Do not change the light bulb LED rear projection

The release of pure high-definition digital TV standard 55 inch rear projection instrument. FHP light source.

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.

Will present a LED high pressure mercury lamp light source is not only the benefits of instant light. "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.

The biggest problem but the rear projector using LED light source is at present insufficient amount of light "(pinna Tadaaki). 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 requirement to light as the rear projector there have been a number of 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.
