Light device for motor vehicles
A light device for motor vehicles, especially a signal lamp, comprises a carrier housing ( 1 ), covered by a translucent cover ( 2 ), and an inner chamber ( 3 ) wherein at least one light source for generating light rays is mounted, and a transparent optical part ( 5 ) with at least one output surface for the output of at least a part of light rays from the transparent optical part. The light device further comprises at least one macrotexture ( 8 ) the surface of which consists of individual surfaces designed for transmission and/or reflection of a part of light rays, the macrotexture and the transparent optical part arranged in such a way that in a view of the inner chamber ( 3 ) towards the output surface through the translucent cover from the outside of the light device, the impression of a spatial effect is produced, which is even visible with the light source being off.

6. The light device in accordance with claim 1 , wherein the at least one macrotexture comprises at least one unbinding surface configured to unbind light rays passing through the unbinding surface to another part of the transparent optical part and/or out of the transparent optical part.
7. The light device in accordance with claim 1 , wherein the at least one macrotexture comprises at least one binding surface to bind light rays passing through the binding surface to other parts of the light device.
8. The light device in accordance with claim 1 , wherein the at least one macrotexture comprises at least one reflective surface adapted to reflect light rays falling onto the reflective surface.
9. The light device in accordance with claim 8 , wherein the reflective surfaces of the macrotexture are preferably geometrically arranged for uneven output of light rays from the output surface of the transparent optical part to produce the light image including brighter and darker areas, wherein the light image is visible from the outside looking at the light device.
10. The light device in accordance with claim 1 , wherein the transparent optical part is created as a compact casting.
11. The light device in accordance with claim 1 , wherein in a propagation direction of the light rays generated by the light source, an optical element for routing the light rays to a required direction is arranged before the transparent optical part.
