Abstract

A lighting device for vehicles with a number of light sources, a number of reflectors reflecting the light emitted by the light sources into a specified main reflection direction, a number of diffusers scattering the light emitted by the light sources and a lens which is disposed in main reflection direction in front of the reflector and the diffuser. The lens is disposed at a v-shaped angle of a surface normal of the lens toward the main reflection direction of the reflector. A theoretical prolongation of the diffuser in relation to the surface normal of the lens extends in an acute angle of incidence or vertically to the lens. The diffuser is disposed as a separating wall between two reflectors which are disposed on stepped, offset levels and/or the diffuser is disposed as an end wall at a reflector.

Dependent claims

Lighting device for vehicles comprising:

a number of light sources (1);
a number of reflectors (5, 5′, 5′″), by which light (9) emitted by the light sources (1) is reflected in a predetermined main reflection direction (R);
a number of diffusers (3, 3′), by which the light (9) emitted by the light sources (1) is scattered;
a lens (7) disposed in the main reflection direction (R) in front of the reflector r (5, 5′, 5″) and the diffuser (3, 3′);
characterized in that
the lens (7) is disposed at an v-shaped angle (″) between a surface normal (NL) of the same and, the main reflection direction (R) of the reflector (5, 5′, 5″);
a theoretical prolongation (28) of the diffuser (3, 3′) in relation to the surface normal (NL) of the lens (7) extends in an acute angle of incidence (α) or vertically to the lens (7);
the diffuser (3, 3′) is disposed as a separating wall (3) between two reflectors (5, 5′, 5″) disposed on stepped, offset levels and/or as an end wall (3′) at a reflector (5).
