摘要

The tube light or housing of tube light (3) is covered partly with a semitransparent organic photodiode (4,5), which is connected at an evaluation unit (6). The organic photodiode represents a transmission of approximately 30 percent. The evaluation unit is connected at controlling or a regulating unit, which controls the intensity of the radiation delivered from the tube light.
