项目背景与挑战

The mine's underground work faces and surface preparation plant relied on legacy fixtures with no remote dimming or status monitoring. The underground environment imposes strict explosion-proof, power-consumption, heat-dissipation, and wide-temperature requirements that standard smart control modules cannot meet for ExdI certification.

解决方案

Deployed 1,200 AMALAX LoRa single-lamp controllers, including 600 ExdI mining explosion-proof certified units for underground work faces and haulage roadways. Each controller draws <0.5W in standby and operates continuously across -20°C to 60°C. 3 concentrators relay data via LoRa to the cloud lighting platform, with independent dimming schedules per zone — unmanned areas auto-dim to 30% at night.

实施效果

  • All 600 underground explosion-proof fixtures certified to the ExdI mining standard
  • Single-lamp controller standby power <0.5W, continuous operation across -20°C to 60°C
  • Energy savings 42% — annual electricity cost reduced by ~¥380,000
  • Average fault response time: 48 hours → 12 minutes

Customer Feedback

"AMALAX's explosion-proof lighting controllers run reliably in the high-humidity, dusty underground environment. The dimming schedules cut our electricity bill significantly, and inspections are much easier now."
