End stage for driving electromagnet of displacement device for changing vehicle headlamp functions has switching element as high-side element between supply voltage and electromagnet

摘要

The end stage (2) has a switching element (5) that applies a regulated magnet current to the electromagnet (1) and that is connected as a high-side element between a supply voltage (Ubat) and the electromagnet. The switching element is a semiconducting switching element, especially a switching transistor in the form of a FET, especially a MOSFET. Independent claims are also included for the following: a displacement device for changing vehicle headlamp functions, a motor vehicle headlamp that can be changed between various lighting functions and a method of changing a motor vehicle headlamp between various lighting functions.
