Abstract
The lens contains a cup-shaped body with a lens bottom and a lens member extended upward from the lens bottom and forming a 49-degree included angle with the lens bottom. The lens member contains, from bottom to top, a number of layers, each having a number of refraction portions. Each refraction portion contains a number of refraction elements arranged in a concentric manner. According to the inclination angle of the lens member, dimensions of the refraction portions, and the distribution of refraction elements, the lens could be applied to various applications with enhanced coverage range and sensory effect.
