    Abstract

    LED is widely used in different lighting environment instead of traditional lighting source as its power becoming higher and higher. LED lens are always needed to make rectangular spot to avoid waste of flux in some illumination design of indoor and road conditions. In this design, total internal reflection(TIR) lens and micro-lens array are integrated by Light Tools. The transmission and the total reflection surface of TIR lens are all set up to quadric for optimization. And the ratio of length and width of a single micro-lens is set to 1∶1, 3∶2 and 4∶3. The size of the micro-lens and spherical curvature are also variable for further optimization. Finally, a uniform rectangular spot appears on the detector, and the ratio of the length and width is the same as the ratio of micro-lens which can meet illumination design of different condition.
