作为新一代照明光源lEd照明技术已经有了长足的发展,但单颗lEd并不能满足正常的照明需求,想达到所要的照明效果通常采用多个lEd组合。lEd组合有各种形式,利用TrACEPrO对4种lEd平面阵列形式,即:3x3方形阵列、3-6同心圆阵列、阿基米德螺线阵列以及1-8圆形阵列进行了详细的光学分析。在满足照明要求的条件下,通过对比找到一种最优化的设计,发现1-8圆形阵列效果最好,所占面积最小,从而可以减少材料的浪费,进一步提高lEd照明的性价比,为lEd照明的普及提供设计上的借鉴。The lighting technique of LED has experienced substantial progress.However,a single LED cannot meet the demand for the normal lighting.LED combination is usually adopted to achieve the desired lighting effects.The forms of LED combination are varied.A detailed optical analysis on four forms of LED planar array is taken by using Tracepro,which are 3×3 square array,3-6 concentric array,Archimedean spiral array and 1-8 circular array.By the comparison,which find that 1-8 circular array is the best optimal design to reduce the waste of material and further improve the cost performance of LED lighting under the conditions of meeting the lighting requirements.A ref erence can be provided for the popularity of LED lighting.福建省重大科技项目(2006H0092
