Abstract
An optical element has at least one strip-shaped optical lens, the optical lens has a light source setting portion, a light incident surface, two first total reflection surface, two first light emitting surface and two second total reflection surface; the two second total reflection surfaces are set to tilt outwards so that the large-angle light are reflected to the direction of the small-angle light; and two second light emitting surface, respectively disposed on the two sides of the central axis and located between the second total reflection surface and the first light emitting surface on the same side; the second light emitting surfaces are used to emit the reflected light of the second total reflection surface from the same side.
