Nakamura Shuji talks about the future development trend of LED, and the three fields are optimistic.
In recent years, general lighting equipment has gradually entered a stable period, and the interest rate of the LED industry has been declining. Enterprises have begun to expand into the emerging blue ocean market. Nakamura Shuji, who won the Nobel Prize in Physics for researching blue LEDs, was released at the Academia Sinica in Taiwan yesterday (8). The speech said that including Micro LED, laser lighting and lighting technology (LiFi) will be the future development trend of the LED industry. Currently working at Nakamura Shuji of the University of California, Santa Barbara, in 2014, he won the Nobel Prize with two Japanese scholars, Akasaka Yoshi and Amano, and the official award was due to the invention of an efficient blue light-emitting diode. A bright, energy-saving white light source. Nakamura Shuji was elected honorary academician of Taichung Institute last year. He was awarded a badge by Liao Junzhi, president of the Taichung Institute of Science and Technology, and delivered a speech yesterday. Nakamura said that the luminous efficiency of LEDs is more than 10 times that of incandescent lamps, which can greatly reduce energy consumption. According to current statistics, LED lighting can replace traditional lighting. If it is in Japan, it can save 7 nuclear power plants. Volume; 19 in the United States; about 17 in China. And LED life span of 30 to 50 years, can provide stable lighting for a long time, there will be no recycling problems in the short term. For the current LED market seems to be saturated, profitability is declining, many companies want to find out where the next blue ocean is. Nakamura said that MicroLED, laser lighting and lighting technology (LiFi) is the future direction of LED development, but he also said that it will take time to overcome technical limitations and popularization. Nakamura Shuji mentioned in the press conference after the meeting that LED has been developed so far, and there are many applications that he did not expect at the beginning. For example, there are scholars at Taichung Institute to isolate cancer cells. Now he is fully committed to laser lighting research, and the related applications are still in their infancy. At present, only the headlights can be seen in life, but he believes that there will be opportunities in the future and can replace LEDs. Another technology that is being looked at by Nakamura Shuji is the wireless optical communication technology Li-Fi, which uses LED or laser as the medium for data transmission. In the near future, the lights in the office will be base stations, projecting indoors, allowing computers and home appliances to connect to the Internet. Nakamura said that the use of LED Li-Fi, transmission data is 10 times faster than Wi-Fi, laser Li-Fi is hundreds of times faster. Another key point is that Wi-Fi has a bandwidth limitation. There are too many people in a certain area. Uploading and downloading will appear very card, and Li-Fi is not limited. Nakamura said that Taiwanese may feel that Wi-Fi is very good, but the future of Li-Fi will make the transmission faster and download movies. In densely populated areas such as urban areas in mainland China, Li-Fi will be a great boon.
