  • Publication number: 20150300589
    Abstract: [Problem] In conventional vehicle lamp devices, exit light exits from stepped partition surfaces without having been subjected to light distribution control. [Solution] The present invention is provided with a lens, and a semiconductor-type light source. The lens is configured from one incidence surface, and nine exit surfaces partitioned by stepped partition surfaces. Among the nine exit surfaces, lower exit surfaces are positioned further towards a side in the exiting direction of light than upper exit surfaces. As a result, in the present invention, exit light exiting from horizontal stepped partition surfaces is subjected to light distribution control by the horizontal stepped partition surfaces which are downwardly inclined from above, is retracted downwards to the optical axis of the lens, and exits.

  • Patent number: 8287165
    Abstract: A conventional vehicle lighting device entails difficulty in smoothly dimming a part at a downside of a cutoff line of a light distribution pattern. A shade-cum additional reflector includes a cutoff line forming portion which forms an opposite lane side cutoff line, an oblique cutoff line, and a cruising lane side cutoff line, of a light distribution pattern for passing, i.e., a horizontal portion, an inclined portion, and a corner portion, of a protrusion. Of an additional reflecting surface, in proximal to at least the horizontal portion of the protrusion, a spherical convex portion is provided as a diffusion portion for diffusing and reflecting a part of the cut off reflected light onto a side of a projecting lens. As a result, a lighting device of the present invention allows for smooth dimming of a part at a downside of at least the opposite lane side cutoff line, of a light distribution pattern for passing.
