High frequency electrodeless lamp(Hereinafter referred to as electrodeless lamp),as a new light source,attracts more and more widespread attention with its energy saving,long life and other significant advantages.Electrodeless lamp has two main direction of research,which is the design of the power circuit and the design of foam body.The research and development in terms of power circuit are very quickly.However,the design and research development of the body in the electrodeless lamp are slow,still in the stage of exploration and experiment.An important goal of development and design of electrodeless lamp is how to improve photosynthetic efficiency performance of foam body.Therefore,establishing photosynthetic efficiency prediction model of the electrodeless lamp body is of great significance for improving the quality of electrodeless lamp body production.It can guide design and production of the cylindrical electrodeless lamp body parameters.Based on the cylindrical electrodeless lamp as the research object in the thesis,the electrodeless lamp work principle and luminescence mechanism of foam body internal have been analyzed.Establishing photosynthetic efficiency prediction model of the electrodeless lamp body by COMSOL Multiphysics more physical field simulation software and support vector machine(SVM)method,and getting the optimal parameters of the cylindrical electrodeless lamp in nominal power by genetic algorithm to optimize.Considering the actual production needs,simulation platform of the cylindrical electrodeless lamp is built.This thesis provides a new way of thinking about the design and development of the cylindrical electrodeless lamp and my specific work as follows:First,for the problem that it is difficult to measure and reappear the dates of electrodeless lamp in vivo response,this thesis establishes a lighting efficiency prediction model of plasma reactor in electrodeless lamp bulb across adding the bulb geometry and physical processes reactions to the COMSOL simulation platform.Second,the data of the parameter that can decide lighting efficiency of the plasma reaction process—the density of Hg atom in 63P1 condition is obtained by the calculation of sectional data.Lighting efficiency prediction model of electrodeless lamp in plasma reactor is established by support vector machine(SVM).And the model is optimized by means of genetic algorithm.Solving the optimal parameters of the pressure inside the bulb,the output frequency of the coupler,the radius of the body and the height of the body in nominal power are obtained on the optimal lighting efficiency conditions.The results provide a basis for the improvement of lamp production and product quality.At last,based on lighting efficiency prediction model of the cylindrical electrodeless lamp and the parameter optimization in nominal power of electrodeless lamp in as the research object in the thesis,considering the actual production needs,simple simulation platform of the cylindrical electrodeless lamp is built by the integration of data resources.The simulation platform can be used for lighting efficiency prediction of the cylindrical electrodeless lamp and the parameter optimization in nominal power of electrodeless lamp,which is convenient for experiment operation and simple and clear for operation steps to achieve a friendly man-machine interface,exploring to build and design simulation platform of the cylindrical electrodeless lamp preliminarily.
