Abstract
A vehicle headlamp 10 is provided with an upper stage light source unit 20, a middle stage light source unit 40, a lower stage light source unit 60. The upper stage light source unit 20, the middle stage light source unit 40, the lower stage light source unit 60 are provided at a lamp body 14 constituting a lamp member by way of a support member 15, and a light distribution pattern for low beam is formed on a front side of a vehicle by overlapping light from the respective light source units 20, 40, 60. The middle stage light source unit 40 is supported to be able to change the optical axis independently from the other light source units 20, 60.
Claims10
A vehicle headlamp comprising:
- a plurality of light source units, each light source unit including a light source and an optical member for irradiating light from the light source along an optical axis;
- and
- a lamp member that supports the plurality of light source units, wherein a light distribution pattern for a low beam is formed on a front side of a vehicle by overlapping lights from the respective light source units;
- wherein at least one of the plurality of light source units is an optical axis variable light source unit supported by the lamp member so as to be able to change the optical axis independently from the other optical axes of the other light source units.
A vehicle headlamp comprising:

- and
- a lamp member that supports the plurality of light source units, wherein a light distribution pattern for a low beam is formed on a front side of a vehicle by overlapping lights from the respective light source units;
- wherein at least one of the plurality of light source units is an optical axis variable light source unit pivotably supported by the lamp member to move the optical axis substantially along a horizontal face;
- wherein the optical axis variable light source unit is provided with a diverging member for diverging light emitted from the light source between the projecting lens and the light source;
- and
- wherein light is diverged by the diverging member when the optical axis variable light source unit is pivoted and the optical axis is moved to irradiate light to a side of the front side of the vehicle from a position of irradiating light from a center of the front side of the vehicle.
