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 150 W 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
