GLASS PHOSPHOR COLOR WHEEL AND METHODS FOR PRODUCING THE SAME

摘要

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.
