Custom Shatterproof High Transmission Borosilicate Glass LED Spotlight Lens

‌Custom Shatterproof High Transmission Borosilicate Glass LED Spotlight Lens

1. Material:

• Borosilicate Glass (Schott Borofloat® or equivalent): Chemically strengthened/tempered variant with ultra-low thermal expansion (CTE: 3.3 × 10⁻⁶/K).

• Custom Geometry: Precision-molded or CNC-machined to specific diameters (20-300mm), thicknesses (2-15mm), and optical profiles (aspheric, plano-convex).

2. Key Properties:

• Shatterproof Design: Thermally tempered or chemically strengthened to achieve 5x higher impact resistance vs. annealed glass (withstands 0.5kg steel ball drops from 1m+).

• High Light Transmission: >93% visible light transmission (380-780nm) with anti-reflective coating options (>97%).

• Thermal Stability: Handles ΔT >150°C without cracking – critical for high-power LED spotlights (50-500W).

• Optical Precision: Wavefront distortion < λ/4 and surface roughness < 5nm for distortion-free beam projection.

• UV/IR Resistance: Near-zero solarization (yellowing) under prolonged UV/IR exposure from LEDs.

3. Primary Functions:

• Beam Control & Collimation: Precisely focuses LED output into tight beam angles (10°-45°) with minimal scatter loss.

• Hazard Mitigation: Shatterproof construction contains glass fragments upon impact (EN 12150-1 compliant).

• Efficiency Maximization: >93% transmission ensures maximum lumen output per watt, reducing energy costs.

• Environmental Protection: Seals against IP65/66-rated dust/water ingress while resisting corrosion.

4. Customization Options:

• Optical Profiles: Aspheric, Fresnel, convex-concave designs for beam shaping.

• Coatings: AR, hydrophobic, or color-correction layers.

• Peripheral Features: Flanges, mounting threads, or edge treatments for fixture integration.

• Compliance: Custom certifications (UL, CE, RoHS) upon request.

5. Applications:

• Architectural Spotlights: Museum/gallery accent lighting, façade illumination.

• Stage & Entertainment: Follow spots, moving head fixtures, concert stage lighting.

• Industrial Lighting: High-bay factory spotlights, inspection lamps.

• Retail Lighting: Display case highlighting, premium product showcasing.

• Marine/Aviation: Vibration-resistant navigation or deck lighting.
