In life, have you seen fiber optic lighting, if not, today the Fiber Optic Splice Closure  manufacturer talks about what is fiber optic lighting and its features: The fiber optic illumination system consists of a light source, a mirror, a color filter, and an optical fiber. When the light source passes through the mirror, a bundle of approximately parallel light is formed. The light beam is turned into colored light due to the action of the color filter. When the beam enters the fiber, the colored light is sent to the intended location along the path of the fiber. The light source is generally strong due to the loss of light on the way. Commonly used light sources are around 150~250W. Moreover, to obtain an approximately parallel beam, the point of illumination should be as small as possible, similar to a point source. Mirrors are an important factor in the ability to obtain approximately parallel beams. Therefore, aspherical mirrors are generally used. A color filter is a part that changes the color of a beam. According to the need, the corresponding color light source is obtained by changing the filters of different colors. Optical fiber is the main body in a fiber-optic lighting system. The function of the fiber is to transmit or transmit light to a predetermined place. The optical fiber is divided into two types: end light emission and body light emission. The former is that after the beam is transmitted to the endpoint, it is illuminated by the tail light, and the latter itself is the illuminator, forming a flexible beam. For fiber optic materials, it must be in the visible range, the loss of light energy should be minimized to ensure the quality of the illumination. However, it is practically impossible to have no loss, so the fiber transmission distance is preferably about 30 m. The optical fiber has three types: single-strand, multi-strand, and mesh. For a single-strand fiber, its diameter is Ф6～Ф20mm. It can be divided into body light and end light. For multi-strand fibers, they are all end-emitting. The diameter of a multi-strand fiber is generally Ф0.5 to Ф3 mm, and the number of strands is usually several to hundreds. The mesh fibers are composed of thin-diameter bulk-emitting fibers, which can constitute a flexible optical strip.
