An LED headlight (100) includes a lens (130), a heat sink (120), at least one LED module (110) and a shelter (140). The lens includes a focal length (FL) and a focal plane (FP), wherein the focal plane (FP) extends from a focal point (f) of the lens and is perpendicular to an optical axis (OA) of the lens. The heat sink (120) is arranged along the optical axis of the lens, and a distance (D HL ) between the heat sink (120) and the lens (130) is greater than a distance (d') between the focal point and the lens. The at least one LED module (110) is arranged along the optical axis of the lens and in contact with the heat sink, a distance (D LL ) between the LED module and the lens is greater than the distance (d') between the focal point and the lens. The shelter (140) is arranged along the focal plane (FP) and configured to block light emitted from the LED module. |
