An object of the present invention is to provide a lamp unit for a vehicular headlamp and a vehicular headlamp, by which it is possible to diffuse left and right ends of a high-beam light distribution pattern further to the left and right. An inner reflecting surface reflects light from a first light-emitting element as reflected light onto a lens. The lens emits the reflected light in a diffused light distribution pattern toward a front of a vehicle. An edge of a diffused light distribution pattern on an outer side of the vehicle is located further to an outer side of the vehicle than an edge of a first partial light distribution pattern on the outer side of the vehicle. As a result, left and right ends of an overall high-beam light distribution pattern can be diffused further to the left and right.

Lamp unit for vehicular headlamp, and vehicular headlamp

Provided is a vehicle lamp which forms a travel light distribution pattern in which occurrence of a dark area between low and high beam light distributions is suppressed. A projection lens is divided into a plurality of lens areas, each of which has a different focal point position, and one second lens area is a low lens area. A low beam light source module is set such reflected light from the reflector is incident on a back surface of the second lens area, and a low beam light distribution is emitted from an area front surface. A high beam light source module is set such that emitted light from a high beam light source is directly incident on a lens back surface of the projection lens, and a high beam light distribution for each area is emitted from each of a plurality of area front surfaces.

Vehicle lamp

A vehicular headlamp includes a first light source for emitting a first light forward; a second light source disposed above the first light source and for emitting a second light forward; a first reflecting surface disposed in front of the first light source for reflecting the first light upward; a second reflecting surface disposed above the second light source for reflecting forward the first light reflected by the first reflecting surface; a third reflecting surface disposed above the second light source and below the second reflecting surface, is connected to the second reflecting surface, for reflecting the second light forward; and a projection lens disposed in front of the first, second, and third reflecting surfaces. The first and second light sources disposed on the same plane.

Vehicular headlamp with coplanar low-beam and high-beam light sources

Provided is a vehicular lamp that forms a light distribution pattern for traveling having a lower end portion overlapping an upper end portion of a light distribution pattern for passing and is downsized with a simple configuration. The vehicular lamp includes a projection lens that projects light emitted from a first light source to form the light distribution pattern for passing and projects light emitted from a second light source to form the light distribution pattern for traveling. A lower lens part and an upper lens part are set in the projection lens about a lens axis as a center, a lower focus is set on the lens axis in the lower lens part, and an upper focus shorter in focal length than the lower focus is set on the lens axis in the upper lens part.
