The invention relates to disinfectants using ultraviolet radiation, namely bactericidal irradiators open type with several germicidal mercury discharge lamps of low pressure, and is aimed at improving the efficiency of germicidal air disinfection by reducing the shadow zones and reduce exposure illuminator dimensions.Bactericidal irradiator comprises a central vertical strut with upper and lower lamp holders, cartridges, in which around the central fixed rack discharge low-pressure mercury lamps connected to the power supply, the longitudinal axes of which are arranged obliquely to the vertical axis of the central pillar, the distance from the lower lampoderzhateley- cartridges to the vertical axis of the central pillar is greater than the corresponding distance from the top of bulb-cartridges to the vertical axis of the central pillar. Further, the upper and lower lampholders-cartridges each discharge low-pressure mercury lamp lie in different vertical planes passing through the vertical axis of the central strut and the longitudinal axis of the discharge low-pressure mercury lamps are arranged with an inclination to a vertical plane passing through the vertical axis of the central rack and a lamp holder cartridge each low-pressure mercury discharge lamp. The central vertical strut with a mercury low-pressure gas discharge lamps can be mounted on the housing cover, which accommodates the power supply. In this case the housing cover, which accommodates the power supply is provided with a reflective surface.Полезная модель относится к средствам дезинфекции с использованием ультрафиолетового излучения, а именно к бактерицидным облучателям открытого типа с несколькими бактерицидными газоразрядными ртутными лампами низкого давления, и направлена на повышение эффективности бактерицидного обеззараживания воздуха за счет снижения теневых зон облучения и уменьшения габаритов облучателя.Бактерицидный облучатель содержит центральную вертикальную стойку с верхними и нижними ла
