Abstract: A phosphor deposition process and apparatus that enables an efficient, consistent, and flexible white light LED light engine by spraying a conformal coating of phosphor matrix onto an array of LEDs to achieve high color uniformity, consistency, and efficiency. A predetermined ratio of one or more phosphor powders are mixed with a support matrix (preferably silicone), the types and amounts of which are calculated to provide a predetermined spectral output. A low-viscosity carrier is introduced into the phosphor matrix to allow for further processing and deposition. The phosphor matrix and carrier mixture is atomized and sprayed in one or more uniform layers onto one or more LED devices. Computerized control, movable stages, and in-process spectral monitoring are incorporated to provide rapid and accurate processing of LED devices.

Abstract: The present invention relates to a combustion temperature sensor, and, more particularly, to a combustion temperature sensor that measures infrared radiation emitted at several preselected wavelengths from a flame and/or a flame's hot gas at a turbine inlet location and applies the energy signals. to a calculation model to yield temperature.
