The Projector Light Source: Ultra-High Performance (UHP) Lamps

In the meeting or education, the computer projectors are increasingly popular. Developing a low cost, high efficient and high luminance lamp is the key to improve its pressure and increase its market share and penetration. The Ultra-High Performance lamps (UHP) are developed from High-Intensity Discharge (HID) technologies. The luminance of Ultra-High performance lamps can exceed 9,000 only with 150W power consumption. It has great potential to replace other technologies and become the main stream of the future computer projector industry. This paper discusses the market requires of Ultra-High Performance lamps, the environmental ideas, and their key issues, which include processes, structure, cap, and performance.
