[0009] Preferably, a liquid inlet pipe and a liquid outlet pipe are installed on the piston cylinder, the liquid inlet pipe is connected to the hollow heat-conducting rubber plate, the liquid outlet pipe is connected to the refrigeration box, a first one-way valve is installed on the liquid inlet pipe, a second one-way valve is installed on the liquid outlet pipe, and the hollow heat-conducting rubber plate is connected to the refrigeration box through a delivery pipe.

[0010] Preferably, it further comprises an air intake pipe, the air intake pipe is connected to the piston cylinder, and a third one-way valve is installed on the air intake pipe.

[0011] Preferably, the first one-way valve only allows heat exchange oil to enter the piston cylinder through the liquid inlet pipe, the second one-way valve only allows hydraulic oil in the piston cylinder to be transported to the liquid outlet pipe, and the third one-way valve only allows air to enter the piston cylinder through the air inlet pipe.

[0013] Preferably, a through slot is provided on the upper cover, and the gear is provided through the through slot.

[0014] Preferably, a temperature sensor is installed on the inner top of the upper cover.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The fan can discharge the heat between the upper cover and the lower cover, and the external air enters between the upper cover and the lower cover through the annular filter plate, so as to realize the air circulation at the LED lamp beads and dissipate the heat of the LED lamp beads; the annular filter plate can block the dust and flying insects in the air to prevent them from entering between the upper cover and the lower cover, so as not to affect the internal LED lamp beads.

[0017] 2. The rotation of the annular rack plate drives the sleeve and the annular filter plate to rotate. Due to the rotation of the annular filter plate, the flying insects cannot stably attach to the annular filter plate, which makes it less likely to cause blockage of the annular filter plate.

[0018] 3. Since the position of the fan is fixed, when the sleeve and the annular filter plate rotate, the relative position of the annular filter plate and the air outlet of the fan is constantly changing. The fan blows from the inside of the annular filter plate to the outside, achieving a backwashing effect on the annular filter plate, which can effectively remove dust and small flying insects on the annular filter plate, and avoid the annular filter plate from being blocked, affecting the heat dissipation of the LED lamp beads, without manual cleaning.

[0019] 4. The heat exchange oil and air in the piston cylinder can be transported to the refrigeration box. The heat exchange oil in the refrigeration box is transported to the hollow heat-conducting rubber plate through the delivery pipe due to pressure and gravity. In this way, the flow of heat exchange oil in the hollow heat-conducting rubber plate can be realized. The heat on the circuit board can be taken away through heat transfer, thereby effectively dissipating the heat of the circuit board to ensure its stable operation.

[0020] 5. The air can be transported to the serpentine exhaust pipe. Since the serpentine exhaust pipe is located in the heat exchange oil, when the air flows through the serpentine exhaust pipe, the temperature of the air can be reduced by heat exchange. Finally, the low-temperature air after heat exchange is discharged through the serpentine exhaust pipe. As shown in the figure, since the fan and the serpentine exhaust pipe are arranged relative to each other, the low-temperature air flows through the surface of the LED lamp beads, which can cool and dissipate the heat of the LED lamp beads.

[0021] To sum up, the present invention can effectively dissipate heat for LED lamp beads while filtering out dust and flying insects in the air to avoid affecting the LED lamp beads. At the same time, it can remove dust from the annular filter plate and drive away flying insects without manual participation in cleaning the annular filter plate, and can effectively and efficiently dissipate heat for circuit boards and LED lamp beads to ensure their stable operation.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figures 1-11 An LED lamp for industrial lighting includes a mounting plate 1, wherein the mounting plate 1 is penetrated by four mounting holes, and the mounting plate 1 can be mounted on the mounting panel by passing bolts through the mounting holes; four pull rods 2 are fixed to the bottom of the mounting plate 1, and an upper cover 12 is fixed to the bottom of the four pull rods 2, and a lower cover 14 is provided below the upper cover 12. The upper cover 12 and the lower cover 14 are fixed together by multiple connecting rods 15, and the outer part of the upper cover 12 and the lower cover 14 is provided with a sleeve 5 rotatably connected thereto. The upper cover 12 and the lower cover 14 are both circular and cylindrical, wherein the bottom of the lower cover 14 is a light-transmitting plate so that the LED lamp beads 19 can emit light and transmit light.

[0036] An annular filter plate 6 is installed on the sleeve 5 opposite to the connecting rod 15, and a bearing or other guide component can be installed on the upper cover 12 or the lower cover 14 to enable the sleeve 5 to rotate stably on the upper cover 12 and the lower cover 14; wherein, a dustproof net can be installed on the annular filter plate 6 to further improve the dustproof effect, and at the same time prevent flying insects from entering the upper cover 12 and the lower cover 14, so that it is not easy for flying insects and flying insect feces to fall on the light-transmitting plate, affecting the light transmittance.

[0037] A circuit board 18 is installed in the upper cover 12, and a plurality of LED lamp beads 19 are installed at the bottom of the circuit board 18. A fan 16 is fixed on the lower cover 14, and the fan 16 does not contact the sleeve 5; the air outlet end of the fan 16 is arranged opposite to the annular filter plate 6, and the inner wall of the sleeve 5 is provided with an annular groove 24, and an annular rack plate 13 is fixed in the annular groove 24. The motor 3 is installed on the upper cover 12, and a drive shaft 21 is fixed to the output end of the motor 3. A gear 22 is installed on the drive shaft 21, and the gear 22 is meshed with the annular rack plate 13. When the motor 3 works, it drives the drive shaft 21 to rotate, and the rotation of the drive shaft 21 drives the gear 22 to rotate. The rotation of the gear 22 drives the annular rack plate 13 to rotate, thereby realizing the rotation of the sleeve 5 and the annular filter plate 6 on the upper cover 12 and the lower cover 14; wherein, a through groove 33 is penetrated on the upper cover 12, and the gear 22 is set through the through groove 33.

[0038] The motor 3 drives the drive shaft 21 and the gear 22 to rotate, and the gear 22 rotates to drive the sleeve 5 and the annular filter plate 6 to rotate. When the annular filter plate 6 rotates, the position of the annular filter plate 6 and the air outlet end of the fan 16 continues to change. The fan 16 works by blowing from the inside to the annular filter plate 6 to back-blow and clean the annular filter plate 6; wherein, a temperature sensor 28 is installed on the inner top of the upper cover 12, and also includes a controller connected to the temperature sensor 28, and the controller is connected to the fan 16 and the motor 3; when the temperature sensor 28 detects that the temperature inside the upper cover 12 reaches the set value, the temperature sensor 28 transmits a signal to the controller, and the controller controls the motor 3 and the fan 16 to work, so as to dissipate heat to the LED lamp beads 19 and the circuit board 18.

[0039] The heat dissipation device further includes a heat dissipation mechanism for dissipating heat from the circuit board 18 and the LED lamp beads 19. The heat dissipation mechanism includes four connecting columns 20 fixed to the top of the upper cover 12. A hollow heat-conducting rubber plate 17 is fixed to the bottom of the four connecting columns 20. The circuit board 18 is embedded in the bottom of the hollow heat-conducting rubber plate 17. This allows for a larger contact area with the circuit board 18, which is beneficial for transferring heat from the circuit board 18 and dissipating heat from the circuit board 18. At the same time, the hollow heat-conducting rubber plate 17 has an insulating effect, preventing short circuits in electrical components on the circuit board 18.

[0040] A positioning plate 32 is fixed to the inner top of the upper cover 12, and a piston cylinder 23 is installed on the positioning plate 32. A movable piston 34 is slidably connected in the piston cylinder 23, and a connecting rod 25 is hingedly connected to the movable piston 34. The connecting rod 25 is eccentrically hinged to the bottom of the gear 22. A refrigeration box 4 is installed on the upper end of the upper cover 12, and heat exchange oil is installed in the refrigeration box 4. The reciprocating movement of the movable piston 34 can transport the heat exchange oil in the refrigeration box 4 to the hollow heat-conducting rubber plate 17 to exchange heat with the circuit board 18; a liquid inlet pipe 30 and a liquid outlet pipe 9 are installed on the piston cylinder 23, the liquid inlet pipe 30 is connected to the hollow heat-conducting rubber plate 17, and the liquid outlet pipe 9 is connected to the refrigeration box 4. A first one-way valve 31 is installed on the liquid inlet pipe 30, and the first one-way valve 31 only allows the heat exchange oil to enter the piston cylinder 23 through the liquid inlet pipe 30.

[0041] A second one-way valve 29 is installed on the liquid outlet pipe 9, and the hollow heat-conducting rubber plate 17 is connected to the refrigeration box 4 through the delivery pipe 8. The second one-way valve 29 only allows the hydraulic oil in the piston cylinder 23 to be delivered to the liquid outlet pipe 9; it also includes an air inlet pipe 26, which is connected to the piston cylinder 23. A third one-way valve 27 is installed on the air inlet pipe 26, and the third one-way valve 27 only allows air to enter the piston cylinder 23 through the air inlet pipe 26.

[0042] Among them, a semiconductor refrigeration plate 10 is installed through the refrigeration box 4, the cooling end of the semiconductor refrigeration plate 10 is located in the refrigeration box 4, and the heating end of the semiconductor refrigeration plate 10 is installed with a radiator 11, which can cool the heat exchange oil in the refrigeration box 4; wherein the controller controls the operation of the radiator 11 and the semiconductor refrigeration plate 10; a serpentine exhaust pipe 7 is installed on the refrigeration box 4, and the serpentine exhaust pipe 7 is partially located in the heat exchange oil. The lower end of the serpentine exhaust pipe 7 is arranged corresponding to the LED lamp bead 19, and the serpentine exhaust pipe 7 is located above the liquid level of the heat exchange oil. The upper end of the serpentine exhaust pipe 7 is located at one end of the refrigeration box 4 and is above the liquid level of the heat exchange oil. In this way, the air in the refrigeration box 4 can be discharged through the serpentine exhaust pipe 7.

[0043] When the present invention is used, the LED lamp beads 19 are powered on and work, and as the LED lamp beads 19 are used, the temperature between the upper cover 12 and the lower cover 14 increases, and the heat between the upper cover 12 and the lower cover 14 can be naturally dissipated through the annular filter plate 6;

[0044] As the temperature between the upper cover 12 and the lower cover 14 increases, when the temperature sensor 28 detects that the temperature is greater than the set value, the temperature sensor 28 transmits a signal to the controller, and the controller controls the motor 3, the fan 16 and the semiconductor cooling plate 10 to work;

[0045] The fan 16 can discharge the 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 circulation at the LED lamp beads 19 can be realized, and the LED lamp beads 19 can be cooled; the annular filter plate 6 can block dust and flying insects in the air and prevent them from entering between the upper cover 12 and the lower cover 14, so as not to affect the internal LED lamp beads 19;

[0046] The motor 3 drives the drive shaft 21 to rotate, and the rotation of the drive shaft 21 drives the gear 22 to rotate. The rotation of the gear 22 drives the annular rack plate 13 to rotate, and the rotation of the annular rack plate 13 drives the sleeve 5 and the annular filter plate 6 to rotate. Due to the rotation of the annular filter plate 6, flying insects cannot stably attach to the annular filter plate 6 (this part has a bright light to attract small flying insects), and thus it is not easy to cause the annular filter plate 6 to be blocked; since the position of the fan 16 is fixed, when the sleeve 5 and the annular filter plate 6 rotate, the relative position of the annular filter plate 6 and the air outlet end of the fan 16 is continuously changing, and the fan 16 works to blow outward from the inside of the annular filter plate 6, thereby achieving a backwashing effect on the annular filter plate 6, which can effectively remove dust on the annular filter plate 6 and small flying insects attached thereto, and can avoid the annular filter plate 6 from being blocked, affecting the heat dissipation of the LED lamp beads 19, and no manual cleaning is required;

[0047] The semiconductor refrigeration plate 10 can cool the heat exchange oil in the refrigeration box 4 when it works. The rotation of the gear 22 drives the connecting rod 25 to move, and the movement of the connecting rod 25 drives the movable piston 34 to move back and forth. When the movable piston 34 moves toward the direction of 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. At the same time, some air can be sucked into the piston cylinder 23 through the air inlet pipe 26. Therefore, there is heat exchange oil and air in the piston cylinder 23. When the movable piston 34 moves away from the motor 3, the heat exchange oil and air in the piston cylinder 23 can be transported to the refrigeration box 4. The heat exchange oil in the refrigeration box 4 is transported to the hollow heat-conducting rubber plate 17 through the delivery pipe 8 due to pressure and gravity. In this way, 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 by heat transfer, so that the circuit board 18 and the LED lamp beads 19 can be effectively dissipated to ensure its stable operation.

[0048] As the movable piston 34 reciprocates, the air in the refrigeration box 4 increases, resulting in an increase in the pressure in the refrigeration box 4. This not only squeezes the heat exchange oil, so that the heat exchange oil in the refrigeration box 4 is transported to the hollow heat-conducting rubber plate 17 through the delivery pipe 8, but also allows the air to be transported to the serpentine exhaust pipe 7. Since the serpentine exhaust pipe 7 is located in the heat exchange oil, when the air flows through the serpentine exhaust pipe 7, the temperature of the air can be reduced by heat exchange. Finally, the low-temperature air after heat exchange is discharged through the serpentine exhaust pipe 7. Figure 4As shown, since the fan 16 and the serpentine exhaust pipe 7 are arranged opposite to each other, the low-temperature air flows through the surface of the LED lamp beads 19, which can cool and dissipate the heat of the LED lamp beads 19 to ensure its stable operation.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
