Lighting device including a light ray guide

摘要

A lighting and/or signaling device and a light ray guide (N) formed by a guide plate comprising a light entry face, a light exit face and a reflection face having an elliptical profile toward the rear adapted to assure reflection of light rays entering the guide plate through the light entry face toward a focus point (F) located at the level of the light exit face of the guide plate.

主权项

1. A light ray guide (N) comprising:
a plurality of guide plates, each of said plurality of guide plates being generally planar and comprising a light entry face, a light exit face and a reflection face having an elliptical profile toward a rear of said guide plate and being adapted to assure reflection of light rays entering said guide plate through said light entry face toward a focus point (F) located at a level of said light exit face of said guide plate; wherein a light source is associated with each of said plurality of guide plates, said light source being disposed at a level of said light entry face, said plurality of guide plates being arranged in a fan arrangement, said plurality of guide plates being tangential at a level of their exit face and diverging progressively to produce a spacing between each light source; said light ray guide producing a beam made up of an assembly of a plurality of vertical pixels, each vertical pixel notably being produced from said light source that can be turned off or turned on on command from a control system connected to said light source.
