Modern projection light sources must be capable ofhandling obstacles such as heat and light concentration. This paper shall review the patented Cheng Orthogonal Parabolic Reflector (OPR®) and how it resolves these problems. High intensity discharge (HID) lamps may be optimized using the new compound OPR® designed together all light from their most intensely radiating areas to a 3mm point. Performance ofthis system is up to 100% better than existing systems for projection. This technology may be applied to a diverse combination oflamps and projection applications for increased performance and reduced cost.
