Shaped Reflector with spatially separated foci for the illumination of identical areas, and method for determining its surface

摘要

Local adapted shapes on a reflector (1) are designed to give the reflector multiple focal points (10a,10b,110a,110b) separated by spaces. As a result, electromagnetic bundles (5a,5b,50a,50b) of rays emerging from rays (4a,4b,40a,40b) separated by spaces are directed at a common illuminating area (3a,3b), especially for bundles with different frequencies/bands that illuminate the reflector. ??An Independent claim is also included for a method for determining the shaping of a reflector's surface.
