Zusammenfassung:	A high-radiating-performance light-emitting diode (LED) bulb lamp comprises a lamp holder, a bulb casing, a heat-conduction column and a plurality of LED light sources arranged on the heat-conduction column. The heat-conduction column is fixed at the top of the lamp holder, the bulb casing is a ball bulb casing, a heat transfer portion is arranged at the bottom of the heat-conduction column, and a connection portion is arranged on a bottom opening of the bulb casing at the position corresponding to the heat transfer portion of the heat-conduction column, the connection portion is in heat connection with the heat transfer portion, and the heat-conduction column and the bulb casing are fixed on the lamp holder. The high-radiating-performance LED bulb lamp has the advantages of being simple in structure and good in radiating effect.
