UHP lamps-the heart of modern video projectors

摘要

While the technology behind the LCD,LCOS and DLP panels used in modern video projectors is impressive,all that would count for nothing without the UHP lamp which provides the very high light output to drive them.UHP stands for"ultra high performance"or"ultra high pressure",depending on which literature you are reading.UHP lamps are very expensive to replace,typically 500 to 700,and their life is typically around 3000 hours.That very high cost is much greater than the lamps used in 35mm slide projectors and the difference is due to the complex technology used in UHP lamps.
