    Abstract: An optical module for projecting a light beam comprises a solid body of transparent material into which a light source is sunk and which is delimited by an annular surface and by a central surface, and a substantially annular reflecting surface arranged around the solid body. The central and annular surfaces are suitable for receiving respective distinct portions of the luminous flux produced by the source. The reflecting surface may have a reflecting coating or may form part of a transparent body, in which case it works by total internal reflection. The reflecting surface reflects a portion of luminous flux refracted by the annular surface and shapes the flux into a predetermined distribution of luminous intensity about the principal axis. The annular surface is designed in a manner such as to reduce the overall thickness of the module by moving the refracted ray away from the principal axis. The central surface shapes the other portion of the luminous flux emitted by the source into a predetermined distribution of luminous intensity about the principal axis. The surfaces cooperate so as to shape the luminous flux as a whole emerging from the source into a distribution of luminous intensity having divergences which may be different in two directions that are perpendicular to one another and to the principal axis.

    Abstract: The lighting device comprises a light source and an associated hollow reflector of transparent material having an internal surface and an external surface which are close to and far away from the source respectively. The inner surface of the reflector has in cross section at least one transverse plane passing through the source a discontinuous profile forming a plurality of adjacent steps each of which has a first face through which rays originating from the source can pass and a second face essentially parallel to the rays originating from the source. The outer surface of the reflector has a profile comprising one or more arcs of curves. The reflector is constructed and positioned in such a way that in the said transverse plane most of the rays emitted by the source are reflected through the first face of the steps on its inner surface and strike its outer surface undergoing total internal reflection and after passing back through the reflector emerge from it through the second faces of the steps on its inner surface undergoing a second refraction.
