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. This biological inspiration can offer new opportunities for increasing the light extraction efficiency of high-power LED packages," they wrote. They noted that the conventional anti-reflection coating of existing LED lights is an expensive process. They said that conventional polymer lenses for LEDs are made by injection molding and then adding an antireflective coating with sputtering. Their method differed. They found that they could produce an anti-reflective plastic lens with just a single-step injection molding process. They said doing so meant driving down the cost of efficient LEDs. Their LED lens was made using a polyurethane-based optical resin. The authors of the study are from the Korea Advanced Institute of Science and Technology, Firefly Institute, Korea Basic Science Institute, and Korea Research Institute of Standards and Science.
Advanced Technologies announced on Oct. 31, that it is streamlining worldwide operations to better align its cost structure with current market conditions and enhance its ability to pursue strategic growth initiatives, including the consolidation of existing business units into a single Crystal Growth Systems (CGS) group and cost reduction actions including an approximately 25 percent reduction of the company’s global workforce.
When fully implemented, the workforce reduction is expected to reduce the company’s annualized expenses by approximately $13 million. GT expects to record restructuring charges associated with these actions in the amount of approximately $4.2 million in the December quarter.
