The present invention relates to an LED unit for sterilization, antibacterial action and drying, and for extermination of drosophilas, and particularly comprises: an LED module in which a plurality of ultraviolet LEDs and infrared LEDs are arranged a driving unit for driving the LED module and a fixing unit for fixing the LED module at a predetermined installation location, wherein the ultraviolet LEDs and the infrared LEDs respectively have a wavelength in the range of 380-410 nm and 700-1,500 nm, and are arranged at a number ratio of 1:0.1-5 whereby it is possible to perform sterilization and antibacterial action by long-term irradiation of ultraviolet rays, having low energy, that are harmless to the human body, and simultaneously perform a weak sterilizing and antibacterial function and a heat dry function by irradiation of infrared rays, which are heat rays, during the long-term irradiation of ultraviolet rays. Also, it is possible to exterminate harmful insects capable of sensing infrared rays, such as drosophilas, by blocking the induction of the harmful insects by inducing avoidance through photoperiod recognition. In addition, when an object is mounted on a mounting rod after fixing a frame comprising the LED module using a support unit at various installation locations such as a bathroom, a kitchen, a shoe rack or a laundry drying rack, there is an advantage that sterilization, antibacterial action and drying of the object can be easily performed.La présente invention concerne une unité à LED pour une stérilisation, une action antibactérienne et un séchage, et pour lextermination de drosophiles, et comprend en particulier : un module à LED, dans lequel une pluralité de LED à ultraviolet et de LED à infrarouge sont disposées une unité de commande pour commander le module à LED et une unité de fixation pour fixer le module à LED en un point dinstallation prédéterminé, les LED à ultraviolet et les LED à infrarouge ayant une longueur donde comprise respectiv
