Abstract
A reflector reflects a light from a light source. A projector lens projects a reflected light from the reflector ahead of a vehicle. A shade is used to switch the reflected light into a plurality of beams in a plurality of light distribution patterns. A spring member and a drive unit switch a position of the shade between an obliquely upward and backward position and an obliquely downward and forward position to obtain the light distribution patterns.
Claims8
A projector-type vehicle headlamp capable of obtaining a plurality of light distribution patterns, comprising:
- a light source that emits a light;
- a reflector that reflects the light from the light source;
- a projector lens that projects a reflected light from the reflector ahead of a vehicle;
- a shade that is used to switch the reflected light into a plurality of beams in a plurality of light distribution patterns;
- and
- a switching unit that switches a position of the shade between an obliquely upward and backward position and an obliquely downward and forward position to obtain the light distribution patterns, the switching unit including a spring member and a drive unit,
- wherein the drive unit includes a solenoid with a retractable rod, a direction in which the retractable rod moves is identical to a direction in which the shade is switched between the obliquely upward and backward position and the obliquely downward and forward position, and the solenoid is arranged obliquely downward and forward from the shade in an opposite side of the light source.

- and
- a switching unit that switches a position of the shade between an obliquely upward and backward position and an obliquely downward and forward position to obtain the light distribution patterns, the switching unit including a spring member and a drive unit,
- wherein
- the spring member has a dome shape,
- the shade is integrated with the spring member,
- a direction in which a spring force of the spring member acts is identical to a direction in which the shade is switched between the obliquely upward and backward position and the obliquely downward and forward position, and
- the spring member is sandwiched and fixed between the drive unit and a frame member to which the drive unit is fixed.
