Patent ID: 7455438

Claim:
A module for projecting a light beam, comprising a light source and a substantially flat support surface on which the source is arranged in a manner such as to emit light from only one side of the surface, and means for reflecting the light emitted by the source, wherein the reflecting means comprise a curved reflecting surface which extends on one side of the support surface and has a concavity facing towards the support surface, wherein the reflecting surface has a longitudinal section, perpendicular to the support surface, which has a substantially parabolic shape with an axis substantially parallel to the support surface, and a transverse section, parallel to the support surface, having a substantially conical curve shape, in such a way as that the reflecting surface is adapted to reflect the light coming from the source in a principal direction substantially parallel to the support surface of the source thereby generating a predetermined luminous intensity distribution, wherein the curved reflecting surface is formed by a plurality of sectors which are connected discontinuously so as to form discontinuities of profile or of curvature, wherein each sector presents predetermined values of spread of the light reflected by it in a direction perpendicular to the support surface, said sectors being delimited by isospread curves at which the spread adopts a constant value, and wherein each sector is arranged to convey the light emitted by the source in a respective zone of the luminous intensity distribution.
