The full-body luminous optical fiber is a new type of optical fiber that can achieve uniform luminescence of the entire optical fiber. It is generally composed of a high-refractive index core material and a low-refractive index skin material. The light is refracted and reflected multiple times during transmission to achieve full-body luminescence. It has the characteristics of good flexibility and can be shaped at will, safe and non-electric, energy-saving, rich and varied colors, and long life. The production requires multiple processes such as raw material processing, stretching heat treatment, and coating. It is widely used in indoor and outdoor decoration, advertising signs, landscape lighting, stage performances, automotive interiors and other fields, adding unique visual effects and practical functions to each scene.

The fiber optic starry stars in the swimming pool is a lighting system used for swimming pool decoration. The light from the light source is transmitted to the underground lamps of the swimming pool through the optical fiber, creating a dreamy effect like a sky full of stars.
