Experts suggest that Nanjing should build energy-saving emission reduction LED bridgehead"

With the continuous growth of the global population and economic scale, low carbon economy has become a major progress in human society after the agricultural and industrial civilization. Nanjing science and technology conference held yesterday, the Southeast University, experts advice: Nanjing should focus on the layout of high-power photonic crystal LED industry chain, will be built into a model of energy-saving emission reduction in Nanjing.

Nanjing experts to overcome the bottleneck of LED Technology

Low carbon economy is the essence of energy efficient use, clean energy development, the pursuit of green GDP, the core is energy and energy saving technology innovation. The semiconductor LED light source is one of the core technologies of energy-saving emission reduction, if we can seize the commanding heights in the LED industry, no doubt will lay a good foundation for the transformation of Nanjing into a new city.

In yesterday's spring conference, Nanjing optical communication and Optoelectronics Association chairman, Southeast University professor Sun Xiaohan made "suggestions of experts in Nanjing have focused on planning and layout of major power industry chain" of the photonic crystal LED. She believes that the current energy consumption in the field of lighting, LCD panels, projection, stage lighting, etc., the need for high brightness high-power semiconductor light source. In recent years, the experts in Nanjing have made a breakthrough in the research of photonic crystal LED, and the semiconductor chip is used to control the temperature directly, which can reduce the heat source greatly. A series of technical bottlenecks, so that in the field of building LED chain in Nanjing to walk in the forefront of the country.

Therefore, Professor Sun Xiaohan suggested that Nanjing can have a plan and focus on the layout of high power photonic crystal LED industry chain, as soon as possible to construct a key base, rapid digestion and absorption and master all design and production technology, forming the core technology with independent intellectual property rights, to fill the gaps in national high power photonic crystal LED chip industry.

High prices, the promotion will take time

The application of LED technology in the light is not no tungsten lamp, light emitting device, as long as through a special chip can transform electricity into light - as a new lighting technology, LED because of its energy saving and environmental protection, long service life, quick start is generally optimistic. Currently in the city of Nanjing, the model has been the first to use the road tunnel on the LED lamp, the current use of more than 50% of the high-pressure sodium street lamps to save electricity. It was calculated, Nanjing existing more than 160 thousand high-pressure sodium lamp, if each street lamp hourly power consumption of 0.5 kwh, the city's street lighting power at about 320 million kwh. If all the LED street lights, at least 160 million kwh electricity saving, coal saving more than 50 million tons.

Although the LED lamp has such advantages, but the promotion is not satisfactory, only a few roads in the city of Nanjing with the new light source. The reason is the core technology in the hands of foreigners, resulting in high prices. However, from the point of view of experts yesterday, we Nanjing experts have overcome the relevant technology. We have completed the development of InP multi quantum well photonic chip, has carried out a number of photonic crystal LED, LED packaging research. "A professor Sun said," next, we hope to set up the Nanjing new high power LED research center jointly with relevant research and production enterprises, and lay the foundation for the formation of energy-saving light industrial chain in Nanjing. Experts confidently said that as long as we have mastered the core technology of LED, the price will certainly come down, then in the general public to promote the use of LED lights on the ripe.
