Analysis on the innovation and industrialization of LED products in China

LED English word acronym, meaning: LED = Light Emitting main Diode, light emitting diode, is capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light; LED Large ELectronic = Display, LED = large electronic display; Lupus erythematosus disseminatus, systemic lupus erythematosus, a chronic idiopathic autoimmune disease; LED is the past tense and past participle of lead, meaning "leadership, led the Russian Pulkovo Airport IATA code. This article mainly introduces the light emitting diode.

LED has many uses, such as the relationship between visible light spectrum and LED white light. All the week, visible light spectrum of the wavelength range of 380nm ~ 760nm, the human eye can feel the seven color - red, orange, yellow, green, green, blue, purple, but the light of these seven colors are each a single light. For example, the red peak wavelength of LED is 565nm. In the visible light spectrum is not white light, because white is not monochromatic light, but light composite by a variety of monochromatic light synthesis, as the sun light is composed of seven kinds of monochromatic and white light, white light color TV is composed of three primary colors of red, green and blue synthesis. Thus, in order for LED to emit white light, its spectral properties should include the entire visible spectral range. However, it is not possible to manufacture this kind of LED under the current technological conditions. According to the research of visible light, the human eye can see white, mixed with at least two light, two light emitting wavelength (blue light and yellow light emitting wavelength) or three (blue light + + red light green light) model. The above two modes of white light, blue light, so the need to absorb the blue light has become a key technology for the manufacture of white light, that is, the current major LED manufacturing companies chase the Blu ray technology". At present, the international master Blu ray technology manufacturers only a few, so the promotion and application of white LED, especially the promotion of high brightness white LED in China there is a process. Therefore, LED enterprises should strengthen the training of professional and technical personnel, set up a high level, stable R & D team, and constantly improve China's scientific research and innovation ability.

Innovation difficulty and development bottleneck

China started late in the LED industry, engaged in the upstream LED epitaxy, chip manufacturers are numbered. According to statistics, at present, China's LED chip supply accounted for only 8% of global demand, in the mainland LED market, the domestic chip accounted for only about 52% of demand. Although in recent years, the rapid development of LED industry in mainland China, the outstanding performance of enterprise innovation, but the difficulty of innovation and development bottlenecks have gradually emerged.

LED enterprises in the process of product and technology innovation and industrialization of the bottlenecks and difficulties faced by patents, talent, Cheng Bensan big problem. Specific performance:

First, the mainland LED patent applications less, and started late. To obtain the core patent, still need long-term, high level of accumulation of research results. With the rapid development of domestic LED industry, occupy the international market ground become long-term goals. Thus, LED epitaxy, chip patent problem is particularly prominent, has become the first to solve the problems in the development process of LED company;

Two is the shortage of professional and technical personnel is still a common problem faced by LED companies. Three is the LED epitaxy and chip manufacturing equipment and the main raw material is difficult localization. At present, in the above demand is still dependent on imports, with the LED industry to the ultimate goal of the general level, to reduce costs has become a problem that must be faced in the production of enterprises.

Therefore, we should strengthen the training of professional and technical personnel, set up a high level and stable R & D team, and constantly improve our scientific research and innovation ability. Forming part of the core patent technology through independent innovation, key technology to countries in need of industrialization, establish and perfect the technology innovation system and industrial clusters, forming a semiconductor such emerging industries in China with international competitiveness.

Preferential policies should be introduced

At present, China's semiconductor lighting industry in support policies, support and personnel training have a certain emphasis on, but on the whole, and other pillar industries there is a big gap. As for the innovation environment, the most urgent is still the problem of talent. Chinese LED industry development started late, there is a shortage of professional and technical personnel, domestic enterprises need to improve the innovation ability of enterprises in the development, must be paid from abroad or from Taiwan professional and technical personnel, so it will undoubtedly improve the manufacturing cost in the development of the industry.

The industry believes that the introduction of the country in terms of the introduction of LED human resources is conducive to innovation and development of some preferential policies, but also to increase the cultivation and output of domestic talent.
