The great efforts of the country are an important “pushing hand†for LED technology innovation and “explosive†growth of the industry. But for now, whether it is general lighting or high-end lighting, with the words of senior engineer Zhang Yixing, its development is limited, mainly because it is stuck by two technical problems, one is the heat dissipation problem of LED, and the other is LED Drive power.
LED is hailed as the "green light source" for illuminating humans in the 21st century. People can't live without it because of eating, wearing, living and doing. It is widely used in production and life, with the level of national economy, social and cultural life. Further improvement, LED technology, especially high-end LED technology and products will have more in-depth applications. In many parts of the world, many countries have intensively invested in technology research and development and capital to develop. Infinitely broad market prospects, how to ride the trend and take advantage of the trend?
An LED heat sink and a series of product projects have made LED drive power that fully meets the requirements of “high efficiency, high reliability, low costâ€, which makes the drive power efficiency reach 94%, which fundamentally eliminates the serious impact on the stable operation of the LED drive power supply. The "difficult problem"; the heat dissipation problem has also been better solved. Through repeated investigations and experiments, it has achieved a good heat dissipation effect without the electrolytic capacitor overheating, the inrush current damage switch and the power frequency flashing. Disadvantages.
"Mastering the technology of LED lighting key nodes can maximize the benefits." Zhang Yixing said. The "Passive Power Factor Correction Circuit" turns "impossible" into "possible" and solves two key nodes that currently exist. Therefore, experts believe that this technology improves the power factor, eliminates harmonic currents, makes power loss small, good performance, low cost, and uses wire form and fan forced way to dissipate heat, small size, light weight, and good heat dissipation. effect.
Since the "Twelfth Five-Year Plan", the state has increased its support for LED lighting technology and industry. At present, the "13th Five-Year Plan" will start to increase support with the country's high attention to energy conservation, emission reduction and environmental protection. According to relevant statistics, once the LED lighting products form an “explosive†growth, popularize and promote to the middle, high and low-end markets, the annual total power generated by the Three Gorges Power Station can be saved for the country.
The technology has been demonstrated by experts such as Chang Yi, secretary general of the Beijing Institute of Lighting and Electric Appliances, and has identified the key nodes of the current problems of LED lighting products, which are innovative and advanced. An LED heat sink and series of product projects consist of four patented technical achievements such as heat dissipation and passive power factor correction. Zhang Yixing mainly aims to open up the “last mile†of industrial agglomeration and rapid development, and realize the “explosive†of China's LED industry. Growth and R&D design, experts suggest that it is necessary to form a complete LED lighting product as soon as possible, and seek a cooperation team to better industrialize and promote to the market.
In November last year, at the 2016 China Macroeconomic High-Level Reporting Conference and the 2015 China Industry New Benchmark Awards Ceremony hosted by the China Development and Reform Commission, China Development and Development Association, China Development Network, after the appraisal and evaluation of expert judges and WeChat, the Internet public Voted, Zhang Yixing high ticket won the 2015 China LED technology industry new benchmark character award.
