Abstract

1,252,145. Vehicle headlamps. PROJECTEURS CIBIE. 4 Dec., 1968 [19 Dec., 1967], No. 57531/68. Heading F4R. A headlamp comprises a first iodine lamp 2 having a filament 2a which is shielded by a masking element 3 and is disposed slightly in front of the focus F1 Of a main paraboloidal reflector 1 so that it produces a dipped beam, and a second iodine lamp 5 located with its filament 5a at the focus of an auxiliary paraboloidal reflector 4 to produce a main beam. The aperture of the auxiliary reflector has a diameter substantially equal to half that of the aperture of the main reflector, and the edge of the aperture of the auxiliary reflector is substantially tangential to the plane or planes of cut-off defined by the masking element 3. The axis of the auxiliary reflector is laterally displaced relative to the vertical plane through the axis of the main reflector. The auxiliary reflector is adjustably mounted on the main reflector by means of a flexible connection 7 and a control screw 8.
