through the transmission of the optical fiber, the light source can be transmitted to any area, is the rise of high-tech lighting technology in recent years.

 In the application of optical fiber lighting LED cold light source into the mature stage, in the high speed transmission of the communication field, is widely used. In the early optical fiber lighting cold light source, the most popular application of the cold light source is the decoration of the fiber optic catheter. The structure of the optical fiber LED lighting module can be divided into three parts, namely, the core (Core), the outer shell (Cladding) and the protective layer (Jacket).

The conductor optical fiber LED lighting module itself is mainly made of glass material (SiO2) by spinning and made its transmission is high refractive index using optical fiber lighting LED cold light source into the medium, the principle of low refractive index will produce higher than the total reflection critical angle, make the optical fiber lighting cold light source to maintain the characteristics of optical wave the transmission in the medium. The core part of the high refractive index is the main channel for the transmission of the optical fiber LED lighting module. The low refractive index of the shell, then cover the entire core, due to the core of the refractive index is much higher than the outer shell, so it will produce a total reflection, optical fiber lighting cold light source can also be in the core to transfer. The purpose of the protective layer is mainly to protect the shell and the core is not easy to damage, but also can increase the strength of the optical fiber LED lighting module.

The application optical fiber LED lighting module in the lighting is divided into two kinds, one is the optical fiber lighting LED cold light source, the other is the optical fiber lighting cold light source. The part of the optical fiber lighting LED cold light source is mainly composed of two components: the light projection host and the optical fiber LED lighting module. The host includes a projection light source, fiber optic lighting cold reflector and a color filter. The main reflector is designed to increase the intensity of illumination, and the filter can be the evolution of color transformation, different effects. Optical fiber lighting cold light source is the optical fiber LED lighting module itself is a light emitting body, will form a flexible light.

The optical fiber LED lighting module used in the lighting field is mostly made of plastic optical fiber. In the material of different optical fiber LED lighting module, plastic optical fiber LED lighting module is the most expensive production costs, compared with the quartz fiber, often only 1/10 of the production cost. And because of the characteristics of the plastic material itself, whether in the post processing or the product itself can be changed, is the best choice for all fiber material. Therefore, the optical fiber LED lighting module is used for lighting, and the plastic optical fiber is selected as the conducting medium.
