Abstract
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.
