在太阳能发电中，电池板受光面与太阳光线的角度是决定太阳能发电效率的关键因素。

Based on the prior art, the optical engine according to the invention has the improvements that, three optical axis steering components are respectively introduced into red, green and blue light illumination systems, and an optical axis lengthening structure is introduced into the green light illumination system, so that optical axes of the red, green and blue light illumination systems, each of which is from an LED resource to the optical axis steering component, are counterclockwise rotated for 90 degrees, parallel with each other, parallel with an optical axis of a projection lens, arranged in a same plane and positioned under the projection lens, luminous faces of three LED luminous chips of the red, green and blue light illumination systems are in a same plane, and the three LED luminous chips can be mounted on a same heat-radiating plate, therefore, the heat-radiating system has a simplified structure, and the optical engine has reduced size.

在背景技术所述的光学引擎的基础上作以下改进，在红、绿、蓝光照明系统中引入三个光轴转向器件和在绿光照明系统中引入光路加长结构，旨使：红、绿、蓝光照明系统各自的从LED光源至光轴转向器件部分的光轴朝逆时针方向转动90°、互相平行、与投影镜头的光轴平行、居同一平面和位于投影镜头的下方，红、绿、蓝光照明系统的三个LED发光芯片的发光面居同一平面，三个LED发光芯片可安装在同一块散热平板上，散热系统的结构简化，所述的光学引擎的尺寸减小。

In the paper, on the basis of aggregation of previous studies, the development of optical technology and development trends at home and abroad are introduced, the principle of Fresnel lens is summarized. In accordance with its principle, circle equidistant steps Fresnel lens design is described. And on this basis, based on Fresnel design, also based on a continuous upward spiral of the plane curve concept, incidence surface and the backlight is set up to greet Archimedes - Fresnel lens design formula and the Second parabolic type Fresnel lens design formula, and on this basis, the advantages and disadvantages of the three designs is discussed.

本文在充分了解非球面光学技术在国内外的发展状况和趋势的基础上，同时从菲涅尔透镜的光学原理出发，并根据它的工作原理推导了圆环等距菲涅尔透镜的设计步骤，并在此基础上依据菲涅尔的设计思想，同时依据平面曲线的连续又呈螺旋的构思，推导出了迎光面和背光面阿基米德型菲涅尔透镜的设计公式和二次抛物面型菲涅尔透镜的设计公式，并在此基础上讨论了这三种设计各自的优缺点。
