    摘要： A lighting unit is provided. The lighting unit includes a light source and an optical element. The light source provides a major light beam and a minor light beam. The optical element includes a first light entering surface, a second light entering surface, a light distributing surface, a light emitting surface and a normal line, wherein the normal line is perpendicular to the light emitting surface, and the second light entering surface is a scattering surface, and the major light beam enters the optical element through the first light entering surface, and is emitted from the light emitting surface, and the minor light beam enters the optical element through the second light entering surface, is reflected by the light distributing surface, and is emitted from the light emitting surface.
