What will laser lighting replace LED lighting in the next decade?

Laser illumination is divided into visible laser illumination and infrared laser illumination. Visible light laser illumination is divided into the following two according to the principle: 1) blue light excitation phosphor to achieve white light illumination (such as the laser headlights introduced by a BMW model in 2014); 2) red, green and blue laser synthetic white laser, or true color light Lighting (such as the laser lighting of Qingdao Zhongke Spectrum). Infrared on June 25th, as the benchmark for LED lighting, Nobel Prize winner of the 2014 Nobuo Physics Award attended the 2016 Chengdu Global Innovation and Entrepreneurship Fair in China. In an interview with the media, he may say something Brighten the future for Chinese LED companies. Nakamura Shuji boldly predicted that laser lighting will replace LED lighting in the next decade. Who is Nakamura Shuji was born on May 22, 1954 in Izumi-cho, Japan. He graduated from the University of Tokushima, Japan, a Japanese-American electronic engineering scientist, and a professor of materials at the School of Engineering, University of California, Santa Barbara. Nakamura Shuji was widely known for his development of high-brightness blue LEDs based on GaN during his tenure at Nichia Corporation in Japan in 1993. At the time, the development of a blue LED was considered impossible, with only red and green LEDs in the previous 20 years. On October 7, 2014, Akasaka, Amano and Nakamura received the 2014 Nobel Prize in Physics for the invention of high-efficiency blue LEDs. What is laser illumination? Laser illumination is divided into visible laser illumination and infrared laser illumination. Visible light laser illumination is divided into the following two according to the principle: 1) blue light excitation phosphor to achieve white light illumination (such as the laser headlights introduced by a BMW model in 2014); 2) red, green and blue laser synthetic white laser, or true color light Lighting (such as the laser lighting of Qingdao Zhongke Spectrum). Infrared laser illumination, mostly used for night vision, night camera monitoring lighting. Laser lighting will replace LED lighting in the next decade. With overcapacity and increasing competition, many LED companies in the country have encountered bottlenecks in their development. On June 25th, as the benchmark for LED lighting, Nobel Prize winner of the 2014 Nobel Prize in Physics attended the 2016 Chengdu Global Innovation and Entrepreneurship Fair in China. In an interview with the media, his words may be China. LED companies light up the future. Nakamura Shuji boldly predicted that laser lighting will replace LED lighting in the next decade. The efficiency of laser illumination is thousands of times higher than that of LED, which not only increases the projection distance, but also improves safety, while being smaller and more compact. In addition to the field of lighting, laser display will have a wider application in projectors, digital cinema, television, stage lights, large screen splicing, automotive and other fields. Nakamura Shuji believes that there is no problem with a laser light that covers an area of ​​100 square meters. But because the laser is now too expensive, the application rate is not high, but the future is a big trend. When talking about the problem of Chinese LED companies being forced to transform or even close down in recent years, Nakamura said that many Chinese LED companies have serious homogenization problems and lack of advantages in competition. Just like Chinese steel companies, overcapacity will This has led to a decline in prices, and in a freely competitive market, a natural elimination mechanism has emerged. The name of the company changed its name. The renamed enterprise is mainly packaged enterprises, including Hongli, Changfang, Lehman, and Jingke. In addition to Jingke, the renaming of the other three packaging companies is due to changes in corporate business, Hongli cross-border Internet of Vehicles, Lehman cross-border sports, and the long-term extension of operations to financial and mobile lighting. This just confirms Mr. Lin Jiliang, executive general manager of Mulinsen, on the development of the packaging industry. He said that the bottleneck encountered by LED in upstream technology is that the breakthrough space for light effect performance is already small; in the midstream, the industry is gradually integrating, and many listed LED packaging companies in China are also making adjustments and transformations to education and sports. In the downstream sector, the growth of LED applications is mainly due to the small-pitch display and the alternative market for lighting. LEDs became popular in 2014. 2014 is the year of popularity of LED lighting. From the implementation of the new policy at the beginning of the year, to the frequent occurrence of integration, mergers and acquisitions, and the rush of the road, the scale of the industry has continued to grow, the integration and concentration of the industry has promoted the continuous breakthrough of technology, and the penetration of the LED lighting market has become a global LED lighting market. An important pole in the process of upgrading and upgrading the lighting industry. According to industry forecasts, in 2015, the domestic LED industry is encouraged by the government's policy, the annual growth rate of the market is better than that of developed countries. In 2015, it will reach 46.5% and the market size will be 4.57 billion US dollars. The output value of LED lighting is expected to be Exceeding the output value of traditional lighting has become a turning point in the lighting industry. In 2015, LED companies were eliminated by 30%-40%. In 2015, the competition in the LED lighting industry will become more intense, and the industry pattern will gradually emerge. Dou Linping, secretary general of the China Lighting Society, predicts that the LED industry will present four major development trends in the future. First, the industry has experienced high growth, but most of the companies have not achieved simultaneous growth with the industry. Only some high-quality companies have performed well. Second, in 2015, The LED industry competition will be more intense; third, after 3 years, only 5,000 LED lighting companies can stay; fourth, LED companies must survive, must explore market segments, identify their own positioning, differentiated parties Can win. Through interviews, many industry people also agree with Dou Linping's thoughts. They believe that lighting companies will be eliminated by 30%-40% in 2015, mainly due to the overcapacity of LEDs in the previous two years, which triggered the vicious price competition between enterprises. The prices of downstream enterprises' products have been declining, profit margins have been severely compressed, and 70% of lighting companies are facing the fate of capital breaks and being eliminated. The difference between LED illumination and laser illumination LD laser and LED light are not much different from the excitation source. The YAG laser consists of one more laser radiation. The LED adds a fluorescence conversion after the semiconductor excitation light. The main visual The difference is that the monochromaticity of the laser is very good, the light of the LED is wider, suitable for screens, illumination, etc., the brightness is also incomparable, because the directivity of the laser is very strong, it is linear light, if not processed, the brightness is higher than LED is much larger, laser RGB visual effects are still immature, only stay in the laboratory state, laser projection, laser TV, just a concept, the harm of laser is mainly for the eyes, the power of a little laser direct eyes will be instantaneously penetrated The retina causes blindness, and nothing else harms it.
