Siberian researchers offer technology to upgrade LEDs

Scientists in Novosibirsk, in Siberia, have developed a new LED production technology which is said to be able to make LED-based lamps brighter, less costly, and more eco-friendly

Scientists in Novosibirsk, in Siberia, have developed a new LED production technology which is said to be able to make LED-based lamps brighter, less costly, and more eco-friendly, Novosibirsk News reported. Researchers from the nanosystems and optical engineering chair at the Siberian State Geodesic Academy (SSGA) are reported to have come up with a way of simplifying LED manufacture processes. At the heart of the method is laser-aided perforation of the LED crystal, the key diode component that generates light. The surface of a crystal needs to be perforated to prevent light reflection inside the LED, the project developers at SSGA explained. Today, crystals are typically perforated with optical waves and chemical reagents, a technique that makes LED production a time-consuming and labor-intensive process. The new Siberian technology will help both simplify and step up LED manufacture, the scientists believe. They are currently seeking a Russian patent for the SSGA solution and are ready to polish and refine it for future commercial production as the effort unfolds...
