    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.

    Abstract: A reflector for a vehicle headlamp capable of generating a light beam and directing it with respect to an optical axis in order to illuminate the surrounding space according to a predetermined luminosity distribution is described. The reflector is subdivided into a plurality of reflecting sectors capable of reflecting the light emitted from a light source located along an optical axis of the headlamp in order to obtain the said luminosity distribution. Each segment of the reflector is formed by a portion of a surface having rotational symmetry about a corresponding axis. This axis is orientated with respect to the optical axis of the headlamp in such a way that the corresponding sector is capable of directing the light from the light source into a predetermined spatial region of the luminosity distribution.
