## Abstract

The invention describes a lighting assembly for use in a lighting arrangement of a vehicle. The lighting assembly includes a projection lens and a light source array, wherein a center of the light source array and an optical axis of the projection lens have a lateral offset, and light sources of the light source array are individually controllable to adjust a swivel angle of a light beam generated by that lighting assembly. The invention further describes a controller for controlling the light sources of such a lighting assembly. The invention also describes a lighting arrangement for a vehicle, comprising such a lighting assembly and such a controller for controlling the light sources of the lighting assembly to adjust the swivel angle of the light beam. The invention also describes a method of generating a front beam for a vehicle comprising such a lighting assembly.

## Claims

### Claim 1

A lighting assembly for use in a lighting arrangement of a vehicle, comprising a projection lens and a light source array, wherein:
a center of the light source array and an optical axis of the projection lens have a lateral offset; and
light sources of the light source array are individually controllable to adjust a swivel angle of a light beam generated by that lighting assembly.

### Claim 2 (depends on 1)

The lighting assembly of claim 1, wherein the optical axis of the projection lens is arranged parallel to a longitudinal axis of the vehicle.

### Claim 3 (depends on 1)

The lighting assembly of claim 1, wherein the lighting assembly generates a front left beam and the center of the light source array is offset to the right of the optical axis of the projection lens.

### Claim 4 (depends on 1)

The lighting assembly according to claim 1, wherein the light source array is arranged essentially perpendicularly to the optical axis of the projection lens.

### Claim 5 (depends on 1)

The lighting assembly according to claim 1, wherein a light source of the light source array comprises an LED.

### Claim 6 (depends on 1)

A controller for controlling light sources of the light source array in the lighting assembly according to claim 1 to adjust the swivel angle of a light beam generated by that lighting assembly, the controller comprising a control signal generation unit for generating a control signal for selectively activating specific light sources of the lighting source array on the basis of the later offset between the center of the light source array and the optical axis of the projection lens.

### Claim 7 (depends on 6)

A lighting arrangement for a vehicle, comprising a lighting assembly for generating a light beam, and a controller according to claim 6 for controlling the light sources of the light source array to adjust the swivel angle of the light beam.

### Claim 8

A method of generating a front beam for a vehicle comprising a lighting assembly for generating the beam, wherein (1) a center of a light source array and an optical axis of a projection lens have a lateral offset and (2) the projection is positioned to receive and project light from each of the light sources in the array, the method comprising:
sensing an angle of turning of the vehicle; and
generating a control signal for the lighting assembly on the basis of the asymmetry displacement and on the basis of the angle of turning to selectively activate specific light sources of the light source array to adjust a swivel angle of the beam.

### Claim 9 (depends on 8)

The method of claim 8, wherein the optical axis of the projection lens is arranged parallel to a longitudinal axis of the vehicle.

### Claim 10 (depends on 8)

The method of claim 8, wherein the lighting assembly generates a front left beam and the center of the light source array is offset to the right of the optical axis of the projection lens.

### Claim 11 (depends on 8)

The method of claim 8, wherein the light source array is arranged essentially perpendicularly to the optical axis of the projection lens.

### Claim 12 (depends on 8)

The method of claim 8, wherein a light source of the light source array comprises an LED.
