Problems solved by technology

[0004] However, discharge tubes such as xenon flash lamps and low-pressure mercury lamps can radiate high-intensity ultraviolet rays, but due to their short lifespan, the discharge tubes need to be replaced periodically, resulting in increased operating costs.

Abstract

This ultraviolet sterilization device comprises: a deep-ultraviolet light source that has at least one deep-ultraviolet light-emitting diode and applies deep-ultraviolet light to an object to be sterilized; and a control means. The control means controls at least one selected from (1) an irradiation time t (unit: second) which is defined as the duration of application of deep-ultraviolet light to the object to be sterilized, (2) the distance d (unit: cm) between the object to be sterilized and the deep-ultraviolet light source, and (3) the light output P (unit: mW) of the deep-ultraviolet light source so that the cumulative dose I (unit: mJ / cm2) of deep-ultraviolet light to be applied to the object to be sterilized within the irradiation time is a predetermined value I0.

Description

technical field [0001] The invention relates to a sterilizing device using ultraviolet rays. Background technique [0002] Unlike sterilization using chemicals, ultraviolet sterilization has no residue, is highly safe, and hardly changes the irradiated object. Therefore, it is proposed to use ultraviolet light sterilization to sterilize objects in various scenarios. [0003] For example, Patent Document 1 describes a conveyor-type sterilizing device using a xenon flash lamp, which is characterized in that an ultraviolet irradiation chamber is provided at a middle position on the surface of the conveyor that transports the object to be sterilized by irradiation with ultraviolet rays. The entrance and exit of the irradiation chamber are connected to the upstream side light-shielding tube part and the downstream side light-shielding tube part with the surface of the conveyor as the bottom surface. In each of the above-mentioned light-shielding tube parts, it is used to make th...
