An optical component has working surfaces separated by neutral surfaces which constitute discontinuities between the working surfaces. The component is made by a method which comprises: forming, in a mould, surfaces complementary to the working and neutral surfaces of the component; and moulding the component on these surfaces of the mould. The step of forming the complementary surfaces in the mould is carried out by continuous cutting of a block of material using a cutting tool.

Method of making an optical component, a mould for use in such method, and an optical component so produced

An indicator lamp for a motor vehicle includes a plurality of light sources, and a plurality of linking elements. The lamp includes components that straighten out the light emitted by the light sources so that the light is propagated in a direction essentially parallel to a general direction of emisssion. These components include multiple first elements and a second element. East first element corresponds to one of the plurality of light sources. The first elements are able to distribute the light in a plane essentially perpendicular to the general direction of emission, in an essentially uniform way onto the second element. The second element is able to straighten out the incident light towards the general direction of emission.

Indicator lamp with simplified optical structure

An indicator light comprises a source, an optical plate adapted to straighten out the incident light towards an average direction generally parallel to an optical axis, and a flux-distributing and recuperating cup interposed between the source and the plate in order to distribute the light over the inner surface of the plate. According to the invention, the optical plate has a height and a width of the same order of magnitude and possesses optical configurations having varied coefficients of transmission of the light, and the cup provides a given distribution of the light, both in the horizontal direction and in the vertical direction, which takes account of said coefficients. As a result, an illumination is obtained at the exit from said plate which is essentially constant in the horizontal direction as well as in the vertical direction.

Indicator light with uniform illuminating surface for a motor vehicle

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.
