    摘要: The present invention provides a light collimating structure (102) comprising a first collimator (131) collimating light of a first property and at least one second collimator (141) collimating light of a second property, where the receiving areas (132, 142) of the collimators at least partly overlap and where the output areas (133, 143) of the collimators partly overlap. The at least two collimators act essentially independently from each other. Hence, the collimators can be positioned independently from each other, in order to provide good collimation for each of the light sources of the lighting unit. Further, the collimators may be designed independently from each other such that a good light mixing is obtained.

    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.
