1. a color light combining system, comprising:

  • First polarization beam apparatus, described first polarization beam apparatus comprises reflective polarizer films, comprise the first prism surface and the second prism surface that receive the first unpolarized color of light and the second unpolarized color of light respectively, comprise the prism surfaces providing the first combined light to export, and comprise the 4th prism surface with the reverberator providing light to circulate, described first combined light exports the first color of light along the first polarization direction polarization and the second color of light along second direction polarization that comprise combination;

    AndThe stacking delay polarizing filter of first color selecting, described first color selecting stacking delay polarizing filter towards described prism surfaces and provide second combined light export, described second combined light exports to comprise and is combined and has the first color of light and second color of light of identical polarization directionAt least one wherein in colorama is produced by the color light source comprising a LED and the 2nd LED, a described LED produces the light of first wave length, described 2nd LED produces the light of second wave length, described second wave length is different from described first wave length, and the light of the light of described first wave length and described second wave length is in a kind of visually-perceptible color gamut.
