    In order to improve the light utilization rate of the existing outdoor basketball court lighting and reduce the glare value, this paper designs a deflected lighting scheme to reduce the light exposure to the outside of the field. Through optical analysis of different lighting schemes, the reasons for the low utilization rate of light are found, and the deflected light design is carried out to make the light illuminate the inside of the venue in a concentrated manner. DIALux is used for simulation analysis of the overall scheme: the overall illuminance uniformity reaches 0.85, and the measured glare value GR maximum is 29, which is far less than the outdoor stadium glare required value of 50. The uniformity and glare control can meet the needs of various competitions. The calculated light utilization rate of 75% is far greater than the 52% of the existing lighting scheme. Compared with the existing lighting scheme, the energy-saving effect is significant.
