Recently, the reporter learned that with the widespread application of green energy such as light-emitting diodes (LEDs) in the world, the export of LED lighting products in China is in a period of rapid growth. According to industry insiders, the LED industry is currently exporting strongly and the domestic market potential is huge. The LED industry is expected to usher in explosive growth in the next few years. In the 116th Canton Fair Electronic Lighting Exhibition District, the reporter saw that various domestic companies have exhibited a variety of LED lighting fixtures. Some companies have developed new products that can be controlled by Bluetooth. Some new products have also won the Canton Fair export products because of their novel design. The design award has attracted many overseas businessmen to come to consult. The LED export situation is very good this year. The export market in developed countries is stable, and the emerging countries are growing rapidly. The domestic and international markets are expected to show explosive growth in the next few years. Dai Yuanqing, general manager of LED Lighting Division of Shenzhen Maoxin Electronics Co., Ltd. predicted. According to industry insiders, before the invention of LED blue chip, white light could not be applied to the field of lighting. The emergence of blue light has enabled LEDs to truly enter the large-scale application stage of home, road outdoor and landscape, and to subvert the era of incandescent lamps and energy-saving lamps, which is conducive to reducing carbon emissions and environmental protection. Li Wenyu, assistant director of the Guangdong Semiconductor Lighting Industry Joint Innovation Center, told reporters that the LED industry is developing rapidly and the market prospects are promising. Guangdong's LED product exports reached 60 billion yuan last year, of which the Russian market grew very fast, with a growth rate of 100%. According to the calculations of relevant authorities, in the next three to five years, China's LED lighting products exports will maintain an average annual growth rate of 40%, of which the growth rate of the European and American markets is slowing down, and the growth rate of emerging markets is strong. According to the China Chamber of Commerce for Import and Export of Mechanical and Electrical Products, Russia, Southeast Asia and the Middle East are currently the fastest growing overseas markets for LED lighting products. At present, the domestic LED consumer market is still immature. The advantages and energy-saving concepts of LED products need further publicity and guidance. As the relevant product standards are gradually improved, the domestic LED market will also usher in rapid growth. Dai Yuanqing said. The changes in the LED industry's cold and warm, from the performance of listed companies can also be seen. According to the data of the mid-year report, the total operating income of the 22 LED listed companies in the first half of 2014 was 11.62 billion yuan, a year-on-year increase of 32%; the total profit was 1.79 billion yuan, a year-on-year increase of 31%. However, the Chamber of Commerce for Electrical and Mechanical Industry also said that although the market prospects are promising, China's LED lighting industry still has a series of problems such as overcapacity, fierce price wars and rising costs. The relevant market risks are gradually accumulating and must be paid attention to by relevant enterprises and departments. From the technical level, although domestic LED companies continue to increase R & D and innovation in recent years, there is still a big gap compared with international counterparts. Domestic LED enterprise technology still needs to be upgraded. 80% to 90% of enterprises are packaged and produced. The key chip technology is still in the hands of American, Japanese and Korean companies. Dai Yuanqing said.
3D Printing
3D printing (3DP) is a kind of Rapid Prototyping technology, which is a kind of technology to construct objects by layer-by-layer printing based on digital model files by using powdery metal or plastic and other adhesive materials.
3D printing is usually realized by digital technology material printer.It is often used in mold manufacturing, industrial design and other fields to make models, and then gradually used in the direct manufacturing of some products. There are already parts printed by this technology.The technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.
