Abstract (en)
[origin: EP1648204A1] The vehicle lighting device has at least one light emitting diode (3) and a light control device (1) connected to the diode. The control device generates a pulse width modulated clock pulse signal which is conveyed to the diode. A circuit (2) is arranged between the control device and the diode. This is used to convey the pulse wdith modulated clock pulse signal to the diode over different resistances in dependence on a control signal. Independent claims also cover a control method.
