Durable High-Performance LED High Bay Light Lens - Polished Borosilicate Glass
1. Material Construction
Core Material: Optical-grade borosilicate glass (Schott Borofloat®/equivalent)
Surface Treatment: Precision optical polishing (Ra < 0.5nm surface roughness)
Structural Enhancement: Chemically tempered for subsurface compression
2. Critical Properties
Extreme Durability: IK10 impact rating (20J impact resistance) against falling tools/debris
Thermal Resilience: Withstands ΔT >220°C (rapid cooling from 300°C→80°C)
Optical Excellence: >94% visible light transmission (380-780nm) with <1% haze
Chemical Resistance: Immune to alkaline cleaners, oils, and warehouse fumes
UV Stability: Near-zero solarization after 50,000+ hours of 100W LED exposure
Thermal Management: Withstands 150°C continuous operating temperatures
3. Core Functions
Precision Beam Control: Engineered optics achieve 60°-120° batwing distribution eliminating ceiling shadows
Lumen Maximization: <6% optical loss vs. polycarbonate (boosts usable lumens by 15-20%)
Hazard Mitigation: Shatterproof design (EN 12150-1 compliant) contains fragments upon impact
Environmental Sealing: Compatible with IP65/66 housings resisting dust/water ingress
Maintenance Reduction: Non-yellowing surface avoids frequent cleaning/replacement
4. Industrial Applications
Warehouse Lighting: 30-50ft ceiling high bays in distribution centers
Manufacturing Facilities: Assembly line lighting with vibration resistance (ISO 2372 compliant)
Cold Storage: Freezer-rated lenses (-40°C to +150°C operational range)
Gymnasiums/Sports Arenas: High-impact protection from balls/equipment
Aircraft Hangars: Fuel-fume resistant lighting solutions
