However, in the hot summer, the glass window makes the driver suffer from high temperature, which is from the sun's infrared rays. And the ultraviolet rays in the sunlight also make the driver's expose to skin disease. If serious, it can also lead to skin cancer. In other words, the driver's health is seriously threatened. In addition, ultraviolet light can easily age the seat and accessories in the car. Certainly, you can open up the air conditioners to cool the room. But, it consumes much energy in the entire summer. What worse, there are so many cars. Obviously, this is contrary to the global energy conservation and emission reduction. Therefore, while protecting the health of the driver, we usually hope to reduce the energy consumption. This is the meaning of the existence of energy-saving films such as smart film of nano particle size violet tungsten oxide.
