综合管廊是城市地下生命线，舱内有电力电缆与燃气舱并存的高风险环境，照明灯具的一丝电火花都可能酿成大祸。
燃气舱灯具执行防爆标准Ex d IIB T4以上，电力舱IP65；人行通道一般照明30lx、逃生通道应急照明≥5lx持续60分钟；全部灯具接入管廊统一监控平台做在线状态监测。
我们的管廊灯具自带地址编码与电流回传，运维人员在控制中心就能看到每一盏灯的健康度，巡检人员下廊次数减半。
Utility tunnels are a city's underground lifeline where power cables share corridors with gas compartments — a single spark from a luminaire can escalate into disaster.
Gas compartments require Ex d IIB T4 explosion-proof luminaires, power compartments IP65; walkways 30 lx general, escape routes ≥5 lx for 60 minutes emergency; all lamps integrate into the tunnel SCADA for online health monitoring.
Our tunnel luminaires carry address codes with current telemetry, letting operators monitor each lamp's health from the control centre — halving physical inspection trips.
