摘要： A light convergence structure includes light convergence portions. Each light convergence portion includes a frustum structure and a plano-convex structure. The frustum structure includes a first end surface and an opposite second end surface. An area of the first end surface is less than an area of the second end surface. The plano-convex structure is on the second end surface of the frustum structure. The plano-convex structure includes a flat surface and an opposite convex spherical surface. The flat surface is in contact with the second end surface. An area of the flat surface is equal to the area of the second end surface. The first end surfaces of the light convergence portions are coplanar and together define a light incident surface of the light convergence structure.
