Industrial Lighting System Design Standards for Thermal Power Plants

As core facilities for energy production, thermal power plants require lighting systems that directly impact equipment maintenance efficiency and personnel safety. This article provides an in-depth analysis of lighting requirements for critical areas in power plants, along with professional solutions compliant with international safety standards.

Core Design Principles for Thermal Power Plants Lighting Systems

1. Safety-First Design: All fixtures must meet explosion-proof certifications and include shock protection.
2. Environmental Adaptability: IP65/WF2 ratings to resist coal dust, moisture, and chemical corrosion.
3. Smart Energy Control: Integrated light sensors + timers for intelligent energy management.
4. Ergonomic Optimization: UGR<19 anti-glare technology to eliminate visual fatigue risks.
