LED lights have been around for a long time. There benefit is that they use less power and have a longer life span. A disadvantage of LED lighting is low output. Now there is the technology of nano-imprintlithography. This process can make millions of microscopic holes on the surface of a LED light bulb, increasing the output of light.

A nano particle is an aggregate of particles banded together within a radius between 1 and 100 nm. Nano-technology is the engineering of products at the molecular or atomic level. Nanoimprinting is based on mechanical embossing (stamping process) technologies and can achieve pattern resolutions on nanostructures. A mold containing the nanoscale patterns is embossed on a polymer material that is cast on a wafer substrate. This polymer material is applied at a thickness that allows a fluid to form between the mold’s protrusions and the substrate surface. This creates a cushion that protects the nano features on the mold. This is removed by anisotropic etching, and then pattern definition can be completed.

It will also be used for pattern imprinting on microdrives for Iphones and MP3 players.
