Vehicle headlight
An ADB lamp unit of a vehicle headlamp includes a light source constituted by a plurality of semiconductor light-emitting elements that can be turned on/off individually, and a reflector having a reflective surface that is based on a paraboloid of revolution. The reflector is constituted by a perpendicularly split plurality of partial reflectors, with the reflective surface of each partial reflector being configured such that the horizontal spread of reflected light reflected by each partial reflectors is approximately equal in a predetermined projection plane.
