Fiber optic is polymerized from liquid polymer compounds, with strong optical conductivity, power saving, durability, non heating, pollution-free, bendable, color changing, wide environmental adaptability, and safe use. The light guiding methods of optical fibers are divided into soft and warm linear optical fibers and sparkling point optical fibers, which are widely used in various decoration and lighting projects such as building decoration lighting, landscape decoration lighting, cultural relics and handicrafts lighting, special occasions lighting, billboards, entertainment venues, and so on. Optical fiber types include ordinary solid line optical fiber, PVC solid core optical fiber, thermoplastic solid point optical fiber, and PVC solid core point optical fiber.

When the light source passes through the reflector, it forms a beam of approximately parallel light. Due to the effect of the color filter, the beam is transformed into colored light. When the beam enters the optical fiber, colored light follows the path of the fiber to the predetermined location. Due to the loss of light in transit, light sources are generally very strong. The commonly used light source is around 150-250W. And in order to obtain an approximate parallel beam, the emission point should be as small as possible, similar to a point light source.
