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. “
