Lamp with rotor

摘要

The lamp has a light source (1) i.e. LED, and a light emitting surface (5) for discharging light from the light source to an area outside of the lamp. A rotor (4) is designed as an optical element that is formed in such a manner that the optical element optically influences the light from the light on the path to the light emitting surface. The rotor partially reflects the light from the light source, and a cylindrical cooling body (2) is thermally connected with the light source for cooling the light source. A rotor housing (6) comprises a reflective inner wall area.
