ABSTRACT:
The present invention relates to an optically integrated device, and more particularly, to an optically integrated device with low light loss. The optically integrated device includes an optical condenser to condense the light before the light enters an optical integrator. A color filter is attached on the optical integrator to filter through a portion of the light, and reflect the other portion of the light into the optical integrator. The optically integrated device recycles the reflected light inside the optical integrator to prevent the light loss.
