Abstract

An optical projecting apparatus is used for providing a projecting light to a screen via a projecting lens, the optical projecting apparatus and the projecting lens collectively form an optical projecting system. The optical projecting apparatus includes a first solid state light generator generating a first light beam, a second solid state light generator generating a second light beam, a first wavelength-converting module, and a spatial light modulating module. The first wavelength-converting module converts the first light beam into a wavelength-converted light. The spatial light modulating module splits the wavelength-converted light into a third light beam and a fourth light beam, and transmits the second light beam, the third light beam, and the fourth light beam to the screen via the projecting lens.
