11384917 · 2022-07-12 · ·

A headlight for vehicles, including an image light source, a lens module, a lens cover, and a driving device, is provided. The lens module includes a lens assembly and an aperture. The lens assembly is disposed at downstream of an optical path of the image light source. The aperture includes a base and a movable mechanical member. The aperture is disposed at the downstream of the optical path of the image light source. The lens cover is disposed at downstream of an optical path of the aperture. The driving device is connected to the aperture. The driving device includes a power source and a linkage member connected to the movable mechanical member. The lens module includes at least two aperture values, and the aperture values are both not greater than 2.0.

REFLECTION-TYPE HEADLAMP MODULE, HEADLAMP MODULE, HEADLAMP AND VEHICLE
20220107070 · 2022-04-07 · ·

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.
