Langlada: Deep ultraviolet LED devices help COVID epidemic prevention and control
The China National Natural Science Foundation briefly released the results of deep ultraviolet LED devices independently developed.
Deep ultraviolet light can efficiently kill most viruses and bacteria, including the "new crown", but deep ultraviolet light-emitting diodes (LEDs) face the bottleneck of low luminous efficiency.
Through continuous research, Chinese scientists have independently developed high-efficiency deep ultraviolet LED devices, which can kill 99.99% of the new coronavirus within 1 second, effectively helping the precise prevention and control of the epidemic COVID.
In order to solve the worldwide problem of low luminous efficiency of deep ultraviolet LEDs, the team improved the luminous efficiency of deep ultraviolet LEDs by developing new substrate materials and their growth methods, and developing new electron blocking layer materials. High-efficiency deep-ultraviolet LED devices between 280 nm.
After expert demonstration, it is believed that the deep ultraviolet LED related disinfection solutions and products meet the disinfection needs of air, water and object surfaces and other related scenes and the photobiological requirements of coexistence of humans and machines, and can disinfect the environment in the presence of people.
Compared with the traditional mercury lamp irradiation, deep ultraviolet LED disinfection products are ozone-free and can be started and stopped instantaneously. Together with the relevant control system, they can be opened when people leave and stop when people come, which fills the domestic deep ultraviolet LED technology products. Technical gaps in public health security and scientific and technological epidemic prevention.
