Abstract (en)
[origin: WO2007041877A1] The invention relates to a light source (20) comprising, in addition to at least one light-emitting semiconductor chip (21) as light generating element which is at least partly surrounded by an at least partly transparent material (26), a reflector arrangement with the following properties: light radiating and not absorbed into the environment from the boundary surface (23) between the at least partly transparent material and an environmental medium largely impinges on the reflector arrangement and light coming to the reflector arrangement from said boundary region is largely reflected in the direction of the boundary surface.
