Abstract:
It is provided a LED light (10) for a motor vehicle, comprising several LED fields (14), wherein each LED field (14) comprises at least one LED (L1, L2, L3, L4), a housing (34) for supporting the LED fields (14) and a circuit board (12) comprising a driving electronics for operating the LED fields (14), wherein the LED fields (14) are connected in series by the driving electronics and the driving electronics is adapted to switch on and off each LED field (14) according to its position in the series in dependence of a signal, wherein the circuit board (12) is connectable to an outside of the LED light (10) located current source (16) for applying an electrical current to the LED fields (14), and wherein the circuit board (12) is integrated into the housing (34). Since complicated and/or changing switching orders of the LED fields (14) are not intended the necessary circuit board (12) for providing the corresponding driving electronics may be so small that it may be integrated into the housing (34) of the LED light (10) without significantly increasing the building space. Particularly a lot of wires between a central control unit and the different LED fields (14) are omitted as well as the central control unit itself so that the LED light (10) only requires a small building space.
