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.

Abstract: A controlled-luminance lighting device comprising a fluorescent lamp (1), which extends longitudinally between a primary reflector (2) and a secondary reflector (3). The primary reflector (2) is formed by a plurality of cup-like elements (4) set alongside one another, having a generally parabolic shape, through which there extends the lamp (1), and the secondary reflector (3) is constituted by a tray-like element with a curved surface. The primary reflector (2) further includes a tile (9), which extends longitudinally between each pair of cup-like elements (4).

Abstract: High-density polyethylene (HDPE) is used as a coating for optical elements operating in transmission in the infrared spectrum, which are made up of a material other than polyethylene, such as hygroscopic salt, semiconductor materials, fluorides, chalcogenides, silver halides, and others, so as to exploit the optical properties of HDPE, at the same time keeping the thickness reduced.
