‌High-temperature Resistant Industrial LED Lighting Borosilicate Glass Led Lens 

1. Glass Material

   • Borosilicate Glass: Composed of silica (80–90%) and boron trioxide (10–15%), offering exceptional thermal shock resistance and chemical stability. Complies with ISO 3585 standards for industrial-grade performance.

2. Key Properties

   • High Thermal Resistance: Operates reliably in extreme temperatures (-30°C to +450°C), ideal for high-power industrial LEDs.

   • Low Thermal Expansion (3.3 × 10⁻⁶/K): Prevents warping or cracking under rapid temperature changes.

   • Optical Clarity: >92% visible light transmission (400–700 nm) with minimal UV degradation over time.

   • Chemical Durability: Resists acids, alkalis, and moisture, suitable for harsh industrial environments.

   • Scratch Resistance: Harder than plastic alternatives (e.g., polycarbonate), ensuring long-term durability.

3. Primary Functions

   • Beam Shaping: Focuses or diffuses light for uniform illumination in spotlights, floodlights, or task lighting.

   • Heat Dissipation: Manages thermal load from high-wattage LEDs, preventing overheating and lumen depreciation.

   • Environmental Protection: Seals LED modules against dust, humidity, and corrosive fumes in factories or outdoor settings.

4. Applications

   • Industrial Facilities: High-bay lighting, assembly line task lights, and hazardous area (ATEX) fixtures.

   • Outdoor Lighting: Streetlights, parking lot luminaires, and port/airport runway lights.

   • UV-C Systems: Germicidal lamps for water treatment or sterilization, leveraging borosilicate’s UV transparency.

   • Mining & Oil/Gas: Explosion-proof lighting in volatile environments.

   • Warehouse & Cold Storage: Freezer-compatible lighting with thermal cycling resistance.

5. Advantages Over Plastic Lenses

   • Longer Lifespan: Withstands high heat and UV exposure without yellowing or brittleness.

   • Fire Resistance: Non-flammable (melting point >800°C), critical for safety in industrial zones.

   • Custom Optics: Moldable into convex, concave, or Fresnel designs for precise light distribution.

6. Technical Specifications

   • Refractive Index: 1.47–1.51 (optimized for beam control).

   • Surface Quality: 60-40 scratch-dig standard; λ/4 flatness for precision optics.

   • Dimensions: Custom diameters (10–300 mm), thickness (2–20 mm).
