2010 is expected to become the "semiconductor lighting era"

When the incandescent lights into Paris, World Expo in 1878, the human entered the era of electric light. The day before the closing of the "2008 Shanghai international LED (semiconductor lighting) Industrial Technology Exhibition", the experts said, in 2010, LED is expected to enter the field from the landscape and public lighting home lighting, Shanghai and World Expo is likely to be "the best opportunity to open the semiconductor lighting era".

As a solid state light source of semiconductor chip, LED uses the electron to move to emit light, and the electric energy can be directly converted into light energy. The conversion efficiency is as high as 68%, which is more than 5 times of the incandescent lamp. Therefore, the power consumption of LED is only 100 of the traditional light bulb, the service life is its 1/10. In the field of industry, Japan, South Korea and Taiwan technology research and development, but on the application, China is undoubtedly in the forefront. Including Shanghai, China has set up 7 national semiconductor lighting industrial base in the country, forming a more complete LED industry chain.

The more the more beautiful night night in Shanghai and the LED can be described as "soul". According to the director of the Shanghai semiconductor lighting engineering research center Guo Yansheng said in World Expo on 2010 in Shanghai, LED will do its best to beautify the city best practice area, widely applied to indoor and outdoor lighting, landscape decoration, signage, information display, staging and other aspects. By then, the entire Expo Park is expected to become the world's largest LED demonstration area. Currently, the Municipal Science and Technology Commission and other departments jointly launched a number of demonstration projects for the city's Expo Park LED display before the war". Including the completion of the Chongming avant-garde village, North Road, north of the road landscape lighting demonstration and the ongoing Yu Garden area of more than 40 buildings of the ancient landscape of the re design works.

With the continuous decline in the cost of LED, for ordinary people, the use of LED lights will no longer be electricity saving does not save the public interest. It is understood that a few years ago, the market price of LED lamp is 10-20 times the traditional light bulb, the gap has narrowed to seven or eight times. Expected two or three years later, the price of LED lamps will be reduced to 3-4 times incandescent lamp, the comparative advantage is obvious, is expected to enter the homes of ordinary people.

Out of the ordinary lighting, LED lighting in the field of special lighting should not be overlooked. The exhibition site, a LED backlight LCD TV developed by our own country and currently on the market CCFL (CCFL) LCD TV comparison debut, differences in the effect of eye popping -- whether it is realistic effect of brightness, color, or picture clarity, LED high technology to raise.

Originally, the LCD screen must rely on passive light source, its backlight technology or CCFL, or LED. Compared with the former, the biggest advantage of LED backlight is strong color expression, in the display of flowers, landscapes and other static things, the color of the gorgeous, the level will be particularly prominent, eye-catching. At the same time, LED backlight LCD TV color gamut is also much wider than the CCFL, can display about ten million colors, so that the quality closer to the real world. In addition, the difference between the two power consumption is obvious, by field measurements, LED lighting TV consumption is only the traditional 40%-50%.
