Lighting device for a rear license plate of a motor vehicle

摘要

Lighting device for a rear license plate of a motor vehicle, which comprises a support wall (3) bearing the license plate (2), to which a wall area that forms a visor (4) and protruding backwards with an approximately horizontal surface in the direction of the vertical axis of the vehicle above the license plate (2), as well as at least one recess (8) on the side of the visor with a light source (13) located above it, in which the recess (8) is covered by a light-permeable optical glass (9) such that the optical glass (9) covers from below with a covering edge (11) an edge of seat (12) surrounding the recess (8), in which a light irradiated by the light source (13) through the optical glass (9) and provided with a predetermined light density is irradiated through the surface within the cover edge (11) towards the license plate (2), and in the that the optical glass (9) has at least one zone (19) of defined width that extends along at least a partial area of the optical glass (9) and that has a definitively smaller light permeability compared to the light-permeable zone of the optical glass (9) and forms several irradiation zones (35, 36) of the optical glass (9) and / or separates them from one another in at least certain zones, characterized in that the zone (19 ) Definitely more impervious to light extends as a separation zone from the rear zone (16) of the coverage edge of the optical glass (9), seen in the longitudinal direction (x) of the vehicle, along at least one zone part of the optical glass (9) and extends in the center between two irradiation zones (35, 36) of the optical glass (9) juxtaposed in the transverse direction of the vehicle, and because the optical glass (9) has at least one driving element (15, 30) and / or deviation of light that conducts and also light towards at least a partial zone of a rear zone (16) of the covering edge (11), seen in the longitudinal direction of the vehicle, and radiates it from there with a predetermined luminous density towards the license plate (2) .
