As an optical-grade product, LED lenses have strict requirements on light transmittance, thermal stability, density, refractive index uniformity, refractive index stability, water absorption, turbidity, and high long-term working temperature. Therefore, the lens material must be selected according to actual conditions. Since it is an LED optical lens, the materials used by our company are also optical grade.

At present, our company uses PMMA and PC materials at most. The quality of the lens test that the customer purchases back is completely passed.

Our company has strict requirements on the production workshop, and will inspect and clean the workshop regularly. The product quality is even more demanding: there must be no bubbles, no dents, no sink marks, no flow lines, and no crescent; shape accuracy Rt<0.005 surface roughness Ra<0.0002, LED lens products must be packaged in anti-static and dust-proof PVC. And the package must be completely sealed before being delivered to the customer. Lianlong Optoelectronics strictly controls the selection of materials and guarantees quality to provide customers with high-quality products and services.

  From the above LED lens design and production process, the seemingly simple LED lens, from design to finished product, has very high requirements for software and hardware, which also causes the price of LED lenses on the market to vary greatly. Judging from the bright prospect of LED lighting popularization, the market prospect of lens as an indispensable part of LED lighting lamps will also get better and better.
