Abstract (en)

[origin: EP1632710A2] The lamp has a stepped plane (20) and a parabolic mirror (22) to reflect light rays emitted by a light source (16) on a rear side (23) of a distributing screen (24). A Fresnel lens (38) is interposed in the path of the rays, between the source and the plane (20). The lens adjusts the rays to permit reflection of the rays on facets (32) of the plane (20) along a longitudinal direction oriented towards front.
