The invention relates to means of disinfection by ultraviolet radiation and is aimed at improving convenience, reliability and safety of the air disinfection and contaminated surfaces, preferably in medical areas in the absence of people using bactericidal irradiator open type. Bactericidal irradiator comprising housed in the box body supply and control unit, discharge mercury lamp of low pressure sided pin fixed in chucks arranged on the upper surface of the housing, the power supply and control contains a block of network switching, the control unit adapted to function delay time master and operating a discharge lamp, and a power unit electronic control unit to which are connected discharge mercury lamps. Thus on the upper surface of the housing are fixed guard in the form of a lattice placed around HID mercury lamps, and the B-pillar provided with clamps fixing discharge mercury lamp, and is fastened to the body handle. network switching unit configured as a series-connected pushbutton latching and normally open contacts, pushbutton emergency shutdown without fixing with normally closed contacts, a source of low voltage and a push-button momentary normally-open contacts, the control unit comprises a microprocessor connected to the low supply voltage selector switch and operating modes, with the inputs of the microprocessor are connected, push-button th switch without fixation and multi mode switch and to the output of the microprocessor connected to the input of the control electronic ballast signal, wherein the power unit further comprises a controller, whose input is connected to the electronic ballast, and an output connected to the input of the microprocessor, in addition, the outputs a microprocessor connected adders discharge lamp operating time counter and the counter number of switching unit indicator lights and audible warning unit.Полезная модель относится к средствам дезинфекции с помощью ультрафиолетового излучения и направлена на повышение удобства,
