Super light bulb will illuminate the Shanghai tunnel to break the current brightness limit

As bright as ordinary bulbs, but only 1/10 of its energy consumption. Such a super light bulb will be in the bridge and the tunnel flashing light, replacing the commonly used high-pressure mercury lamp, which is a reporter yesterday from the fourth China International Semiconductor Lighting Exhibition learned. Currently, Shanghai is focusing on scientific research, focusing on the development of such a group of high brightness LED products, for the pilot application in 2010.

Breaking through the brightness limit

The same lighting 10 square meters, the ordinary lamp needs a power of 60 watts, but as a semiconductor lighting LED lamp requires only 3.2 watts. Relevant data show that if the country's 50% lighting are used in the latter, which can save at least one of the Three Gorges dam.

How to make the LED lamp in the approved power shine brighter? This reporter has learned that Shanghai is currently tackling the problem of breaking the current limit of 60 lumens per watt". To undertake the 863 issue of Shanghai Blaupunkt photoelectric materials Co., Ltd. Chen Mingfa said, to 2010, the city should take the lead in the study of the product of 100 lumens per watt, and put into industrialization. To 11th Five-Year, but also to make the research objectives to achieve 135 lumens per watt.

Three years after the tunnel light

Brightness up nearly 1 times, power consumption has not changed. "Chen Mingfa said, this new product will make the application scope of the LED lamp has been greatly expanded, one of the most important uses in highway, bridge, tunnel and square lighting using high pressure mercury lamp to replace the original high temperature and high power consumption.

Experts pointed out that although the high pressure mercury lamp is very bright, but the same amount of power consumption, as well as mercury pollution under high heat. With the convening of the World Expo, Shanghai new tunnel, road and other increasing, light sleepless night on the city electricity generated no small burden. Once the brightness has been greatly increased, the LED lamp will be gradually applied to the lighting projects before 2010.

Annual investment in science and technology over ten million

In fact, in recent years, Shanghai has been vigorously promote the use of LED lights demonstration. Wujiaochang "egg", the Oriental Pearl lighting, the East China Sea Bridge Landscape, Chongming avant garde village lighting...... These are many people familiar with the project.

Shanghai invested more than 10 million yuan in semiconductor lighting and key technology in science and technology every year. Municipal Science and Technology Commission official said that from 2000 onwards, Shanghai launched a special implementation plan, and the semiconductor lighting listed in the 11th Five-Year focus on the development of strategic products. Wait until World Expo, semiconductor lighting will shine. "
