Durable Optical Aspheric Led Lens for Outdoor LED Fixtures

1. Material

• Core Substrate:

  • Optical-Grade : High impact resistance, UV-stabilized.

  • Borosilicate Glass (e.g., B270): Extreme scratch/chemical resistance (premium option).

• Additives: UV inhibitors, anti-yellowing agents, and diffusion particles (optional).

2. Key Properties

• Environmental Durability:

  • UV Resistance: Withstands prolonged sunlight (5–10+ years without yellowing).

  • Thermal Stability: Operating range: –40°C to +120°C (prevents warping/cracking).

  • IK Rating: IK08+ impact resistance (20-joule shock protection).

  • IP68 Sealing Compatibility: Resists dust/moisture ingress.

• Optical Performance:

  • Aspheric Design: Eliminates spherical aberration for sharp beam edges.

  • Beam Angle Control: Precision collimation (e.g., 10°–60°).

  • Transmission: >92% (PMMA/Glass), >89% (UV-stabilized PC).

3. Primary Function

• Beam Shaping: Converts raw LED emission into uniform, glare-free illumination with controlled cutoff.

• Efficiency Optimization: Maximizes lux/watt by reducing light spillage.

• Environmental Protection: Shields LEDs from rain, debris, and thermal stress.

4. Critical Applications

• Street Lighting:

  • Roadway luminaires (meets Dark Sky standards).

  • Tunnel/parking lot fixtures.

• Architectural Lighting:

  • Facade washers, landscape uplights.

  • Bollard/pathway lights.

• Industrial/Commercial:

  • High-bay warehouse fixtures.

  • Stadium/arena floodlights.

• Transportation:

  • Airport runway lights.

  • Marine/offshore navigation fixtures.
