Abstract
A light concentration device includes a light concentration plate. The light concentration plate has a first surface and a second surface facing away from the first surface. The light concentration plate defines a number of through holes running through the first surface and the second surface. The light concentration plate has a number of inner surfaces in the respective through holes. Each of the through holes tapers from the second surface to the first surface. The inner surfaces and at least one of the first and second surfaces are reflective surfaces.
