Abstract
An LED vehicle headlight includes a lens, a reflector, a first light source, and a second light source. The lens has a focal plane. The reflector is located at a side of the lens, and the reflector is equipped with a first focal point and a second focal point, wherein the second focal point is located on the focal plane. The first light source has a first light-emitting surface confronting the lens. The second light source has a second light-emitting surface confronting the reflector. The first focal point is located on the second light-emitting surface, and the reflector is configured to reflect and focus light beams emitted from the second light-emitting surface onto the second focal point.
