<p>The light has reflectors for reflecting luminous ray emitted by a filament of a halogenous bulb. A lens (5) eventually diffuses reflected rays by the reflectors through an area of illumination (51). The reflectors comprise two catadioptric elements (52) that are symmetrically arranged on a surface of the lens in a remote region of the electrodes of the halogenous bulb. The catadioptric elements approximately cover angular sectors of a surface of the lens. The surface of the lens comprises prisms in the area of illumination. External diameter of the lens is less than or equal to 53 mm.</p> |
