  • Patent number: 7524075
    Abstract: A shock absorbing mounting for a rotating warning light for a light bar is provided by the assembly of the rotator with a base member useful for mounting one or more rotators and other light producing array units. The light bar base member has longitudinal grooves and the mounting enables the rotator to be attached wherever desired along the grooves. The grooves are blind grooves. The rotator has its own base with a plurality of holes in which are provided resilient shock absorbing grommets with holes therethrough. The assembly of the rotator to the light bar base member is via self-threading screws which have heads, parts of which may be washers, which enlarge the diameter of the heads. The screws are of such length that when they engage and are stopped by the bottom of the grooves, the head compresses the grommet sufficiently to provide a resilient shock absorbing connection.

Preferably, two modules are mounted at the front of the automobile to function as headlights, and two of the modules are mounted at the rear of the automobile to function as taillights. Each module has a beam emitter which produces an initial beam of laser light and an output mirror which directs an exit beam through the lens, outwardly of the automobile, and ultimately creates a cone of light at the ground surface forwardly or rearwardly of the automobile. When used as a headlight and the mode selection switch is appropriately set, an output mirror rotation motor spreads the output beam so that it creates a larger cone on the ground surface.

  • Patent number: 6554460
    Abstract: A motor vehicle headlight of the elliptical type, giving both a dipped beam and a main beam, has a light source which cooperates with a reflector to produce a patch of light, with a lens projecting the patch of light on the road, and a movable mask being arranged so that, in a working position, it masks a part of the light patch so that the lens produces a cut-off beam, while in an inactive or retracted position of the mask, the lens projects essentially the whole of the light patch so as to produce a beam without any cut-off. The reflector comprises a first zone which produces a first part of the light patch, not significantly masked by the mask in its working position, and a second zone which produces a second part of the light patch. This second part is cut off by the mask in its working position to a much greater extent. The two parts of the light patch have different distributions of the light in a direction transversely to the direction of projection.

  • Patent number: 6550944
    Abstract: A vehicle headlamp has a unit pivot control mechanism for laterally moving the luminous intensity distribution of a lamp unit by laterally pivoting the lamp unit according to the travel conditions of the vehicle, and a luminous intensity variable control mechanism for varying the luminous intensity distribution by moving a shade of the lamp unit according to the travel conditions of the vehicle. Beam emission can be carried out at emission angles with the luminous intensity distribution conforming to the travel conditions of the vehicle by properly combining beam emission control performed by the unit pivot control mechanism and the luminous intensity variable control mechanism. The result is improved visibility of a road surface ahead of the vehicle.

  • Publication number: 20020191411
    Abstract: A vehicle headlamp structure for engagement between a plunger of a solenoid and a shade leg of a movable shade, wherein the solenoid moves the movable shade to vary the light distribution of a lamp fixture. A movable shade 22 is pivoted between two positions by a solenoid 34 having a longitudinally extending plunger 36. The plunger 36 has a notch (U-shaped recess) 36a formed in its peripheral surface at a position near the tip thereof. A shade leg 22B of the movable shade 22 has an engaging portion 22Ba for engaging with the notch 36a. Since the engaging portion 22Ba abuts on a front end face 36a1 and a rear end face 36a2 of the notch 36a, reciprocating movement of the plunger 36 is converted into pivoting movement of the movable shade 22.

  • Patent number: 6491419
    Abstract: A beam switching device 24 is provided for switching between a low beam and a high beam by rotating a shade 22 for screening part of incident light given off from a discharge illuminant portion 18a to a reflecting surface 20a of a reflector 20. The shade 22 rotates about a rotational axis A extending in a direction which inclines a predetermined angle &THgr; relative to a horizontal plane. A rotational locus of the shade 22 can be inclined relative to a vertical plane. The beam switching device 24 can also be inclined relative to the vertical plane. Thus, a vertical dimension h from an optical axis Ax to a lower end f the beam switching device 24 is made short.

  • Patent number: 6488396
    Abstract: A movable shade 22 capable of shading part of light incident on a reflector 20 from a discharge bulb 18 is pivoted longitudinally by a shade driving unit 24 to switch beams. A shade body portion 22A surrounding the discharge bulb 18 is colored blue. Thus, the blue color of the shade body portion 22A appears to be reflected on the reflector 20 when a lamp is viewed from the front while the movable shade 22 stays in a low-beam position. When a reflective area C reflecting the blue color varies in shape and size as the movable shade 22 moves to a high-beam position, beam switching can be visually confirmed easily.

  • Patent number: 6485168
    Abstract: A headlight device for a vehicle has at least two headlights, each emitting a screened light beam with an upper bright-dark limit, which on a counter traffic side and on a traffic side has different portions. A portion on the counter traffic side is arranged deeper in a vertical direction than a portion on the traffic side, and the portion on the traffic side extends so as to ascend starting from the portion on the counter traffic side over a part of the extension of the portion on the traffic side. The headlights are formed so that the light bundles are emitted with different bright-dark limits. At least one headlight emits a first light bundle with a bright-dark limit, with the portion which on the traffic side is located higher in a vertical direction than the portion of the bright-dark limit at the traffic side of a second light bundle emitted by at least one second headlight.

  • Patent number: 6447151
    Abstract: A variable beam width headlight whose beam width decreases and length increases as velocity of a vehicle increases and whose beam width increases and length decreases as velocity of a vehicle decreases. As the velocity of a vehicle increases or decreases so too does the airflow to the headlights. Therefore, airflow can be used as a measurement of an increase or decrease in velocity. Each headlight has a reflector, a light source within the reflector and an aperture through which a beam passes after light rays from the light source have been reflected from a reflector surface. When the velocity of a car increases, the aperture of the reflector decreases in size resulting in a narrower, longer beam of light allowing the driver to see objects far in the distance. When the velocity of a car decreases, the aperture of the reflector increases in size resulting in a wider, shorter beam of light allowing the driver to see objects nearby that are to either side of him.
