[0048] like Figures 1 to 17As shown, an embodiment of the present invention provides an LED lamp that uses a water circulation structure to cool or heat up, including a lamp shell structure 1, the lamp shell structure 1 is used to protect the LED lamp to prevent the LED lamp from being damaged by rain or external force, the lamp shell structure 1 includes a first shell 11, one side of the first shell 11 is fixedly connected to the second shell 12, both ends of the second shell 12 are provided with cooling pipe clamping grooves 121, the second shell 12 is fixedly connected to the side away from the first shell 11 with a third shell 13, the first shell 11 is used to provide an installation space for the LED lamp sheet 4, the LED substrate 41, and the circulation structure 3, the second shell 12 is used to place the cooling pipe structure 2, and the third shell 13 is used to seal the second shell 12; an LED mounting hole is provided at the bottom of the first shell 11, the inner wall of the LED mounting hole is fixedly connected to the LED lamp sheet 4, and one side of the LED lamp sheet 4 is provided with an LED substrate 41, wherein the LED lamp sheet 4 and the LED substrate 41 are both prior art, and the bottom of the first shell 11 is fixedly connected to the two sides near the LED substrate 41 A water-isolating limit strip 112 is connected, and a shell drain port 111 is opened on the outer side of the first shell 11 near the water-isolating limit strip 112. The water-isolating limit strip 112 is used to isolate the water droplets dripping from the cooling tube structure 2 to prevent water from entering the LED substrate 41. The shell drain port 111 is used to drain the water droplets dripping from the cooling tube structure 2; the circulation structure 3 is located at the bottom of the first shell 11 and is connected. The circulation structure 3 is used to cool and heat the working LED substrate 41, and the LED substrate 41 that is in contact with it is cooled and heated by the circulation structure 3. The substrate 41 performs water circulation cooling and heating, which are respectively used when the external temperature is too high or too low. In the high temperature environment in summer, the LED lamp is cooled by the circulation structure 3 to ensure its normal operation and improve the lighting efficiency and life. In the low temperature environment such as cold storage, the LED lamp is heated by the circulation structure 3 to ensure the startup and normal use of the LED lamp; the cooling pipe structure 2 is located on the top of the circulation structure 3 and is connected to the cooling pipe structure 2. The cooling pipe structure 2 is used to assist the heat dissipation of the circulation structure 3, and the cooling effect of the circulation structure 3 is better.

[0049] During installation, the circulation structure 3 is installed at the bottom end of the first shell 11, and then the second shell 12 with the cooling tube structure 2 is installed on the first shell 11. While installing on the first shell 11, the cooling tube structure 2 is inserted into the circulation structure 3, and finally the third shell 13 is fixed on the top of the second shell 12. When the outside temperature is high, the LED substrate 41 is cooled by the water circulation inside the circulation structure 3, and the cooling tube structure 2 assists the circulation structure 3 in cooling by blowing. When the outside temperature is low, the circulation structure 3 heats the internal circulation medium, thereby heating the LED substrate 41 so that it can work normally.

[0050] like Figures 2 to 6As shown, the circulation structure 3 includes a water tank 31 fixedly connected to the bottom of the first shell 11. The water tank 31 is made of aluminum and has excellent thermal conductivity. An adapting groove 311 and a temperature rise and fall water groove 313 are respectively provided on both sides of the water tank 31. A contact groove 312 connected to the adapting groove 311 and the temperature rise and fall water groove 313 is provided between the adapting groove 311 and the temperature rise and fall water groove 313. The shape of the adapting groove 311 is consistent with the horizontal cross-sectional shape of the LED substrate 41, and the depth of the adapting groove 311 is slightly smaller than the thickness of the LED substrate 41. The outer surfaces of both ends of the water tank 31 are correspondingly fitted with the inner surface walls of the two water-isolating limit strips 112. When the water tank 31 is fixedly installed at the bottom of the first shell 11, the adapting groove 311 can be quickly inserted into the LED substrate 41. The heat generated on the D substrate 41 will be directly introduced into the water tank 31, and at the same time, the water-isolating limit strip 112 further limits the water tank 31. When installing the water tank 31, there is no need to worry about the problem of installation position deviation; the top of the water tank 31 is fixedly connected with a cover plate 32, and the cover plate 32 is used to seal the heating and cooling water tank 313 in the water tank 31 to prevent the circulating water inside the water tank 31 from flowing out. A circulating water pipe groove 321 is provided on the side of the cover plate 32 away from the water tank 31, and the circulating water pipe groove 321 is used to provide an installation space for the circulating water pipe 37; the bottom of the heating and cooling water tank 313 is connected with a cooling unit 38, and the cooling unit 38 is directly in contact with the LED substrate 41, and the temperature generated by the LED substrate 41 is preferentially transmitted to the cooling unit 38.

[0051] A temperature control device 36 is fixedly connected to the outer wall of one end of the water tank 31 away from the water outlet 314 of the water tank. A heating wire 361 is connected to the temperature control device 36. The heating wire 361 passes through one end of the water tank 31 and extends to the interior of the heating and cooling water tank 313. The heating wire 361 is an unclosed rectangle surrounding the top position of the cooling unit 38. The temperature control device 36 and the heating wire 361 are existing technologies. The internal temperature is detected by the temperature control device 36. When the temperature is too low, the temperature control device 36 controls the heating wire 361 to work and heat the circulating water inside the water tank 31 until it is heated to the set temperature. The circulating water temperature will be transmitted to the surface of the LED substrate 41 through the cooling unit 38 to heat it.

[0052] The invention also includes a circulation unit for realizing water circulation inside the water tank 31 and the cover plate 32. Two water pipe holes are vertically opened at one end of the water tank 31. The two water pipe holes are respectively fixedly connected with a water tank outlet 314 and a water tank inlet 315. The circulation unit includes a circulating water pump 33 fixedly connected to one end of the water tank 31. The outlet of the circulating water pump 33 is fixedly connected to the water tank inlet 315. A circulating water pipe 37 is arranged inside the circulating water pipe groove 321. The circulating water pipe 37 is used to export the circulating water inside the water tank 31 to the outside. First, the temperature difference between the circulating water pipe groove 321 and the inside of the water tank 31 is used to adjust the circulating water pipe. The circulating water inside 37 is cooled down. Secondly, the cooling pipe structure 2 guides the external flowing wind into the circulating water pipe groove 321 to further cool the circulating water pipe 37. Both ends of the circulating water pipe 37 penetrate the cover plate 32 and extend to the outside of the cover plate 32. The two ends of the circulating water pipe 37 are fixedly connected with the water inlet of the circulating water pump 33 and the water outlet 314 of the water tank respectively. The water inlet of the circulating water pump 33 draws the circulating water inside the water tank 31 through the circulating water pipe 37, and then discharges the circulating water from the water inlet 315 of the water tank into the water tank 31 through the water outlet. The internal circulating water is cooled down when passing through the circulating water pipe 37.

[0053] like Figures 6 to 10As shown, the cooling unit 38 includes a substrate cooling plate 381 fixedly connected to the inner surface wall of the contact groove 312, and the substrate cooling plate 381 and the inner surface wall of the contact groove 312 are sealed to prevent the circulating water inside the water tank 31 from entering the LED substrate 41 through the gap between the substrate cooling plate 381 and the contact groove 312. The substrate cooling plate 381 is provided with a water guide groove 382 at one end close to the water inlet 315 of the water tank, and the water guide groove 382 allows the internal circulating water to enter the interior of the substrate cooling plate 381. The substrate cooling plate 381 is in the circulation state. When the water is inside the water pipe, the contact area between the cooling plate 381 and the circulating water is increased, so that the temperature of the substrate cooling plate 381 is better transferred to the circulating water. At the same time, the water guide groove 382 provides an installation space for the guide block 386, and a plurality of heat sink grooves 385 connected to the water guide groove 382 are provided on one side of the cooling plate 381. The heat sink groove 385 is used to provide an installation space for the heat sink 384. The inner wall of the water guide groove 382 is fixedly connected to the corresponding position of the heat sink groove 385. The length of the guide group is less than the width of the water guide groove 382. Each guide block 386 is provided with a plurality of heat sink grooves 385 connected to the water guide groove 382. The group is composed of two mutually symmetrical guide blocks 386, and the guide group is used to guide the circulating water into the water guide groove 382. Through the guidance of the guide group, the circulating water forms several independent water cycles inside the water guide groove 382, ​​and the heat on the substrate cooling plate 381 is taken away more efficiently. One side of the several guide blocks 386 is fixedly connected with a heat sink 384. The substrate cooling plate 381 and the heat sink 384 are both made of aluminum. The heat sink 384 passes through the heat sink groove 385 and extends to the top of the substrate cooling plate 381. The guide block 386 consists of two guide sections 3 861 is connected with a fixed section 3862, and the two guide sections 3861 are fixedly connected to the two ends of the fixed section 3862 respectively. The guide block 386 has an S-shaped structure, and the upper surface cross-section of the guide block 386 is smaller than the lower surface cross-section. Therefore, a slope will be generated on the surface of the guide block 386, which can guide the circulating water passing through its surface. A drainage port that gradually narrows from wide is formed between the two symmetrical guide blocks 386, and at the same time, a drainage channel to both sides of the water guide trough 382 is formed between the guide blocks 386 between every two adjacent guide groups.

[0054] Since the water guide groove 382 is opposite to the water tank inlet 315, when the circulating water enters the water tank 31 from the water tank inlet 315 through the circulating water pump 33, an impact force will be generated, driving the circulating water at the notch of the water guide groove 382 to flow inward along the surface of the outermost guide group. The flowing circulating water enters from the drainage port between the two guide blocks 386, and then enters the next drainage port. When entering the next drainage port, it will push the circulating water that was originally stationary inside it, causing it to be divided into three streams of water. The three streams of water flow to the two adjacent drainage channels and the next drainage port respectively, and then the above process is repeated between several groups of guide groups. The circulating water passing through the drainage channel will flow to both sides of the water guide groove 382 under the guidance of the drainage channel, and flow out of the notch of the water guide groove 382 along both sides of the water guide groove 382, ​​thereby forming several small cycles inside it, which will take away the heat on the substrate cooling plate 381.

[0055] like Figure 2 , Fig.14 , Fig.15 and Fig.17As shown, the cooling pipe structure 2 includes two air duct units 22 fixedly connected to the inner wall of the cooling pipe slot 121, and a cooling port 211 is opened on one side of the straight pipe 21 close to the cover plate 32.

The first deflection section 2222 is fixedly connected to the first deflection section 2222, and one end of the first deflection section 2222 is fixedly connected to the first wind-inducing section 2221. The curved surface of the water-inducing section 2223 can block the rain and snow blown in by the outside wind, so as to prevent the rain and snow from entering the circulating water pipe groove 321 with the wind in rainy and snowy weather, and forming the problem of water accumulation for a long time. One end of the water-inducing section 2223 is fixedly connected to the first deflection section 2222, and one end of the first deflection section 2222 is fixedly connected to the first wind-inducing section 2221 with the outward shape.The second air guide piece 223 is formed by connecting the second air inducing section 2231, the third deflecting section 2232, the fourth deflecting section 2233 and the guide section 2234.

The guide section 2234 and the fourth deflecting section 2233 are integrally formed into a herringbone structure. The fourth deflecting section 2233 is close to the guide section. A plurality of second drainage ports 2236 are provided on one side of the segment 2234. The rain and snow blocked by the water-blocking segment 2223 will flow along the surface of the water-blocking segment 2223 to the fourth deflection segment 2233, and be discharged through the second drainage ports 2236 on the fourth deflection segment 2233, and then be discharged through the first drainage ports 2235.

The outside wind flows toward the fourth deflection section 2233 through the guide of the water-blocking section 2223, and is blown toward the air guide section 2225 under the guidance of the curved surface of the fourth deflection section 2233. Since the air guide section 2225 is a concave structure, the outside wind is guided again on the surface of the air guide section 2225, moves toward the cooling port 211, and enters into the circulating water pipe groove 321 through the cooling port 211, and cools the circulating water pipe 37 by blowing air.

[0057] like Figure 4 , Figures 11 to 14As shown, the fixing unit includes two first cards 34 fixedly connected to both sides of the cover plate 32, and the two first cards 34 cooperate to snap into the top of the straight tube 21, so as to clamp and limit the straight tube 21, and the top of the first card 34 is clamped with a second card 35, and the two sides of the second card 35 are clamped into the two ends of the first card 34, so as to limit the two first cards 34 to prevent the straight tube 21 from being separated from the clamping of the first card 34 when shaking. The first card 34 is composed of a connecting section 343, a first deformation section 344, a first limiting section 342, and an extrusion section 345 connected in sequence, and the bottom end of the connecting section 343 is fixedly connected to the outer wall of the cover plate 32, and the side of the connecting section 343 away from the cover plate 32 is turned inward. The first deformable section 344 is fixedly connected to the first limiting section 342 with a concave shape on one side of the first deformable section 344 away from the connecting section 343, and the first limiting section 342 is fixedly connected to the extrusion section 345 with an outward-turned shape on one side of the first deformable section 344. Two limiting blocks 341 are fixedly connected to the outer surface of the extrusion section 345, and the spacing between the two limiting blocks 341 is consistent with the length of the second card 35. When the straight tube 21 is fixed, the straight tube 21 is pressed, and the two sides of the straight tube 21 contact the extrusion section 345, so that the extrusion section 345 is subjected to the outward extrusion force of the two sides of the straight tube 21. At this time, the first deformable section 344 will be deformed, so that the extrusion section 345 is offset outward, so that the entire straight tube 21 The bottom of the tube 21 is inserted between the two connecting sections 343, squeezing and pressing the straight tube 21 until the bottom of the straight tube 21 fits with the top of the cover plate 32. At this time, after the squeezing section 345 has no squeezing force from the straight tube 21, the first deformation section 344 drives the squeezing section 345 to return to the initial position, and the first deformation section 344 and the first limiting section 342 cooperate to limit the top of the straight tube 21; the second card 35 is composed of a second limiting section 351, two second deformation sections 352 and two clamping sections 353. The second limiting section 351 is fixedly connected to the second deformation section 352 on both sides, and the second deformation section 352 is fixedly connected to the clamping section 353 at one end away from the second limiting section 351. 2 is an outward convex structure, and the second deformation section 352 is provided with a weakened groove on the inner side close to the second limiting section 351, and the clamping section 353 is an inwardly turned structure. When installing the second card 35, the clamping sections 353 on both sides of the second card 35 are aligned with the outer side of the extrusion section 345, and then the second card 35 is pressed. After the second card 35 is pressed, the second deformation section 352 is deformed, and the clamping section 353 is turned outward along the surface of the extrusion section 345 until the clamping section 353 is clamped into the two sides of the extrusion section 345, so that the second card 35 is limited and fixed on the first card 34, and the limiting block 341 limits the two sides of the second card 35 to prevent the second card 35 from sliding on the first card 34.

[0058] like Fig.15 and Fig.16As shown, the cooling port 211 is connected to two symmetrically distributed dustproof installation units 5, and the two dustproof installation units 5 are fixedly connected to dustproof cloths 6; the dustproof installation unit 5 is composed of two mutually hinged connecting blocks 51, and the ends of the two connecting blocks 51 away from the hinges are mutually clamped, and the connecting blocks 51 are prior art, one of which is fixedly connected to the two ends of the cooling port 211, and a card strip limiting groove 512 is provided at the end of the connecting block 51 away from the hinge, and one side of the card strip limiting groove 512 An embedding groove 511 is opened, and dust-proof cloth clips 61 compatible with the embedding groove 511 and the clip limit groove 512 are fixedly connected on both sides of the dust-proof cloth 6. When installing the dust-proof cloth 6, the dust-proof cloth clips 61 at both ends of the dust-proof cloth 6 are inserted into the embedding groove 511 and the clip limit groove 512, and then the two connecting blocks 51 are clamped and fixed, so as to fix the dust-proof cloth 6. The dust-proof cloth 6 can effectively isolate dust in the air and prevent dust in the air from sticking to the surface of the circulating water pipe 37, thereby reducing its cooling effect.

[0059] The working principle of the technical solution provided by the present invention is as follows: during installation, the circulation structure 3 is installed at the bottom end inside the first shell 11, the water tank 31 is fixedly installed at the bottom of the first shell 11, the adapter groove 311 is inserted into the LED substrate 41, and at the same time, the two sides of the water tank 31 are located between the two water-blocking limit strips 112, and then the second shell 12 with the cooling pipe structure 2 is installed on the first shell 11. While being installed on the first shell 11, the straight pipe 21 on the cooling pipe structure 2 is inserted into the circulation structure 3. When the straight pipe 21 is inserted, the straight pipe 21 is pressed, and the two sides of the straight pipe 21 contact with the extrusion section 345, so that the extrusion section 345 is subjected to the outward extrusion force from both sides of the straight pipe 21. At this time, the first deformation section 344 will be deformed, so that the extrusion section 345 is offset outward, so that the bottom of the entire straight pipe 21 is inserted between the two connecting sections 343, squeezing and pressing the straight pipe 21 until the straight pipe 2 The bottom of the cover plate 32 is fitted with the top of the cover plate 32. At this time, after the extrusion section 345 has no extrusion force from the straight tube 21, the first deformation section 344 drives the extrusion section 345 to return to the initial position. The first deformation section 344 and the first limiting section 342 cooperate to limit the top of the straight tube 21, and then the second card 35 is installed, and the clamping sections 353 on both sides of the second card 35 are aligned with the outer side of the extrusion section 345, and then the second card 35 is pressed. After the second card 35 is subjected to the pressing force, the second deformation section 352 is deformed, and the clamping sections 353 are turned outward along the surface of the extrusion section 345 until the clamping sections 353 are clamped into the two sides of the extrusion section 345, so that the second card 35 is limited and fixed on the first card 34. At the same time, the limiting block 341 will limit the two sides of the second card 35 to prevent the second card 35 from sliding on the first card 34, and finally fix the third shell 13 on the top of the second shell 12.

[0060] When the outside temperature is high, the LED substrate 41 is cooled by the water circulation inside the circulation structure 3. When the circulating water enters the water tank 31 from the water tank inlet 315 through the circulating water pump 33, an impact force is generated, driving the circulating water in the notch of the water guide groove 382 to flow inward along the surface of the outermost guide group. The flowing circulating water enters from the drainage port between the two guide blocks 386, and then enters the next drainage port. When entering the next drainage port, the original stationary circulating water in it will be pushed up, so that it will be divided into three streams. The three streams flow to the two adjacent drainage channels and the next drainage port respectively, and then the above process is repeated between several groups of guide groups. The circulating water passing through the drainage channel will flow to both sides of the water guide groove 382 under the guidance of the drainage channel, and flow out of the notch of the water guide groove 382 along both sides of the water guide groove 382, ​​so that several small cycles are formed inside it to take away the heat on the substrate cooling plate 381.

[0061] At the same time, the outside wind enters the air duct unit 22 from the outward-turned opening between the first air inlet section 2221 and the second air inlet section 2231, and the outside wind contacts the guide section 2234 first, and is guided by the curved surface of the guide section 2234 to the curved surface of the water-blocking section 2223. The outside wind flows toward the fourth deflection section 2233 through the guide of the water-blocking section 2223, and is blown toward the air guide section 2225 under the guidance of the curved surface of the fourth deflection section 2233. Since the air guide section 2225 is a concave structure, the outside wind is guided again on the surface of the air guide section 2225, moves toward the cooling port 211, and enters the circulating water pipe groove 321 through the cooling port 211, blowing air to cool the circulating water pipe 37.

[0062] When the outside temperature is low, the circulation structure 3 heats the internal circulating medium and detects the internal temperature through the temperature control device 36. When the temperature is too low, the temperature control device 36 controls the heating wire 361 to work and heat the circulating water inside the water tank 31 until it is heated to the set temperature. The circulating water temperature will be transmitted to the surface of the LED substrate 41 through the cooling unit 38 to heat it so that it can work normally.
