Abstract

The light has a case (1) closed by a frontal lens (2) and in which a support plate (3) is mounted for carrying light emitting diodes (4). A transparent collimation plate (5) has a collimation lens (6) and a cylindrical diffusion lens (7) curved towards the diodes and frontal lens, respectively. An anti-phantom screen (11) is interposed between the collimation plate and frontal lens. The screen has opaque segments delimiting slits (14).
