Durable Led Street Light Lens Cover From Polished Borosilicate Glass
1. Material & Manufacturing
Core Material: Optical-grade borosilicate glass (Schott Borofloat® equivalent)
Surface Treatment:
Precision optical polishing (Ra < 0.5nm)
Optional anti-reflective coating (>98% transmission)
Structural Enhancement: Chemical tempering for subsurface compression
2. Critical Properties
Extreme Durability:
IK10 impact rating (20J impact resistance)
9H hardness (Mohs scale) against abrasion
Environmental Resistance:
Thermal shock tolerance: ΔT >220°C
IP68 waterproof rating (submersion to 1.5m)
Optical Performance:
>93% light transmission (uncoated)
<2% haze for uniform distribution
UV Stability: Near-zero solarization after 100,000+ operational hours
3. Core Functions
Optical Control: Engineered for Type II-V light distribution (batwing pattern)
Vandalism Protection: Withstands hammer blows and projectile impacts
Glare Reduction: Minimizes uplight (ULP <1%) for roadway compliance
Thermal Management: Allows passive cooling of 200W+ LED arrays
Maintenance Reduction: Eliminates yellowing/hazing vs. polycarbonate
4. Applications
Roadway Lighting:
Cobra head street lights (ANSI C136.31 compliant)
Highway/parking lot fixtures
Specialized Installations:
Coastal areas (salt corrosion resistance)
Desert environments (sand abrasion protection)
High-Security Zones:
Prison perimeter lighting
Military base illumination
