Guangdong to promote the development of LED industry

December 04, 2019

At the end of May this year, the "Guangdong Province's Implementation Plan for Promoting the Use of LED Lighting Products" (hereinafter referred to as the "Program") was formally introduced to inject a shot in the core of LED industry development in cities across Guangdong. The program takes the contracted energy management (EMC) model as the carrier, uses the power grid as the management implementation subject, and takes public lighting as the breakthrough point to establish a government-led and market-operated LED lighting product promotion system. It is proposed that Guangdong should strive to popularize LED public lighting by the end of 2014, drive the whole society to popularize LED lighting, and pull the LED industry to achieve an annual output value of 500 billion yuan or more at the end of the “Twelfth Five-Year Plan” period.

The LED industry has also been highly valued by the Guangdong provincial government. In 2008, the Guangdong Provincial Government took the lead in the implementation of a large-scale replacement of LED street lamps and demonstration projects of major demonstration projects of LED street lamps; organized and implemented the “1,000 Miles” high-power LED street lamp industrialization demonstration project; in 2010, the Guangdong Provincial Government’s executive meeting will The LED lighting industry is listed as one of the three strategically emerging industries in Guangdong Province; in 2011, the “Twelfth Five-Year Plan for the Development of LED Industry in Guangdong Province” was formulated....

What is the basis and significance of Guangdong's efforts to develop the LED industry? In the process of comprehensive promotion of LED lighting products, what issues should be noted? To this end, this reporter interviewed authoritative experts in this area, Professor Hong Hong, director of the Optoelectronic Engineering Technology Research Center of South China University of Technology and a doctoral supervisor.

High degree of industrial linkage to drive efficiency Wang Hong pointed out that Guangdong has 60% of the lighting companies in the traditional lighting products, and accumulated experience and channel advantages in the traditional lighting industry. At present, the packaging and application fields in the middle and lower reaches of the LED industry in Guangdong Province are far ahead of the rest of the country, forming a number of leading enterprises.

Guangdong Province has fully promoted LED lighting. Wang Hong believes that this move will help improve and optimize the industrial structure of the lighting industry. The LED industry covers many fields such as energy conservation, environmental protection, high-tech, microelectronics, and major equipment manufacturing. The industry's horizontal correlation and vertical correlation are strong. In addition, it also plays an important role in the information industry, automotive electronics, raw materials and equipment manufacturing, consumer electronics, aerospace, solar photovoltaic, and the entire optoelectronics industry.

In addition, LED technology is regarded as a key breakthrough point in the development of semiconductor technology in the 21st century, and will drive the development of the third-generation wide-bandgap semiconductor technology. It is an important entry point for overcoming semiconductor optoelectronic technology, and it is extremely advanced for the development of a new generation of information technology. Important strategic significance.

LED as a green light source is an important way to promote energy saving and emission reduction in Guangdong Province. If calculated by 50% energy saving compared to conventional lamps, Guangdong LED industry can save 18 billion kwh per year, equivalent to saving 6.5 million tons of standard coal per year.

According to the research and forecast, the contribution of semiconductor lighting and LED display industry to Guangdong Province's GDP in 2015 will reach 230 billion yuan.

There is no need to cross the technical threshold. Wang Hong believes that after the "Eleventh Five-Year" period during the demonstration project's leading role in the field of public lighting, LED light source technology is more mature, higher product quality, basically has a large-scale promotion and application of the conditions.

In the process of promoting the LED, it is necessary to pay attention to some issues: First, many technical thresholds need to be crossed. In addition to packaging, LED companies in Guangdong are in a weak position in these key generic technologies and they still need further research. The second is that foreign patent barriers need to be broken. Although the development space for LED lighting technology is very large, the core patents are basically controlled by several foreign companies. Third, the competition in domestic and foreign markets has become increasingly fierce. At present, only a few enterprises in Guangdong can independently develop LED application products for the market, and they lack the key products with core technologies and market competitiveness. Fourth, the construction of a talent team needs improvement. At present, LED industry R&D talents, especially high-end leading talents, are lacking, which has become a shortcoming for Guangdong's LED industry to achieve high-end development.

Wang Hong suggested that the government can increase its efforts in talents and technologies from the aspect of capital, encourage technical innovation in the LED manufacturing industry chain, supporting raw material industrial chain and supporting equipment industry chain, and form a breakthrough in key technologies for its own intellectual property rights. It is guided by the R&D of competitive products in the market that has taken a leading role in the industry as a whole and applied to promote the rapid development of the overall industry.

In addition, LED products are further promoted to promote standardization and modularization of LED products in the country; to give full play to the enthusiasm of governments at both the provincial and municipal levels; to take leading enterprises as the foundation; to pay attention to market segmentation; to form regional characteristics and to bring points together to form a comprehensive industrial chain in the province. development of.
