In both patents, the light diffusion is realized by destroying the surface protective layer of the polymer optical fiber, although some protection is provided. The device avoids the deformation of the fabric, but the existence of gaps in the light is also affected by impurities such as water vapor and dust in the air, so the product cannot achieve a long service life.
