Abstract:
Embodiments include an automotive LED lighting module comprising an LED lamp comprising a number of light-emitting diodes; a first driver module configured to drive the LED lamp at a first DC voltage level (U_hi); a second driver module configured to drive the LED lamp at a second DC voltage level (U_lo), which second DC voltage level (U_lo) is lower than the first DC voltage level (U_hi); and a switch arrangement comprising an interface for connection to a two-level DC voltage supply (PS), and wherein the switch arrangement is configured to connect the first driver module to the LED lamp when the input voltage is at a first level and to connect the second driver module to the LED lamp when the input voltage level is at a second level (U_lo). Embodiments can further include an automotive lighting system of a vehicle, and a method of operating an automotive LED lighting system.
