Abstract (en)
[origin: WO2011069176A1] The invention relates to a method for controlling an LED by means of a driver circuit, whereby a sensor device controls the luminosity in a contact-free manner by means of the driver circuit. Said contact-free control can take place by evaluating a capacitive coupling and the luminosity and the colour can be adjusted by the driver circuit depending on the capacitive coupling.
