  • Patent number: 6190028
    Abstract: A surface-coated, molded resin article for vehicles composed of a substrate (100) made of a resin, a plate layer (101) formed on the surface of the substrate (100) and coating films formed on the surface of the plate layer (101) wherein two or more different silicone-based coating films (102), (103) containing UV absorbers are laminated on each other. The lower coating film (102) is a light-reflective pearl film, while the upper coating film (103) is a film having a desired color. The UV rays are absorbed by the UV absorber contained in each coating film, to reduce the amount of UV rays that reach the interface between the plate layer 101 and the coating film 102, thus, peeling of the coating films can be effectively prevented. The lower coating film 102 reflects the external rays and provides a glossy appearance, thus contributing to the improvement in the appearance as a metallic coating.

  • Patent number: 6179456
    Abstract: A lamp for use in adverse conditions such as in a headlamp for a vehicle includes a coating for preventing mist, condensation or other haze from forming on a front lens and/or for preventing discoloration of the front lens caused by UV light emitted from a light source. The lamp has a discharge-lamp bulb serving as the light source, the discharge-lamp bulb being disposed in the lamp chamber. The lamp chamber can be defined by the lamp body and the front lens. The coating can comprise an anti-haze/UV film that is prepared by mixing a UV absorbing material with an anti-haze material.

  • Patent number: 6149287
    Abstract: A mirror assembly security system for a vehicle includes an exterior mirror assembly and a light module removably positioned within the exterior mirror housing. The light module is moisture impervious and includes an enclosure, a light-emitting opening in the enclosure, a light source in the enclosure radiating light through the light-emitting opening, and a cover for the light-emitting opening adapted to direct the light from the light source to an area adjacent the vehicle to create a security area. The light source may be supported by a pair of electrical contacts provided on the inner surface of the enclosure. The enclosure wall supporting the electrical contacts is preferably flexible, in order to allow the light source to be captured by the contacts. Attachment of the cover adds rigidity to the enclosure to prevent further flexure of the enclosure wall in order to firmly retain the light source.

  • Patent number: 6086229
    Abstract: A mirror assembly security system for a vehicle includes an exterior mirror assembly and a light module removably positioned within the exterior mirror housing. The light module is moisture impervious and includes an enclosure, a light-transmitting opening in the enclosure facing generally downwardly and/or rearwardly of the vehicle, a cover for the light-transmitting opening, and a light source in the enclosure radiating light through the light-transmitting opening. The light source may be received in a socket which removably engages another opening in the enclosure. In this manner, the light source may be replaced by removing the module from the exterior mirror housing, removing the socket from the enclosure and replacing the light source. The enclosure and mirror housing preferably are configured to self-retain the module in the exterior mirror moving with no, or fewer than one or two, separate fasteners.

  • Patent number: 6050706
    Abstract: A vehicle lamp includes an amber light bulb covered with a cup-shaped colorless transparent cap, thus emitting an amber light beam. A colorless, transparent, plain lens is employed. Furthermore, the inner surface of the cylindrical portion of the transparent cap is formed into a plurality of side steps, and the inner surface of the front end portion of the transparent cap is shaped into a Fresnel lens, and the outer surface of the front end portion is shaped into a plurality of fisheye lenses, which makes it more difficult to see the amber light bulb. Therefore, the vehicle lamp appears deep and glittering.

  • Patent number: 6030104
    Abstract: A soft shelled lamp shade comprising: a shade body formed of soft plastics having good light transmission and heat resistance, the shade body having a bottom surface with a hollow cylindrical body projected therefrom, a recess being formed on the bottom surface around the cylindrical body, a receiving chamber being further formed within the shade body, the receiving chamber being opened at a hollow end of the cylindrical body, and a double-sided adhesive tape being in the shape of a sheet and having an upper and a lower surfaces, the upper surface being at least partially adhered into the recess on the bottom surface of the shade body. Since the shade body is formed of soft light conducting and heat resistant plastics, the shade body can be made into any desired shape. When the soft shelled lamp shade and a set of bulbs are secured to an automobile or a motorcycle, light can be emitted through the shade body from the bulbs.

  • Patent number: 5975728
    Abstract: The present invention comprises a method and apparatus for providing user selectable multi-color illumination to automotive instrument panel instruments. In one embodiment, an instrument panel or individual instrument is supplied with a plurality of differently colored illumination sources. The intensity of each color is individually controllable, allowing the user to select both intensity and hue of instrument illumination. In one embodiment, an instrument panel illumination system comprises three light sources that produce nominally white light and three associated diffusing filters, one red, one green, one blue. In another embodiment different colors of illumination are provided by light sources producing different colors of light, such as, for example, a plurality of high intensity red, green, and blue light emitting diodes ("LED's"). In one embodiment, a plurality of triplets of red, green and blue high intensity LED's are mounted above a white diffusing filter.

  • Patent number: 5971575
    Abstract: A vehicle headlamp including a bulb for emitting a light, a reflector having an optical axis and a reflecting surface for reflecting light received from the bulb in a forward direction, for a shade fitted to the reflector and shielding the light emitted from the bulb. The shade includes a light-shielding section which shields the light traveling from the bulb to lower right and left regions on the reflecting surface, a bridge section extending in a circumferential direction of the optical axis of the reflector, and mounting legs, each having a front end and a rear end, which are connected at the front ends to the bridge section and are connected at the rear ends to the reflector.

  • Patent number: 5961208
    Abstract: A high intensity discharge lamp, suitable for use as a headlight for land, rail, water, aircraft, and motor vehicles in particular. The lamp includes glass containing Neodymium Oxide, a rare earth compound. The Neodymium Oxide filters out the yellow light portion of the spectrum, thereby producing a color corrected light. Incorporation of yellow light in the light spectrum desaturates colors and reduces contrast. Improvement in contrast and a reduction in glare permits, for example, a motor vehicle driver to better discriminate the contrast of objects when there is no daylight and the only illumination is artificial. For drivers, in particular, elimination of the yellow light lessens eye strain currently resulting from light emitted by the conventional headlights of oncoming vehicles during hours of darkness.
