The rear also use LED light source "Seiko EPSON waiting

New product launches rear projector opened in November 30, 2005, Seiko EPSON announced that for the next generation of products are stepping up to explore the light emitting diode (LED) and semiconductor laser source. The current rear projection instrument adopts high pressure mercury (FHP) lamp. But because of the high pressure mercury lamp "reached the brightest state needs a period of time, not instantly lit" (Seiko Epson Corp imaging equipment business minister Hata Tadaaki) problems, so it needs to be improved. As one of the solutions is the use of LED light source can be easily achieved instant light.

The benefits of replacing the existing high-pressure mercury lamp with a LED light source are not only instantaneous. "You can expand the scope of color reproduction, to achieve a small and thin, extended life," (Yu Zhong Ming). The reason why we can expand the scope of color reproduction, because the use of light source with R (red), G (green), B (blue) 3 different wavelength peaks. Miniaturization and thinness are due to smaller light sources and smaller optical systems. High pressure mercury lamp needs to be replaced after a certain period of time, life becomes a subject, and the LED estimate does not need to be replaced.

However, the most difficult problem of using LED light source in the rear projection instrument is "insufficient light". In this regard, the need to pay close attention to the progress of LED manufacturers in the field of performance improvement, if you can get enough light LED hand, will soon be used (Hata Tadaaki).

Front projection type projector so high on light requirements unlike there have been a number of rear projector using LED light source products. Seiko EPSON is also stepping up the development of the use of LED light source projection projector. Different from the fixed type rear projection instrument, it is more beneficial to use the LED light source to realize the miniaturization. Estimated in 2006, the first will be in front projection projector field to accelerate the popularization and application of LED light source.
