[0002] The traditional LED lamp structure includes LED lamp beads, circuit boards, bases, radiators, etc.; LED lamp beads are installed on the circuit board, and heat transfer and heat dissipation are carried out between the circuit board and the base through thermal silica gel, and the base is generally attached to the base. Closed on the radiator, the heat is dissipated through the radiator; in order to ensure sufficient heat dissipation area, the volume of the radiator is generally made relatively large, and the part where the radiator contacts the base is usually made of solid material for heat conduction; Fins for heat dissipation are arranged around the solid material; although the thermal conductivity of this solid structure is higher than that of a hollow structure radiator; but this kind of lamp is relatively heavy and requires high strength for the installation position; The amount of raw materials used in the radiator is relatively large, resulting in high material costs for the radiator

The invention relates to the technical field of lamps, in particular to a radiator structure applied to LED lamps. The radiator structure is characterized in that a circuit board and an aluminum substrate are fixed in a lampshade; LED lamp beads are evenly and circumferentially distributed on the circuit board; the other end face of the aluminum substrate is adhered to the outside of a sealing end face of a radiating shell; the lampshade is fixed on the outside of the sealing end face of the radiating shell; a plurality of external transmitting heat fins are arranged on the outside wall of the radiating shell; a plurality of internal transmitting heat fins are arranged on the inside wall of the radiating shell, and an outer locking thread is in threaded connection with an internal ring thread; an outer sealing ring is pressed between a sealing cover plate and the radiating shell. During use of the radiator structure, heat transmitted from the LED lamp beads is transferred to the sealing end face of the radiating shell via the aluminum substrate and then transferred to the outer transmitting heat fins via the inner transmitting heat fins and the side wall of the radiating shell to be emitted to the air finally; under the situation that heat-conducting property of a radiator is guaranteed in structure, weight of the radiator is reduced, and material cost of the radiator is lowered.
