Flat lamp i.e. LED flat lamp, for use in mechanical engineering applications, has reflector arranged on lighting unit such that light of LEDs at portion of circuit board is bundled, so that regions are formed with different light intensity

摘要

The lamp has a lighting unit (10) comprising a set of LEDs (12) that are arranged on a circuit board. A plate-shaped optical reflector comprises recesses that function as light passage openings (30). The reflector is arranged on the lighting unit such that light (L1) of the LEDs at a predetermined surface portion of the circuit board is bundled, and unbundled light of the LED does not lie in the predetermined surface portion, so that two regions are formed with different light intensity. The reflector is arranged at different predetermined positions of the lighting unit by holes.
