| Popis: | 103 This research uses the properties of LED light sources to build a numerical model of the thermal power density for remote-dome phosphor package. Monte Carlo method is applied to solve the thermal power density for the other phosphor packaging method. Finite element analysis software is used after to simulate the temperature distribution of LEDs to analyze with scanning the parameters of electric power, power efficiency, and quantum efficiency of phosphor and the thermal conductivity of the adhesive used. Furthermore, the geometrical structure of the phosphor packaging is change. The packaging methods are based on remote-dome, circular plate, half-dome and conformal coating. How the temperature distribution in LEDs will affected by electric properties, packaging material and geometrical structure are discussed in this research as well. |
