Problems solved by technology

However, because of the exponential attenuation law of ultraviolet light in air and water, it will inevitably lead to a significant decrease in the power of ultraviolet light after long-distance transmission, and a significant decrease in the sterilization and disinfection efficiency, and may even fail to achieve the effect of sterilization and disinfection.

Abstract

The invention discloses an ultraviolet LED sterilization method through optical fiber coupling. The ultraviolet LED sterilization method comprises the following steps that S1, a lens and a collimatorare installed on a packaged ultraviolet LED; S2, the ultraviolet LED light emitted from the collimator is close to collimated parallel light; S3, the parallel light can be subjected to arranging and installing after coupling and collimation of the plurality of beams of optical fibers according to a parallel line shape; and S4, the ultraviolet LED coupling light sources arranged in the parallel line shape can be made into a sterilization and disinfection device. The device has the following beneficial effects: (1) the device can be mounted on various sterilization and disinfection devices; (2)efficient sterilization and disinfection can be realized in a short distance and a long distance, and the application scene is infinitely broadened; (3) the divergent LED light is coupled into collimated parallel light through the optical fiber, which is simple and easy to implement; (4) required lenses, collimators, light bunchers and light splitters are easy to obtain; (5) the luminous intensityloss of the ultraviolet LED after optical fiber coupling is very small; and (6) the long-distance light attenuation is less, and the method can be applied to many large-space sterilization and disinfection fields.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet sterilization, and in particular relates to an ultraviolet LED sterilization method and device through optical fiber coupling. Background technique [0002] With the advancement of science and technology, the continuous development of the manufacturing industry, the standard of living has also been continuously improved, and both material life and spiritual life have been greatly improved. However, in recent years we have also encountered an embarrassing situation. Although the living standard has improved, the environment has deteriorated day by day. The aggravation of smog and water pollution has added flaws to the ever-improving living standards, and the bacteria and viruses carried in the air and water are eroding our health. The novel coronavirus that emerged in 2019 has ravaged the world, and life has become more vulnerable to this virus. The number of deaths caused by the virus is unpr...
