Low added value has become a "heart disease" in Taizhou LED manufacturing industry
On October 7, three Japanese scientists won the 2014 Nobel Prize in Physics for inventing the "High Brightness Blue Light Emitting Diode". What is a "light emitting diode"? In fact, we are no stranger, its English abbreviation is LED. Nowadays, LED lights and LED landscape lights are familiar to us. It is the research of these three scientists that invented blue LEDs, which made bright and energy-saving white LED light sources possible. However, do you know that letting LED products enter thousands of households, "Taizhou manufacturing" is indispensable.
Taizhou LED lights made in China <br> <br> important after the emergence of blue LED, white light is widely used in lighting, LED into the real large-scale application of daily household and outdoor landscape. In terms of LED lighting and other applications, Taizhou has a pivotal position in the country.
“The LED lighting fixtures produced in Taizhou occupy a certain proportion in China. If it is a holiday lantern, it may account for a higher proportion in the country. In the application development of LED products, Taizhou has created a lot of force.†Zhejiang Feitian Mr. Guo, a technician at Lighting Technology Co., Ltd. said.
Although the number is dominant, Mr. Guo believes that Taizhou is still not a big LED industry.
"The LED industry chain is mainly composed of five parts: substrate material fabrication, epitaxial wafer production, chip preparation, packaging and downstream application product production. Taizhou's LED production is still at the end of the industrial chain, mainly for the production of downstream applications." Mr. Guo Say.
"Compared with red and green LEDs, the production process of blue LEDs is much more difficult than the other two colors, mainly requiring gallium nitride materials as the substrate of the epitaxial wafer, and gallium nitride is not a natural material, its synthesis It is the technical core of the blue LED chip. As far as I know, most of the chips that produce blue LEDs in Taizhou rely on external 'transfusion', and the chip alone accounts for 30% to 40% of the cost of an LED product." Mr. Guo said .
Product homogenization competition is fierce, and low added value has become a common problem in Taizhou LED product manufacturing industry. The high development cost of the chip and its high requirements for anti-dust and anti-static performance have made Taizhou enterprises unable to do so.
LED will be used in high-tech research and development in the future . It can be said that the emergence of blue LED has completely overturned the era of incandescent lamps and energy-saving lamps. Compared with ordinary energy-saving lamps, blue LEDs can save about 70% of electricity and extend the service life. After so many years of development, the production cost of LED is also getting lower and lower. Therefore, most lighting fixtures on the market currently use LED lights. In the future, more and more families will use energy-saving and environmentally-friendly LEDs during renovation. Light.†Mr. Cai, the head of Huangyan Mingnuo Lighting Co., Ltd., believes that the LED industry will be a sunrise industry.
According to Dr. Liu Yanping, a semiconductor expert at Taizhou University's School of Physics and Energy, LED brings more than just a lighting revolution.
"LED lights are better than ordinary lighting in many performances. For example, as a car light, its response is more sensitive. In the smart field such as mobile phones and televisions, the picture quality can be made clearer. In the future LED industry. Lighting is only a small part of its application. The more powerful function may be its intelligent integration with the Internet, and it is widely used in high-tech research and development."
"If Taizhou wants to get a piece of it, it should cultivate the upstream enterprises of the industrial chain on the basis of the original, do a good job of upstream and downstream industry docking, and convert from low added value to high added value." Liu Yanping said.
â–² Link LED light source has the advantages of energy saving compared with traditional light source. Red LEDs and green LEDs have long been invented, but the long-term manufacture of blue LEDs has become a problem. Without the blue of the three primary colors, it is impossible to obtain a white LED light source that can be used for illumination.
In the 1980s, Akasaki, a professor at Nagoya University, and Amano challenged the global researcher's GaN crystal production. After repeated experiments, in 1986, they successfully made gallium nitride crystals, and in 1989, the world's first realization of blue LEDs.
The Royal Swedish Academy of Sciences said in a press release: "With the advent of LED lights, we now have more durable and efficient alternative light sources."
Because of the low energy consumption, LED lights can be used in many underdeveloped areas relying on local low-cost solar energy. For the world's 1.5 billion people who have not yet benefited from the power grid, this new light source brings a higher quality of life. Although the invention is only "20 years old," it has already benefited mankind.
