The technical solution relates to the field of medicine and more particularly to the disinfection means using ultraviolet irradiation, namely bactericidal irradiators and intended for disinfecting air in the passenger compartment. The technical result of the implementation of which is directed technical solution is to improve the sanitary condition of the passenger compartment by disinfecting the maximum volume of air in the cabin caused by ultraviolet radiation on bacteria contained in the air, as well as providing quick and easy installation and locking in the operating position disinfection source. The technical result provided by the fact that the design of the illuminator consists of rods, the keeper of which is fixed casing length lesser than the rod length, with mounted thereon four germicidal mercury lamps, low pressure axes of which are parallel to the rod axis, along the circumference, perpendicular to the rod axis with 90-degree increments power mercury lamp through start-control valves mounted in the housing and a cable entering the enclosure, wherein the cable has a power button switch located on the cable itself. The operating principle of the technical solution: the open window openings opposite the car door in the absence of people in the cabin through one of the window openings set irradiator based bar on the lower edge of the window openings. the power cord is connected to an external power source. The operator using a switch includes an irradiator whereupon low pressure mercury germicidal lamps begin to impact on the surrounding air by radiation of ultraviolet rays with a wavelength of 253.7 nm, destroying viruses, bacteria, spores contained in the vehicle cabin. The technical solution can be applied: - for disinfection of air in the passenger compartment, the following foci of viral infection outbreaks - air disinfection after transport in the car carrier of a viral infection - air disinfection after transportation of animals in the passenger com
