摘要：
An optical lens refracts and reflects a light to increase a luminance in a top direction of the optical lens and to decrease a luminance in a horizontal direction of the optical lens. The optical lens includes a central portion and a peripheral portion. The central portion has a convex shape. The peripheral portion has a concave shape. The peripheral portion surrounds the central portion. Therefore, a power consumption and a manufacturing cost are decreased.
