Product Description

Introducing Liquid Injection Molding UV LED Lens Made of Optical Silicone

In the past few years, optical liquid silicone has become a highly sought-after material for UV LED lenses due to its exceptional characteristics. The lens is made from optical liquid silicone, which is processed through silicone injection molding, resulting in a sturdy and long-lasting product. This type of lens is ideal for a variety of industries that demand superior quality lenses for their equipment. Its unique properties make it an excellent solution for those seeking durability and longevity in their lenses. YEJIA has been the top manufacturer of optical silicone lenses in China, welcome custom UV led lenses.


Product Specification

The lens manufacturing industry has been revolutionized by the use of optical liquid silicone. This material possesses exceptional optical properties, allowing light to pass through with minimal distortion, making it an ideal choice for lenses that require clarity. The advanced manufacturing process of silicone injection molding is used to process the UV led lens. This process involves injecting liquid silicone into a mold and curing it to create the desired shape. The result is a lens that is highly uniform and consistent in its shape and dimensions, thanks to the precise control enabled by this process. The use of this technology has allowed for the production of lenses that are of superior quality, delivering excellent performance and reliability. With low density and high fluidity, the optical liquid silicone can achieve many lightweight, complex and micro-structure designs.

UV LED Lens Optical Performance

The light transmittance is over 94% and the refractive rate is only 1.41, which makes the silicon lens has less light loss than other materials, for example, PMMA. UV LED lens made of optical silicone also has many advantages, such as:

Temperature Resistant

In addition to UV resistance, optical silicone UV LED lenses also offer excellent temperature resistance. With the ability to withstand temperatures ranging from -40°C to 200°C, these lenses are suitable for use in a wide range of environments. This temperature resistance makes them a reliable choice for applications where other materials may fail due to thermal stress.


UV Resistant

UV light can be detrimental to many materials, causing degradation and shorter lifetimes. However, the use of optical silicone in UV LED lenses provides exceptional resistance to UV radiation, ensuring consistent performance over time. These lenses maintain their optical properties even after prolonged exposure to UV light, making them an ideal material for use in UV LED applications. 


Explosion Proof

The explosion-proof nature of optical silicone UV led lens makes it an ideal choice for use in hazardous environments where explosions or fires may occur. This non-combustible material does not release toxic gases or smoke when exposed to high temperatures or flames, ensuring safety in critical situations.
