Precision-Molded Borosilicate Glass Lens for High-Power Luminaires
Material
The lens is manufactured from borosilicate glass, shaped using a specialized high-temperature molding process. This technique allows for the creation of complex, repeatable optical geometries—such as TIR (Total Internal Reflection) collimators or aspherical shapes—directly from the raw glass material, ensuring inherent stability and purity.
Key Properties
-
Superior Thermal Endurance: It possesses exceptional resistance to thermal shock and can operate continuously under the high junction temperatures generated by powerful LED chips without degrading, yellowing, or cracking.
-
High Optical Precision & Stability: The precision molding yields optically perfect surfaces with excellent transmission and minimal flare. It maintains its clarity and focal length over time, unlike plastics that can warp or haze under heat and UV exposure.
-
Exceptional Environmental Resistance: The lens is highly scratch-resistant, chemically inert, and impervious to UV radiation, moisture, and pollution, guaranteeing consistent performance in harsh indoor and outdoor environments.
-
Mechanical Rigidity: It provides a structurally solid and durable barrier, protecting sensitive LED components from physical impact and environmental contaminants.
Primary Function
The core function of this lens is to efficiently manage and control the intense luminous flux from high-power LED sources. It is designed for precise beam shaping, collimating light into controlled, focused distributions (e.g., narrow spot, medium flood) with high efficiency and minimal optical loss, while also acting as the primary protective seal for the luminaire.
Applications
This component is critical in high-output commercial, industrial, and architectural lighting applications, including:
-
High-Bay and Low-Bay Industrial Lighting
-
Sports Stadium and Arena Floodlights
-
Architectural Facade and Area Lighting
-
High-Mast Roadway and Tunnel Lighting
-
Specialized Luminaires for photography, film, and scientific instrumentation.
In summary, this precision-molded borosilicate glass lens is the optimal solution for lighting manufacturers requiring uncompromising optical control, long-term reliability, and sustained performance from their high-power luminaire designs.
