PURPOSE: A three-mode integrated headlamp is provided to reduce the production cost of the lighting system by easily changing the light emitting system. CONSTITUTION: A three-mode integrated headlamp is a head lamp for vehicle lighting system(100), and includes a discharge light source, a reflector, and a shutter. The reflector guides the light received from the light source to the outer side as the light ray. The shutter is mobile for the change over between the high beam mode and the downstream light ray mode about the reflector. The divergence change units(180,182) change the emissive power of the light ray between the downward/upward modes and a daytime driving illumination(DRL) mode.
