To some extent, LED is in its infancy, although LED has already passed the infancy in terms of time, but my feeling is that it will go a long way in the future. LED inventor Nick Helenak told the media in October this year. This year is the 50th anniversary of the birth of LED. It is not unreasonable for the originator of LED to be so sigh. The LED technology changes too fast, and the price drops quickly. It can be said that the price runs faster than the industry. The chip is in the upstream, the price of the chip changes, and the downstream will change. If the company does not innovate for 3 months, it will fall behind if it does not introduce new products. Technology is developing fast, and the industry is not mature, which is very painful. Dong Zhijiang, general manager of Wuhan Diyuan Optoelectronics Technology Co., Ltd. said in an interview.
Is the LED in its infancy?
American scientist Nick Helenak invented the first visible light-emitting diode (LED) in 1962. Today LEDs are everywhere, from traditional displays to automotive lights, flashlights, landscape lighting, general lighting, etc. LED has been expanding the application space.
Professor Jiang Fengyi, vice president of Nanchang University, said in an interview: From a technical point of view, I agree with the infancy. In terms of illumination, blue light-excited phosphors are currently commonly used. Because the development of LED technology is not perfect enough, the luminous efficiency of yellow light and green light is not high enough, and only the blue light can be used to illuminate the phosphor to achieve illumination. Strictly speaking, LED lighting is not really LED lighting, and LED fluorescent lamps are more scientific. LED technology development space is very large, efficiency and cost reduction, all need to be mature technology. I hope that the industry should have a rational mindset and not pursue rapid expansion. The expansion is too fast. When new technologies and new equipment appear, the previous production line may be like scrap iron, and the equipment may be useless. This is very cruel to the enterprise. Therefore, the concept of infancy is proposed, and it is hoped that the industry will pay more attention.
Yu Binhai, vice chairman of Foshan Guoxing Optoelectronics Co., Ltd., also agrees with the infancy. In fact, whether the baby is described in infancy, early childhood or adolescence, the LED industry is still not in maturity and stability. Therefore, in the process of rapid development of technology, how to develop the industry needs to think. Yu Binhai said.
The space for technological innovation is large. At present, the power efficiency of blue-light electro-optical conversion has reached 70, but the power efficiency of electro-optical conversion of green and yellow light is far lower than that of blue light. It is waiting for scientists to continuously carry out technological innovation and greatly enhance the illumination of yellow-green light. effectiveness. Jiang Fengyi said. This coincides with Helen Yak’s point of view. The LED you see today is at a low price, but that's just a form. He Lun Yake said.
LED technology is in rapid development, and the space for technological innovation is very large. Therefore, experts suggest that the state should continue to increase investment and lay out early research and development work for next-generation LED lighting technology, such as non-phosphorescent white LED lighting technology, ultra-high efficiency. The green LED technology and ultra-high efficiency yellow LED technology form the competitive advantage in the future market. The LED industry is one of the few industries in China with little difference from the international advanced level, especially the silicon substrate LED technology, which is generally optimistic internationally. In fact, the key technology of silicon substrate LED is the first breakthrough in China, and has many original invention patents. If the enterprise can become bigger and stronger, it will be an effective way for China's LED field to break through the patent blockade of international companies.
The LED industry is an important part of strategic emerging industries. Strategic emerging industries have three major characteristics: rapid product performance, rapid cost reduction, and a gradual increase in the application market. LED is a sunrise industry, currently in infancy, the technical route is full of uncertainty, product upgrading is fast, can not be developed as a mature industry, the current stage is the key cultivation stage.
At present, some local governments are eager to seek success and put forward unrealistic development goals. At this time, investors, scientists, entrepreneurs, and government officials need to be treated rationally, scientifically and orderly, and good things can be done well. It is expected to become the leading industry in China and everywhere.
Grasping the market stability and quickness There are many descriptions of the industry maturity, but technically speaking, the technological changes in mature industries will not be too great, and product performance will not be ups and downs. From this perspective, the LED industry is still in the changing age of children. However, due to the immature LED industry and technology, it is in a period of constant change. Therefore, its development space is also extremely large, and the LED industry is worth looking forward to.
Fan Yuxi, chairman of Xiamen Hualian, believes that from the long history, the development of LED technology has no end, great potential, not only in the field of lighting, LED technology is developing in other fields, such as medical, agricultural, data transmission. The current application does not represent the future. With the continuous breakthrough and development of technology, the future application field has huge imagination. At present, LED is technically, and its development potential and application space are huge. LED is still in its infancy. From an industrial point of view, this little baby needs to grow and rely on market support. The market application guarantees that LEDs will grow from infants to teenagers and youth. There are many problems to be solved at present, and it is necessary to treat the problems faced by the LED industry like a baby. Fan Yuxi said.
No entrepreneur does not pay attention to the market. In the current situation, what needs to be paid attention to is the LED market? Enterprises must have their own positioning, can not do what others do, do what they do, and what path do you take when others go, in the troubled times, enterprises must keep their minds clear, strive for stability, grasp the market, and practice internal strength. Fan Yuxi stressed. Yu Binhai also believes that the current LED industry chain from upstream materials, chips to downstream applications, the price is changing from month to month, there is no way for enterprises and channel providers, users do not dare to buy, inventory backlog, from the business model This is a fatal problem.
Due to the advancement of technology, the price changes frequently, and the damage to the industry cannot be avoided. However, in the period of rapid technological development, what kind of business model the enterprise chooses, how to position itself, requires a clear mind and correct judgment.
LED: Looking for a good start in the "infancy"
