  • Magnetic stirring mechanism
    Patent number: 8303165
    Abstract: The present invention provides a stirring mechanism with magnetic force. It has a central rotary arm with permanent magnet, as well as a plurality of lever arms, each having one respective permanent magnet. A track disk rotates synchronously with the central rotary arm. An elliptic track slot in the track disk traps the lever arms to swing forward and backward. The lever arms exhibit alternate motions of approaching and leaving, thereby causing a stirring effect.

  • Method of making pure white light source
    Patent number: 8071159
    Abstract: The present invention provides a method of making pure white light source. A phosphor powder which at least comprises three elements Zn, Se, and O is used for being excited by a purple-LED to emit pure red light (650 nm). The phosphor powder is coated on the purple-LED (Ex. chromaticity coordinate of x:0.26, y:0.10), and then placed aside a pure green-LED (or chip), when the purple-LED and the green-LED are electrified, a pure white light source with high color rendering index and high color saturation is obtained.
