The invention provides an LED bulb which comprises a lamp cap, a lamp holder, a light source module provided with an LED and a circuit board and a radiating column that is used for realizing omnibearing lighting angel by increasing the height of a light source and has the function of radiating; wherein, the lamp holder is a radiator, one end of which is connected with the lamp cap, and the other end is provided with the radiating column; the free end of the radiating column is fixed with the light source module; thus, the radiating column can heighten the position of the light source to shift the light source out of the lamp holder and increase the irradiation angle of the light source, thus realizing approximate 360-degree lighting effect of the LED bulb and improving the defect that the light rays of the LED are blocked out by the lamp holder since the LED is installed at the rear part of a base plate of the lamp holder, close to the horizontal direction; the radiating column also has the function of radiating, so that the heat generated by the LED in the working period can be quickly transferred to the radiating aluminum lamp holder contacted with the air through the radiating column, thus enlarging the radiating area, fully guaranteeing the radiating requirements and the service life of the LED, reducing the weight of the high-power LED bulb and not increasing the size of the bulb.
