发明名称 VEHICLE HEADLAMP
摘要 PROBLEM TO BE SOLVED: To provide a vehicle headlamp which can form a light distribution pattern high in visibility.SOLUTION: A vehicle headlamp comprises: a projection lens; a first optical system 21 having a first reflector 32 for reflecting light from a first light source 31 in a direction approaching an optical axis Ax; a second optical system 35 having a second reflector 36 for reflecting light from a second light source 35 in a direction approaching the optical axis Ax; and a transparent member 23 arranged in the vicinity of a rear focus point f of the projection lens. The projection lens forms a low-beam light distribution pattern by emitting the light from the first optical system 21 to the front of the lamp, and the transparent member 23 has a vapor deposition film 24a for forming a cutoff line of the low-beam light distribution pattern by reflecting a part of the light from the first optical system 21, and a lens part 25 which refracts at least a part of the light from the second optical system 22, and irradiates an upper irradiation region including at least a part of the cutoff line of the low-beam light distribution pattern with light.
