<p>A ventilated headlamp for vehicles has a reflector (2) produced by an injection-moulding or die- casting process. The interior (1) is sealed off from dirt and water spray and for its ventilation a groove (16), which is open towards the rear, is provided in a ring (11, 12) which surrounds a reflector opening (7) for receiving the bulb and which is made integral with the bulb socket or holder (9) secured to the reflector. The groove is covered by a sealing cover (13, 14). The reflector has a stepped back as a result of sections (3, 4, 5, 6) with different parabloids. The ring rests on a surface (10) formed from an extension of the reflector to locate the bulb socket in the direction of the optical axis. <IMAGE></p> |
