Zusammenfassung:	The utility model relates to a radiator for an LED (light emitting diode) bulb lamp and the LED bulb lamp applying the radiator, and belongs to the technical field of radiators for LED bulb lamps. The radiator for the LED bulb lamp comprises a radiating cover, wherein both the internal surface and the external surface of the radiating cover are trumpet-shaped; a plurality of grooves in an axial direction are formed in the internal surface of the radiating cover; and radiating fins are convexly formed at the parts of the external surface of the radiating cover, corresponding to the grooves in the internal surface of the radiating cover. The grooves and the radiating fins increase the internal and external surface areas of the radiating cover effectively, so that the radiating efficiency of the radiating cover is improved. The LED bulb lamp comprises a lamp head, the radiating cover, an insulating component, an LED lamp, a heat-conducting circuit board, a lampshade and the like, wherein the radiating cover can
