In 2016, the Central Committee of the Communist Party of China and the State Council held the 2015 National Science and Technology Awards Conference in the Great Hall of the People in Beijing. The first prize of the silicon substrate LED technology won the first prize for the industry. An art gallery in the United States announced that it would install a revolutionary lighting fixture for the pavilion to provide visitors with a higher viewing experience. In the high school era, you are only immersed in reading and studying? A student from Huizhou, Guangdong Province designed a two-way lane model of LED lights to contribute to urban traffic congestion. The application of led light source technology is becoming more and more recognized in plant factories. A university in Taiwan claims that the production of cantaloupe in their LED plant factory can reach 8 times that of the greenhouse. There are also LED smart ceiling fans that support Apple's HomeKit protocol, as well as user-friendly applications such as alarm clocks and smart "foot pads" that provide lighting.

The silicon substrate project won the National Technology Invention Award
Recently, the Nanchang Silicon Substrate LED Project won the first prize of the 2015 National Technology Invention Award and was printed in various editions. The sensational effect has been made, so what is the reason for this glory? It is understood that there are currently three international LED lighting technology routes: sapphire substrate, silicon carbide substrate and silicon substrate GaN-based LED technology (ie "silicon substrate LED technology") route. The first two routes are called the mainstream technical route and the “noble†route in the industry, and the core invention patents are monopolized by Japan and the United States respectively. The significance of the birth of silicon substrate LED technology is to open up a new path, so that China has the third international LED lighting technology route, break through the barriers of a new light source, and get rid of patent disputes.
The preparation of high-efficiency gan-based LEDs on silicon has long been a goal of academic efforts. However, due to the large lattice mismatch and thermal mismatch between silicon and gan, the epitaxial film crack, the poor crystal quality, and the low light-emitting efficiency caused by the opacity of the substrate have not been solved for a long time. The silicon substrate gan-based LED route Almost was sentenced to "death penalty." In fact, IBM was developing silicon-based LED technology as early as 30 years ago, but "half-way" announced the abandonment. Chinese researchers are in this situation to "catch up" this technology. After thousands of experiments and continuous technical research, since 2003, the R&D team has finally made breakthroughs, and developed a silicon-based GaN-based LED material and device technology.
National Museum of Art installs revolutionary lighting fixtures
Entering 2016, American tourists will soon be able to visit the Brandiwan River Art Gallery under the new lighting fixtures. According to reports, in order to enhance the visitor experience, the museum all six pavilions will be installed on the new track lighting systems with energy-saving led lights of. Lighting is a key factor in creating the atmosphere of the pavilion in terms of welcoming and providing the best viewing of the artwork. The new LED lighting system will help to increase the flexibility of the different artwork in the various galleries of the Brandy Wanhe Art Gallery, including classic paintings by the Wise artist family and American painter Winslow Homer. Works on slim paper.
It is said that the new LED lighting system can significantly improve the brightness of the lights, even for visitors to see the paintings for the first time. Thanks to the better color reproduction provided by led lights , visitors can truly appreciate the subtleties and tonal range of each piece of art. In addition, the lights help to significantly reduce energy consumption and help the art gallery reduce carbon emissions. The entire lighting project work ended from January 4th to mid-March. This transformative project is funded by funding from CrystalTrust. With this grant, the museum will also create a new audio navigation system.
