Light pollution intrusion light due to overuse and misuse of lighting, Urban Skyglow, Glare, Clutter, and Overillumination affect the human body's physiological process, and excessive light mainly causes confusion in night activities. This study suggested a way to reduce light pollution by measuring the vertical illuminance, discomfort glare index(UGR), and glare index(TI) of the residential area for light pollution caused by the lighting environment of outdoor sports facilities adjacent to the residential area. The results of this study are as follows. First, as a result of the illumination simulation, it was confirmed that the reference value according to the KSC illumination standard was met, and the lighting environment of the sports facility has no problem in proceeding with the game. Second, the maximum illuminance value of the vertical plane measured in the window of the residential area barely satisfies the reference value of 10[lx] or less. As a result of implementing it as a way to reduce light pollution, the maximum illuminance value of the vertical plane was measured from 0.94 to 9.82[lx] before improvement to 0.72 to 6.62[lx], and the maximum illuminance of the vertical plane after improvement was reduced by more than 20%. Third, the UGR index of residential area (apartment housing) was satisfied with the international standard of 22, and also satisfied with the domestic Central Environmental Dispute Committee's acceptance limit of 36, so there was no difference between before and after the change. Fourth, as a result of evaluating the unpleasant glare measured in the 500M range of the up and down lines, it was measured as 4.6[%] of the up line and 3.1[%] of the down line, and there was no difference before and after the change as a result of satisfying the unpleasant glare acceptance limit(10%). It is meaningful to use it as light pollution prevention lighting installation data for outdoor sports facilities in the future by presenting supplementary points for the 'light radiation permission standard' of the 'light pollution prevention method of artificial lighting' according to the lighting environment of sports facilities.
