Abstract:
1. An optical projection apparatus, comprising: an optical lighting system provided with a polarized beam splitter which polarizes a white light flux received from a white light source and combines the white light flux with other light flux, thereby to output a predetermined polarized wave; a multi-lens array having a plurality of lens elements to receive the polarized light from the polarized beam splitter; a light separator which separates the white light flux passed through the multi-lens array into three primary color light fluxes in the order of red, blue and green and irradiates the three color light fluxes on one display element; and a projection lens unit having a plurality of lens elements which project the three color light fluxes modulated by the display element to a screen; wherein the display element receives the irradiated three color light fluxes from the light separator in the order of red, blue and green; wherein the light separator separates the white light flux to red, blue and green in an order of weakness of a spectral energy distribution of the white light source.
