Abstract (en)

[origin: WO2011083117A2] The invention relates to a method for operating at least one illuminant, in particular a light-emitting diode (LED) (23) of an LED module (4, 5), in which the light-emitting diode (23) is operated by a pulse-modulated current (I4, I5), wherein the deactivation duration (T2) of the pulse-modulated current (I4, I5) can be controlled by an external dimming command, and the amplitude (I0, 4, I0, 5) of the pulse-modulated current can be set depending on a calibration.
