LAMP UNIT FOR AN ADAPTIVE FRONT LIGHTING SYSTEM FOR A VEHICLE
First Claim
1. A lamp unit (501) for an adaptive front lighting system (500) for a vehicle (100), comprising:
- a liquid crystal element (200/200′
) arranged to receive light emitted by a light source (502), which liquid crystal element (200/200′
) has a first state in which it is adapted to transmit incoming light without substantially refracting said incoming light, and a second state in which it is adapted to refract said incoming light when the light passes through said liquid crystal element (200/200′
), wherein the liquid crystal element is controlled in dependence on a signal received from the adaptive front lighting system (500).

Abstract
The present invention relates to a lamp unit (501) for an adaptive front lighting system (AFS) (500) for a vehicle (100). The lamp unit (501) comprises a liquid crystal element (200/200′) arranged to receive light emitted by a light source (502), which liquid crystal element (200/200′) has a first state in which it is adapted to transmit incoming light without substantially refracting said incoming light, and a second state in which it is adapted to refract said incoming light when the light passes through said liquid crystal element. This allows light to be altered without any mechanical movements in or of the lamp unit (501). The present invention also relates to an AFS (500) comprising such a lamp unit (501), and a vehicle (100) comprising such an AFS (500).
