Optical Liquid Silicone Rubber

Optical Liquid Silicone Rubber for LSR Molding Silicon Lenses

Optical liquid silicone rubber (LSR) is a highly specialized material that finds its application in the production of optical components. Its high light transmission rate of up to 96% makes it an ideal material for use in automotive headlights that require high-power light sources. Moreover, optical LSR offers excellent resistance to both ultraviolet and blue light, making it highly durable and long-lasting for headlight construction. This material's high light transmission rate ensures optimal visibility, making it easier and safer for drivers to navigate the roads. Additionally, the material's resistance to ultraviolet and blue light helps prevent damage and discoloration over time.


To optimize the performance of LED systems in general vehicle models, it is important to address the issue of lens aging caused by high temperatures and radiation. The temperature of the light can reach up to 150°C, which can accelerate the aging of optical plastic lenses and reduce the lifespan of the system. However, this problem can be solved by using silicon lenses that offer physical stability and prevent yellowing. By adopting silicon lenses, we can ensure that the LED systems in vehicles remain efficient and durable, providing reliable lighting solutions for drivers and passengers.

Silicon lens headlamps offer a wider, more uniform, and brighter low-beam illumination range when compared to halogen headlamps. The dipped beam of silicon lens headlamps has more obvious light and dark cutting lines, and its strong lighting effect doesn't affect the sight of oncoming traffic during night driving. Additionally, silicon lens headlamps outperform halogen lamps in terms of high beam illumination.


The mechatronic silicon lens changing system is far superior to halogen headlights when it comes to switching between near and far light. Not only does it have a lightning-fast switching speed, but it also makes driving at night much safer.


Optical LSR's low viscosity and low injection pressure make it an ideal material for layering and injection molding directly onto the LED chip, enabling manufacturers to reduce production costs. By using optical LSR, the process becomes more efficient and cost-effective, without compromising on quality or performance.


The potential for future applications of optical LSR is vast, thanks to its impressive properties. These materials are transparent, resistant to cracking under stress, and can be economically manufactured in complex geometries. With such qualities, the possibilities are limitless for this highly transparent material.


Optical liquid silicone rubber is a game-changer in the production of optical components. Its use in automotive headlights has revolutionized the way we think about lighting solutions in vehicles. With its impressive properties and potential for future applications, it is clear that optical LSR will continue to play a significant role in the development of new technologies in the years to come.
