Lighting device has semiconductor light source, reflector optically downstream semiconductor light source, and screen optically downstream reflector, where semiconductor light source is fastened to screen

摘要

The lighting device (11) has a semiconductor light source, a reflector (12) optically downstream the semiconductor light source, and a screen (15) optically downstream the reflector. The semiconductor light source is fastened to the screen. The screen is formed as a heat spreading body and has an optical edge. A rear side (16) of the screen is arranged on a part of a light emitting opening of the reflector.
