The Rio Olympics are in full swing recently, with countries sending their top athletes to compete, and China's Fu Yuanhui has qualified for the final by finishing third in the semifinals.

On August 8, Shenzhen Liyang Optoelectronics Co., Ltd. was officially listed and traded in the National SME share transfer system, stock abbreviation: Liyang Stock, stock code: 838452.

With the rise of the third generation of semiconductors represented by GaN and SiC, high-efficiency high-power LED as a semiconductor light source, compared with traditional lighting sources, more energy saving, longer service life, lower voltage, and shorter opening time. High-power LED technology has developed rapidly and has a very broad application prospect, and the reliability of the device is the guarantee of its wide application.

In recent years, with the continuous deepening of research on semiconductor luminous materials, the continuous progress of high-power LED light source manufacturing process and the development and application of new materials (nitride crystals and phosphors), ultra-high brightness leds of various colors have made breakthroughs, which makes it possible for LED applications to span the high-efficiency lighting source market. However, the development of LED lighting system is largely affected by heat dissipation problems, for high-power LED, heat dissipation problem has become a bottleneck problem restricting its development.

The U.S. Department of Energy (DOE) recently released new requirements for LED LAMPS that will take effect on August 1.
