  • Method for manufacturing LED with transparent ceramics
    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.

  • Luminous faceplate of color projection cathode ray tube and substrate for manufacturing the same
    Patent number: 6489715
    Abstract: The present invention relates to a substrate of a luminous faceplate of a color projection cathode ray tube and a luminous faceplate which is composed of this substrate. The substrate consists of transparent polycrystalline material, and the luminous faceplate comprises a transparent polycrystal substrate and a luminous layer which is formed thereon. The luminous faceplate using the substrate of the present invention has an advantage over the prior art in the volume of a product, operating power, manufacturing cost, and resolution and so on. Thus, it is widely used in the field of color projection TV, advertisement display and so on.
