Detailed Product Description



Custom Borosilicate Glass Aspheric LED Lens for Enhancing LED Efficiency

Material Composition
The lens is precision-engineered from borosilicate glass, a high-performance material known for its low thermal expansion, chemical durability, and optical clarity. Customized with an aspheric (non-spherical) surface design, it is manufactured using advanced molding or diamond-turning techniques to achieve ultra-precise curvature.

Key Properties

  1. Thermal Stability: Withstands extreme temperatures (-50°C to 450°C), preventing deformation under prolonged LED heat exposure.

  2. High Refractive Index: Optimizes light transmission (up to 99% in visible spectrum) and minimizes Fresnel losses.

  3. Low Dispersion: Reduces chromatic aberration, ensuring consistent color fidelity.

  4. Chemical Resistance: Resists corrosion from moisture, UV radiation, and harsh environments.

Functional Benefits

  • Enhanced Light Collimation: The aspheric shape eliminates spherical aberration, focusing LED light into a uniform, narrow beam with minimal scatter.

  • Improved Efficiency: Reduces energy loss by 15–20%, boosting lumen output and lowering power consumption.

  • Precision Beam Control: Custom curvature enables tailored beam angles (e.g., spotlights, floodlights) for targeted illumination.

  • Longevity: Maintains optical performance over time, unlike plastic lenses prone to yellowing.

Applications

  • Automotive Lighting: Headlights, fog lights, and interior LEDs requiring heat resistance and precise beam patterns.

  • Industrial Lighting: High-bay LEDs, UV curing systems, and machine vision where thermal stability is critical.

  • Architectural Lighting: Facade and accent lighting with customizable beam spreads.

  • Medical Devices: Surgical and diagnostic equipment needing distortion-free, high-intensity light.

  • Consumer Electronics: Projectors, flashlights, and smart home lighting.
