After heat on the lamp plate conducts to the radiating fins, the fan blade is driven to rotate through the motor, air in the air pipe is discharged through the through holes in the bottom plate through the fan blade, negative pressure is formed inside the air pipe, air in the luminous cavity enters the air pipe through the air outlet due to the negative pressure, negative pressure is formed in the luminous cavity, air between the air pipe and the shell enters the luminous cavity through the air inlet hole, air flowing is achieved through rotation of the fan blade, heat transfer occurs between the air and the radiating fins after the air passes through the radiating fins, the heat on the radiating fins is discharged through the through holes in the positions of the air pipe after being absorbed by the air, and the heat produced by the lamp plate can be effectively discharged out of the shell.

Preferably, the baffle plate is further provided with a baffle plate arranged around the lower half part of the radiating fin. Through the baffle effect, the air enters into the radiating fin position and contacts with the radiating fin from the lamp plate with radiating fin's contact position, can effectively prolong the contact time of air and radiating fin.

Compared with the prior art, the utility model has the following advantages:

rotate through the flabellum and realize that the air flows, the air takes place the heat transfer with radiating fin behind radiating fin, and the heat on the radiating fin is discharged through the through-hole of tuber pipe position after being absorbed by the air, can be effectively with outside the heat exhaust shell that the lamp plate produced.
