The present invention relates to a lightweight piece of LED lighting fixture having a sterilizing function. The LED lighting fixture includes a plurality of light emitting parts spaced apart from each other by irradiating a light source to a plurality of LED chips integrated on a PCB substrate, An upper portion of the mounting substrate is connected to a lower portion of the light emitting portion and a lower portion of the mounting substrate is connected to an upper portion of the mounting substrate so that the light emitting portion is spaced apart from the upper portion of the mounting substrate, And at least one radiating fin for radiating heat generated from the light emitting unit and discharging and guiding the surrounding air to the mounting substrate and the mounting substrate and the light emitting unit, A case having an empty space for easily exchanging heat with air, a transparent case disposed on the case to protect the light emitting unit, As characterized in that the a,； by generating the hydrogen peroxide, hydroxyl ions, excess oxide ions are formed in the center of sterilizing harmful bacteria of the mounting substrate sterilizing means to diffuse into the surrounding； Hydrogen peroxide, hydroxyl ion, and excess oxide ions that attack and kill harmful bacteria (pathogens) through the hydrolytic ionization through the hydrophilic metal catalysis of the UV lamp and the coating layer coated on the sterilization net of sterilization means are produced, Can be widely diffused to the surroundings through the wind of the blowing fan to sterilize harmful bacteria remaining in the surroundings, so that the light source can be provided through the light emitting part, and the harmful bacteria can be eliminated by the sterilizing means, There is an effect that can be comfortably and advantageously created. Further, by guiding the wind supplied from the blowing fan to the discharge hole of the transparent panel through the guide plate, the ions generated throug
