A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.

A lamp device for vehicle 1 comprises a light source 2, an inner lens 3 configured to accept light of the light source 2, and a housing 5 configured to cover a periphery of the light source unit 2 and the inner lens 3. When a traveling direction of a light beam with a largest light amount in the light emitted from the light source 2 is defined as front, the housing 5 includes a back surface portion 51 located on a rear side of the inner lens 3, and a lower surface portion 53 located on a lower side of the inner lens 3, the lower surface portion 53 includes an extended portion 53a extended to a front side of a front surface portion 31a of the inner lens 3.

A lighting device capable of illuminating an entire region of a region to be illuminated with uniform brightness and with a desired color is provided. Provided is a lighting device that extends in a first direction and illuminates a region to be illuminated that extends in a second direction intersecting with the first direction includes a light source that emits coherent light, and a plurality of hologram components each of which diffracts the coherent light emitted by the light source to illuminate the entire region of the region to be illuminated. At least one of the plurality of hologram components diffracts the incident coherent light so that illuminance at both end portions in the second direction of the region to be illuminated is higher than the illuminance at the central portion.

A substrate supports a light source and a control circuit. The control circuit is configured to be able to control lighting and lights-out of the light source. The substrate is supported to a conductive housing. The housing is configured to couple with a transparent cover through which light emitted from the light source is to pass.

A vehicular lighting fixture is a vehicular lighting fixture configured to illuminate a side in front of a vehicle, and includes a parallel light illumination device configured to emit parallel light and a projection optical system configured to project the parallel light emitted from the parallel light illumination device to a forward side, and in the projection optical system, a focal length of a horizontal component is smaller than a focal length of a vertical component.

A headlight module includes a light source, a light distribution control element and a projection optical element. The light source emits light. The light distribution control element forms a light distribution pattern by changing a divergence angle of the light incident therein.
