    • A light emitting device comprises at least one solid-state light source (LED) operable to generate excitation light and a wavelength conversion component located remotely to the at least one source and operable to convert at least a portion of the excitation light to light of a different wavelength. The wavelength conversion component comprises a light transmissive substrate having a wavelength conversion layer comprising particles of at least one photoluminescence material and a light diffusing layer comprising particles of a light diffractive material. This approach of using the light diffusing layer in combination with the wavelength conversion layer solves the problem of variations or non-uniformities in the color of emitted light with emission angle. In addition, the color appearance of the lighting apparatus in its OFF state can be improved by implementing the light diffusing layer in combination with the wavelength conversion layer. Moreover, significant reductions can be achieved in the amount phosphor materials required to implement phosphor-based LED devices.

    • A method to predict heat transfer coefficients for metal castings during quenching and/or cooling is provided. First, an initial set of HTC data are obtained from the computational fluid dynamics (CFD) simulation based on the metal casting geometry, initial metal casting temperature (distribution), quench bed/tunnel dimensions and set-up, and a given or baseline (standard) quenching condition including, but not limited to, air and/or gas flow velocity, air and/or gas flow direction relative to the work piece, air and/or gas temperature, air and/or gas humidity, etc. The initial HTC values for the entire surface of the work piece calculated from CFD can then be optimized by multiplying scale factors to minimize the error between the predicted temperature-time profiles and the experimental measurements for the given or standard/baseline quench condition. When the HTC values are optimized for a standard/baseline quench condition, a set of semi-empirical equations (or weight functions) can be used to quickly modify the standard/baseline HTC data for different quenching conditions (i.e., variations of quenching conditions from the baseline) without performing complete heat transferring and optimization calculations. A system and article of manufacture are also provided.
