20mm LED Lens TIR Optics

Single Asymmetric 25 Degree Beam Angle 20mm LED Lens TIR Optics for Indoor Area Lighting

Yuyao Benma specializes in the development and manufacturing of high-performance optical lenses for LED lighting systems. With extensive experience in precision mold design, injection molding, and optical component production, we provide reliable OEM and ODM solutions for global lighting brands, engineering contractors, and industrial buyers.

This 20mm PMMA TIR LED lens is engineered for focused spot lighting applications requiring high optical efficiency and stable beam control. Designed for compatibility with 3030, 3535, and 5050 LED packages, the lens delivers a precise 30° beam angle with transmittance above 90%, helping improve illumination intensity while reducing light loss.

Manufactured using premium PMMA optical-grade material, the lens features excellent transparency, consistent light distribution, and strong dimensional stability. The TIR (Total Internal Reflection) optical structure combines lens and reflector functions into a compact design, making it suitable for modern LED spotlights, track lights, downlights, commercial lighting, display lighting, and architectural lighting systems.

We provide complete custom optical lens solutions, including optical simulation, product structure optimization, precision mold manufacturing, injection molding, surface treatment, assembly, and mass production. Our engineering team can customize beam angles, lens dimensions, mounting structures, and optical patterns according to customer project requirements.

The lens supports glue installation and is designed for stable operation in environments from -40°C to 80°C. With strict quality control standards and advanced molding equipment, we ensure excellent consistency for every production batch.

We support OEM/ODM manufacturing for custom LED optical components and offer rapid sampling, mold development, and overseas project support for customers worldwide.
