According to market research firm SBI (Specialists In Business Information), It is  estimated that the market size of global LED lights and OLED today has more than 5 billion U.S. dollars, while the United States occupies a market value of $ 1,000,000,000. The SBI further Estimated that the market size of Global led and the OLED in 2013 will reach $ 14 billion, while the United States is up to $ 3 billion market size.

Why led and OLED technology can become one of the best industry in the future in potential growth? Because the efforts made on the current global green energy is more even than ever. This is influenced by the oil and other rising prices and the global climate change in the first half of 2008.

Compared to the traditional incandescent. Led is of much efficiency on the energy conversion. Generally speaking, the LED conversion efficiency is 80%, but the incandescent is 20%. For example, the energy use can be reduced to 92% if using led traffic signals instead of using incandescent traffic signals.

From a long point of view, many places around the world will no longer need to build too many power plants if more and more LED and OLED application markets are established, even if more and more people are in higher demand for electricity. This is because LED and OLED can reduce everyone’s electricity consumption. So once the higher the penetration rate of led lighting bulbs, the existing power plants is enough to meet demand.

However, SBI also reminds that the cost reduction still need some time even if there are many advantages of LED and OLED.

Therefore, one of the keys is to hinder the popularization of LED and OLED cost. Once the rapid price declines, and perhaps LED and OLED market scale will be larger and more popular.

Taiwan is now also actively working to develop led lighting bulbs market. Ministry of Economic Affairs Energy has enlisted NT 2-300000000 yuan budget. After the LED street light is set, it will expand the replacement of LED street lights. LED inside estimated that the overall LED market in Taiwan will have 400-500 billion opportunities.

Semiconductor lighting industry has become the industry heights of the post-crisis era. For basic research in Chinalags behind the technology, market development phenomenon, experts called for.

Due to the huge application requirements, the semiconductor led lighting bulbs market appears market leading technology development, technology research ahead of the characteristics. Recently, the basic research on relate topics held at Xiangshan Science Conference, Nanjing University Professor Chang Yung and other experts pointed out that China’s semiconductor lighting basic research received certain support in the past 10 years, but there still exists absence. The early accumulation of the basic research cannot adapt to the rapid development of the semiconductor lighting technology needs. Thus, accelerating the study of a lot of basic scientific questions of the semiconductor lighting technology and solving the technical bottleneck of industrial development is imminent.

Semiconductor led lighting bulbs, are widely regarded as the second revolution of the lighting in the history. Luminescence is completely different with the traditional lighting. It is not only with a safe, no strobe features, but also there is no infrared and ultraviolet radiation which does not cause two secondary contamination. “the Chang Yung introduction.

“According to the theoretical expectations, semiconductor lighting luminous efficiency can reach 400lm / W which is 3-4 times compared with the expected efficiency of energy-saving lamps.” Researcher Zeng yiping at the Institute of Semiconductors, analyzed that: If the semiconductor led lighting bulbs source luminous efficiency 200lm / W or more, it can replace our traditional lighting source which can at least make our country lighting electricity annual savings of more than 1/3.

Reporters learned from the meeting, the current level of international semiconductor lighting products has reached 100lm / W, and the level of our industry has more than 80lm / W, which is over luminous efficiency of led lights.

“In China, We should strengthen our support in the field of basic research ” Zhang rong said that currently 100lm / W luminous efficiency to 200lm / W, the efforts of a number of years, basic research needs to be further breakthrough. “
