Abstract

An optical lighting unit, especially for motor vehicle headlamps, comprises a transparent lens 1 made of plastics material and a reflector provided with means for locating at least one lighting bulb, the optical unit being characterised in that it has a reflective metal surface 11 provided with surface irregularities to disperse towards the interior of the unit at least the thermal radiation of the light beam reflected by the reflector, this surface being situated at least at the level of the central area of the lens and close to, or on, its internal wall. The surface may be a coating, an insert or a separate disc disposed at a small distance from the lens.
