The star roof of the car originated from the high-end car Rolls-Royce to increase the atmosphere inside the car. A light source transmits various colors of light to the roof through a plurality of light guiding fibers, and emits various soft lighting effects, which are as bright as the stars in the starry sky, but not dazzling. It has the advantages of low energy consumption, safe use and no influence on the warranty of the original car.

In order to achieve better results, a layer of fur roof will be built on the original roof, so that the starry roof will show the effect of twinkling stars at night.

Light weight of optical fiber:

Because the optical fiber is very thin, the core diameter of single-mode optical fiber is generally 4 um ~ 10 um, and the outer diameter is only 125um, plus waterproof layer, stiffener and sheath.

The diameter of optical cable composed of 4 ~ 48 optical fibers is less than 13mm, which is much smaller than the diameter of standard coaxial cable of 47mm. In addition, the optical fiber is glass fiber, which has the characteristics of small diameter and light weight and is very convenient to install.
