Durable High Precision Optical Glass Led Lens for Street Light
Material
The lens is manufactured from borosilicate glass or other specialized optical glass formulations. This is a significant upgrade from common polycarbonate or PMMA plastic lenses, offering inherent advantages in clarity and durability. The material is selected for its high homogeneity and excellent light transmission properties.
Key Properties
-
High Precision: The lens features a computer-optimized, often aspherical design, manufactured to micron-level tolerances. This ensures accurate light beam shaping with minimal scatter.
-
Exceptional Durability: The primary property is its high resistance to environmental degradation. It is highly scratch-resistant, UV-resistant, and does not yellow or haze over time.
-
Thermal & Chemical Stability: It withstands extreme temperature fluctuations and is resistant to moisture, salt spray, and pollution, ensuring consistent performance in harsh outdoor conditions.
-
High Optical Clarity: With a high Abbe number, it minimizes chromatic aberration, providing a clear, sharp cut-off and true color rendering.
Primary Function
The core function of this lens is to precisely control and distribute light emitted from high-power LED chips. It efficiently collects and redirects the luminous flux into a specific beam pattern, such as a Type II, III, or IV distribution for roadways. This maximizes luminous efficacy, reduces light pollution by preventing glare and spill light (providing a sharp cut-off), and ensures uniform illumination on the target surface.
Applications
This component is specifically designed for commercial and municipal street lighting and other demanding outdoor lighting applications, including:
-
Highway and Roadway Lighting
-
Tunnel Lighting
-
Public Area Lighting (parks, parking lots, pathways)
-
High-Mast Lighting for industrial areas and ports
-
Any application requiring long-term, maintenance-free, and efficient light distribution.
In summary, this optical glass lens represents the premium choice for sustainable and effective public infrastructure lighting, where performance, durability, and energy savings are paramount.
