Abstract

966,789. Vehicle headlamps. P. CIBIE. April 30, 1962 [May 4, 1961; May 8, 1961], No. 16509/62. Heading F4R. A headlamp for producing a main and a dipped beam has a single light source with a filament extending along the axis of a reflector, retractable means for partly masking the radiation from the source and correcting means for adjusting the effective position of the source with respect to the focus of the reflector to provide correct lighting when either beam is used. In the form shown the reflector 1, Fig. 1 consists of a paraboloid of rotation top and bottom by flat horizontal sections 2, 3. A tubular lamp bulb 4 with the filament arranged along the axes of the paraboloid close to the focal point is carried by a support 5. Flaps 6a, 6b carried by spindles 7a, 7b parallel to the optical axis are arranged adjacent the filament and can be moved from the position shown, in which they do not affect the light beam from the lamp into a position in which they are extended to mask the upper half of the reflector. The spindles carry masking pinions 8a, 8b and the spindle 7a carries a magnet 9 arranged between the polepieces 10 of an electromagnet 11, energization of which causes the flaps to be extended against the action of a return spring 12. A nut 14 on the support 5 engages a screw thread 13 on the spindle 7a so that the bulb is moved away from the focus of the reflector when the flaps are opened. In a modification, the flaps 29, 29a, Fig. 8, are mounted on coaxial spindles each of which carries a magnet 36 and 37 (not shown) and both of which are acted upon by one or other of a pair of polepieces 40, 41, connected to the cores of associated coils 42, 43, energization of one coil opening and of the other closing the flaps. A single coil having a polarity reversing relay or a single coil acting in opposition to a return spring may be used. Alternatively, the bulb may be stationary and the reflector consist of two half-paraboloids connected by a horizontal plane, the bulb being situated at the focus of the lower half-paraboloid and away from the focus of the upper half-paraboloid which produces the dipped beam. Instead of modifying the reflector, the front lens of the lamp may consist of a lower half through which the dipped beam passes and which may be fluted and an upper half in the form of a stepped lens.
