Lighting apparatus for vehicles

摘要

The device has a light source (S) e.g. side emitter type LED, arranged in a flat coupling zone (ZC) of a flat and transparent light ray guiding sheet (NG) that is in a form of a screen. The sheet has a light emitting zone (ZE) whose rear side includes longilineal shaped prismatic elements (EP) that are in a form of notches such that light rays are propagated in the sheet and attain the elements leaving from the sheet by a front side to create longilineal lighting surfaces corresponding to the elements. The zone (ZC) has an edge reflecting a light by deposition of aluminum reflecting coating.
