Nearly 50% of China's traditional light sources are replaced by LEDs

The key technology and industrialization of high-efficiency and long-life semiconductor lighting completed by the Semiconductor Research Institute of the Chinese Academy of Sciences was awarded the first prize of the 2019 National Science and Technology Progress Award in Beijing on the 10th. The first finisher of the project, a researcher from the Institute of Semiconductors of the Chinese Academy of Sciences, Li Jinmin, revealed that at present, nearly 50% of traditional light sources in China have been replaced by semiconductor light emitting diode (LED) products, and a total of about 280 billion kWh of electricity has been saved annually.

Li Jinmin said vividly that the annual power saving is equivalent to the power generation of the three Three Gorges water conservancy projects, and also exceeds the annual power consumption of Australia.

He introduced that LED has the characteristics of high light efficiency and long life. Semiconductor lighting with LED as its core device has been developed as an emerging technology for more than 10 years. It has become the second lighting revolution in the history of lighting after incandescent lamps. LED has a significant energy saving effect, and its electro-optical conversion efficiency is 5 times that of fluorescent lamps and 20 times that of incandescent lamps.

At the beginning of this century, the United States, the European Union, and Japan all proposed semiconductor lighting development plans. In 2003, China first proposed the development of semiconductor lighting plans and started the national semiconductor lighting project. In 2006, semiconductor lighting was included in the national medium and long-term scientific and technological development planning outline, 2013 Officially released opinions on the development of energy-saving and environmental protection industries in 2010, and vigorously promoted the industrialization of semiconductor lighting.

Li Jinmin said that the award-winning project team has formed a complete set of high-efficiency, long-life semiconductor lighting technology with independent intellectual property rights. The project results have achieved large-scale industrialization and promotion. The energy-saving renovation project of the Tang lighting system, APEC summit, Russia World Cup and other major projects have achieved demonstration applications, and the energy saving and emission reduction effects are significant. In addition, China's LED lighting products have been exported to developed countries and regions such as Europe, the United States, and Japan.

He believes that looking forward to the future, the semiconductor lighting industry is changing from the original technology drive to application drive. On-demand lighting, smart lighting, and beyond lighting will be important trends for the future development of the semiconductor industry and will be more widely used in more fields.
