Custom Optical Design Borosilicate Glass Lens for High-Efficiency LED Street Lamp & Flood Light

1. Core Material & Key Feature:

• Primary Material: Engineered Borosilicate Glass (e.g., Borofloat, equivalent to Pyrex).

• Key Feature: Custom Optical Design - The lens profile (e.g., freeform, TIR, multi-faceted) is uniquely calculated and manufactured to achieve a specific, efficient light distribution pattern tailored to the LED source and fixture.

2. Defining Physical & Optical Properties:

• High Thermal & Shock Resistance: Borosilicate glass has a very low coefficient of thermal expansion, making it high temperature resistant and able to withstand thermal cycling from the LED and outdoor weather without cracking or degrading.

• Superior Durability & Weatherability: Highly resistant to UV radiation, water, chemicals, and abrasion, ensuring long-term optical performance and clarity in harsh outdoor environments.

• Precision Optical Performance: The custom-molded or ground surfaces provide precise beam control, high transmission (>92%), and minimal light loss through superior light extraction and redirection.

• Mechanical Stability: Maintains its shape and optical integrity under vibration and physical stress.

3. Primary Function in a Lighting System:

• Efficiency & Photometric Control: The core function is to maximize luminaire efficacy by capturing and precisely redirecting LED chip output into a required beam pattern (e.g., Type II-V road distribution, asymmetrical flood) with minimal spill light and glare.

• Secondary Optics: Acts as the key secondary optic, transforming the raw LED emission into a useful, application-specific illumination pattern that meets regulatory standards (e.g., Dark Sky, roadway luminance).

• Protective Enclosure: Seals and protects the internal LED module from environmental factors (dust, moisture) while allowing optimal heat dissipation.

4. Target Applications & Industries:

• Public & Roadway Lighting: LED Street Lamps, roadway luminaires, highway lights, and tunnel lights.

• Area & Flood Lighting: High-efficiency LED Flood Lights for parking lots, stadiums, building facades, security areas, and industrial yards.

• Architectural & Landscape Lighting: High-power outdoor fixtures requiring specific beam shaping and durability.

• LED Luminaire Manufacturing: A critical custom component for OEMs designing high-performance, specification-grade lighting products.
