High Precision Aspheric Borosilicate Glass Diffuser Lens for Downlight Fixture
This high-precision aspheric lens is engineered as a critical optical component for modern downlight fixtures. Manufactured from superior borosilicate glass and designed with an advanced aspherical geometry, it delivers unparalleled light control, efficiency, and durability for professional lighting applications.
1. Material & Construction
Core Material: Made from premium Borosilicate Glass, renowned for its exceptional properties. This material ensures high thermal resistance and long-term structural stability.
Manufacturing Process: Utilizing advanced molding techniques, this lens achieves a complex aspheric design with ultra-precise surface contours, guaranteeing consistency and optical accuracy in high-volume production.
2. Key Properties & Characteristics
High Thermal Stability: Borosilicate glass offers a low coefficient of thermal expansion, making the lens highly resistant to thermal shock and capable of withstanding intense heat from high-power LEDs without degrading or cracking.
Optical Precision: The aspheric design eliminates spherical aberration, a common optical distortion. This results in sharper focus, reduced light spill, and more efficient light transmission compared to simple spherical lenses.
Durability & Clarity: The material is inherently scratch-resistant and maintains its high light transmission and surface quality over a long lifespan, even in demanding environments. It is also resistant to chemical corrosion and yellowing from UV exposure.
3. Primary Function & Optical Performance
The core function of this lens is to precisely control and diffuse
light emitted from an LED source. It efficiently shapes the light
beam, creating a uniform, soft, and glare-free illumination. By
providing precise beam control, it minimizes light loss and ensures
the intended light pattern is projected onto the target area,
enhancing the visual comfort and effectiveness of the lighting
system.
4. Application & Uses
This lens is specifically designed for integration into downlight
fixtures across various settings, including:
Commercial Lighting: Recessed downlights in offices, retail stores, museums, and galleries where accurate color rendering and controlled illumination are crucial.
Architectural & Residential Lighting: High-end residential projects, hotels, and corridors that require precise, comfortable, and aesthetically pleasing light distribution.
Industrial & Task Lighting: Environments where reliable, consistent, and high-quality light is necessary for productivity and safety.
