LSR Injection Molding UV Resistance& High Temperature Resistance Silicon TIR Lens for LED Lighting
Silicon TIR Lens is made of optically clear LSR liquid silicon, processed by liquid injection molding in class 100,000 clean production workshop, our factory has been the top manufacturer of silicone molding optical TIR lenses in China.
This optical silicon TIR lens is made of ultra transparent imported optical liquid silicone, processed by LSR injection molding, with excellent performance in demanding harsh environments, such as, high heat, high humidity and UV exposure. TIR lenses, which means total reflection technology+ inter-media action, each light ray is utilized in a controlled manner, generally without secondary light spots and with a good looking light pattern.

TIR Lens uses the principle of total reflection to collect and process light. It is designed to collect and reflect all the side light in front of the lens in a penetrating way, while the tapered surface collects and reflects all the side light, and the overlapping of these two types of light results in a perfect light utilization and a beautiful spot effect. The efficiency of TIR lens can reach over 90%, with the advantages of high light energy utilization, low light loss, small light collection area and good uniformity.
Silicon TIR Lens Optical Performance
The optical liquid silicone has low refractive ratio at 1.41 and high light transmittance of 92%, with great flexibility and low viscosity, the silicon TIR lens can achieve micro-structure and under-cut designs. With characteristics of anti-yellowing, UV resistance and temperature resistance, the optical LSR TIR lens keeps no change after 5000 hours aging testing, and the silicon TIR lens can work under temperature over 200 degrees Celsius. With lower density than PC, PMMA and glass, the silicon tir lens weight is way much lighter than other optical lenses.
