The invention discloses an
LED lamp. The
LED lamp comprises an
LED lamp bead, a lampshade, a heat conduction apparatus for fixing the LED lamp bead and a radiator, wherein the heat conduction apparatus is provided with an air
flue; the radiator comprises an
electromagnet, a spring leaf, an armature, a
fan blade with a
flapping wing structure, a one-way flow auxiliary ring and a magnetic-
control switch, wherein the
electromagnet, the magnetic-
control switch and a power supply form a circuit; one end of the armature is connected with the spring leaf, and the other end of the armature is connected with the
fan blade with the
flapping wing structure; the
fan blade with the
flapping wing structure is provided with a plurality of pores; and one end, close to the armature, of the one-way flow auxiliary ring is fixed to the fan blade with the
flapping wing structure. After the power supply is switched on, the
electromagnet attracts the armature to drive the fan blade with the
flapping wing structure to move downwards, so that a seam capable of allowing air to pass through is formed between the fan blade with the
flapping wing structure and the one-way flow auxiliary ring; a permanent
magnet magnetic sheet on the fan blade with the flapping wing structure is in contact with the magnetic
control switch, so that the circuit is switched off; under the action of the spring leaf, the armature drives the fan blade with the flapping wing structure to return, so that the circuit is switched on; and the processes are repeated. The LED lamp actively realizes one-way flow of air, so that the heat dissipation effect is achieved.
