Abstract：In contrast to traditional metal halide surgical luminaries , the LED surgical luminaries have unmatched advantages.The variation of the lighting diameter is the important mark for surgical luminaries . But the optical analysis of variable lighting spot became difficult due to this .A modified Gaussian function was used in this paper to construct the illuminance distribution of single module light spot and total light spot.The variation rule of the illuminance distribution following the change of the shape and the shift amount of single light spot can be found within the range specified by the industrial standard .The important parameters in the overall optical design can be determined , and the requirement for the LED lens design is provided.
