Abstract: A vehicle headlamp includes a plurality of light emitting elements; a plurality of first lenses; and a plurality of second lenses. The first lens includes a first lens entrance and a first lens exit, and is configured to converge light entered the first lens entrance from the light emitting element on the first lens exit. The second lens includes a second lens entrance facing the first lens exit of the first lens and the second lens exit having a projection shape for forming a focal point. The focal point of the second lens is positioned at a side of the second lens ahead the first lens exit of the first lens.

Abstract: A headlight for a vehicle having good heat dissipation performance includes a plurality of lens units, each including a plurality of light emitting devices, and lenses arranged so as to face the respective plural light emitting devices. The plurality of light emitting devices include first light emitting devices arranged on an inner side of the vehicle and having a first light emitting area and second light emitting devices arranged on an outer side of the vehicle having a second light emitting area. A first light distribution emitted from first lens units having the first light emitting devices and a second light distribution emitted from second lens units having the second light emitting devices are included, and the second light emitting area is smaller than the first light emitting area as well as a range of the second light distribution is smaller than a range of the first light distribution.
