  • Method for dimming a light-emitting diode arrangement of a motor vehicle
    Patent number: 8669714
    Abstract: The invention concerns a process to dim a light emitting diode device of a motor vehicle. In order to keep changes of the light intensity from being noticeable, they must be appropriately small. Electronic dimmers with pulse width modulation have historically required a microcontroller with a pulse width modulation generator with at least 10 bits. In order to use cheaper controllers, the invention proposes that the pulse width signal be modulated as a function of a variable on-period and a simultaneously variable period length.
