Background technique

In the production process of industrial products, it is often necessary to irradiate the objects to be irradiated with ultraviolet light, so as to impart special properties to the objects to be irradiated, such as ultraviolet light curing, ultraviolet light disinfection, etc.

When manufacturing medical infusion tubes, the current domestic UV curing of medical infusion tubes is mainly through mercury lamp irradiation. The mercury lamp irradiation is not uniform. Along the length of the lamp tube, the luminous intensity at both ends is weaker than that of the middle part, so it cannot emit light uniformly. The effect of uniform irradiation of flat objects cannot be achieved, so that the light intensity absorbed by the curing material is different, which affects the curing effect. Medical infusion tubes have high requirements for curing uniformity, and the existing mercury lamps cannot meet the production requirements of medical infusion tubes.

In addition, the adjustability of mercury lamps is poor. The adjustment of the radiation intensity of mercury lamps is generally realized by changing the number of lit lamps in a multi-lamp light source. The corresponding radiation intensity is changed between a limited number of values. The application is not flexible enough. cause a burden.
