A vehicle lamp includes a projection lens, a first light source disposed behind the projection lens and configured to emit light forming a low-beam light distribution pattern which is a predetermined light distribution pattern, a reflector configured to reflect light emitted from the first light source toward a first rear focal point of the projection lens, and a second array light source disposed behind the projection lens and having a plurality of semiconductor light emitting elements arranged in at least one row. The second array light source is configured to emit light forming an additional light distribution pattern, and the center position or maximum light intensity position of the additional light distribution pattern overlaps with the low-beam light distribution pattern on a virtual vertical screen in front of the lamp.

Vehicle lamp

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.
