The new light source technology will be the rules of insurgents projection industry – Projector – Education Industry
2009 was the world's great turning point in the projector industry sprouted a year of hope. With two solid-state LED and laser Light source Technology, practical, long-term application of cost constraints projector products and application methods of the traditional mercury lamp light source is facing the possibility of the stage of history. The projector light sources to change the final product, it will completely rewrite the projector industry, "industry rules."
Traditional mercury lamps "problem" seriously
Modern digital projector display products, is a typical passive light-emitting display device. Its working principle is the use of special optical valves, issued on the light source, through a special plane after the light source modulation for each primary color of the path down to the control, then the screen reflection or diffuse scattering through the formation of large screen projection display device. This displays the key technology is the development of optical and control valves, lighting products and light modulation are two aspects of core technology.
Long time, the projector products have been used mercury as the basic source products. Mercury Lighting Have developed simple, simple structure, control and simplicity. However, high performance, high-color, high brightness and long life, long working stability of the mercury has not been easy. Projector light source products company focused on enhancing the brightness, lifetime and color effect of the unflagging effort. But until today the whole mercury products is not a perfect projection light source Solutions .
Mercury products are difficult to meet the long-life first design. The brightness and lifetime of the light source products tend to show an inverse relationship. The higher brightness of the shorter life expectancy. Now common in the low-intensity mercury vapor lamp life of the product only 4000 hours, while the high-brightness life of the product is only 2000 hours.
Mercury products in the design of products, high-brightness light lifting force is also facing shortage of thermal design characteristics of extreme complexity. High brightness Projectors Often used light bulbs to solve the problem of insufficient brightness of a single lamp, but this would increase the mercury products, optical design complexity. Meanwhile, the more the heat lamp higher, is not efficient as a light source technology, highlighting the application of the heat dissipation directly to the product's life: the excessive accumulation of heat even melted light bulb itself, and will significantly shorten product design life. Too complex thermal design, and the characteristics of mercury makes its own products to meet the projected 24-hour application of the cost of continuing to work has increased significantly.
Same time, the mercury is not a Environmental protection Light. First, the characteristics of their short life contrary to nature and environment protection; Second, mercury is used over the internal metal materials, including easy-to-volatile and highly toxic mercury; addition mercury lamp luminous efficiency is low, heat has a very serious energy waste. In emerging solid-state light source
09 challenges traditional mercury lamps Semiconductor laser technology and LED-based light-emitting technologies has become a new solid-state light source projector 2009, the largest display industry Aspect of technological progress. New display lighting applications is expected to solve the long-troubled projector industry source bottlenecks.
09, LED semiconductor lighting products grand debut. In the micro-projection, the semiconductor light source technology to achieve a more compact design, its new products in 2009 than in 2008 with the brightness of more than 150% performance increase. In the ultra-portable projector, Samsung and other brands has launched a very mature product. These products fall in prices over the past more than 60% of chief technology officer, doubling to twice the brightness level. In the home projector market in 2009 has 800 lumens of practical product launch. Education And business projector market, has achieved a Brand Lab Products 2700 lumens high brightness projector products. In engineering applications, DLP rear projection mosaic wall almost all the vendors have been able to provide 600 to 1000 lumens of practical alternative Consumables Products.
09 years is a practical laser source technology market a year. In both subjects, as in the laser light source, represented by domestic manufacturers have started practical laser source products.
