Abstract

A light-signaling system includes three lighting modules, each including two projectors fixed together. Each projector includes an elongated cylindrical lens defined by a horizontal generatrix direction, and a linear light source parallel to the generatrix direction, for emitting a luminous flux. The cylindrical lens is capable of generating and projecting a main flat light beam within a predefined azimuthal angular sector that is greater than 60°. The two projectors of the same lighting module are arranged such that the generatrix direction of the first projector and the generatrix direction of the second projector form an angle of 120° the bisectrix of which defines the main direction of the lighting module.

Abstract

A light projector intended to produce a directional flat light beam includes an elongate cylindrical lens and a linear light source parallel to the generatrix direction, extending over all or part of the length of the lens to emit light in the direction of the lens. The lens is designed to generate a principal flat light beam by concentrating the light in a predefined elevation angular sector around the horizontal generatrix direction. The light projector also includes a deflector having a rectangular plate shape positioned on the side opposite the light source. A signalling beacon including such a projector is also described.
