Product Information

Silicon TIR lens also known as total internal reflection lenses, which are used to collect and process light using the principle of total reflection, use Tracepro software to trace the light passing through the silicon TIR collimator, resulting in a light energy utilisation of 95.26% and a beam divergence angle of 15° or less. LSR optical silicone lens can improve the utilization rate of LED light energy. Silicon TIR collimator lens designed to use penetrating focusing in the front, and the conical surface can collect and reflect all side lights. The overlap of these two kinds of lights can achieve perfect light utilization and beautiful spot effect. Optical grade silicone LED lens reflector or silicon TIR collimator can be used for high power long-time lighting. 

Silicon TIR Lens For LED Illumination Optics

The material of silicone LED lens reflector is silicone optical is a two-component ultra high transparent liquid silicone rubber material, which has good optical properties and flame retardancy. For this style silicone LED lens reflector, we use Momentive LSR7080 material, hardness is 80 Shore A, transparent color, processed by ARBURG Horizontal LSR Injection Molding Machine.The transmission of silicon LED lens reflector can reach more than 94%, which has the advantages of high light energy utilization, low light loss, small light collection area, and good uniformity. Optical grade silicone lens has the function of total reflection technology+medium, every light ray all can be controlled and used, generally there is no secondary spot, and with a good looking light pattern. All in all, the silicon TIR lens has features of UV Resistant,Yellowing Resistant, Easy Demoulding, lightweight, effcient in light distribution, etc. If you're looking for custom silicon lens, welcome to contact us.

FAQ

  • 1

    What’s the advantage to choose liquid silicone to make optical lenses?

    Comparing to Plastic, the properties of light transmittance, anti-yellowing and weathering resistance are better. Comparing to Glass, the optical liquid silicone is easy to shape, the fluidity makes the complex or micro-structure designs moldable.

  • 2

    What’s the level of your clean production workshop?

    Currently, for Liquid Injection Molding, the workshop is Class 100,000, while for plastic, our factory has Class 10,000, or even Class 1,000 clean workshops.

  • 3

    Can you design the optical linear lenses?

    For now, we just do OEM designs. Our team is unable to do the product design.

  • 4
