LEDs are getting better, much better
Abstract:
Various Japanese companies have been busy behind closed laboratory doors to enhance LED lamps, according to Japanese newspaper Nikkei. Companies such as TechInTech Co. or Scivax Corp. are looking for ways to make brighter LEDs that use less power and can be sold for a lower price.
Scivax Corp. used nanotechnology wizardry to create dents on a sapphire substrate. The dents, which are merely 150 nanometres deep, keep the light shining in one direction.
TechInTech and its parent company Dainippon Screen Mfg. have teamed up with Scivax to sell manufacturing equipment for the nanodented substrate to LED makers some time early next year. According to the report, the equipment will cost somewhere in the range of 1.8 to 5.9 million dollars and can be used with existing production lines, meaning no other investments are required.
