The invention discloses an LED lamp filament bulb provided with heat radiation rings. The LED lamp filament bulb provided with the heat radiation rings comprises a lamp base assembly provided with a driving assembly. The lamp base assembly is connected to a bulb shell. A wire support is arranged in the bulb shell. A plurality of electric connecting wires connected with the driving assembly are arranged on the wire support. Two or more heat radiation rings which are attached to the inner wall of the bulb shell are arranged in the bulb shell. Each heat radiation ring is composed of two semicircles provided with chord ribs. A heat radiation support is arranged in each heat radiation ring. LED lamp filament assemblies are connected between the chord ribs of every two adjacent heat radiation rings. According to the LED lamp filament bulb provided with the heat radiation rings, the light emitting rate of LEDs can be increased, and the heat dissipation efficiency can be improved; the limitation that an existing LED illuminating lamp needs a radiator can be broken, a light source of a high-power LED filament lamp can be obtained and can directly replace a light source of an existing high-power illuminating product, and lamp replacement is not needed.
