Nakamura Shuji and Shiroto Juji -- the first person to talk about LED lighting and OLED lighting development road

LED and OLED will create the future of lighting

As the theme of the lighting seminar held in Tokyo in March 4th 09, held at the Ming International Convention and Exhibition Center Lighting Fair. The inventor of the LED, the blue light emitting component of the first line is currently active in GaN Nakamura Shuji (Professor of California University of Santa Barbara) and the inventor of the OLED city households Chun two (Professor of the Yamagata University Graduate School of science and Engineering Research Department) attended the discussion, Tokyo Ming International Convention and Exhibition Center International venue was packed with the audience, the venue almost All seats are occupied. Under the auspices of lighting designer OLED (M&O design firm), the participants discussed the feasibility and popularity of LED lighting and lighting, etc..

Worried about the phenomenon of "behind closed doors in the new field of lighting"

Lighting exhibition held every two years, this is the biggest feature of LED lighting has become the biggest bright spot. First of all, the spokesman of the village and the city were told about their impressions of the exhibition venue.

Nakamura said: it can be said that more than 90% of the exhibits are LED lighting appliances. This compared with the previous lighting exhibition is very different, surprisingly small". In the village 2 ~ 3 years ago to participate in the lighting exhibition held in the United States, when only about 20 ~ 30% exhibits are LED related products, and the protagonist is fluorescent and other existing light source. Nakamura believes that the development of white LED from the point of view, there are 2 to 3 years, LED lighting efficiency will be increased by at least more than 50%. "LED lighting related research will be more and more. As a researcher at LED, I feel very happy". In the village before the panel discussion in his personal speech, said: the next 2 to 3 years, luminous efficiency is likely to reach 200 ~ 250lm/W". City households impression is: "the fluorescent lamp 4 years ago in the majority, 2 years ago, LED lighting has become this year will make first appearance, LED". The fast development of LED lighting technology, make people feel the non OLED lighting can hold a candle". City households in the panel discussion before the personal speech that, although OLED lighting in terms of luminous efficiency and life has made solid progress, but compared with the white LED, R & D late 2 ~ 3 years.

Turning to the rapid progress of LED lighting technology at the same time, the city also pointed out that the business model concerns. LED lighting market in Japan "appeared the phenomenon behind closed doors". Indeed, the white LED technology originated in Japan, but Japan's lighting manufacturers, but can not attack overseas markets (city households). Because only in Japan, the Japanese market situation and development of the global market have differences, resulting in the loss of ability to compete in the global market, or in order to attack the global market to change the product specifications, this situation is worrying. Once in Japan on the mobile phone "behind closed doors phenomenon" is likely to repeat LED lighting.

Nakamura pointed out that the development of the United States LED lighting benefit from the risk of the company. Whether it is research and development or business decisions are very rapid. The same is true of Taiwan and mainland china. However, due to the development of LED lighting in Japan, "by the large manufacturers responsible for the slow decision-making" (in the village), so the technical level of other countries will catch up with Japanese manufacturers sooner or later. In addition, the village also believes that the provisions of Japan too much, hindering the development of LED lighting speed. "There will be no free competition without abolishing regulations" (Nakamura).

Avoid derailing the global market

The host sochiai pointed out that the existence of Japan's LED lighting business problems arise not only behind the phenomenon. In addition to LED lighting, the fall also has the experience of OLED lighting, understanding the opportunities for overseas LED lighting is also more. According to the experience of Ochiai said, it can be said in the LED and OLED components and appliances and other hardware, Japan has reached the world's advanced level, but to allow more people to enjoy the fun of the development of the application level of lighting, but the lack of enthusiasm than Europe and the United States and japan.

In this village, said: This is because the white LED developed by the traditional Japanese manufacturers, while the traditional Japanese lighting manufacturers in order to achieve product". If the use of LED lighting, you can achieve colorful lighting design, the use of computer software can easily control the color and brightness. As a result, lighting will be a huge change, LED lighting will become a new product different from the existing lighting culture. Therefore, in addition to hardware, LED lighting software (Note: here refers to the use of skills) is also indispensable, otherwise in the field of LED lighting, "Japan will derail the global market (").

In addition, the city pointed out: in order not to derail the global market, hardware and software standardization is critical. Many people believe that the standardization of LED lighting has now come to an end. However, the practicality of OLED lighting has just begun, I hope the standardization of OLED lighting can also be born in Japan, and the smooth development of the (city households).
