Solving the problem of LED glare and low luminous efficiency by using the point of view

A new type of material, the light diffusion coating, was developed in World Expo by the team of Fudan University. The material can effectively solve the problem of low glare and low luminous efficiency of LED light source.

It is understood that there are many imperfections in the current LED, the most fatal drawback is that the characteristics of its point light source. LED light will produce a strong light, can not be used to look directly at the eyes, if you have been living in the high brightness of the LED light source, LED light source formed by the strong light will instantly affect visual judgment. In the short term will produce eye discomfort and fatigue, and long-term use will produce permanent damage.

In order to avoid the production of LED light pollution, travel wave light diffusion film research professor of the LED point light source is converted into a uniform surface light source, so that the formation of diffuse light, so as to achieve uniform light effect, so that the overall light is more uniform, soft and full. Reporters learned that 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. Once the number of lights, LCD screen power consumption and heat generation will be significantly reduced, for green help. LED light diffusion coating, can replace the diffusion film currently in use, to eliminate glare and point light source LED device, can be used for outdoor lighting, traffic lights and large size LCD panel and notebook computer backlight, architectural lighting, automotive lighting, home lighting etc..
