Light diffusion coating will solve the problem of glare and low light output efficiency of LED light source

April 06, 2023

Recently, Professor Yu Bo, a team of materials science at Fudan University, developed a new type of material, light diffusion coating, which can effectively solve the problem of glare and low light extraction efficiency of LED light source.

It is understood that one of the most deadly drawbacks of LEDs is the nature of their point source. When the LED light emits light, it will produce a strong light spot, which cannot be directly viewed by the eye. If it is always living around a high-intensity LED light source, the strong light spot formed by the LED light source will instantly affect the visual judgment. Eye discomfort and fatigue can occur in the short term, and permanent damage can occur in long-term use.

In order to avoid the light pollution hazard caused by LED, the light diffusion film developed by Professor Youbo evenly converts the point source of the LED into a surface light source, so that the light forms a diffuse reflection, thereby achieving a uniform light effect, so that the overall light source is more uniform and soft. full. The light diffusion film can not only improve the utilization of LED light, increase the brightness of the LED, but also reduce the amount of light used. Once the number of lamps is reduced, the power consumption of the LCD screen and the generation of heat energy are greatly reduced, which is helpful for environmental protection.

In addition, LED light diffusion coating can replace the currently used diffusion film, used to eliminate glare and point light source problems of LED devices, and can be used for outdoor street lighting and traffic lighting, large-size LCD panels and notebook computer backlights, architectural decorative lighting, Automotive lighting, home lighting, etc.
