  • Patent number: 9074746
    Abstract: A rear combination lamp for a vehicle is disclosed, in which facets on a reflective surface impart relatively large angular deviations to their respective reflected beams. Reflected light from each facet is only visible over a particular angular range. The angular ranges for all facets overlap only in a predetermined manner, so that at a given viewing angle, light from only particular facets is visible. The appearance of the rear combination lamp varies as a function of viewing direction. As a viewing angle changes, light from certain facets becomes visible, and light from other facets becomes invisible. This changing subset of which facet reflections are visible produces a sparkling or twinkling effect from the rear combination lamp. In some designs, the sparkling can take on a pattern that moves across the rear combination lamp, as the viewing angle changes.

  • Patent number: 8992059
    Abstract: A vehicle lighting device includes first and second light sources and a light guide lens that is elongate and extending along a direction oblique to a front-back direction of a vehicle. The first light source faces with a back end portion of the lens in a longitudinal direction of the lens. The second light source is arranged close to a front end portion of the lens in the longitudinal direction to emit light toward a back surface of the lens. The lens has a plurality of cut portions in the back surface. The cut portions are arranged parallel with each other in the longitudinal direction, internally reflect the light emitted from the first light source and enters the lens through the back end portion to a forward direction of the vehicle, and refract the light emitted from the second light source and enters the lens to the forward direction.

    Abstract: A vehicular lamp unit has a substrate, a light source having a first light-emitting element and a second light-emitting element disposed on the substrate, and an optical element having the light source attached thereto. The substrate is long in a first direction. The optical element radiates emitted light of the first and second light-emitting elements toward a front of the vehicular lamp unit, with a desired light distribution. A reference portion serving as a positioning reference for the optical element is provided in a part of the substrate. The first and second light-emitting elements are arranged in the first direction. The first light-emitting element illuminates an area having high light intensity of the light distribution. The second light-emitting element illuminates an area having low light intensity of the light distribution. The first light-emitting element is mounted at a position closer to the reference portion in the first direction than the second light-emitting element.

  • Patent number: 8956027
    Abstract: A projector lens of a vehicular headlamp has a shape of a convex lens in which the upper and lower portions are cut by a predetermined amount. A light source is disposed above optical axis Ax of the projector lens while a light emission surface is inclined downwardly. A first reflecting mirror has an elliptical reflective surface, and is adjusted in size such that almost all the light reflected from the reflective surface is incident on the projector lens. A shield plate is disposed in the vicinity of the focus of the first reflecting mirror to form a horizontal cutoff line. A second reflecting mirror is disposed to reflect light that is not incident on the first reflecting mirror. The third reflecting mirror is disposed above the upper end of the shield plate at a position that does not interfere with the light reflected from the first reflecting mirror.

  • Patent number: 8920011
    Abstract: The present invention is provided with a semiconductor-type light source 2 and a reflector 3. The reflector 3 has reflection surfaces 31U to 31D. The semiconductor-type light source 2 is disposed at or near a reference focal point F of the reflection surfaces 31U to 31D. The reflection surfaces 31U to 31D are divided into upper and lower sides in a direction in which light is to be radiated from the semiconductor-type light source 2, with respect to an X axis passing through a center O of the semiconductor light source 2 or its proximity. Among the upper and lower reflection surfaces, on the upper side, convergent scattering reflection surfaces 31U to 34U are disposed, and on the lower side, divergent scattering reflection surfaces 31D to 34D are disposed. As a result, the present invention is capable of forming an approximately ideal light distribution pattern HPA for high beam.
