Optical fiber lighting LED cold light source

------- Fiber optic light source conduction to any area is a high-tech lighting technology (Jacket) that has emerged in recent years.

In the application of the mature stage, in the field of high-speed transmission communication, is widely used. The most popular application of early optical fiber lighting cold light source is the jewelry made of optical fiber catheter. The structure can be briefly divided into three parts, namely Core, Cladding and Jacket.

Its conductor is mainly made of glass material (SiO2) wire, its transmission is the use of high refractive index medium, at an Angle higher than the critical Angle into the low refractive index medium will produce total reflection principle, so that optical fiber lighting cold light source in this medium can maintain the characteristics of the light waveform for transmission. The core part of the high refractive index is the main channel for fiber optic LED lighting module transmission. The low-refractive index shell covers the entire core, because the refractive index of the core is much higher than the shell, so it will produce total reflection, and therefore can be transmitted in the core. The purpose of the protective layer is mainly to protect the shell and core from damage, but also to increase the strength.

The application method in lighting is divided into two kinds, one is light and the other is light. The luminous part is mainly composed of two components: the light projection host and. The projection host includes a reflector mask and a color filter. The main purpose of the reflector is to increase the intensity of the light, while the color filter can carry out the evolution of the color and transform the different effects. Luminescence is itself a luminous body, which will form a flexible light strip.

Most of the optical fibers used in the lighting field are plastic fibers. In different materials, the production cost of plastic is the cheapest, and compared with quartz fiber, it is often only one-tenth of the production cost. Because of the characteristics of the plastic material itself, whether it is post-processing or the variability of the product itself, it is the best choice for all optical fiber materials. Therefore, the use of lighting, plastic fiber is selected as the conduction medium.
