Elimination of heat barriers LED will usher in explosive growth

China Economic Herald News of LED semiconductor lighting, heating problem has been a failure to overcome obstacles, as heat sink technology innovation achievements with independent intellectual property rights -- a LED series of products and projects, identify the key nodes of lighting products of the current problems, successfully removing obstacles by wire and fan the way of heat dissipation, achieves the better heat dissipation effect.

According to the results of the inventor, senior engineer Zhang Yixing said, we can not only solve the problem of heat dissipation, and also make a fully comply with the "high efficiency, high reliability and low cost requirements of the LED driving power supply, a fundamental solution to the two problems restricting the development of LED, the last obstacle finally eliminated, we can imagine, hope LED years of explosive growth, will soon become a reality!

Old expert Zhang Yixing detailed technical achievements of the advanced performance and advantages

Since 12th Five-Year, with the state's support for LED lighting technology, technological innovation has gone up. In early 2013, the national development and Reform Commission and other ministries jointly issued the "semiconductor lighting energy saving industry planning", in the country to promote the healthy development of LED industry in the country, ". Accelerate the explosive pace of growth, the LED energy-saving lamps shine into more areas. In August this year, a LED heat sink and a series of products in Beijing through expert identification, showing an unlimited broad market prospects.

With the strength of technological innovation, a LED heat dissipation device and a series of products for the green energy-saving light source family added upstart, for the development of the LED industry plug wings.

Obvious effect agglomeration

For technology research and development, China's LED technology innovation level in the international arena is still in the development stage. Most of the lighting equipment is mainly used in landscape lighting, road lighting, and in the application of high-end products such as automotive lighting is relatively small. It is understood that even if the application in landscape, roads and other general lighting of the more prominent aspects of LED products, but, according to Zhang as saying on the market are mostly the mood for leisure, only 3 watts, 5 watts, 7 watts range, almost no production, life need more than 10 watt LED. LED has a certain number of watts is to ensure the production, life, good products, and now many of the huge volume of LED, expensive price and lack of reliability and other factors, seriously restricting the development of. LED good, long life, non-toxic, low heat, high brightness, energy saving and environmental protection, has a lot of advantages, called "LED lighting in twenty-first Century," the reputation, but many people are on the existing LED products prohibitive.

There are many reasons for this negative factor, the key reason, it is reported that also lies in technological innovation. Semiconductor lighting and display technology has been included in the national medium and long term scientific and technological development plan (2006-2020), the national and local governments at all levels to support. At the same time, based on the LED backlight flat panel display technology in recent years, the rapid development of LED TV, laptop computers, mobile phones, Pad and other display products have been widely used, has become a new economic growth point. High color rendering index, high efficiency, wide color gamut and high color stability of the next generation of LED light source technology, is a common key technology facing the semiconductor lighting and display field, but also the promotion of LED lighting products, and promote the next generation of high color saturation showed a key problem in /TV industry development urgent. In general lighting, the industrial structure has a prototype, the formation of Shenzhen, Xiamen and other seven national semiconductor lighting engineering industrialization base. With energy saving and emission reduction, green lighting, networking, smart city, ten cities, such as the development of the focus, will be the realization of LED intelligent lighting, laying a strong foundation for development.

Great efforts to build the country, is an important driving force for the rapid development of LED technology innovation and industrial development". But for now, whether ordinary or high-end lighting, lighting, said old expert Zhang Yixing, its development is limited, mainly by two technical problems tightly stuck, this is the LED heat dissipation problem and the high performance, low cost, stable and reliable power supply problems. In other words, it is the lack of technological innovation ability, not a breakthrough in the existing technical bottlenecks, resulting in a lot of LED products, and in particular, short-lived, some large volume and high price of LED products, so many people love to "use", from these too awkward, in essence, is mainly weak technological innovation performance.

It can be predicted that the key to the rapid development of China's LED industry is undoubtedly an effective solution and innovative technology products. In August 7th the national authority "of a LED heat radiating device and a series of product project appraisal meeting, expert opinion is that a LED heat radiating device to identify the key nodes of LED lighting products of the current problems, the wire form and fan for heat dissipation, small volume and light weight, and achieve a better radiation effect the. Driving power for the use of technology, can effectively eliminate harmonic current and improve the power factor, has certain innovation, and power factor correction circuit, which belongs to the passive power factor correction circuit, the low power consumption, good performance, low cost, has certain advanced level in similar technology. Experts suggest that the strengthening of industry university research cooperation, as soon as possible to form a complete LED lighting products, data support, in order to better industrialization.
