足球场灯光最怕'频闪错觉'：劣质驱动让高速飞行的球在视网膜上出现多重残影，前锋射门时看到三个球。
训练200lx、业余比赛500lx、专业赛事按转播等级（JGJ153-2016）；灯具波动深度须低于6%（低频闪认证），四塔或六塔布灯覆盖全场且边线垂直照度均匀。
我们的球场灯全部搭载DC恒流驱动彻底消除频闪，并出俱照度与眩光双检测报告，供参赛队赛前查验。
Football fields dread stroboscopic illusion: cheap drivers make a fast ball leave multiple retinal after-images, and strikers see three balls at once.
Training 200 lx, amateur 500 lx, professional per broadcast class (JGJ153-2016); luminaire flicker depth under 6% (low-flicker certified); four- or six-tower layouts covering full pitch with uniform sideline verticals.
Every pitch luminaire runs DC constant-current drivers that eliminate flicker outright; illuminance and glare test reports ship with each venue for pre-match inspection.
