Adjustment device for moving rotor, of headlight, has limiting unit and stator and/or rotor of stepper motor positioned relative to each other such that rotor is displaced around given displacement value opposite to discrete position

摘要

The device (15) has a stepper motor (25) for moving a rotor (35) into different discrete positions, and a limiting unit for limiting a movement area of the rotor, where a reference position of the rotor limits the movement area of the rotor. The limiting unit and a stator (27) and/or the rotor of the stepper motor are positioned relative to each other such that the rotor is displaced around a given displacement value opposite to one of the discrete positions with respect to the movement area in the reference position. An independent claim is also included for a motor vehicle lighting device, comprising a LED.
