A new material, optical diffusion coating, developed by the team of Professor You Bo of the Department of Materials Science of the University, appeared at the World Expo. The material can effectively solve the problem of low glare and low output efficiency of LED light source.There are many imperfections in the LED at present. One of the most fatal disadvantages is the characteristics of its point light source. When the LED light shines, it produces a strong light point that can not be looked at directly by the eyes. If you have been living around a high-brightness LED light source, the bright...

The drive power supply of LED lighting lamps requires very high parameters for Transformers and inductors. In order to achieve precision, it takes a lot of manpower and financial resources to achieve it. It is difficult to further reduce the cost of industrial production.For the innovation and breakthrough of LED drive constant current source chip design technology, the new solution can be applied in the actual application of LED lamp drive power supply, the output current is less sensitive to the inductance of Transformers and inductors and the parameters such as LED VF. The key to the innova...
