Zusammenfassung:	The utility model belongs to the technical field of lighting lamps and particularly relates to an LED (Light Emitting Diode) lamp. The utility model particularly discloses an LED bulb lamp which comprises a glass lampshade, an LED light source, a base, a switching power supply and a lamp cap, wherein one end of the base is connected with the lamp cap. The LED bulb lamp is characterized by also comprising a heat radiating seat fixed on the base, the heat radiating seat is cylindrical and in an alumina ceramic structure with one end closed, the LED light source is fixed with the heat radiating seat through a metal substrate, the base is a cylinder body made of insulating material through integral forming, the base is positioned in the heat radiating seat and is fixed with the heat radiating seat, and the switching power supply is arranged in the base. According to the LED bulb lamp, the heat dissipation is good, the service time of an LED is prolonged and the energy efficiency is improved.
