High-Precision Silicone Micro Lenses for LED | YEJIA LSR Optical Solutions

Silicone micro lenses for LED are precision-engineered optical components made from high-transparency liquid silicone rubber (LSR). They are designed to control, shape, and enhance the light emitted from LED chips, significantly improving optical efficiency, beam uniformity, and overall lighting performance.

These micro-scale lenses are widely used in Mini LED, Micro LED, Outdoor Lighting, and high-power LED applications, where precise light management is critical.

Advantages of Mini Secondary Silicone Lenses

Ultra-Precise Light Control

Silicone micro lenses are engineered with advanced optical geometries—such as aspherical, freeform, and TIR (Total Internal Reflection) designs—to precisely control beam angles and light distribution patterns.

High Light Transmission

With optical-grade silicone materials, these lenses achieve over 94% light transmittance, minimizing optical loss and maximizing LED brightness.

Enhanced Light Extraction Efficiency

Micro lens structures help reduce internal reflection within the LED chip, increasing light extraction efficiency (LEE) by up to 10–30%, depending on the design.

Excellent Thermal Stability

Silicone lenses can withstand continuous temperatures above 150°C, making them ideal for high-power and compact LED systems without deformation or performance degradation.

Superior UV Resistance & Anti-Yellowing

Unlike traditional plastic lenses (PMMA/PC), silicone materials offer long-term UV stability, preventing yellowing and ensuring consistent optical performance over time.

Flexible & Durable Material

Silicone’s inherent elasticity provides excellent resistance to cracking, mechanical stress, and thermal expansion mismatch.
