Abstract

A headlight for use in a vehicle and comprising a lamp body a reflective mirror mounted in the lamp body and having a front opening, a bulb mounted in the reflective mirror and acting as the light source of the headlight, a douser plate mounted on the lamp body at the location between the front opening of the mirror and the bulb and intercepting a part of the light emitted from the bulb. The douser plate is supported on the lamp body such that the douser plate can incline transversely with respect to the lamp body, and driving device is provided on the lamp body for transversely inclining the douser plate.

Claims

1. A headlight for use in a vehicle and comprising a lamp body, a reflective mirror mounted in the lamp body and having a front opening, a bulb mounted in the reflective mirror and acting as the light source of the headlight, a douser plate mounted on the lamp body at the location between the front opening of the mirror and the bulb and intercepting a part of the light emitted from the bulb, means for supporting the douser plate on the lamp body such that the douser plate can incline transversely with respect to the lamp body, and driving means provided on the lamp body for transversely inclining the douser plate.

2. A headlight according to claim 1, further comprising means for detecting the inclination of the body of the vehicle, and means for actuating the driving means for transversely inclining the douser plate in response to the inclination of the vehicle.

3. A headlight according to claim 1, further comprising means for supporting the douser plate on the lamp body such that the douser plate can displace in the vertical directions with respect to the lamp body, and second driving means provided on the lamp body for displacing the douser plate in vertical directions.

4. A headlight according to claim 2, further comprising means for detecting the inclination of the body of the vehicle in longitudinal directions, and means for actuating the second driving means for displacing the douser plate in the vertical directions in response to the inclination of the vehicle in the longitudinal directions.

5. A headlight according to claim 2 wherein said means for detecting the inclination of the vehicle includes a rotor mounted on a gimbal device and driven by a motor, and means for detecting the inclination of the rotor with respect to the body of the vehicle.

6. A headlight according to claim 1, wherein the reflective mirror has the configuration generally of a paraboloid, the bulb is located generally on one of the focii of the paraboloid, and the douser plate is located near to the other focus of the paraboloid.

7. The headlight according to claim 3, further comprising means for detecting the inclination of the body of the vehicle in the longitudinal directions, and means for actuating the second driving means for displacing the douser plate in the vertical directions in response to the inclination of the vehicle in the longitudinal direction.

8. The headlight according to claim 4, wherein said means for detecting the inclination of the vehicle includes a rotor mounted on a gimbal device and driven by a motor, and means for detecting the inclination of the rotor with respect to the body of the vehicle.
