Fireflies Inspire More Efficient LEDs

Optics & Photonics News- by Sarah Michaud - 02/27/2019
Researchers from Penn State University, USA, have drawn inspiration from the glowing bellies of fireflies to design a more efficient light-emitting-diode (LED) bulb (Optik, doi: 10.1016/j.ijleo.2019.01.043). The design includes asymmetrical micropyramid structures, similar to those found on the surface of a firefly’s glowing abdomen, etched onto the outer surface of an LED.
