Imitation of firefly light structure, LED luminous efficiency increased to 90%
Researchers at Pennsylvania State University (Penn State) have found that the luminous efficiency of LEDs can be improved by replicating the fire-emitting structure of fireflies. Stuart (Shizhuo) Yin, an electrical engineering expert at Penn State University, pointed out that most commercial LEDs currently emit about 50% of their luminous efficiency. How to improve the so-called […]
