Headlight Patents (Class 362/507)
  • Patent number: 8733992
    Abstract: A fog lamp for a vehicle is disclosed. Light leaving an LED is collected by a refractive/TIR lens. The central portion of the refractive/TIR lens is purely refractive, while the peripheral portion of the lens includes a total internal reflection off an exterior surface of the lens. The refractive/TIR lens converges the light to a focus at or near a laterally-elongated aperture in a light baffle. Light exiting the aperture diverges and passes through an anamorphic lens, which reduces the angular extent of the beam in the vertical direction and increases the angular extent in the lateral direction. The full fog lamp may include multiple pairs of LEDs and respective refractive/TIR lenses, all arranged coplanar, parallel and laterally adjacent to each other. The LED/lens pairs may all direct light through a single light baffle and through a single anamorphic lens.

  • Patent number: 8469568
    Abstract: A vehicle light having a plurality of optical units utilizing a semiconductor light emitting device as a light source can effectively prevent or suppress illuminance unevenness. One example of such a vehicle light can be a vehicle headlamp that includes four optical units each having a semiconductor light emitting device as a light source. The optical units can be arranged in line in the vehicle width direction so as to prevent the luminance unevenness, which can otherwise be generated due to a gap between optical units disposed in a vertical two-stage arrangement.

  • Patent number: 8444306
    Abstract: The present disclosure sets forth a composite headlight assembly which increases the visibility and sight afforded to the driver of a vocational truck using such a composite lighting assembly. A composite lighting assembly includes a low beam light and a high beam light, as well as a turn signal and a parking light within one composite housing. As the overall size of the housing is limited by the size of the grill of the vehicle, the present disclosure increases the visibility and sight afforded to the driver by taking advantage of the untapped space within known composite headlight assemblies. More specifically, the turn signal and parking light may include a downwardly depending trapezoidal appendage increasing the overall area of the turn signal and parking light by at least ten percent.

  • Patent number: 8439544
    Abstract: This invention relates to a vehicle headlamp (1) with a base body (2) containing at least one light module (3) for emitting low beam light, whereby the low beam light is emitted at a specified angle or within an angle range. The invention envisages that the fixture of the light module (3) in the headlamp (1) must have at least one expansion joint (5), whereby temperature-related deviations in the emission of the low beam light from the specified angle or the specified angle range can be compensated by the temperature-related expansion of the expansion joint (5).
