‌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).
