A projection lens has a first lens body including a first incidence section disposed at a side facing a first light source and a first emitting section disposed at a side opposite to the first incidence section, and a second lens body including a second incidence section disposed at a side facing a second light source and a second emitting section disposed at a side opposite to the second incidence section, a structure in which the first lens body and the second lens body abut against each other via an intermediate layer which is interposed between facing boundary surfaces of the first lens body and the second lens body is provided, and a refractive index of the intermediate layer is smaller than a refractive index of the first lens body.

A headlamp control system includes: a headlamp that emits light toward a forward direction of a vehicle; a tilt detection part; and a control part. The headlamp includes: high beam emitting parts that respectively illuminate plural high beam areas arrayed in a left-right direction; and a low beam emitting part that illuminates a low beam area located at a lower position than the plural high beam areas. The control part, in a state where the low beam emitting part is on, when the tilt detection part detects that the vehicle has tilted such that one of left and right sides of the vehicle is lowered than the other one of the left and right sides, controls the high beam emitting parts so as to illuminate at least one of the plural high beam areas, the at least one being on the one of the left and right sides.

A lamp for a vehicle is provided that can include a housing, an axial symmetric lens coupled to the housing and defining an optical axis and a focal point, an image shifting lens positioned within the housing behind the axial symmetric lens relative to the optical axis, and a light source positioned within the housing. The light source can be positioned behind the image shifting lens. The light source can be configured to emit light along an optical path that extends, from the light source, through the image shifting lens, towards the axial symmetric lens above the optical axis, and through the axial symmetric lens to define a high beam illumination pattern.

A light device is configured to generate a plurality of beam pattern images in which various images of light emitted from a plurality of fine light emitters are projected through fine lenses and shields, whereby various images of light are projected in accordance with whether the fine light emitters are turned on. Further, a light source array, a shield array, and a lens array are each formed in a plate shape, so the size decreases and the structure is simplified.

A light system comprising: (a) a plurality of light sources connected to a vehicle and creating light that radiates away from the vehicle so that the light substantially surrounds the vehicle; and (b) one or more sensors that detect light from another light source; and wherein one or more of the plurality of light sources are turned off in a direction of the another light source while some of the plurality of light sources remain on so that a tunnel having a reduction or absence of light is formed in the direction of the another light source between the plurality of light sources that remain on.

A method for correcting a first light pattern provided by a lighting device with a matrix of light sources. The method includes steps of providing some resolution data of the light sources, simulating a test map of the light pattern using the resolution data, and simulating distortion maps of the test map. Each distortion map is associated to a distortion factor. Also included is obtaining a real distorted light pattern, comparing the real distorted light pattern with the distortion maps, finding a distortion map which is the most similar to the real distorted map and applying a correction factor to correct the real distorted light pattern, thus obtaining a corrected light pattern. The correction factor is related to the distortion factor of the distortion map which is the most similar to the real distorted map.
