Abstract: An LED headlight includes a lens, a heat sink, at least one LED module and a shelter. The lens includes a focal length and a focal plane, wherein the focal plane extends from a focal point of the lens and is perpendicular to an optical axis of the lens. The heat sink is arranged along the optical axis of the lens, and a distance between the heat sink and the lens is greater than a distance between the focal point and the lens. The at least one LED module is arranged along the optical axis of the lens and in contact with the heat sink, a distance between the LED module and the lens is greater than the distance between the focal point and the lens. The shelter is arranged along the focal plane and configured to block light emitted from the LED module.

Abstract: A vehicle lamp includes a condenser lens, a heat-dissipation base, a first light source, a second light source, and a reflector. The condenser lens has a focal plane and an optical axis. The heat-dissipation base is disposed at a side of the condenser lens, and the focal plane is disposed between the condenser lens and the heat-dissipation base. The first light source is disposed on the heat-dissipation base, and includes a first light-emitting surface facing toward the focal plane. The second light source is disposed on the heat-dissipation base, and includes a substrate and second light-emitting surfaces disposed on the substrate. A reflector is disposed on the heat-dissipation base and has reflective surfaces. Each of the reflective surfaces is a partial curved surface of an ellipsoid, and has a first focal point and a second focal point located on the focal plane.
