Abstract：Objective To investigate the impact of two different lamp holders on the disinfection and sterilization effects of ultraviolet
(UV) disinfection lamps. Methods A total of 54 newly purchased UV disinfection lamps in March 2018 were installed on the new
energy-saving electronic light holder and the old-fashioned induction lamp holder, respectively. The intensity of UV radiation was
detected and the air culture was carried out at the same time. Results The new energy-saving electronic light holder had a significant
influence on the UV disinfection intensity. As the application time passed, the irradiation intensity deceased rapidly, and the
air culture after disinfection showed that the total number of bacteria seriously exceeded the standard. Conclusion The new
electronic lamp holder cannot maximize the UV disinfection intensity, thus it is not suitable for the medical working environments
and the workplaces requiring disinfection of air and object surfaces. The specific requirements of UV air disinfection should be put
forward by national departments, which is urgent and practical significance to prevent nosocomial infection.
