Abstract: A method for producing sheets of glass phosphor, including following steps of: taking glass powder, phosphor powder and a bonding agent to mix to form a mixture, wherein the glass powder and the phosphor powder are mixed first, and then the glass powder and the phosphor powder are mixed with the bonding agent; compressing the mixture to form a tablet; sintering the tablet to form a glass phosphor body; cutting the glass phosphor body to form at least one sheet body.

Abstract: A method for producing a low temperature glass phosphor lens includes dry mixing a glass material and fluorescent powder to form a powdery or particulate mixture. The mixture is grinded to a diameter of 15-20 ?m, obtaining uniformly mixed glass fluorescent powder. The glass fluorescent powder is hot pressed into a glass phosphor at a temperature of 500-1000° C. The glass phosphor is grinded and polished into a lens. The fluorescent powder can be a fluorescent material selected from the group consisting of yttrium aluminum garnet, nitride, and silicate. The glass material can be selected from the group consisting of a silicate system, a phosphor system, a borate system, and a tellurate system. The glass phosphor includes characteristics of both of glass and fluorescence. The glass phosphor can keep efficiency under the high heat generated by the chip of an LED.

Abstract: A glass phosphor color wheel includes a wheel body made of a glass phosphor formed by sintering a glass material and fluorescent powder. The fluorescent powder is a fluorescent material selected from the group consisting of yttrium aluminum garnet, nitride, silicate, aluminate, and oxynitride. The glass material is selected from the group consisting of a silicate system, a phosphor system, a borate system, and a tellurate system. A method for producing a glass phosphor color wheel includes concentrically placing an inner tube into an outer tube. The glass material and the fluorescent powder are placed between the outer and inner tubes and are formed into a wheel body. In another method, the glass material and the fluorescent powder are sintered at a temperature of 500-1000° C. to form at least one glass phosphor color block that is subsequently coupled to a substrate to form a glass phosphor color wheel.

Abstract: A projector using glass phosphor as a color mixing element includes: a laser light source capable of producing light; an optical system, the color mixing member, a reflection element and an imaging system disposed on a light transmission path. The optical system includes a color wheel, the light will be converted into light beams of different colors when passing through the color wheel. The color mixing element is located between the laser light source and the optical system and made of glass phosphor, and a glass transition temperature of the glass phosphor being higher than 500° C. The imaging system serves to convert the light beams into an image. The use of the heat-resistant glass phosphor as the color mixing element enables the projector to have a wide color gamut and an adjustable color gamut.

Abstract: Disclosed is an ultra-thin light guidance device, which is realized through integrating a micro prism set into a light guidance module, and achieving filtering the incident lights by means of a micro grating in said micro prism set, thus only part of the effective incident lights pass through said micro prism set, while the rest of incident lights are reflected back to a bottom light guidance layer and a bottom light reflection plate, so that lights are reflected back and enters into said micro prism set again. As such, in less than 10 mm thickness of the ultra-thin light guidance device, a dot or a line light source is converted to form an evenly distributed and highly efficient surface light source by making use of said micro prism set.
