LED light source projector market trends

The last one or two years, in the field of liquid crystal display, television frequency of high LED light source in CES 2009 in a new image. CES 2009 International Consumer Electronics Show, LED light source is widely used in many domestic and foreign brands of the projector, LED light source is also considered a new alternative to traditional metal halogen lamp projector and the popular ultra high pressure mercury lamp.

Because the LED light source belongs to the cold light source, compared with the traditional projection bulb, the utility model has the advantages of low calorific value, long service life of 20 thousand hours and the like. Therefore, the application of the LED light source can be the size of the projector phone size, and do not have to use the same as the ordinary projector to replace the light bulb for about two years. From the industrial point of view, LED light source used in projectors as much as a technical upgrade.

When the projector's core components - the light source into the LED era, which will be the projector market in 2009 to bring what kind of impact? Below we will work together with readers to analyze.

LED light source to break the bottleneck of brightness

The application of LED light source to the projector as early as three or four years ago, but because the brightness is only several lumens to 10 lumens, unable to meet the daily needs of thousands of lumens projector, so LED light projector suitable always stay in the laboratory stage, and no mass production.

However, LED light source brightness bottlenecks finally achieved in 2008 breakthrough. Projector bulb manufacturer OSRAM announced in late 2008, has developed a new LED light source system, using the brightness of the light source to enhance the LED bulb to more than 500 lumens. The display at the CES2009 consumer electronics show several LED1080p projector also claimed that luminance reached more than 700 lumens, which comes from the area of our country Taiwan Qiling science and technology is the brightness announced that its LED has more than 1000 lumens projector. Some of these products are not explained, LED light source brightness has been very close to the brightness of the ordinary projector.

Many of these messages are passed on to us the fact that: in 2009, LED light source used in the projector is ripe. To solve the problem of low brightness, LED light source low calorific value advantages can make the projector volume be more compact, which means that the future of the business projector will realize the PSP size. In addition, the LED light source 20 thousand hours of life basically put an end to the use of the projector after a period of time the need to replace the phenomenon of light bulbs, the user's use cost will be greatly reduced. However, we can not ignore the early application of LED light source, the popularity of the high cost of production is not high possibility. But in the long run, LED light source will replace the existing metal halogen bulbs and the popular ultra high pressure mercury lamp, a new light source projector.
