Abstract: A vehicle lighting unit can include at least one optical module including: first and second light sources; first and second optical member configured to control light from the first and second light sources, respectively; and an outer peripheral optical member configured to surround the first optical member. The first optical member can include an incident surface, and front and rear surfaces and receive light from the first light source through the incident surface and reflect the light by part of the front surface and then part of the rear surface to project the reflected light through part of the front surface. The second optical member is configured to guide the light from the second light source to the outer peripheral optical member so that the light exits through the outer peripheral optical member, and the second light source, and the second optical member are disposed behind the first optical member.

Abstract: A projector type headlight can include a projection lens arranged on an optical axis extending in a longitudinal direction of a vehicle, and a light source unit arranged on a more rear side than a back side focal plane of the projection lens, the projection lens including resin lenses which are arranged on the optical axis. A resin lens out of the resin lenses arranged closer to the light source unit includes a diffraction grating provided on a lens face in a side opposite to a light source, the resin lens out of the resin lenses arranged closer to the light source unit has a lens face having a positive power, which is arranged in a light source side, and the diffraction grating is designed so as to cancel chromatic aberration of light emitted from the light source unit and emitted forward through the resin lenses.

Abstract: A vehicle lighting unit can form a structure or mechanism for positioning and installing a light emitting device in a vehicle lighting unit main body.

Abstract: A vehicle light is capable of preventing gaps (areas darker than peripheral areas) from being formed in between a plurality of illumination areas that are independently controlled to be illuminated with light or not to be illuminated with light, or suppressing the generation of such gaps. The vehicle light can include a projection lens and a light source unit disposed behind the rear-side focal plane of the projection lens. The light source unit can include a plurality of tubular portions each having a reflective inner peripheral surface, and a plurality of semiconductor light emitting elements. Exit openings of the plurality of tubular portions can be arranged side by side in a substantial horizontal direction behind the rear-side focal plane of the projection lens. Adjacent ones of the plurality of exit openings of the tubular portions can be defined and partitioned by a common vertical edge.
