Abstract
A vehicle headlamp according to the present invention is provided with: a semiconductor-type light source 5U; a reflector 3; a holder 6; a mount member 70U; and a light shading member 12U which has first additional reflection surfaces 15U, 15U as optical members. The mount member 70U and the light shading member 12U that has the first additional reflection surfaces 15U, 15U form an integrated structure. As a result, the vehicle headlamp according to the present invention is capable of mutually mounting, with high precision, a semiconductor-type light source 5U and the light shading member 12U that has the first additional reflection surfaces 15U, 15U as the optical members.
Claims10
A vehicle headlamp employing a semiconductor-type light source as a light source, said headlamp comprising:
- the semiconductor-type light source having a light emitting chip;
- a reflector having a reflection surface configured to reflect light from the light emitting chip and to then emit the reflected light forward of a vehicle as a predetermined light distribution pattern;
- a holding member configured to hold the reflector and on which the semiconductor-type light source is disposed;
- a mount member that mounts the semiconductor-type light source on the holding member, the mount member being arranged above the holding member;
- and
- an optical member configured to optically process light directly radiated from the light emitting chip forward of the vehicle, the optical member being configured to shade a part of the light directly radiated, and the optical member being arranged above the mount member, wherein:
- the mount member and the optical member form an integrated structure such that the entire optical member is directly arranged above the mount member,
- the vehicle headlamp further comprises a fixing portion that fixes the mount member forming the integrated structure with the optical member to a surface of the holding member on which the semiconductor-type light source is disposed,
- the entire optical member is arranged above the holding member, and
- the semiconductor-type light source is mounted to the holding member via the mount member by fixing the mount member to the holding member with the fixing portion.
