[0029] The second one-way valve 29 is installed on the liquid outlet pipe 9, the hollow heat-conducting rubber plate 17 is connected with the refrigeration box 4 through the conveying pipe 8, and the second one-way valve 29 only allows the hydraulic oil in the piston cylinder 23 to be transported into the liquid outlet pipe 9; the air inlet pipe 26 is further connected with the piston cylinder 23, the third one-way valve 27 is installed on the air inlet pipe 26, and the third one-way valve 27 only allows air to pass through the air inlet pipe 26 into the piston cylinder 23.

[0031] When the LED lamp bead 19 is electrified and works, the temperature between the upper cover 12 and the lower cover 14 is increased with the use of the LED lamp bead 19, and the heat between the upper cover 12 and the lower cover 14 can be naturally dissipated through the annular filter plate 6.

[0032] When the temperature between the upper cover 12 and the lower cover 14 is increased, the temperature sensor 28 detects that the temperature is greater than the set value, and the temperature sensor 28 transmits a signal to the controller, and the controller controls the motor 3, the fan 16 and the semiconductor refrigeration sheet 10 to work. The fan 16 can work to exhaust heat between the upper cover 12 and the lower cover 14, and the external air enters between the upper cover 12 and the lower cover 14 through the annular filter plate 6, so that the air at the LED lamp bead 19 is circulated, and the LED lamp bead 19 can be cooled; the annular filter plate 6 can shield dust and flying insects in the air, so that they cannot enter between the upper cover 12 and the lower cover 14, so as not to affect the internal LED lamp bead 19.

[0034] The semiconductor refrigeration piece 10 can cool the heat exchange oil in the refrigeration box 4, the gear 22 drives the connecting rod 25 to move, the connecting rod 25 drives the moving piston 34 to reciprocate, when the moving piston 34 moves towards the motor 3, the heat exchange oil in the hollow heat-conducting rubber plate 17 can be sucked into the piston cylinder 23 through the liquid inlet pipe 30, and part of the air can be sucked into the piston cylinder 23 through the air inlet pipe 26, so that the piston cylinder 23 is filled with heat exchange oil and air. When the moving piston 34 moves away from the motor 3, the heat exchange oil and air in the piston cylinder 23 can be transported into the refrigeration box 4, and the heat exchange oil in the refrigeration box 4 can be transported into the hollow heat-conducting rubber plate 17 through the delivery pipe 8 due to the pressure and gravity. Thus, the flow of the heat exchange oil in the hollow heat-conducting rubber plate 17 can be realized, and the heat on the circuit board 18 can be taken away through heat transfer, so that the circuit board 18 and the LED lamp bead 19 can be effectively cooled to ensure stable operation.

[0035] With the reciprocating movement of the moving piston 34, the air in the refrigeration box 4 increases, causing the pressure in the refrigeration box 4 to increase. Not only can the heat exchange oil in the refrigeration box 4 be extruded to be transported into the hollow heat-conducting rubber plate 17 through the delivery pipe 8, but also the air can be transported into the serpentine exhaust pipe 7. Since the serpentine exhaust pipe 7 is located in the heat exchange oil, the air flowing through the serpentine exhaust pipe 7 can be cooled through heat exchange, and finally, the low-temperature air after heat exchange is discharged through the serpentine exhaust pipe 7, like Figure 4As shown, since the fan 16 is arranged opposite to the serpentine exhaust pipe 7, the low-temperature air flows through the surface of the LED lamp bead 19, so that the LED lamp bead 19 can be cooled and radiated to ensure stable operation.

[0036] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
