In sports lighting, unstable light energy output from stadium lamps can cause flickering and stroboscopic effects, creating visual hazards for athletes.
1. Manifestation of Stroboscopic Effects
When the movement frequency of fast-moving objects (e.g., badminton, table tennis, basketball, volleyball) synchronizes with the flicker frequency of stadium lighting, stroboscopic effects occur. This phenomenon distorts players' perception of ball trajectories, causing:

1. Manifestation of Stroboscopic Effects
When the movement frequency of fast-moving objects (e.g., badminton, table tennis, basketball, volleyball) synchronizes with the flicker frequency of stadium lighting, stroboscopic effects occur. This phenomenon distorts players' perception of ball trajectories, causing:
Illusory speed variations (appearing slower/faster than actual)
Multiple ghost images ("re-shadowing"
Motion blur ("trailing effects"
These visual distortions lead to misjudgment of ball position and timing errors during play.
