基于遗传算法优化的线光源节能排列方式研究

摘要

The indoor lamps are performed with uniform and symmetrical arrangement according to the size of the space area,which can ensure the appearance of the space,but the lack of the scientific lighting arrangement mode and reasonable evaluation method may cause the unnecessary waste because of the excessive lamps quantity. The mathematical model was con-structed for the line light source. The evaluation function is constructed to make the illumination of each point on the working plane uniform and appropriate. The genetic algorithm is used to carry out the optimization layout for the line light source. The energy-saving evaluation index is introduced for the sample point. The Matlab is adopted to simulate the indoor line light source arrangement when the index is optimal,to build the energy-saving arrangement model of the line light source,and realize the efficient use of line light source.%目前室内灯管多以空间面积大小为基准进行均匀对称排列,这样虽保证了空间的美观程度,但因为缺少科学的采光排列方式和合理的节能评价方法,从而造成因灯管数量过多而引起不必要浪费.通过对线光源进行数学建模,构造使工作平面上各点照度均匀且适当的评价函数,采用遗传算法对线光源进行优化布局,并从样本点入手引入节能评价指标,运用Matlab仿真节能指标最优时的房间线光源排列方式构建线光源的节能排列模型,实现线光源的高效利用.
