LED light source projection will usher in the spring of its development

LED projectors have been recognized by a wide range of projector manufacturers since their inception. People have high expectations for the long life and rich color of LED light sources. Many people think that he will be the best solution to solve the problems of high cost, short life and inconvenient maintenance of traditional projectors. However, the extremely low luminous efficiency of the LED light source has become the biggest constraint to his popularity.

Two or three years ago, the brightness of the newly launched LED projector was only a few lumens to tens of lumens, and the frame size was greatly limited. However, LED technology has developed rapidly in the past two years, and the brightness has been continuously improved. Now one or two hundred lumens can be easily realized, and a larger picture can be obtained. It seems that the LED projection is practically not far away. In 2009, Samsung introduced the SP-410M projector with a brightness of 170 lumens, which can easily project a large 60-inch screen. In the same year, Lixun launched a home projector H9080FD with up to 800 lumens and capable of playing 1920*1080 resolution, which caused quite a stir in the market. But what makes people even more sensation is the price of up to 150,000. Originally hoped for LED to reduce maintenance costs, I did not expect LED to bring a higher price. The high price has also become a new factor restricting the development of LED projectors.

However, as the country supports the development of the LED industry, the promotion of energy-saving lamps and the development of LED industry standards will greatly stimulate the development of the entire LED industry, making LED applications more extensive, thus laying down LED industrialization and marketization. A solid foundation, which will also increase the cost of LEDs, the popularity of LED light sources is just around the corner. Of course, LED projector manufacturers are also constantly striving to reduce the cost of the product. Not long ago, according to ACTO, the company will launch a variety of home LED projectors in 2010, and there is a 1080P projector with 800 lumens, but the price is not more than 20,000 yuan. Compared with the products that are as high as 100,000, it has already had a very large price advantage, making LED projectors more popular. The launch of this projector will lead a new wave of LED popularization. Yatu’s technical director Liang Xiangdong even predicted that LED light source will usher in a development blowout period in the second half of 2010 or the first half of 2011.

I believe that in the next two years, LED light source projectors will usher in the spring of development.
