Abstract (en)
[origin: WO2013059849A1] What is proposed is: a method for dimming at least one light-emitting means (6), such as an LED or an OLED, for example, which is operated with a pulse-width-modulated current (i3, i4, i5), in which the duty factor and/or the amplitude of the pulse-width-modulated current (i3, i4, i5) is adjustable depending on a desired colour intensity or brightness of the light-emitting means (6), wherein, in order to adjust the colour intensity or brightness of the light-emitting means (6), at least one pulse of the pulse-width-modulated current is omitted or skipped.
