摘要: A high voltage electric-discharge lamp is used as a light source of a headlight device for use in an automobile vehicle. Light from the discharge lamp is reflected on the curved surface of a reflector disposed at a back side of the discharge lamp, and projected forward. To reduce high frequency electromagnetic noises emitted forward from the device, which interfere with radios and televisions mounted on a vehicle driven ahead, a shade to intercept light emitted directly forward from the discharge lamp is disposed in front of the discharge lamp, and the shade is grounded. To further enhance noise reduction effects, a second grounding passage is provided. The second grounding passage is formed by grounding terminals attached to the shade and a wire connecting the terminals to the ground. Other components constituting the headlight device may be also grounded to secure a higher shielding effect. The electromagnetic noises interfering with radios and televisions mounted on a vehicle driving ahead are sufficiently reduced to a harmless level.

摘要: A vehicle headlamp having a paraboloidal reflector and an electric lighting bulb mounted in a lighting chamber. The paraboloidal reflector is formed to include a pair of vertically opposed flat portions extending therefrom toward a cover lens. The bulb has a vitreous envelope containing a primary filament for providing an upper beam, and an auxiliary filament for providing a lower beam. A shade is disposed between the bulb and the upper flat portion of the reflector in order to prevent the bulb from directly irradiating the upper flat portion of the reflector. Characteristically, the shade is inclined with respect to the optical axis of the headlamp, instead of being disposed parallel thereto, so as to extend in a direction in which the rays of light emitted by the axuillary filament of the bulb travels after having been reflected by part of the paraboliodal reflector, in order to make utmost use of the light rays emitted by the auxilliary filament for providing the lower beam.
