Headlamp for vehicle

摘要

A headlamp having a plurality of lighting units using light emitting diodes as light sources. A cutoff line forming unit, hot zone forming units, and a diffusion region forming unit are used as these lighting units. Consequently, a light distribution pattern for a low beam having a desirable pattern shape and light intensity distribution can be obtained as the synthetic light distribution pattern of light distribution patterns formed by the irradiation of a light from these three kinds of lighting units.
