Description

Fiber conduit structure

The present invention relates to the structure of a fiber optic conduit, and more particularly to the structure of a fiber optic conduit in which a hole is provided in the outer layer of the fiber optic conduit.

Optical fiber (also known as optical fiber) is a fiber made of glass or plastic that uses light to transmit light in these fibers on the principle of total reflection. The tiny fiber is encapsulated in a plastic sheath so that it can bend without breaking. Typically, a transmitting device at one end of the fiber transmits a light pulse to the fiber using a light emitting diode or a laser beam, and the receiving device at the other end of the fiber detects the pulse using the light sensitive element. A cable containing an optical fiber is called a fiber optic cable. Since the transmission loss of information in the optical fiber is much lower than that of the electric conduction in the electric wire, and because the main raw material is bismuth, the reserves are extremely large and easy to mine, the price is very cheap, and the optical fiber is used as a long-distance information transmission. medium. As the price of fiber is further reduced, fiber is also used for medical and recreational purposes.

The optical fiber is a double structure, the core part is a high refractive index glass, and the surface part is a low refractive index glass or plastic. The light is transmitted in the core part, and is continuously totally reflected at the surface boundary, and is transmitted forward along the zigzag shape. This fiber is slightly thicker than the hair, and such a fine fiber has a double structure distribution with a completely different refractive index, which is an amazing technique. After years of efforts, scientists from various countries have created the internal adhesion method, MCVD method, VAD method, etc., and made ultra-high-purity quartz glass. The efficiency of the specially made optical fiber to transmit light has been significantly improved. Nowadays, the optical transmission loss of a better optical fiber is only 0.2 dB per kilometer; that is to say, only 4.5% is lost after one kilometer of propagation.

The characteristics vary slightly depending on the materials used. Among them, glass fiber is more suitable for optical communication such as data transmission, and has gradually replaced traditional wire and cable; plastic fiber has better flexibility than glass fiber. It is not easy to break, and it can reduce the cost by mass production. Therefore, in addition to the use of the fiber itself, it is easy to produce other various uses, such as: using the light guard function of the optical fiber, at least it has: visual or surveillance lighting, The light energy device, the light sensor illumination, the light guide between the object and the light sensor are classified, and the light guide for the visual or monitoring illumination has various usage modes earlier, such as the size measurement of the precision processing machine. Illumination, medical surgery, or dental drill illumination, etc., are being used almost at the same time as the production of plastic optical fibers (POF).

However, when the optical fiber is used for illumination, the illumination effect is often unsatisfactory because of insufficient brightness, especially after the optical fiber is bent, the bent portion of the optical fiber may even have a dark region with a significantly reduced brightness. How to improve the above problems is the direction of this new research.

The main purpose of the present invention is to provide a structure of a fiber optic conduit, which is provided with holes for the outer layer of the optical fiber to increase the brightness of the optical fiber conduit and to make the light extraction rate more uniform.
