A vehicle headlight includes: an image generation unit; a light source unit configured to emit light based on an image generated by the image generation unit; and a memory configured to store a reference image for forming a reference light distribution pattern and a plurality of additional images, in which each of the plurality of additional images is one of a plurality of darkened images, and a plurality of brightened images, and the image generation unit generates the image for forming a predetermined light distribution pattern by light emitted from the light source unit by selecting at least one additional image and superimposing the selected additional image on a part of the reference image, the predetermined light distribution pattern being obtained by changing an amount of light of a predetermined region overlapping a predetermined target object in the reference light distribution pattern.

Vehicle headlight having an imaging generation unit and a matrix light source unit for producing overlapping images in a light distribution

A vehicle lamp according to an aspect of the present invention includes a light source, a metal light-source stage including a light-source mounting portion, and a lens member that emits light from the light source toward the front of the lamp. The light-source stage includes a support portion for the lens member. The lens member includes a leg projecting toward the light-source stage and having an end that is supported by the support portion. The support portion includes three projections that abut the leg in a state in which the leg is supported by the support portion and position the lens member in a direction of an optical axis. The three projections are positioned relative to one another such that at least a portion of the light source lies in an extension range of a triangle with vertices given by the three projections.

Vehicle lamp

A discharge lamp device for a vehicle includes a lighting circuit for performing lighting controls of a discharge lamp for high beam and a discharge lamp for low beam, both lamps having the same rating. The lighting circuit controls the power supply such that the electrical power input when the discharge lamp for high beam is lighted is greater than the electrical power input when the discharge lamp for low beam is lighted.

Discharge lamp device for vehicle

A lighting system provides an auxiliary lighting circuit for turning on an auxiliary light source in place of the discharge lamp if the abnormality in the lighting circuit is detected.

Lighting system for vehicle

A steady-state condition in which respective discharge lamps for main beam and for dipped beam are both turned on, a sum (P &plus;P ) of a value of power supplied to each discharge lamp is controlled to be smaller than a sum (P R&plus;P R) of a rated power value for each discharge lamp.
