Zusammenfassung:	The utility model provides an all-periphery light-emitting LED bulb lamp and relates to the technical field of LED lamps. The all-periphery light-emitting LED bulb lamp structurally comprises a radiator with the upper portion provided with a cylinder and a columnar circuit board with the inside provided with a cavity. The shape of the columnar circuit board is matched with the shape of the upper portion of the radiator, the columnar circuit board sleeves the upper portion of the radiator and comprises a side wall and the top surface, and the top surface and the side wall are provided with a plurality of LED lamp beads. According to the all-periphery light-emitting LED bulb lamp, the columnar circuit board with the inside provided with the cavity is modified based on the a plane circuit board in the prior art, the upper portion of the radiator is designed into the cylinder matched with the shape of the circuit board, so that the circuit board can sleeve the radiator, the inside space of the bulb lamp can be saved, and the bulb lamp is more compact in structure and good in heat dissipation effect; the circuit board can be fixed on the radiator without needing extra fixation of the circuit board, and the cost is reduced.
