Automotive Parts Manufacturing Workshop Lighting and UV Disinfection Retrofit Project
Client Background:
A tier-1 automotive supplier's precision machining workshop with 5,000㎡ production area, operating 24/7 with high requirements for visual accuracy and environmental cleanliness.
Solution Deployed:
Integrated 150W UVC+White LED high-bay fixtures (300 units) with DMX-controlled zoning system. Each fixture combines 6000K 140W white LEDs (Ra92) with 10W 275nm UVC modules, achieving 200 lux uniform illumination with 50μW/cm² UVC irradiance at 3-meter height.
Technical Implementation:
• Staggered mounting pattern (every 6 meters) with 8-meter mounting height
• UVC automatic activation during shift changes (30-min cycles)
• Real-time irradiance monitoring via IoT sensors
• Emergency override with occupancy detection
Performance Metrics (after 6 months):
• Surface bacterial count reduction: 98.7% (from 120 CFU/100cm² to 1.5 CFU/100cm²)
• Airborne particle reduction: 94.2% (PM2.5 maintained below 15μg/m³)
• Energy savings: 43% vs previous metal halide + separate UV system
• Defect rate reduction: 31% attributed to improved visual conditions
• LED maintenance: 0 failures, UVC output degradation <3%
Client Feedback:
"The system eliminated weekend chemical fumigation, saving €18,000 annually in disinfectants alone. Production continuity improved as disinfection no longer requires line stoppages."
