Abstract (en)
[origin: WO2010108982A1] The invention relates to an operating unit (1) for operating at least one LED (9). Said unit has an electronic control system (2) for adapting a supply current to the operating characteristics of the LED or LEDs and a control unit (3) for controlling the LED operation. The invention is characterised in that the operating unit limits the maximum output of the LED or LEDs in a first operating phase to a predetermined level and the operating unit converts an external dim command in an appropriate manner.
