Optical fiber illumination light source end coupling system

Abstract

The invention discloses an optical fiber illumination light source end coupling system which comprises a light screen. The service life of the optical fiber illumination light source end coupling system is prolonged, the components such as a coupling end optical fiber and a lens are prevented from burning and melting due to long-term use, and the aging time of the optical fiber is greatly prolonged. In addition, the optical fiber illumination light source end coupling system is high in light emitting efficiency and coupling efficiency, and can be productized and applied to large-scale production, transportation and installation. The system is not damaged or affected in use by the general jitter and displacement.

Description

technical field [0001] The invention relates to the field of optical fiber lighting applications, in particular to an optical fiber lighting light source end coupling system. Background technique [0002] The existing optical fiber lighting system (including collimation coupling) is mainly composed of light source, lens, optical fiber, fixed structural parts, power supply, etc. After the light source emits light, the light beam is gathered into a relatively small angle through the lens, and passes through a small air gap or zero air gap , to project light to one end of the fiber, so that the fiber optic lighting system works. Optical fiber lighting can achieve photoelectric separation, and has great application value in occasions that require fire prevention and leak prevention, such as petroleum, chemical, swimming pools and other occasions. [0003] But in practical application, there is a very big problem in working with fiber optic lighting system, that is, fiber burnin...

AI Technical Summary

Problems solved by technology

The light efficiency is high at close distances (close to 60%), but the optical fiber will be melted, and the optical fiber at the coupling end will be melted in a short period of time (at room temperature, about half a month), which will cause the entire lighting system to fail to work at all.

And in the fiber optic lighting system, by setting the air gap, it is very inconvenient during transportation and installation. A little carelessness or shaking can cause the parts to shift, resulting in damage to the lighting system, so the fiber optic lighting system, especially the collimated coupling Optical fiber lighting light source end coupling system is not widely used, and the productization is not high
