LED and OLED who can become the darling of the lighting market?

In recent years, LED as an energy-saving light source and semi permanent cold light source has been widely concerned, its market size has expanded year by year, the rapid growth rate. However, over the years, LED in the mature period has gone too long time on the road, today, in addition to daily lighting and other aspects of LED as a light source there are still many problems need to be solved, and that the LED industry is not at ease, behind the more advanced OLED is rapidly catching up, and at any time there may be LED knocked to the ground.

Intense market competition prospects bright

Data show that in 2008 the global LED application market will increase from $12 billion 500 million in 2004 to $50 billion, the world is currently engaged in a battle to seize the commanding heights of the LED market. Guangdong LED Industry Alliance first president, KingSun chairman Li Xuliang believes that in the fierce competition, China's LED industry needs to improve the capability of independent innovation, integration, full use of existing resources, strengthen industrial supporting and joint research, and through learning and reference, to reach the international leading level.

In recent years, China's LED industry has a certain technical and industrial base, formed a relatively complete industrial chain, the whole industry entered a rapid growth stage of development, market size and future LED lighting is very broad, with an annual growth rate of 50%. But compared with foreign enterprises, the international competitiveness of China's semiconductor lighting industry is still far from enough, shortcomings: one is obviously more dispersed distribution, cluster effect is not obvious; the two industry is small in scale, lack of leading enterprises; the three is the technical level is not high, the larger the gap with foreign countries.

At present, Europe and the United States and Japan and other developed countries on LED R & D and production are very important. Ge, PHILPS, Rahm and other industry giants have also worked with the semiconductor company, the establishment of semiconductor lighting companies, accelerate the global LED market snatch. At the same time, China's domestic enterprises LED production capacity has been expanding trend, foreign investors have increased investment in the country. The type of investment and construction plant is also from the early to the packaging factory to the higher technical content of the chip link. But at this stage, in the epitaxial film production links, Europe and the United States and Japan and Taiwan, China's manufacturers did not invest in mainland China, in addition to Guangzhou Puguang for Hong Kong funded enterprises, the rest of the basic local enterprises. According to CCID predicted that in the next few years, there will be more foreign enterprises to enter the China factories, and local enterprises capacity will be further improved, will become China after Japan, South Korea and Taiwan Chinese area and a LED industrial base.

According to the Research Report of famous market research company ABIResearch released a new show, to the global LED market in 2010 may include two parts: one is a simple and cheap LED, usually in large quantities of procurement market; the other is a high-end, high-tech innovation as the representative of the market. Thus, China's LED lighting industry development prospects bright future.

International enterprise OLED speed LED crisis

Not long ago, said the German NovaledAG market forecast published on OLED, OLED lighting luminous efficiency has reached 50 lumens of /W, is the traditional incandescent lamp 2 times, also said that within two years is likely to achieve 100 lumens of /W target, it will exceed the current standard LED70~80 /W lumens.

High yield at the same time as OLED surface emitting and ultra-thin low cost factors brought about, which is more appropriate than LED as display equipment selection of light source, which makes many LCD panel manufacturers have started to add OLED technology. LED if not in two to three years to solve technical problems, it will be difficult to overcome the catch up after the OLED products, then I am afraid that LED will have no chance.

According to reports, the company developed the OLED technology and the application of organic electronic technology has 4: display, lighting, solar cells, TFT. The company is most looking forward to the field of lighting, Novaled believes that this is a revolution in lighting, is a step by step forward". At the same time, he also pointed out that the world famous lighting manufacturers are in general lighting as the target of development, however, the company believes that "characteristics should first use OLED surface emitting, launched lighting products with novel design, and then spread to the general lighting purposes". In particular, the window of the light-emitting transparent light, in the wall and ceiling paste 10 cm square tile shaped OLED panel lighting is full of expectations. "OLED lighting focuses on the energy efficiency of high luminous efficiency". In addition, Japan, the United States and the European car manufacturers have also strengthened the concern about the use of OLED lighting, is being studied from the inside, the dashboard to a variety of lighting applications.

The day before, OSRAM (OSRAM) optoelectronic semiconductor announce that after just two years of development, has set a laboratory record warm white organic light emitting diodes. Organic light emitting diode lighting device (OLED lighting) the light efficiency can reach 46 LM / W, brightness up to 1000 Candela / m2, life up to more than 5 thousand hours, for the first time synchronization upgrade OLED two key features. In the past, the effect of light and life has been the shift: the increase in light efficiency, shortened life expectancy, and vice versa.

OSRAM Opto Semiconductors OLED lighting technical director Dr. KarstenHeuser for the development of middle reach such results very satisfied, he said: "the light efficiency of new products reached 46 lumens / watt (CIE measurement in the integrating sphere was 0.46/0.42), the service life of up to more than 5 thousand hours, our development team
