Abstract

In light-emitting diode (LED) street lamp design, it has always been an obsession that how to achieve an expected illumination distribution confined to a given region. To solve this problem, a new optimization strategy is proposed. In view of the practicability of actual production, we select the relatively mature approach that is based on both the Snell law and the energy conservation law which would obtain coordinate relations between the spaces the light source and target plane owned respectively and a set of equations to establish the initial construction of free-form lens. In addition, all the processes of simulation, analysis and optimization as well are accomplished in software. Generally speaking, for construction method which is in the light of the set of equations, the major improvement ideology focus on finding out the most suitable mapping relationship between the two coordinate systems. So does our work. In order to get better performance, the grid of control points must be modified. Then the core problem lies in determining the direction and distance of every point’s movement contained in the grid. The rule of changing direction has a bearing on energy relations while migration length is gained by direct search algorithm.We apply the method in uniform illumination and get some effect. In short, the optimization strategy provides a practical and simple way for street lamp design of LED illumination.
