Abstract
A headlamp optical element with a III-region light shape forming structure that comprises a light collecting portion, a first light emitting portion, a reflecting portion, and optionally a second light emitting portion. The light collecting portion converges incident light and emits light via the first light emitting portion. Some light may be directly emitted to the second light emitting portion. The rest of the light may be reflected by the reflecting portion and emitted to the second light emitting portion. The reflecting portion is connected to the lower portion of the first light emitting portion, with a lower beam cut-off line structure at the other end thereof. The light emitting surface of the first light emitting portion comprises multiple step surfaces with segment differences or is a single curved surface.
