LED lamp for illumination of e.g. office room, has base surfaces whose curvature is adapted to curvature of area of carrier element, where base surfaces lie opposite to carrier element

摘要

The lamp has optical elements (1) including base surfaces (2) defined by a circular line (4) with two symmetrical axes aligned on each other. The optical elements are arranged in an optical path behind two LEDs (10). The base surfaces are turned towards light radiating ends of the LEDs. The base surfaces are formed as planar and curved if a carrier element is formed as planar and curved, respectively. A curvature of the base surfaces is adapted to a curvature of an area of the carrier element, where the base surfaces lie opposite to the carrier element.
