A light projecting lens 14 is disposed opposite to the reflecting surface 11a so as to have the same optical axis as the reflecting surface 11a, and a light shielding plate 14 is interposed between the reflecting plate 11 and the light projecting lens 13. The light source 12 is installed at a first focal point F1 located in the reflecting surface 11a, and the light shielding plate 14 is connected to the second focal point F1 of the reflecting surface 11a.
At the position coinciding with 2, the distal end is installed below the optical axis at a predetermined distance from the optical axis.

ターンが得られる。In the projector type headlamp of this embodiment, the reflection plate 11 is moved in the direction of the optical axis by the position changing mechanism in response to the operation of the beam changeover switch to switch between the traveling beam and the passing beam. That is, when the beam changeover switch is operated to the traveling beam position, the reflection plate is moved to the position shown in FIG.
11 so that the optical axis of the reflecting surface 11a of the reflecting plate 11 and the optical axis of the light projecting lens 13 coincide with each other, and the second focal point F2 is
Above and outside the light beam. Therefore, all the light beams emitted from the light source 12 are reflected by the reflecting surface 11a, enter the light projecting lens 13, and are radiated through the light projecting lens 13 in a light distribution pattern of a traveling beam. When the beam changeover switch is operated to the passing beam position, the reflecting plate 11 is moved from the above-mentioned position (FIG. 1A) by the position changing mechanism to the light projecting lens 13, that is, the light shielding plate 14 side as shown in FIG. ),
The second focal point F2 is located between the light blocking plate 14 and the light projecting lens 13. That is, the light shielding plate 14 is located between the focal points F1 and F2, and a part of the light flux reflected by the reflection surface 11a is blocked by the light shielding plate 14 so that the light flux incident on the upper half of the light projecting lens 13 is reduced. Therefore, the luminous flux irradiated through the light projecting lens 13 is reduced, and the light is radiated downward, so that a light distribution pattern of a passing beam is obtained.

The front side is illuminated in the vehicle speed range to obtain a light distribution pattern that is sensitive to the vehicle speed. Further, even when the vehicle height or the vehicle body posture in the front-rear direction changes due to a change in the load or the like, the position of the reflector 11 is changed to maintain the irradiation position at a fixed position.

To change the light distribution pattern. In this second embodiment as well, a traveling beam is obtained at the position of the reflector 11 shown in FIG. 2A, but the reflector 11 is moved to the position shown in FIG. Then, a passing beam is obtained, and the amount of movement of the reflector 11 is controlled in accordance with the vehicle speed or light shielding, and a light distribution pattern corresponding to the vehicle speed and a light distribution pattern corresponding to the vehicle height are obtained.
この第２実施例にあっても、反射板11を平行移動させ
るため、配光パターンの調節範囲が大きく、また、反射
板11に複雑な反射面を形成する必要が無い。Even in the second embodiment, since the reflecting plate 11 is moved in parallel, the adjustment range of the light distribution pattern is large, and it is not necessary to form a complicated reflecting surface on the reflecting plate 11.
