The incredibly resilient and strong structures made by nature are often at the heart of scientific research. Back in 2012, South Korean scientists took observations made of fireflies to make an improved and less expensive LED lens.

The basis of the work is to mimic the bioluminescent organ for lighting apps. The organ’s bioluminescence is used to attract mates. By using a scanning electron microscope and numerical analysis, experiments revealed that the highly ordered structure reduces optical impedance between air and the cuticle, becoming an anti-reflective layer, and minimizing the loss of light while improving efficiency.

The discovery led to an artificial version that was used as a high-power LED lens. The structure of the firefly’s underbelly was the subject of their initial paper, “Biologically inspired LED lens from cuticular nanostructures of firefly lantern,” published in Proceedings of the National Academy of Sciences.

Cuticular nanostructures found in insects effectively manage light for light polarization, structural color, or optical index matching within an ultrathin natural scale. These nanostructures are mainly dedicated to manage incoming light and recently inspired many imaging and display applications

The nanostructures on an LED lens surface were fabricated by using a large-area nanotemplating and reconfigurable nanomolding with heat-induced shear thinning. The biologically inspired LED lens, distinct from a smooth surface lens, substantially increases light transmission over visible ranges, comparable to conventional antireflection coating.

Many would like a cheaper platform for silicon and is now an English Plessey Semiconductor demoed 6 inch Silicon wafers made ​​of LEDs that produce 5 watts of light output.

Plessey manufactured by six-inch reel, which is filled with 4.5 x 4.5 mm 5-watt LEDs. This is essentially a technical demonstration of “silicon led” preparation was demonstrated. Plessey manufactured LEDs emit blue light from 400 to 480 nanometers.
