ABSTRACT:
A novel projection apparatus comprised of a projector mountable on a frame for projection of a video image onto any appropriate screen, a high intensity projection light source remote from said projector such that heat from said light source is not transferred appreciably to the projector, and optical light transmission means connecting the high intensity light source with the projector. The projector may be movable, e.g., pivotable and/or translatable, in which case appropriate structure may be included to enable such movement of the projector while still providing ample light to the projector.
