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.
