Abstract：Through in-depth analysis of related lighting design specifications, taking Chongqing Two-river Bridge for example, the article introduced how to properly set the calculating partition and presume reasonable computational grid based on the number of test points in the DIAlux simulation computation on the large-scale special-shaped component of oversize span bridges.And it put forward that instead of overall illumination uniformity on the lighted surface or vertical illumination uniformity, the illumination uniformity of the most disadvantaged horizontal line on the lighted surface should be paid attention to during the calculation, in order to ensure the quality of lighting.And the thesis indicated that the integrated use of power density value method, empirical method, software simulation method and field experiment, could significantly improve the efficiency of lighting design, and effectively reduce the error between measured data and design value.
