A vehicle lamp, which is capable of partially adjusting the light distribution, includes a light source unit including a plurality of light-emitting elements, a lens provided in front of the light source unit, and a reflective surface provided below the plurality of light-emitting elements and between the light source unit and the lens. An inclination angle of a first reflective surface, which is a partial region of the reflective surface in a vehicle width direction, with respect to the lens optical axis is smaller than that of an adjacent region that is adjacent to the first reflective surface in the vehicle width direction.

A lamp unit that can form an illumination pattern near a vehicle is provided without increasing the vertical dimension. A vehicle lamp using the same is also provided. A lamp unit includes, an installation base unit with light sources, a converging lens that converges light from the light sources, a light blocking member with slit units allowing partial passage of the light converged by the converging lens, and a projection lens that projects the light delivered through the light blocking member, to form an illumination pattern having illumination figures, which are arranged along a lamp unit axis. The projection lens and light blocking member are rotated downward about a reference focal point set on the lamp unit axis, and the installation base unit and converging lens are rotated downward about an installation base unit reference point set behind and above the reference focal point.

Provided is a vehicle lighting fixture capable of achieving a three-dimensional appearance, and a lighting fixture unit capable of emitting light having uniform brightness. The vehicle lighting fixture includes: a light-emitting body; an inner lens that emits light from the light-emitting body to at least a front side; and a light-transmitting member positioned away from the inner lens, and provided with a light-blocking pattern that blocks a portion of the light from the inner lens. The lighting fixture unit includes: an annular light-guiding body having incident surfaces on the left and right sides formed facing outward in a left-right direction at locations each vertically offset from a central axis, and guides and emits light incident from the incident surfaces to the front side; and an inner lens disposed on the front side along the annular light-guiding body that emits light from the annular light-guiding body to the front side.

To assist a driver of another vehicle attempting to pass in front of a host vehicle in recognizing the distance to the host vehicle and the time until the host vehicle approaches. A control ECU controlling a display operation of a display medium that is mounted in a vehicle and displays information toward a traveling direction of the vehicle recognizes, based on a recognition result of an external sensor mounted in the vehicle, a distance between the vehicle and another vehicle present in the traveling direction of the vehicle, causes the display medium to display distance information used for announcing the recognized distance between the vehicle and the other vehicle, and changes the distance information displayed on the display medium in accordance with a change in the recognized distance between the vehicle and the other vehicle.

The invention is to irradiate a light distribution pattern with an appropriate illuminance. A vehicle light-guiding body includes an incidence surface, a first reflection surface internally reflecting incident light, a second reflection surface internally reflecting the light reflected by the first reflection surface forward, a light blocking part blocking a portion of the light reflected by the second reflection surface, an adjustment surface extending forward from a front side end of the second reflection surface, a transmission surface provided in a state of extending upward in an up-down direction from the front side end of the adjustment surface and transmitting a portion of light reflected by the second reflection surface to a light-guiding body outer part, a connection surface connecting the transmission surface and the light blocking part, and internally reflecting a portion of the light internally reflected by the second reflection surface, a re-incidence surface, and an emission surface.

The vehicle lamp includes a first reflector portion forming a first light distribution pattern having a cutoff line by light from a first light source, a second reflector portion forming a second light distribution pattern forming at least a part of a low-beam light distribution pattern by light from a second light source, and a third reflector portion forming a third light distribution pattern by light from a third light source. The first reflector portion and the second reflector portion are provided adjacent to each other in a width direction on an attachment surface of an attachment member, and the third reflector portion is provided between the first reflector portion and the second reflector portion in the width direction and on the front side of the first reflector portion and the second reflector portion on the attachment surface.

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.

A lighting fixture for a vehicle efficiently releases heat from a light source while inhibiting moisture from entering the light source side. The lighting fixture includes: a light source; a heat dissipating member which dissipates heat from the light source, the light source being placed on an installation surface of the heat dissipating member; and a socket to which the heat dissipating member is attached. The heat dissipating member has a heat dissipating fin part protruding from a heat dissipating surface on the side opposite to the installation surface, and a heat dissipating-side positioning part (positioning projection) provided on the heat dissipating surface. The socket has, on an attachment surface, a fin recess into which the heat dissipating fin part fits, and a socket-side positioning part (positioning hole) which determines the positional relationship between the heat dissipating member and the socket in cooperation with the heat dissipating-side positioning part.

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.
