ABSTRACT:
An optical lens includes a recessed part and a refracting part. The recessed part has a substantially circular plan view and a substantially V shaped cross-section. The recessed part forms an angle of no more than an angle of about 20° with respect to a vertical line. The recessed part has a plurality of curved surfaces including different radii so that a light incident into the recessed part is totally reflected from the curved surfaces. The refracting part has a substantially circular plan view extended from the recessed part. A light incident into the refracting part and the reflected light from the recessed part are refracted from the refracting part. Therefore, a luminance uniformity and a color uniformity are improved.
