LED status and LED supplier policy

LED market battle has entered a new stage. In addition to the previous red, blue light, the white LED technology continues to progress, the application of more expansion in the headlights and general lighting and so on. As the market potential is optimistic, information electronics, chemical manufacturers have invested, trying to erode the market, the sphere of influence of the fierce competition. Nikkei industry news on the current development of LED profiles to do an analysis, as follows.
First, LED industry overview
Japan Electronic Information Technology Industry Association predicted that in 2010 the global output value of white LED will reach 600 billion yen, 3.5 times higher than in 2002. And because the luminous efficiency of white LED has reached the level of fluorescent lamps, so its application areas from the original display, mobile phones and LCD background light source, etc., and in the car headlights, general lighting purposes.
In addition, due to a small, low power consumption, only a specific wavelength and other characteristics, so LED has become an indispensable value for home appliances to enhance the value of the weapon. Although the idea of increasing the composition of vegetables by light has been a long time, but until the emergence of LED to achieve this idea. This is because this idea requires the promotion of photosynthetic light, but does not need to cause germination of light. In other words, the need for brightness, but do not need heat, and only LED can meet this demand. In addition, equipped with sterilization, odor removal effect of the UV LED air conditioners, air cleaners and other products have also come out.
In addition to white LED used as a car, home lighting LED chandeliers, the red, blue LED is also used to cultivate vegetables. Allegedly, the use of LED lighting cultivation of vegetables, the electricity will be reduced to about one-fifth of the past, and the number of days required for vegetable growth can be shortened by about 7%. LED lamp prices are expected to further decline, the use of LED lighting cultivation of vegetables will be in 4 - 5 years after the practical.
Among them, the use of lighting is regarded as the main white LED market, and the industry that more than around 2012, the lighting market will officially take off. If the product surface, many companies have developed luminous efficiency comparable to fluorescent white LED, but the current price is still too high, so still can not immediately universal in the general family. However, the cost of white LED, although more expensive than fluorescent or light bulbs, but there is a long life, can save the replacement time and so on. From the overall cost of environmental protection and maintenance to consider, it is expected that white LED lighting applications will start from the enterprise and public use. In addition, based on power, durability and other considerations, automotive lighting manufacturers have begun to use LED as a lamp.
Second, the supplier policy
In view of the increasingly broad application of LED market, some LED chip manufacturers, the recent action frequently, and significantly change the direction of the strategy. First of all, a Japanese company quietly developed a unique concept of LED technology, in view of the desire to expand the use of LED, the introduction of thermal technology and other technology has never been very important, the company changed the past closed route, Including Japan and the United States and Europe have always been in the opposite relationship between the cross-licensing agreement to obtain the European and American enterprises in lighting, vehicle parts and other related patent rights.
And in the metropolitan area of Okinawa City to build a new R & D center. Yokohama's current technical staff, although only about 20 people, but the new R & D building is completed, will be able to accommodate 150-250 personnel. The reason why the company in Okinawa to expand the scale of R & D, because it is necessary and the automotive, home appliance manufacturers to strengthen the relationship between the escort.
The company in the application of intellectual property rights strategy, although a change in the past closed policy, instead of focusing on cooperation with Japan and the United States and Europe enterprises, but for Taiwan, South Korea and other Asian countries, manufacturers are tough defense line, trying to patent protection , Korean manufacturers in the LED field to further take a big step. In addition to locking the Taiwanese LED manufacturers, the company is actively engaged in a variety of confrontation strategies, and from the road surface for anti-blocking, including with a number of US electronic parts business agreement, requiring these companies do not sell the problem of LED products.
