The present invention relates to an LED lamp having an anion generating function, and more particularly, having a body having a socket-type terminal portion formed at the bottom thereof, and including a cylindrical body portion having a plurality of heat dissipation fins protruding outwardly on an outer circumference thereof. Couple the configured heatsink to the upper side of the main body, and install a substrate on which the plurality of LEDs are mounted on the base portion is formed horizontally expanded on the upper portion of the body portion, and the cover is coupled to the upper portion of the base portion, the central portion of the cover A tapered concave tapered concave and a tapered cap having a fitting hole are formed in the center, and a converter for supplying power and an anion generating module for generating anion are installed in the body and the main body. Is inserted so that the end of the anion electrode rod is exposed to the outside of the tapered cap through the fitting hole, and the sound That combines a negative ion generation brush which emits the negative ions to the outside at the end of the electrode part of the negative ion generation brush is configured so as to be exposed to the outside of the tapered cap features. According to the present invention, since the negative ion generating brush for negative ion generation is exposed to the outside of the cover of the LED lamp, the negative ion generated in the negative ion generating brush can be expected to be emitted to a wider area, and also by the tapered cap formed tapered. As the anion electrode is supported, there is a taper cap around the anion generating brush. As a result, the anion generated from the anion generating brush is radiated by the taper surface of the taper cap, which can be expected to be released to a wider area. By installing the negative ion generating means in the LED lamp installed in the lamp, the effect of low power consumption of the LED lamp as well as the
