Chisaki Yoshi, Amano Hiroshi and Nakamura Shuji have won the 2014 Nobel Prize in Physics for inventing high-brightness blue LEDs. The entire LED industry, experts and scholars are excited. Insiders pointed out that it brings not only the lighting revolution, but also the substantial acceleration of the LED industry process. In the future, the application of blue LED will usher in explosive growth. Bringing the second lighting revolution LED industry ushered in an outbreak. The three scientists exported blue light beams through semiconductors in the early 1990s, which brought a fundamental change in the development of the lighting field. The Blu-ray LED is known as the second lighting revolution after Edison. Before the invention of the LED blue chip, white light could not be specifically applied to the field of illumination. The emergence of blue light is the era of LEDs entering the large-scale application stage of home, road outdoor and landscape, and subverting the era of incandescent lamps and energy-saving lamps. The world has reduced carbon emissions, saved energy, and is more conducive to environmental protection. Li Xuliang, former chairman of Qinshang Optoelectronics, a listed company in the domestic lighting industry, told reporters that blue LEDs can save 60-70 energy and are a major contribution to humanity. At present, the basic application of LEDs on the market has 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 completely replace traditional lighting products. It is this development background that makes the impact of LED on human life deeper, and the role of LED for people is increasingly valued globally. According to industry insiders, in addition to the high-efficiency energy-saving and emission-reduction expectations of blue-light LEDs, it is more important that the industry's progress is much faster than the early assumptions, making a variety of LED applications extremely large in just over a decade. Changed the life of human beings. China's LED industry is firmly ranked as the world's No. 1 enterprise competition has intensified the decline in gross profit margin. In fact, in terms of blue LED technology, China is far less advanced than foreign countries. It has been developed abroad for decades, and domestic research and development has only been a few years. Despite this, in China's short development time of less than ten years, the scale of the domestic LED market, application innovation and quality control have been far ahead in the world, and the first place to sit. Li Xuliang told the People's Daily reporter that even some netizens joked that this blue LED won the Nobel Prize, and the Chinese LED industry should be the fourth person to win the award. 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 cycle. At present, there are many enterprises in the domestic LED lighting industry, and the competition is fierce. The expansion of production capacity and product homogeneity have caused price wars, and the product gross profit has gradually declined. Among the lighting industry companies currently listed, Qinshang Optoelectronics' 2014 semi-annual report shows that the company's total profit is 67.772 million yuan, a year-on-year increase of 5.69, while the gross profit margin has decreased year-on-year; Foshan Lighting's profit from last year decreased by 37.12 year-on-year to the first half of this year. Against the trend rose 71.51. Li Xuliang believes that lighting companies need to continue to innovate to deal with the industry competition. In the future LED industry, lighting may only account for 10-20 functions. The more powerful functions may be due to its intelligent, Internet-based and many other functions. The integration of multiple application technologies is the future of LED lighting. .
