Reduce Variation

This project plans to remove one of the major barriers to the adoption of high-efficiency LED lighting -- namely, the difficult of providing low-cost white light that has consistent color quality and brightness. Current practice is to separate LEDs according to color during the manufacturing process in order to maximize product yield. Unfortunately, this creates variation in light output and color quality of the product, leading to reduced performance and increased costs. KLA-Tencor seeks to improve the color consistency of LEDs by utilizing a measurement tool during manufacturing that reduces the variation in LED quality, improving performance and reducing cost.
