The listing of LED companies is also emerging. At present, Shenzhen enterprises account for half of the listed LED enterprises. among them are maoshuo electronics, Lehman Optoelectronics, zhouming technology, Alto electronics, Ruifeng Optoelectronics, Lianjian Optoelectronics, jufei Optoelectronics, Wanrun technology and other representative enterprises. As of September 30, LED enterprises that are still trying to prepare for listing mainly include Ocean King, Yuanhui Optoelectronics, Op lighting and Regent Optoelectronics. Why are LED companies keen on listing? Relevant experts in the industry said that the industry is capital-intensive, and successful IPO companies have greater competitive advantages, thus accelerating industry integration. Listed companies have reached a higher level in the future. LED has many ways to develop industries. One is to increase orders and open up new factories. the other is that through listing and mergers and acquisitions, with a capital platform, enterprises can choose related enterprises in many small and medium-sized enterprises for mergers and acquisitions, bringing more possibilities for their own development. In the eyes of experts, some of the companies that are currently waiting for listing have high income and high gross profit margin, which will have a certain impact on the LED market after listing in the future. Taking Ocean King as an example, its prospectus shows that ocean King's main business income has remained above 1 billion yuan in the past three years, and the gross profit margin of its main business has reached above 70 for three consecutive years. Wu Jiao said. In the future, listed companies may pay more attention to a certain market segment and occupy a leading position in it. For companies that want to go public, they may also be singles with very good conditions and capabilities. Yan Shirong said. Focus on new areas, new markets, optical communications and plant factories are currently two key words worthy of attention in the field of LED applications. Among the 22 LED listed enterprises, many LED listed enterprises expressed their special concern about the application of LED in optical communication, which means that while more and more enterprises are optimistic about the application of LED in visible light communication, the willingness of enterprises to seize the market is getting stronger and stronger, and the competition is more intense. It is reported that Guangdong province has put forward three innovative directions for the future development of LED. One is visible light communication. Today, China has established a strategic alliance for technological innovation in the visible light communication industry in August. The second is ultraviolet LED, which has sterilization and disinfection functions and can be widely used in printing related industries, medical treatment and other fields. It is understood that the LED plant lighting factory has only developed in recent years. Because LED is a cold light source, and because its red light, blue light and other spectral light are very suitable for photosynthesis required for plant growth, LED optical distribution and intelligent lighting control, if combined with biotechnology, it will create unlimited development prospects. At present, the United States, the Netherlands, Denmark, Germany, Japan, South Korea, Taiwan, China, and the mainland are doing research and experiments. Among them, Japan has developed rapidly and has formed a market-oriented operation. Sony, Panasonic, Fujitsu, Mitsubishi, Rosen and other large companies have entered the LED Plant Factory.
