Abstract:
1. A time sequence energy saving color separation system, comprising: a guide module for guiding light sideways relative to the guide module to a direction inclined to an emerging surface of the guide module; at least one light source provided on a surface of the guide module and composed of multiple light illuminating elements capable of illuminating light beams with different wavelengths and arranged in array, the at least one light source being able to illuminate light beams with specific wavelengths in two time sequences and entering the guide module; and a color splitting module provided on the guide module, comprising a first surface and a second surface, wherein the first surface is a collar structure per unit cycle and the second surface is a non-spherical structure per unit cycle, the non-spherical structure per unit cycle corresponds to the collar structure every two unit cycles.
