As LED inventor, currently active in the GaN light-emitting components of the first line of Shuji Nakamura (University of California, Santa Barbara), and OLED inventor Jodo Junji (Yamagata University Graduate School of Science and Technology, Professor) attended the discussion , Tokyo Big Sight International Exhibition Centre, the venue packed audience, the venue is almost full house. Tsutomu Ochiai, lighting designer (M & O Design Office Chairman) under the auspices of the participants of the LED lighting and the feasibility and popularity of OLED lighting problems. New lighting in the field of fear “behind closed doors phenomenon” Lighting Fair held every two years, the biggest feature of this LED lighting has become the highlight. First of all, the spokesman of the village and town households, respectively, spoke about his impression of the exhibition venue. Nakamura said: “It can be said more than 90% of the exhibits are the LED lighting apparatus. This is compared to the previous lighting show is very different, surprisingly, not small.” Nakamura in 2 to 3 years ago took part in the lighting at the exhibition in the United States, when only 20 to 30% of the exhibits is the LED-related products, such as the existing main character is a fluorescent light. Nakamura believes that the situation from the white LED R & D point of view, another 2 to 3 years, LED lighting, luminous efficiency of at least 50% higher than the current. “LED lighting will be more and more research. As the LED of the researchers, I am very happy.” Before the panel discussion in the village of personal speech that: “the next 2 to 3 years is likely to achieve luminous efficiency of 200 ~ 250lm / W”. City households impression is: “4 years ago, mostly fluorescent site, 2 years ago, budding LED lighting, LED this year is as if into a show.” The progress of LED lighting technology fast, people are “beyond the challenge of non-OLED lighting.” City households in the panel discussion before the personal speech that, although in the light-emitting OLED lighting efficiency and longevity have made solid progress, but compared with the white LED, R & D 2 ~ 3 years later. Turning to the rapid progress of LED lighting technology, while the city family also pointed out the concerns of the business model. LED lighting in the Japanese market, “behind closed doors on the emergence of the phenomenon.” Indeed, the white LED technology originated in Japan, but Japan’s lighting manufacturers “can not attack the overseas market” (City households). Limited in Japan because the Japanese market, the development of different global markets, the results lost their ability to compete in the global market, or to attack the global market had to change product specifications, the situation is worrying. Japanese mobile phones have appeared in the “behind closed doors phenomenon” is likely to be repeated in the LED lighting. Nakamura pointed out that the United States due to the risk of the development of LED lighting company. Progress in both R & D or business decisions very quickly. Taiwan and China is also the case. However, the development of the Japanese LED lighting, “by large companies responsible for slow decision-making” (Nakamura), the technology level of other countries will sooner or later catch up with Japanese firms. In addition, Nakamura also said that Japan’s various provisions too, hindered the development of LED lighting to improve the speed. “Not to abolish the requirement will not create free competition” (Nakamura). Avoid derailment of the global market Ochiai moderator pointed out that LED lighting business in Japan is not just a problem behavior occurs behind closed doors. In addition to LED lighting, Ochiai OLED lighting also has the experience, and understand the situation of overseas opportunities for LED lighting more. Ochiai said that based on these experiences, can be said in LED and OLED components and equipment such as hardware, Japan has achieved the world’s most sophisticated level, but allow more people to enjoy the fun of the application level of lighting development, Japan has over Europe and the United States lack enthusiasm. This in the village, said: “This is because the white LED from the traditional development of Japanese firms, while the traditional Japanese lighting manufacturers are to achieve product of.” If you use LED lighting, you can achieve colorful lighting design, computer software can easily control color and brightness. In this way there will be dramatic changes lighting, LED lighting will be different from the existing culture of the new lighting product. Therefore, in addition to hardware, LED lighting software (Note: This means the use of skills) is also essential, otherwise the field of LED lighting, “Japan will derail the global market” (Nakamura). In addition, the city of households that: In order not to derail the global market, the standardization of hardware and software is essential. Many people think that, now listed on the standardization of LED lighting has come to an end. However, the practical OLED lighting has only just begun, “I hope that the standardization of OLED lighting can be born in Japan, and successfully develop” (City households).
