| 摘 要： | 由于LED发射光强的逐渐提高，许多照明系统使用单颗LED作为光源就可以满足不同场合的需求。通过对LED的发光特性的分析，提出了一种以单颗LED作为光源的均匀照明透镜的设计。首先由Snell定律和能量守恒定律构建出满足设计条件的透镜的数学方程，运用MATLAB进行编程解出该方程，再使用Pro/E对求解出的坐标点进行拟合来得到透镜模型，最后用TracePro将得到的透镜模型进行光线追击，通过得到的照度图可知最终达到在规定区域内均匀照明的需求。

| Abstract: | With the increasing of emission intensity of LED, illumination system with a single LED light source can meet requirements in many fields. According to the characteristics of LED source, a method of lens design of LED uniform illumination was proposed. At first,a lens design equation by Snell's law and the law of conservation of ener-gy was formulated;and the result of the equation was solved by MATLAB. Then the profile curves were acquired by curve fitting of the coordinate spots with software Pro/E;so the lens model could be got. At last,the lens model was introduced into TracePro and rays were traced. Finally the uniform illumination at target area was obtained. |
