dplane.

    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.
