Abstract
A lighting device for motor vehicle comprising a light source configured to emit light rays; an optical system optically coupled to a first portion of said light rays and configured to output said first portion of the light rays to provide a vehicle lighting function; and a mask optically coupled to a second portion of said light rays. The mask is configured to pass a projecting part of said second portion of the light rays and to cut off passage of a blocked part of said second portion of the light rays such that the second portion of the light rays forms a pattern of light and shadows on a surface.

11. :
- A method of manufacturing a mask for a lighting device of a motor vehicle, the lighting device for motor vehicle comprising a light source configured to emit light rays;
a mask including a first aperture and a second aperture, said light rays passing through the first aperture corresponding to a first portion of said light rays, said light rays passing through the second aperture corresponding a second portion of said light rays, and, an optical system receiving said first portion of said light rays and configured to output said first portion of the light rays to provide a vehicle lighting function, said second portion of said light rays forming a pattern of light and shadows on a surface the method comprising; creating a pattern of light on the surface that the pattern will be created on; breaking a contour of the pattern into multiple curves; creating surfaces from the curves and the light source; getting a solid structure from the surfaces; and subtracting solid from the actual mask to get the apertures. - View Dependent Claims (14, 15)
