Blue LED brings lighting**

The news of the 2014 Nobel Prize in physics for the invention of "High Brightness Blue Light-Emitting Diodes" by Akazaki, Amano Hiroshi, and Nakamura Shimura was inspiring throughout the entire LED industry. Industry insiders pointed out that it brings not only the lighting revolution, but also the rapid acceleration of the LED industry process. The future application of blue LED will usher in explosive growth.

Bring the second lighting revolution to the outbreak of the LED industry

These three scientists exported blue light beams through semiconductors in the early 1990s, bringing about a fundamental shift in the development of lighting. Blue LED is known as the second lighting revolution after Edison.

Before the invention of the blue LED chip, there was no way to apply white light specifically to the lighting field. The advent of Blu-ray is a real-time application of LEDs in homes, roads, outdoor and landscape applications. It has also replaced the incandescent and energy-saving lamps. The world has reduced carbon emissions, saved energy, and is more conducive to environmental protection.

According to Li Xuliang, chairman of the LED listed company Qinshang Optoelectronics, the blue LED can save 60%-70% of electricity, which is a major contribution to humanity. Currently, the basic applications in the market are LEDs, which have been widely used.

With the acceleration of the elimination of incandescent lamps and the end of the energy-saving lamp subsidy policy, LED lighting products have gradually become popular and have completely replaced traditional lighting products. It is this development background that makes LED's impact on human life more in-depth, and LED's role for people is increasingly being taken seriously by the world.

According to industry sources, besides the expectation of energy-saving and emission reduction brought about by high-efficiency LEDs, the more important is that the industry's progress is far faster than earlier ideas, making a variety of LED applications significantly more than a decade short. Changed human life.

China's LED industry ranks first in the world

In fact, in terms of blue LED technology, China is far less advanced than foreign countries. It has been developed in foreign countries for decades, and domestic R&D is only a few short years. However, Li Xuliang said, "In spite of this, in China's short development time of less than a decade, the scale of the domestic LED market, application of innovation and quality control have been ahead of the world, sit tight in the top spot."

Even some netizens jokingly claimed that the "Blue LED" won the Nobel Prize and the Chinese LED industry should be the fourth prize winner.

Since 2013, the speed of domestic LED replacement for traditional lighting products has begun to accelerate, and the lighting industry has entered a new round of industrial upgrading cycles. At present, the number of domestic LED lighting industry enterprises is numerous and the competition is fierce. The expansion of production capacity and homogenization of products have caused a price war, and the gross profit of products has gradually declined.

Among the companies listed in the lighting industry at the moment, Qinshang Optoelectronic's 2014 semi-annual report showed that the company's total profit was 67,775,500 yuan, an increase of 5.69% year-on-year, while the gross profit margin was down year-on-year; Foshan Lighting switched from last year's profit drop of 37.12% year-on-year to this year. The contrarian trend rose by 71.51% in half a year.

Li Xuliang believes that lighting companies need to continuously innovate to cope with industry competition.

"In the future LED industry, lighting may only account for 10%-20% of the functions. More powerful features may lie in its intelligent, Internet-based and many other functions. The integrated integration of various application technologies is the future of LED lighting. The charm is."
