This more efficient light source was inspired by the discovery of jagged scales inside the fireflies, which enhanced the glow of the creature. A layer of cover on the LED lamp simulates the function of the scale and reduces the energy required for the LED light. 
The photosensitive material coating on the LED lamp simulates the function of firefly scales, improving energy efficiency and reducing the amount of energy required for illumination.
Annick Bay, a Ph.D. student at the University of Namur in Belgium, said: "The most important direction of this research is that it shows how much we can learn by carefully observing nature." In fireflies, a certain amount of light is The stratum corneum of its outer shell is reflected back into the lantern. But in some fireflies, this reflection can be reduced by the arrangement of jagged scales, which means more light is spilled and the fireflies look brighter.
A layer of coating on the LED lamp that simulates the function of the scales of the firefly not only improves energy efficiency but also reduces the amount of energy required for illumination. Annick Bay said: "We refer to the structure of the edge of the factory roof, because the top of the scales are convex and slightly inclined, a bit like the roof of the factory." There is also an additional benefit, this energy-efficient coating can Applied to current Led Lights.
