  • Patent number: 11841121
    Abstract: A reflection-type headlamp module, comprising a light source, a light-converging element, a reflecting element and a lens, wherein the light-converging element is suitable for converging light rays emitted by the light source and projecting the light rays; and the reflecting element is arranged on a light-emergent light path of the light-converging element, and is suitable for reflecting, to the lens, the light rays emitted by the light source and projecting the light rays via the lens to form an illuminating light pattern. The reflecting element of the headlamp module changes the propagation direction of light rays, so that the front and rear diameter of the module is greatly reduced. In addition, high-beam light and low-beam light can be switched quickly and noiselessly, preventing the influence of a high-beam light path and a low-beam light path on each other. Further disclosed are a headlamp and a vehicle using the headlamp.

  • Patent number: 9316374
    Abstract: A vehicle headlight utilizes a rotationally asymmetric projection lens with its light emitting surface inclined with respect to the optical axis thereof, whereby the light emitted from the light source and projected forward through the light emitting surface of the projection lens is diffused substantially uniformly with respect to the optical axis of the projection lens, for example, uniform substantially in the right and left directions and/or the upper and lower directions. This can be achieved by designing the reflecting surface to have its optical axis inclined with respect to the optical axis of the projection lens by a predetermined angle so that light emitted from the light source and projected forward through the light emitting surface of the projection lens is made uniform with respect to the optical axis of the projection lens (for example, uniform substantially in the right and left directions and/or the upper and lower directions).
