Patents Assigned to BRIGHT CRYSTALS TECHNOLOGY, INC.
  • Patent number: 8932887
    Abstract: A method for manufacturing an LED (light emitting diode) with transparent ceramic is provided, which includes: adding quantitative fluorescent powder into transparent ceramic powder, wherein the doped ratio of the fluorescent powder is 0.01-100 wt %; preparing the fluorescent transparent ceramic using ceramic apparatus and process, after fully mixing the raw material; assembling the prepared fluorescent transparent ceramic and a semiconductor chip to form the LED device. The method assembles the fluorescent transparent ceramic and a semiconductor chip to form the LED device by replacing the fluorescent powder layer and the epoxy resin package casting of the traditional LED with fluorescent transparent ceramic. The fluorescent transparent ceramic is used as the package cast and fluorescent material, and the LED device manufactured through the method has more excellent performance.
