## Abstract

Lighting device for a motor vehicle with a first plurality of selectively activatable light sources and a second plurality of light sources. The first and second pluralities of light sources being arranged on a common substrate and each light source of the first plurality being positioned at a distance from the other light sources of the first plurality of less than 1 mm. The lighting device includes an optical element having a first region positioned facing the first plurality of light sources and a second region positioned facing the second plurality of light sources, with the second region being provided with optical patterns.

## Claims

### Claim 1

A lighting device for a motor vehicle, comprising:
a first plurality of selectively activatable light sources,
a second plurality of light sources, with the first and second pluralities of light sources being arranged on a common substrate and each light source of the first plurality being positioned at a distance from the other light sources of the first plurality of less than 1 mm apart, and
an optical element having a first region positioned facing the first plurality of light sources and a second region positioned facing the second plurality of light sources, with the second region being provided with optical patterns

### Claim 2 (depends on 1)

The device as claimed in claim 1, wherein each light source of the first plurality of light sources has dimensions of less than 500 micrometers and in that the light sources of the first plurality of light sources are separated from each other by a distance of less than 1 millimeter.

### Claim 3 (depends on 1)

The device as claimed in claim 1, wherein each light source of the second plurality of light sources has dimensions of less than 500 micrometers.

### Claim 4 (depends on 1)

The device as claimed in claim 1, wherein the ratio between the distance separating two light sources of the second plurality of light sources and a dimension of each light source of the second plurality of light sources is greater than 2.

### Claim 5 (depends on 1)

The device as claimed in claim 1, wherein the common substrate is an active matrix substrate arranged to selectively control each of the light sources of the first plurality of light sources, with each of the light sources of the first plurality of light sources being mounted on and connected to the common substrate by means of a thin-film transistor integrated into the common substrate.

### Claim 6 (depends on 1)

The device as claimed in claim 1, wherein each optical pattern of the second region is arranged to receive the light rays emitted by one of the light sources of the second plurality of light sources and to concentrate these light rays along a given emission axis.

### Claim 7 (depends on 1)

The device according to claim 1, wherein that the first region is scattering.

### Claim 8 (depends on 1)

The device as claimed in claim 1, wherein the first region is coated with an anti-reflection coating.

### Claim 9 (depends on 1)

The lighting device as claimed in claim 1, further comprising a control unit arranged to selectively control the light sources of the first plurality of light sources such that the lighting device forms a screen in the first region of the optical element, with the control unit being arranged to control the light sources of the second plurality of light sources such that the lighting device emits at least one light beam as output from the second region of the optical element that participates in the performance of a predetermined regulatory signaling function.
