摘要: Developed the science and technology, the projector price is suitable price for many people. They enjoy the oversize image easily. Nevertheless, the image unable comes out when light source is burned, unless replace its light source. The trend of projector is to improve illumination and quality. Under such a requirement, a small size, high illumination, and high efficiency lamp was developed, which is the Ultra-High Performance (U-HP) lamp. Currently, the Ultra-High Performance lamp plays an important role, and almost replaces the Metal Halide lamp. One important thing is that without suitable power, the Ultra-High Performance lamp can not start, and can not work for long time. In Ultra-High Performance lamp, it consumes the electrodes fast, enlarges the gap, extends the are length, and whites or blacks the inner shell. As well, more invalid lights are due to the arc deviates the focus of reflector. In addition, the applied power strongly affects the tungsten-halide recycle, and affects the lifetime. It is very important, but very few papers report the compatibility between applied power and lamps. Therefore, this paper will discuss the driving requirements of Ultra-High Performance lamp. It is very wonderful for many drivers and lamps designers. Likewise, the related acknowledge such as structures, processes, methodologies, and others are mentioned in this paper.
