保龄球道是超长视距场景：从助走到球瓶18米以上，照度沿球道渐变处理不好，玩家在出手瞬间反而看不清球瓶。
助走区200lx、球道中段150lx、瓶区局部300lx形成视线引导；球道上方灯具避开玩家正面视线，瓶区照明与显示屏亮度做匹配避免过曝。
我们的球道照明渐变曲线经职业球员实测调整，出手视野清晰度获得球馆老板与常客双重好评。
Bowling is an ultra-long sightline scene: 18+ metres from approach to pins — without a proper gradient along the lane, players cannot see the pins at the moment of release.
Approach 200 lx, mid-lane 150 lx, pin deck locally 300 lx as a sightline gradient; overhead luminaires avoid players' frontal view; pin-deck brightness matched to scoring screens to prevent washout.
Our lane gradient curve was field-tuned by professional bowlers — release-phase visibility praised by both owners and regulars.
