Abstract: 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.

Abstract: 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.

Abstract: A vehicular light-guiding body includes: an incidence surface on which light from a light source is incident; a first reflection surface; a second reflection surface; a connecting surface that has a transmission surface which transmits a portion of the light reflected by the second reflection surface from a lower side in an up-down direction on the onboard state to a guiding body outer part, and directs the light forward in the front-rear direction; a re-incidence surface that is disposed on a front side in the front-rear direction with respect to the transmission surface and on a lower side in the up-down direction with respect to the light blocking part, and allows the light transmitted from the transmission surface to the guiding body outer part to be re-incident; and an emission surface that emits the light internally reflected by the second reflection surface, and the light incident from the re-incidence surface.

Abstract: The present invention is provided with a first lamp unit 4 and a second lamp unit 5. The first lamp unit 4 is provided with a semiconductor-type light source 14, a reflector 15, a shade 16, and a driving mechanism 17. The reflector 15 has a first reflection surface 21 and a second reflection surface 22. The first reflection surface 21 is adapted to emit lateral light distribution patterns CPL and CPR. The second reflection surface 22 is 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.

Abstract: A vehicle lighting device is provided in such a manner that a reflector and a light source are incorporated in a lamp room made of a housing and a front lens. The light source is disposed so that an emission direction of light from a light emission surface of the light source crosses an optical axis of the front lens. The reflector is disposed on one side with respect to a surface on which the light source is to be disposed, the reflector being configured with a curved portion that is adapted to reflect the light from the light source to a side of the front lens. A coloring member is disposed so as to be adjacent to at least a part of the periphery of the light emission surface of the light source.
