## Abstract

A lighting device for a vehicle, the lighting device being configured to perform at least one lighting function and including at least one optical module, an output lens and a housing including the at least one optical module, with the lighting device including a textured film covering a surface of the device, the textured film having patterns configured to reduce the transmission of light entering the lighting device through the surface.

## Claims

### Claim 1

A luminous device for a vehicle, the luminous device being configured to perform at least one luminous function and comprising at least one optical module, an outer lens and a housing containing the at least one optical module, with the luminous device including a textured film covering a surface of the luminous device, the textured film including patterns configured to reduce the transmission of light entering into the luminous device through the surface.

### Claim 2 (depends on 1)

The luminous device as claimed in claim 1, wherein the surface is covered in whole or in part by the textured film.

### Claim 3 (depends on 1)

The luminous device as claimed in claim 1, wherein the surface is a face of the outer lens.

### Claim 4 (depends on 1)

The luminous device as claimed in claim 1, wherein the surface is a face of an intermediate element placed between the optical module and the outer lens.

### Claim 5 (depends on 1)

The luminous device as claimed in claim 1, wherein the patterns are surface patterns or volume patterns.

### Claim 6 (depends on 5)

The luminous device as claimed in claim 5, wherein the surface patterns are produced using an IML or IMD process.

### Claim 7 (depends on 5)

The luminous device as claimed in claim 5, wherein when the patterns are surface patterns, they are formed by an ink deposit with a thickness of between 1 and 10 microns.

### Claim 8 (depends on 1)

The luminous device as claimed in claim 1, wherein the patterns are occulting or semi-transparent.

### Claim 9 (depends on 1)

The luminous device as claimed in claim 1, further comprising a mask.

### Claim 10 (depends on 1)

The luminous device as claimed in claim 1, wherein the luminous function is an illuminating function, a signalling function, a styling luminous function, or an enhanced luminous function.

### Claim 11 (depends on 1)

The luminous device as claimed in claim 1, wherein the patterns are continuous lines or punctual patterns.

### Claim 12 (depends on 1)

The luminous device as claimed in claim 1, wherein there is a pitch between the patterns and the pitch has a maximum value of 0.8 mm between the center of two patterns.

### Claim 13 (depends on 1)

The luminous device as claimed in claim 1, wherein the surface including the textured film is configured to transmit light variably.

### Claim 14 (depends on 1)

The luminous device as claimed in claim 1, wherein the patterns are arranged so that there is a variable pitch between the patterns and/or so that the patterns have a variable material density and/or so that the patterns have a variable area.

### Claim 15 (depends on 1)

The luminous device as claimed in claim 1, wherein the patterns form a negative image of punctual patterns, the punctual patterns being substantially transparent.

### Claim 16 (depends on 15)

The luminous device of claim 15, wherein the surface including the textured film is configured to transmit light variably.

### Claim 17 (depends on 16)

The luminous device as claimed in claim 16, wherein the punctual patterns are arranged so that there is a variable pitch between the punctual patterns and/or so that the punctual patterns have a variable area.

### Claim 18 (depends on 17)

The luminous device as claimed in claim 17, wherein the negative image comprises different areas with different material densities.
