OLED lighting inventors on the development of future – Mosaic texture – Marble t
To LED and OLED lighting will create a future seminar on the theme of light in Tokyo's "LightingFair2009" on the held. Blue 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, and the participants of the LED lighting and the feasibility and popularity of OLED lighting problems.
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 families, said: "4 years ago, the venue mostly fluorescent, LED lighting 2 years ago, budding, this is as if into LED development." 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 households that the city had concerns about 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" and therefore technical 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.
Moderator Ochiai said the Japanese LED lighting business 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, use of calculators can be easily controlled by software 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, in the village that "Japan will derail the global market." 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, the city have expressed "hope that the standardization of OLED lighting can be born in Japan, and successfully develop."
