Abstract:
A light-emitting device, comprising at least a first light source (101) and a second light source (102) is provided. The light source further comprises a first collimating means (111) for collimating light from the first light-source and a second collimating means (112) for collimating light from said second light source wherein the output areas of the collimating means at least partly overlaps. A light guiding means (107) is arranged between said light sources and said collimating means for guiding light from the first light source to the first light collimating means, and from the second light source to the second collimating means. A light-emitting device of the present invention can provide well mixed and collimated light even though there is a distance between the light sources and the collimating means.
