Abstract (en)
[origin: WO2008031405A1] Known is a reflector lamp with a combined reflector of a revolution-ellipsoid section and a further concave mirror with aperture. Its centre coincides with the first focal point and the aperture's centre coincides with the second focal point of the ellipsoid of revolution; the light source is arranged in the first focal point. This design type with a singular light source requires a high-power lamp. In the new reflector emitter, for a strong light beam using a plurality of lower-power lamps, revolution-ellipsoid sections RE are formed from revolution ellipsoids which are additionally cut in the focal-point plane. The sectional planes of all the mirrors are arranged in one common base plane and the mirror surface of the further concave mirror WH is directed in the direction opposite the others. The light sources LQ are arranged in the first focal points of the revolution-ellipsoid sections RE and their second focal points and the focal point of the further concave mirror WH coincide. All the light beams which are incident on the surface of the revolution-ellipsoid sections RE are reflected onto the further concave mirror WH. Here, the light beams form a shaped bundle which leaves the reflector emitter at right angles to the base plane through the aperture RA.
