The automotive industry is constantly evolving, and with it, the technology used in vehicles. One of the most important parts of any car is the lights, which play a vital role in ensuring safe driving during low-light conditions. In recent years, there has been a new material that can substitute glass in car light production - Optical Liquid Silicone Rubber (LSR). In the past, glass was the go-to material for car light production, but optical silicone has proved to be a better alternative.
When compared to other lens materials, LSR has many advantages.
Firstly, it is lighter than glass, which can help to reduce the overall weight of the vehicle and improve fuel efficiency. And, it's more durable and resistant to damage from impacts and extreme temperatures. This makes them a more cost-effective option in the long run, as they require less maintenance and replacement. It also has a built-in protection level above IP67, which reduces the cost of installation parts and installation and maintenance.
Secondly, its temperature resistance is up to 200℃, making it suitable for use in front of the COB chip where temperatures can reach 150℃ or more after strict testing. Neither PMMA nor PC can meet the temperature resistance requirements.
Thirdly, LSR is environment friendly, and has a high transparency and efficiency rate. Its transmittance is similar to glass, about 94%, which is higher than PMMA. This makes it suitable for optics.
Fourthly, its optical efficiency is higher than that of PMMA and PC. Its consistency is also better than that of glass, and the light output angle is more accurate. This makes it suitable for high-end optical applications.
Lastly, LSR is a better anti-ultraviolet material. It has better properties than PC and PMMA and can resist yellowing outdoors for a long time indoors. With all these advantages, it is evident that LSR has a great prospect in the optical field.
The use of optical silicon lenses in automotive lights is a significant advancement in technology that offers numerous benefits over traditional glass lenses. With their superior durability, optical performance, and environmental friendliness, it is no wonder that they are becoming an increasingly popular choice for car manufacturers. As the automotive industry continues to evolve, it is likely that we will see even more innovative technologies like this being developed to improve safety, efficiency, and sustainability on the road.
