露天停车场夜间纠纷多：剐蹭找不到责任人，多数是因为监控画面里一片过曝或死黑——照明不均匀直接毁掉所有摄像头。
地面照度≥10lx且均匀度Uo≥0.4（CJJ45-2015停车场相关条款），监控点区域垂直照度≥20lx确保人脸与车牌可辨；高杆灯采用升降式设计方便检修。
我们按监控点位反推布灯方案，先测摄像头视场再定灯位，保证每个车位既是照明盲区的反面、也是取证清晰区。
Outdoor parking lots see frequent night disputes: scratches with no accountable party because CCTV footage is either blown out or pitch dark — uneven lighting ruins every camera.
Ground illuminance ≥10 lx with Uo≥0.4 (CJJ45-2015 parking clauses); vertical illuminance ≥20 lx at camera positions to make faces and plates identifiable; high-mast poles use raising-lowering design for easy servicing.
We reverse-engineer the layout from camera positions — surveying each CCTV field of view before placing poles, so every bay is both evenly lit and forensically usable.
