Design of the laboratory illumination and practical measurement by integrating optimization of power usage

In this paper, the research is mainly focused on the optimization of average intensity of illumination and power usage the author studied previously to make comparisons via simulation and actual measurement [1]. In proposed method, the concept of average intensity of illumination is utilized. Then, a set of calculation formula for lighting is derived and the optimization model is used to determine the suitable number of lamps by taking the saving of electric energy into account. The limitations for optimization include the intensity of illumination needs to meet the standards, average intensity of illumination, requirements for distances between lamps, etc. Besides, to simplify the tasks for data input and representation of analysis results, a users´ interface implemented with MATLAB and GUIDE is developed for the optimization of average intensity of illumination and power usage. In such way, users could obtain the optimization results in a short time, and easily verify the performance of energy saving and related requirements of illumination design. In this study, the laboratory of electrical machine at the department of electrical engineering in Chienkuo Technology University is used as a simulation and test field. From the actual measured results, the performance of proposed optimization procedure for the design of illumination can be verified, which proves that the total power usage for the design of illumination in the same area would be lower than that designed with the general method.
