Abstract
A light concentrating module includes an optical film having a light incident surface and a light outgoing surface facing the light incident surface, an optical wedge element having a first surface, a second surface facing the first surface and having an angle with respect to the first surface and a third surface adjacent to the first and second surfaces, and at least one photoelectric chip disposed near the third surface. Light from a light source penetrates the optical film, and the light enters the first surface of the optical wedge element by an appropriate incident angle and has total reflection between the first and second surfaces, whereby the light propagates in the optical wedge element, and the light leaves the optical wedge element from the third surface and is received by the photoelectric chip.
