Patent ID: 7954983

Claim:
An optical component having a light exit surface and a light entrance surface on which at least one light source emitting lights to generate at least one optical path in the optical component is disposed, the optical component comprising: a plurality of microstructures, extended along a first direction and arranged along a second direction on the light exit surface, each of the microstructures having a top, the tops disposed on the light exit surface to form a plurality of first curves and a plurality of second curves adjacent to each other, the first curves and the second curves being extended along the first direction, said first curves being not parallel with said second curves such that a distance between one of the first curves and one of the second curves in the second direction is not equal, and a distance between said one of the second curves and another of said first curves in the second direction is not equal; and a plurality of reflecting members, each of the reflecting members extended along the first direction and arranged along the second direction on the light entrance surface, and the position of each of the reflecting members being among two microstructures, each of the reflecting members to the light entrance surface having a thickness t, a length of the microstructure in the second direction being a width P, the optical component having a refractive index n, and t, P and n satisfy a formula of tan −1 (P/(10t))>sin −1 (1/n); wherein the optical path is incident from the light entrance surface, and the optical path is controlled by the thickness of the reflecting members and converged by the microstructures on the light exit surface.
