A design inspired by the firefly's lantern could lead to brighter and more efficient LED lighting.
The team of South Korean scientists based their new design on the multiple layers of the firefly’s lantern. Using a scanning electron microscope and numerical analysis, they discovered that the highly ordered structure of the lantern acts as an anti-reflective layer, reducing the loss of light and increasing efficiency.
Currently, manufacturing conventional anti-reflective coatings for LEDs is an expensive and multi-step process. However, the new method requires only a single injection molding step, which should reduce costs.
