Lamp unit and vehicle headlamp
A lamp unit includes a light-emitting element array composed by a plurality of light-emitting elements, having respective individual irradiation regions constituting a high-beam light-distribution pattern and configured to be capable of being turned on individually, mounted in array on a substrate, a projection lens disposed in front of the light-emitting element array, and a reflector disposed below the light-emitting element array. Inter-light-emitting-element spacing within the light-emitting element array widens the more separated the elements are from the projection lens' optical axis.
Vehicular lighting
The objective of the invention is to provide vehicular lighting such that unevenness in the light distribution occurring on a road surface is minimized upon consideration of workability when performing an adjustment by aiming, or the like. This vehicular lighting forms a light distribution having a cut-off line CL, and comprises a light source (30) and a lens (50) disposed on the forward side of the light source (30). The entry surface (51) of the lens (50) wherefrom light from the light source (30) enters comprises: an upper side entry surface (54) on an upper side from the center of the entry surface (51), wherein first light diffusing portions (54a) for diffusing the light are disposed; a lower side entry surface (56) on a lower side from the center of the entry surface (51), wherein second light diffusing portions (56) for diffusing the light are disposed; and a middle entry surface (55) including the center of the entry surface, wherein third light diffusing portions (55b) and fourth light diffusing portions (55a) for diffusing the light are disposed, and having straight-through portions (55c) wherein no third light diffusing portions (55b) and no fourth light diffusing portions (55a) are disposed. The light diffusion width for each of the third light diffusing portions (55b) is larger than the light diffusion width for each of the fourth light diffusing portions (55a).

Vehicular headlamp
A vehicular headlamp includes a light source on which a light emitting diode is mounted on a substrate, a heat spreading plate attached to the substrate so as to be capable of transferring heat, a holding member integrated with the heat spreading plate, a heat pipe comprising a first end portion and a second end portion, each of which having a circular cross-section, the first end portion being rotatably engaged with the holding member, and a heat sink connected to the second end portion.

Lens assembly for implementing low beam
A lens assembly for implementing a low beam may include: a first lens including an incident surface having a shape enclosing a light emitting diode (LED), and an exit surface through which light of the LED exits in a direction perpendicular to the exit surface; and a second lens disposed on the exit surface of the first lens and configured to project the light of the LED that exits from the exit surface. The light of the LED that is projected through the second lens may form a low-beam pattern.

VEHICLE HEADLAMP
A light emitting element, a reflector, a projection lens, and a movable shade are arranged in a lamp chamber. As the movable shade is erected, a low beam is formed. As the movable shade is tilted, a travelling beam is formed. The reflector and a sub reflector are integrally formed. The movable reflector reflects the reflected light reflected by the sub reflector toward the projection lens. The sub reflector is positioned in a range of an outer shape of the projection lens.
Vehicle light assembly
A low profile light assembly for a vehicle. The assembly includes a first lens having an outer profile that provides a portion of an external profile of the vehicle. The assembly also includes a second lens disposed on a side of the first lens that is opposite the outer profile. The light assembly also includes a light curtain that includes a first side that corresponds to a portion of an inner profile of the second lens and a second side, opposite the first side, that includes protrusions evenly spaced along a length of the second side, the protrusions include a first surface that extends a width of the second side. The assembly also includes at least one light source that is directed toward at least some of the first surfaces of the protrusions.
