Abstract
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.
