A light distribution pattern is emitted with appropriate illuminance. A vehicle light-guiding body has an incident surface; a first reflection surface; a second reflection surface; a light shielding portion; an internal reflection surface located between a front-side end part of the second reflection surface and the light shielding portion and internally reflects, to a front, a part of the light internally reflected by the second reflection surface; an emission surface; and an adjustment portion provided at a part which is a rear of the light shielding portion in the internal reflection surface and closer to one of right and left than the focal point of the second reflection surface and emits a part of the light reflected by the second reflection surface from a part different from the emission surface to an outside by internally reflecting or refracting a part of the light reflected by the second reflection surface.

Vehicle light-guiding body and vehicle lighting unit

A vehicle lighting appliance lens, a vehicle lighting appliance unit, and a vehicle lighting appliance device each includes an incidence part, a second reflective surface, a cutoff-line forming part, and an emission surface. The cutoff-line forming part is provided in the left-right direction of a vehicle. As a result, the flowability of resin is improved, the control of a low-beam light distribution pattern is improved, and a cutoff line without warping is formed.

Vehicle lighting appliance lens, vehicle lighting appliance unit, and vehicle lighting appliance device

A vehicle light guide body includes an incident surface that light from the light source enters, a first reflective surface that internally reflects the light that has entered from the incident surface to form nearly parallel light, a second reflective surface that internally reflects the light from the first reflective surface, a third reflective surface provided in a position located in front of the second reflective surface in a front-rear direction and in a portion in at least one of end faces in a left-right direction, a light shielding part that shields a part of the light reflected by the second reflective surface, and a light emitting surface that emits the light that has been internally reflected by the second reflective surface and has passed through the light shielding part to illuminate a headlight pattern in front of a vehicle.

Vehicle light guide body and vehicle lighting unit

A vehicular light guiding body and a vehicular lam unit are configured to perform fine light distribution control. The vehicular light guiding body includes an incidence surface on which light from a light source is incident, a first reflection surface that internally reflects the light incident from the incidence surface, a second reflection surface that has a shape based on a paraboloid of revolution which reflects substantially parallel light from the first reflection surface toward a focus point, a light blocking part that blocks a portion of the light reflected by the second reflection surface, and an emission surface that emits the light internally reflected by the second reflection surface to pass through the light blocking part and that projects a headlight pattern toward a front of a vehicle.

Vehicular light guiding body and vehicular lamp unit

The present invention is provided with a first lamp unitand a second lamp unit. The first lamp unitis provided with a semiconductor-type light source, a reflector, a shade, and a driving mechanism. The reflectorhas a first reflection surfaceand a second reflection surface. The first reflection surfaceis adapted to emit lateral light distribution patterns CPL and CPR. The second reflection surfaceis adapted to emit a light distribution pattern HP for high beam. As a result, according to the present invention, it becomes possible to obtain an arbitrary auxiliary light distribution pattern, such as a light distortion pattern for spot or a light distribution pattern for scattering other than the lateral light distribution patterns CPL and CPR.
