    摘要： A vehicle headlight (1), which is one aspect of a vehicle illumination lamp, includes: light sources (52R, 52G, 52B), and diffraction gratings (54R, 54G, 54B) for diffracting light incident from the light sources (52R, 52G, 52B). The light diffracted by the diffraction gratings (54R, 54G, 54B) is irradiated in a predetermined light distribution pattern. A projection area (AR) to which are projected components (LC R , LC G , LC B ) advancing and passing through the diffraction gratings (54R, 54G, 54B) among the light incident on the diffraction gratings (54R, 54G, 54B) is positioned below the light distribution pattern and within a range (RNG) in which a field of view of a driver of a vehicle is obstructed by the vehicle.

    摘要： A good light distribution pattern at both times of high beam lighting and low beam lighting is realized for a vehicle lamp that performs lighting switching of a high beam and a low beam by light emission and non-light emission of a lower side light emitting area in a light emitting unit in which a plurality of light emitting elements are arranged in a matrix.
    The vehicle lamp according to the present invention includes a light emitting unit in which a plurality of light emitting elements are arranged in a matrix, a projection lens which is configured to focus and project light emitted from the light emitting unit, a light emission drive unit which is configured to drive the light emitting element to emit light based on an input voltage from an in-vehicle battery, and a control unit which is configured to perform control to cause both a lower side light emitting area and an upper side light emitting area located above the lower side light emitting area to emit light in response to a high beam lighting instruction and to cause the lower side light emitting area not to emit light in response to a low beam lighting instruction. The control unit is configured to perform control to vary light amount distribution of the upper side light emitting area at a time of high beam lighting and a time of low beam lighting.

    摘要： A vehicle lamp includes a light source, and an aberration correction lens unit, that corrects chromatic aberration, irradiates in a frontward direction with direct light from the light source. The aberration correction lens unit includes a first lens located in a front side of the light source, and a second lens located in front of the first lens. The aberration correction lens unit performs vibration control for vibrating intersections in a front-back direction. The intersections are intersections of an optical axis, and red, green, and blue components of white light incident in parallel from the front toward the outside in the radial direction from the optical axis side of the aberration correction lens unit.

    摘要： Vorgestellt wird ein Lichtmodul für einen Kraftfahrzeugscheinwerfer mit n in einer Reihe nebeneinander angeordneten Teillichtmodulen, von denen jedes i-te Teillichtmodul der i = 1 bis n Teillichtmodule eine i-te Lichtquelle, eine der i-ten Lichtquelle zugeordnete i-te Primäroptik und eine der i-ten Lichtquelle zugeordnete i-te Sekundäroptik aufweist, wobei jedes Teillichtmodul dazu eingerichtet ist, einen zentralen Raumwinkelbereich zu beleuchten. Das Lichtmodule zeichnet sich dadurch aus, das die Primäroptik von jedem der n Teillichtmodule dazu eingerichtet und angeordnet ist, einen Teil des von der Lichtquelle dieses Teilmoduls ausgehenden Lichtes an dessen Sekundäroptik vorbei so auf eine Sekundäroptik eines nächst benachbarten Teillichtmoduls zu richten, dass das nächstbenachbarte Teillichtmodul mit diesem Licht einen peripheren Raumwinkelbereich beleuchtet, der sich mit dem zentralen Raumwinkelbereich durchdringt und der dabei über den zentralen Raumwinkelbereich seitlich herausragt.

    摘要： A lamp unit includes a light source including a first light emitting element that emits visible light and a second light emitting element that emits infrared light, and a rotating reflector that rotates about a rotational axis while reflecting visible light and infrared light emitted from the light source. The light source is configured such that part of the second light distribution pattern overlaps with the first light distribution pattern and such that a region of the second light distribution pattern, which does not overlap with the first light distribution pattern, is provided on the side closer to a middle region in front of the vehicle with respect to the first light distribution pattern.
