ABSTRACT:
A device for coupling the light of multiple light sources (2, 3) that substantially consists of a reflectance surface (10, 11) for one or more of said light sources (2, 3) and at least one integration rod (14) having an incident surface (15), whereby the reflectance surfaces (10, 11) are positioned in light bundles (12) emitted by the light sources (2, 3) between said light sources (2, 3) and said integration rod (14); whereby the spot of each light source (2, 3) at its focal point has a surface that is smaller than the surface of said incident surface (15); and whereby said light bundles (12) enter the integration rod (14) at different parts of its incident surface (15).
