It is reported that the high-power and high-brightness LED chips of the scientific and technological projects in Jiangsu Province have made important progress. The first batch of prototype samples have been put on the line for 1000 hours of performance testing.
It is understood that the project was undertaken by the Physics College of Yangzhou University. The first batch of prototype samples have been on-line for 1000 hours of performance testing. This new light source chip independently developed by China will be used to replace similar foreign products. According to Professor Zeng Xianghua from the School of Physics of Yangzhou University, the research team consisting of 10 researchers from the Optoelectronic Research Center of the institute cooperated with Yangzhou Huaxia Optoelectronics to carry out school-enterprise cooperation to redesign the structure of domestic chips and focus on solving the heat. Large stability, fast decay and other stability issues to improve their service life.
The chip is the "brain" of LED, but at present, China's LED chips are weaker than imported chips in terms of life, brightness, and cost performance, resulting in high cost of final products, which is difficult to popularize among ordinary consumers, and chips for high-end products need to be imported. . Zeng Xianghua said that the first batch of new chip samples have been successfully trial-produced and have obtained three national patents. After 1000 hours of continuous charging test, the researchers will also improve the details, and the stable life of the new chip can be increased to 50,000. More than an hour. The new chip is likely to be independently developed by China, which will greatly reduce the cost of LED manufacturing and eventually replace the imported chip.
