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 assembly is provided which includes a light bulb providing a source of illumination; a reflector housing with a central opening with a reflector surface for reflecting illumination given by the light bulb, the reflector housing central opening mounting the light bulb, the reflector housing having a first surface opposite the reflector surface adjacent the central opening and a second surface on the same side of the reflector surface generally adjacent the central opening; and a bulb shield having a first portion along a first end. The first portion is generally closely adjacent to the light bulb for blocking illumination provided by the light bulb. The bulb shield has at an end opposite the first end at least one foot penetrating through the central opening with a radially outwardly extending toe engaging the reflector housing first surface. The bulb shield also has a coil spring contacting the reflector second surface urging the first end of the bulb shield away from the first and second surfaces of the reflector housing.

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.

摘要： A vehicular headlamp which provides a high beam of good visibility. The inventive vehicular headlamp includes first and second headlamp main bodies, and at least a light source and a reflector for reflecting the light of the light source forwardly. The second headlamp main body includes an integrated light projection unit which is composed of a reflector formed in a substantially ellipsoidal shape, a light source disposed at a first focal point of the reflector, a projection lens disposed in front of the light source for projecting and distributing forwardly light reflected from the reflector, and a shade disposed at the focal point of the projection lens for forming the low beam. The second headlamp main body forms the low beam and cooperates with the first headlamp main body in forming the high beam. The headlamp is characterized in that a shade for reducing the amount of light emitted is disposed at a position offset rearward and forward from the focal position of the projection lens with respect to the optical axis of the light projection unit and on the opposite side to the low beam forming shade with the optical axis therebetween.
