A rear light is a light disposed in a rear portion of a vehicle, and includes: a light source; a light-transmitting plate that guides incident light from the light source; and a dot portion that is disposed on the light-transmitting plate and reflects incident light to the outside of the vehicle with different reflection intensities depending on positions on the light-transmitting plate.

Vehicle light

A vehicle lighting fixture includes: a light source; an outer lens disposed in front of the light source; a heat sink thermally connected to the light source; and an air blower having air blowing openings behind the light source. The heat sink includes: a base portion extending outward, relative to the light source, in an intersection direction intersecting with an optical axis of the light source; and a heat dissipation portion extending longitudinally from an outer portion of the base portion in the intersection direction, dissipating heat to the air blown from the air blowing openings, and directing the air to the outer lens.

Lighting fixture for vehicle

Provided is a vehicular illumination device including a light emitting portion mounted on a headlight, and capable of outputting light from the light emitting portion forwardly of a vehicle with enhanced design and enhanced visibility. An illumination device is provided on a front portion of a vehicle, and includes a headlight, a light guide, and an outer glass. The outer glass is configured such that a perimeter portion and a front surface portion are integrally formed. The perimeter portion includes an incident portion on a middle portion in a length direction of the light guide, the incident portion allowing incidence of light output from the light guide. The light guide is disposed in proximate to the incident portion. Light incident from the light guide to the perimeter portion is guided forwardly, while repeating reflection on inner and outer circumferential surfaces of the perimeter portion, and output forwardly from an output portion formed on the front side.

Vehicular illumination device

Provided is a vehicular illumination device capable of increasing a degree of design freedom in designing a vehicle having enhanced design. An illumination device is provided on a front portion of a vehicle. The illumination device includes a headlight, a light guide, and an outer glass. The light guide has an annular shape in such a way as to surround a periphery of the headlight. The outer glass includes a front surface portion for covering a front surface of the headlight, and a perimeter portion for covering a periphery of the headlight. The light guide is disposed along an imaginary plane inclined with respect to a tubular axis of the perimeter portion.

A vehicle headlight control device is provided with: a pedestrian detection unit which detects a pedestrian; and a headlight control unit which controls an irradiation state of a headlight. When the pedestrian detection unit detects a pedestrian within an irradiation range of the headlight, the headlight control unit executes dimming control for controlling the irradiation state of the headlight so that a periphery of the pedestrian is dimmed. The pedestrian is irradiated with a part of a high beam or a low beam, or marking light emitted from a dedicated light source. A dimming region is formed around the pedestrian by the dimming control, and contrast in brightness between the pedestrian and his/her surroundings can be raised.
