Method and switching for temperature regulation in a vehicle headlamp

摘要

The method involves determining power supply actually supplied to a headlamp interior space during operation of a headlamp. Actually possible power output is determined from a headlamp interior space comprising LED light sources, and power consumption is determined based on the determined power supply and the power output. Determination is made whether and which of heat regulation measures e.g. activation of a cooler and dimming of LED light sources, for the space are performed. Power supply parameters of the headlamp are measured for determining the power supply.
