White LED need to learn technology heritage experience red LED is a shortcut to achieve 100lm/W

[Nikkei BP news] white LED technicians now can be described as full of energy. Luminous efficiency, the current row in the world is the first CITIZEN electronics, has reached 70lm/W. Before and after 2010, the luminous efficiency will be raised to 100lm/W dream is also possible to achieve. Other manufacturers are also eager to catch up with CITIZEN electronics, no one doubts the possibility of the realization of 100lm/W, the focus of attention has been transferred to when, who will be the first to complete this breakthrough. The industry also predicted that if successful, then 2008 years will be able to achieve this goal, we can see the pace of development of white LED technology.

R & D line of technical staff is excited about technological progress is directly related to the growth of the market. The higher luminous efficiency, the wider the scope of application of white LED. That is to say, it is possible to build a virtuous cycle of expanding sales through technological advances. It is precisely because of the huge potential demand that researchers are so dedicated to the development of technology. Technical staff of white LED may be in an excited state at present, and this kind of excitement may of mature technology in the field of difficult decision to experience.

A white LED developer has said: "I would like to listen to the views of red LED developers." The reasons are as follows: Although the future of white LED bright, but the need to solve the technical issues are also piling up. At the same time, solutions to these problems are emerging. In other words, the white LED in technology development is not suffering from no countermeasures, but because of the hands of too many pieces, do not know which to choose a good. As a result, young technicians now want to learn about the history of the development of red LED. Of course, red LED and white LED are two different technologies. However, when the technical personnel of the red LED why upset, considering what the problem is, according to what to choose the solutions of these ideas and technical personnel now white LED is similar. The technical staff believes that the process of technological development, although documented, but can really become a useful clue to the thinking of the technical staff. Unfortunately, the white LED emerging companies are not all in the field of red LED achievements of the enterprise. Moreover, the flow of talent in Japanese companies is not enough. If you set up a system beyond the boundaries of the enterprise to "inherit" past experience, then the white LED technology development work may be a big step forward. Deeply realized the importance of technology inheritance. (reporter: Asami Naoki, "Nikkei Electronics" editor in chief)
