AI Technical Summary

Technical Problem

Existing UV disinfection boxes face challenges in maximizing pathogenic microorganism killing efficiency while minimizing the number of sources and process time, especially for disinfecting 3D objects, and addressing issues related to thermal management and plastic degradation from UV exposure.

Method used

A UV disinfection box system with movable walls and high reflectivity, featuring UV sources on adjacent walls inclined towards the bottom wall, a UV-transmitting support positioned between the bottom and upper walls, and high-reflectivity and high-transmittance materials, ensuring uniform UV irradiance across all surfaces.

Benefits of technology

Achieves effective disinfection of 99.9% in a single cycle with low power energy, even on surfaces not directly facing a UV source, using UV-C LEDs and mercury-free lamps, with improved reflectivity and transmittance materials.

Abstract

The box-type UV disinfection system (100) comprises a plurality of internal UV sources (121, 122, 131, 132, 141, 142) arranged on at least two adjacent walls (120, 130, 140), all of whose internal wall surfaces have a reflectance of more than 80%, preferably more than 87%, in the wavelength range of 250-350 nm, and a UV-transparent support (101) having a UV transmittance of at least 70% in said wavelength range and located at a suitable minimum distance from the bottom wall (110), the UV sources (131, 132, 141, 142) arranged on at least one of the walls (130, 140) being inclined towards the bottom wall (110) at an angle of 5°-30°. Such a system has improved properties in terms of efficiency and, in a preferred embodiment, also better portability.
