Diode surface changed to improve the LED Light efficiency

In recent years, LED displays have become closer to people's daily lives. LED display has the advantages of high definition, large visibility, and strong flexibility. It is widely used in advertising media, school teaching, art exhibitions, home theaters, wedding events, and other occasions. For example, when advertising is played, the LED display screen can show dynamic advertising content to customers, and businesses can also change the playing content at any time according to their needs. If it encounters foggy weather, the LED display can also penetrate the dense fog, allowing more people to see it. Therefore, the use of LED display screens to play advertisements has gradually replaced traditional advertising boards.

Diode surface changed to improve the LED Light efficiency

It’s reported that a PhD of New York Rensselaer Polytechnic Institute developed a new manufacturing LED – to change the design of the diode surface. The method is creating thousands of tiny star-shaped pillars on the surface, these stars are specially designed by 5nm layer; it aims to help disseminate the light.

The PhD named this nano-structured gradient index (GRIN) structure. New method can generate more light, reducing the impact on the environment and the overall cost. The doctor said compared with traditional light, LED lamp has advantages like light weight, high efficiency, green and recyclable, but the actual efficiency is not high as its theoretical value, if people can increase the light output, the light efficiency will be improved effectively.
