1 thousand lumens LED projection listed on the end of the traditional light source

2009, LED light source is widely used in the projector market and from 1 kilograms of the ultra portable projector brightness only 15 lumens, micro projector weight only about 100 grams, and the brightness of 800 lumens, and using 1920 x 1080 resolution full HD projector, have a good product launch.

But the brightness of these products has always been difficult to meet the needs of users, only 150 lumens of ultra portable projector, can only be projected on the more dark environment the big picture, and the brightness of 800 lumens Luxeon H9080FD price up to 150 thousand yuan, for the majority of consumers, or difficult to bear. So, there is no use of LED light source projector, you can take into account the performance and cost, so that consumers can afford to buy the product?

In early 2010, the U.S. consumer electronics show, Samsung released the LED SP-F10M light projector brightness up to 1000 lumens, surpassing the Vivitek launched in the 09 years of H9080FD, has become the industry's highest brightness LED light projector. The day before, the Samsung projector has been released in the country, and will soon meet domestic consumers.

Samsung SP-F10M projector is as high as 115.6% NTSC color gamut, let us see the great advantages of LED light in color, with only 158 watts and 30000 hours in the life of the light source, make it far beyond the traditional projector light source.

By virtue of the inherent advantages of LED light source, this product can subvert the entire projector industry, so that the traditional light source projector no way to escape? And whether the listing of this product will allow LED light source projector become the mainstream of the market? Below, the author in many aspects for the following analysis, LED light source projector will become the mainstream of the future.

Technology: a number of leading edge of traditional light source

Many years ago, LED light source was high hopes, when a lot of people in the industry predicted that LED will replace the traditional light source in various fields. The LED light source is what?

LED is a light emitting diode, it is a solid state semiconductor devices, can directly convert electricity into light. The utility model has the advantages of small size, low power consumption, long service life, low heat dissipation, wide color gamut, etc., and the utility model is the best choice for the new light source of the projector.

LED light source used in the projector, with small volume, low heat quantity advantage, can make the projector structure is greatly simplified, the volume is greatly reduced. We launched two years from the projector can see, can be reduced to only 90 grams of using LED light source projector volume, micro projection module can also be embedded in the mobile phone, digital cameras and other handheld devices, and the weight of 1 kg in the ultra portable projector has become a good choice for personal entertainment.

LED light source in the projector applications, the biggest feature is the number of long life. As we all know, the traditional projector lamp life only 3000 hours, with a low brightness mode, the longest can only reach up to 6000 hours. At the same time the price of the bulb is also very expensive, generally around 1000-2000 yuan, it is no wonder that a lot of friends in considering the purchase of the projector, will ask the question, "is it expensive? "LED source of life is very long, the longest theory can be up to 100 thousand hours, and the latest Samsung F10M life up to 30000 hours, that is to say when you buy this projector, do not need to replace the bulb.

In addition, the projector, the color of the screen is also very important. The traditional color saturation of the projector is generally in the range of 80% NTSC color gamut, the color of the home machine will be slightly better, and the use of LED light source will greatly enhance the gamut range. In particular, the use of three primary colors of the LED light source, so that red, green, blue three colors with 256 levels of gray and arbitrary mixing, you can produce a 256 x 256 x = 16777216 color. We tested this Samsung F10M color saturation reached 115.6% of the NTSC color gamut, significantly beyond the traditional light source color gamut.

These are only the most important advantages of LED light source, in addition, including mercury free environmental characteristics, low power consumption and other characteristics, but also to become the mainstream of the future light source technology.

: manufacturers to reduce costs will subvert the market

From the vendor side, LED light source projector widely used, will bring the huge development of the projector market. We can see that the launch of the LED light source projector manufacturers, including Samsung, LG, BenQ, with Optoma and other manufacturers, especially Samsung and with two manufacturers, are entering the projector market just a few years, with the technological innovation, in a short period of time as the mainstream manufacturers in the projector industry.

And traditional mainstream projector brand for the application of a new light source is still very small, there is little use of LED light source products launched in the market, by virtue of the brand effect and market share in support the overall situation. Although, through energy saving technology, so that the traditional light source has a certain extension of life, but the use of low brightness mode of life is only 6000 hours long.

At the same time, the traditional light source in technology inherent disadvantage in color saturation is also difficult to have greatly improved the traditional projector, at present our evaluation of the color saturation test also can only reach about 80% of the NTSC color gamut, on the one hand to LED light resistance balance.

Of course, LED light source also has its own defects. First, the traditional projector
