Indicating light with homogeneous illumination, including smooth zones
First Claim
1. An indicating light defining an optical axis and comprising:
- a light source;
a bonnet in front of the light source; and
an optical plate in front of the bonnet, the optical plate having a light receiving surface facing the bonnet, the bonnet having distributing means for distributing radiation received by the bonnet from the light source, substantially uniformly over at least part of the said surface of the optical plate, the optical plate having striations on said surface for aligning the radiation received from the bonnet in the direction of the optical axis, wherein the striations on the optical plate are grouped in at least one discrete zone thereby defined on the said surface, the remainder of the said surface comprising at least one optically neutral zone, the said distribution means being adapted to direct at least part of the radiation received from the light source towards the said discrete striated zones.

Abstract
A rear indicating light for a motor vehicle comprises a light source, a bonnet in front of the light source, and an optical plate in front of the bonnet. The bonnet has means for distributing essentially uniformly the radiation it receives from the light source, over at least part of the surface of the flat optical plate, which is formed with striations to align the radiation along the optical axis. These striations are grouped in at least one discrete zone on the surface of the plate, the remainder of this surface consisting of at least one optically neutral zone, while the distributing means are adapted to distribute at least some of the radiation from the light source towards the discrete striated zones.
