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 ).
