Description

Technical Field

[0001] The present invention belongs to the technical field of LED lamps, and specifically relates to an LED lamp. Background Art

[0002] An LED lamp is a kind of lamp that uses a solid semiconductor chip as a light-emitting material. Its core component is a semiconductor wafer, which is composed of a P-type semiconductor and an N-type semiconductor. When a forward voltage is applied across both ends, electrons and holes recombine at the PN junction to release photons and generate light. It is applied in fields such as outdoor lighting, indoor lighting, special lighting, indicator lights / signaling lights, and LED displays.

[0003] In order to dissipate the internal heat energy, the lamp cover of a street lamp usually has certain gaps or ventilation openings to allow the heat to be discharged smoothly. Due to these gaps or ventilation openings, phototactic mosquitoes can enter, or under the action of natural wind, dust is brought into the interior of the lamp cover and accumulates. The dust and mosquitoes adhere to the surface of the lamp cover or the LED lamp beads, which not only blocks part of the light but may also cause faults such as short circuits or breakdowns in the circuit.

[0004] Therefore, the present invention provides an LED lamp. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: An LED lamp according to the present invention includes an enclosed lamp body provided on a lamp post;

[0007] A circulation pipeline is arranged inside the enclosed lamp body, and a transfer box is arranged inside the enclosed lamp body. One end of the circulation pipeline extends from the top of the transfer box to the inside, and the other end of the circulation pipeline is connected to the transfer box through a circulation component;

[0008] The circulation component includes a circulation pump, a first connecting pipe, and a second connecting pipe. The circulation pump is arranged on one side of the transfer box. One end of the first connecting pipe is connected to the output end of the circulation pump, and the other end of the first connecting pipe is connected to one end of the circulation pipeline. One end of the second connecting pipe extends from the bottom end of the transfer box to the inside, and the other end of the second connecting pipe is fixedly connected to the input end of the circulation pump.

[0009] A filter screen plate is arranged inside the transfer box. A cleaning block is slidably installed at the top end of the filter screen plate. Impurity inlet openings are formed on both sides of the bottom end of the cleaning block. A dust suction pipe is fixedly connected to the cleaning block, and the other end of the dust suction pipe is externally connected to a negative pressure device.

[0010] A blocking frame is fixedly installed inside the transfer box. A blocking partition is rotatably installed inside the blocking frame, and the blocking partition is arranged above the filter screen plate.

[0011] The filter screen plate is slidably installed inside the transfer box. Sliders are fixedly installed on the side walls of the filter screen plate. One end of the partition plate is fixedly installed with a second rotating rod. One end of the second rotating rod extends into the transfer box and is fixedly installed with a rotating gear. A toothed plate meshing with the rotating gear is elastically installed inside the transfer box. A connecting rope is fixedly connected between the toothed plate and the slider.

[0012] One end of the partition plate far from the second rotating rod is fixedly installed with a first rotating rod. A ratchet wheel is fixedly installed on the outer wall of the first rotating rod. A ratchet rod for blocking the rotation of the ratchet wheel is elastically installed inside the transfer box. A torsion spring is fixedly installed on the outer wall of the first rotating rod, and the other end of the torsion spring is fixedly connected to the inside of the transfer box.

[0013] A transmission rod is fixedly installed on the side wall of the ratchet rod. A push rod is slidably installed on the outer wall of the transmission rod. A spiral groove is formed on the outer wall of the transmission rod. A guide block is fixedly installed on the inner wall of the push rod, and one end of the guide block extends into the spiral groove.

[0014] A reciprocating lead screw is rotatably installed inside the transfer box. A transmission block is threadedly connected to the reciprocating lead screw. The transmission block is arranged below the filter screen plate. The top end of the transmission block and the bottom end of the cleaning block attract each other by magnetic force.

[0015] One end of the reciprocating lead screw is fixedly installed with a first bevel gear. A first connecting rod is rotatably installed inside the transfer box. A second bevel gear meshing with the first bevel gear is fixedly installed at the top end of the first connecting rod.

[0016] The bottom end of the first connecting rod extends into the second connecting pipe and is fixedly installed with a third bevel gear. A second connecting rod is rotatably installed inside the second connecting pipe. A fourth bevel gear meshing with the third bevel gear is fixedly installed at one end of the second connecting rod. Water turbine blades are fixedly installed on the outer wall of the second connecting rod.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the LED lamp described in the present invention, by starting the circulation pump, the water inside the transfer box can be sucked out through the second connecting pipe and conveyed into the circulation pipeline through the first connecting pipe. Under the pressure boost of the circulation pump, the water entering the circulation pipeline will automatically flow towards the inside of the transfer box, enabling the water to circulate inside the circulation pipeline. By combining the closed lamp body with water circulation for heat dissipation, it can not only effectively block the entry of dust and mosquitoes, but also ensure the heat dissipation effect inside the closed lamp body.

[0019] 2. The LED lamp of the present invention impacts the filter screen plate blocked by scale with water flow, causing the filter screen plate to move downward. The connecting rope pulls the toothed plate downward to drive the rotating gear to rotate, controls the blocking plate to fit with the blocking frame, blocks the water flow, and then controls the water flow to impact the water turbine blade through the circulation pump, so that the reciprocating lead screw always drives the transmission block to reciprocate. At this time, the transmission block and the cleaning block are magnetically attracted to reciprocate on the surface of the filter screen plate, and cooperate with the negative pressure device to extract the scale on the surface of the filter screen plate by negative pressure, ensuring the throughput of the filter screen plate while improving the stability of water circulation and heat dissipation.

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] As Figures 1 to 10 shown, an LED lamp according to an embodiment of the present invention includes a closed lamp body 2 provided on a lamp post 1;

[0034] A circulation pipeline 3 is provided inside the closed lamp body 2, a transfer box 4 is provided inside the closed lamp body 2, one end of the circulation pipeline 3 extends from the top of the transfer box 4 to the inside, and the other end of the circulation pipeline 3 is connected to the transfer box 4 through a circulation component;

[0035] The circulation pipeline 3 is arranged inside the closed lamp body 2 and is attached to the internal electronic components. By circulating water inside the circulation pipeline 3, the LED lamp beads inside the closed lamp body 2 can be dissipated heat. And through the provided closed lamp body 2, the entry of dust and mosquitoes can be effectively blocked. At the same time, by setting the water circulation heat dissipation method, the heat dissipation effect inside the closed lamp body 2 can be ensured.

[0036] A semiconductor refrigeration sheet can be provided inside the transfer box 4. When the water in the circulation pipeline 3 enters the transfer box 4, the water that takes away the heat of the LED lamp beads at this time can be cooled by the provided semiconductor refrigeration sheet.

[0037] The circulation component includes a circulation pump 5, a first connecting pipe 6 and a second connecting pipe 7. The circulation pump 5 is arranged on one side of the transfer box 4. One end of the first connecting pipe 6 is connected to the output end of the circulation pump 5, the other end of the first connecting pipe 6 is connected to one end of the circulation pipeline 3, one end of the second connecting pipe 7 extends from the bottom end of the transfer box 4 to the inside, and the other end of the second connecting pipe 7 is fixedly connected to the input end of the circulation pump 5.

[0038] One end of the circulation pipeline 3 is connected to the inside of the transfer tank 4, and the other end is connected to the first connecting pipe 6. The other end of the first connecting pipe 6 is connected to the output end of the circulation pump 5. The input end of the circulation pump 5 is communicated with the inside of the transfer tank 4 through the second connecting pipe 7.

[0039] When the circulation pump 5 is started, the water inside the transfer tank 4 can be sucked out through the second connecting pipe 7 and conveyed to the inside of the circulation pipeline 3 through the first connecting pipe 6. Under the boosting of the circulation pump 5, the water entering the circulation pipeline 3 will automatically flow towards the inside of the transfer tank 4.

[0040] As a preferred embodiment of the present invention, a filter screen plate 10 is provided inside the transfer tank 4. A cleaning block 14 is slidably installed at the top of the filter screen plate 10. Impurity inlet ports 15 are formed on both sides of the bottom end of the cleaning block 14. A suction impurity pipe 34 is fixedly connected to the cleaning block 14, and the other end of the suction impurity pipe 34 is externally connected to a negative pressure device.

[0041] Since the end of the circulation pipeline 3 flowing towards the transfer tank 4 extends downward from the top of the transfer tank 4 to the inside of the transfer tank 4, due to mineral ions such as calcium and magnesium contained in the water, they may crystallize and precipitate during the circulation process due to changes in conditions such as temperature and pressure, forming scale. Therefore, the water entering the transfer tank 4 will be filtered through the provided filter screen plate 10, which can effectively filter the scale. At the same time, a sliding cleaning block 14 is also provided on the filter screen plate 10. The cleaning block 14 fits on the surface of the filter screen plate 10. When the cleaning block 14 slides, the impurities on the surface of the filter screen plate 10 will be scraped into the inside of the cleaning block 14 through the impurity inlet ports 15 opened at the bottom. The scale entering the inside of the cleaning block 14 can be extracted through the negative pressure device and the suction impurity pipe 34, effectively ensuring the flow rate of the filter screen plate 10.

[0042] As a preferred embodiment of the present invention, a blocking frame 8 is fixedly installed inside the transfer tank 4. A blocking partition 9 is rotatably installed inside the blocking frame 8, and the blocking partition 9 is arranged above the filter screen plate 10.

[0043] The blocking partition 9 is arranged on the inner wall of the blocking frame 8. By controlling the rotation of the blocking partition 9 so that both ends of the blocking partition 9 are in contact with the outer wall of the blocking frame 8, the inner cavity of the transfer tank 4 can be divided into two parts. At this time, the water between the blocking partition 9 and the filter screen plate 10 will fall through the mesh holes to the bottom of the transfer tank 4 until there is no water between the filter screen plate 10 and the blocking partition 9. At this time, the cleaning block 14 can be controlled to slide, and the scale on the filter screen plate 10 can be removed in cooperation with the negative pressure device, ensuring the flow rate of the filter screen plate 10 while reducing the loss of circulating water.

[0044] As a preferred embodiment of the present invention, the filter screen plate 10 is slidably installed inside the transfer box 4. Sliders 13 are fixedly installed on the side walls of the filter screen plate 10. One end of the partition plate 9 is fixedly installed with a second rotating rod 29. One end of the second rotating rod 29 extends into the transfer box 4 and is fixedly installed with a rotating gear 32. An internally toothed plate 30 that meshes with the rotating gear 32 is elastically installed inside the transfer box 4. A connecting rope 31 is fixedly connected between the toothed plate 30 and the slider 13.

[0045] Sliders 13 are arranged on both sides of the filter screen plate 10. At the same time, sliding grooves for the sliders 13 to slide are also opened on the inner wall of the transfer box 4. The sliding track of the filter screen plate 10 can be limited through the cooperation of the sliding grooves and the sliders 13. The toothed plate 30 is slidably installed inside the transfer box 4 through a compression spring. The compression spring can always maintain a tendency to press the toothed plate 30. At this time, the rotating gear 32 will drive the second rotating rod 29 and the partition plate 9 not to fit with the blocking frame 8.

[0046] When there is a lot of scale on the filter screen plate 10 and all the mesh holes are blocked, at this time, the water flow rate gradually decreases until it cannot pass through. At this time, under the pressure boost of the circulation pump 5, the water flow will push the filter screen plate 10 to move downward. At this time, the toothed plate 30 will be simultaneously pulled downward through the connecting rope 31. The compression spring deforms and stores elastic potential energy. At the same time, the rotating gear 32 is driven to rotate, controlling the partition plate 9 to rotate and fit with the blocking frame 8 to block the water flow. At this time, there will be some accumulated water between the blocking frame 8 and the filter screen plate 10, and the filter screen plate 10 can be dredged through the sliding of the cleaning block 14.

[0047] As a preferred embodiment of the present invention, a first rotating rod 22 is fixedly installed at one end of the partition plate 9 away from the second rotating rod 29. A ratchet wheel 23 is fixedly installed on the outer wall of the first rotating rod 22. An internally ratchet bar 24 for blocking the rotation of the ratchet wheel 23 is elastically installed inside the transfer box 4. A coil spring 35 is fixedly installed on the outer wall of the first rotating rod 22. The other end of the coil spring 35 is fixedly connected to the inside of the transfer box 4.

[0048] The counterclockwise rotation of the first rotating rod 22 can be blocked through the provided ratchet wheel 23 and ratchet bar 24. Therefore, when the toothed plate 30 slides downward, driving the rotating gear 32 to rotate the partition plate 9, it will not be blocked by the ratchet bar 24. And when the partition plate 9 rotates, it will also drive the coil spring 35 to rotate through the first rotating rod 22. The ratchet bar 24 is installed inside the transfer box 4 through a torsion spring. Under the limitation of the ratchet bar 24, the coil spring 35 will maintain a deformed state until the ratchet bar 24 is rotated to release the block on the ratchet wheel 23, and the coil spring 35 will release elastic potential energy to drive the first rotating rod 22 to reset, so that the partition plate 9 moves away from the blocking frame 8 and the water continues to flow.

[0049] As a preferred embodiment of the present invention, a transmission rod 25 is fixedly installed on the side wall of the ratchet rod 24. A push rod 26 is slidably installed on the outer wall of the transmission rod 25. A spiral groove 27 is formed on the outer wall of the transmission rod 25. A guide block 28 is fixedly installed on the inner wall of the push rod 26. One end of the guide block 28 extends into the spiral groove 27.

[0050] The transmission rod 25 is located inside the transfer box 4. When the ratchet rod 24 blocks the ratchet wheel 23, at this time, the push rod 26 is located inside the transfer box 4 under the cooperation of the spiral groove 27 and the guide block 28. When the baffle plate 9 fits with the blocking frame 8 to block the water flow, at this time, the water flow will still continuously enter the inside of the transfer box 4. As the water pressure increases, it will push the push rod 26 to slide towards the transmission rod 25. Under the cooperation of the guide block 28 and the spiral groove 27, the transmission rod 25 can be driven to rotate, so that the ratchet rod 24 releases the block on the ratchet wheel 23, and the torsion spring 35 will drive the first rotating rod 22 to reset the baffle plate 9.

[0051] As a preferred embodiment of the present invention, a reciprocating lead screw 12 is rotatably installed inside the transfer box 4. A transmission block 11 is connected to the reciprocating lead screw 12 by a thread. The transmission block 11 is arranged below the filter mesh plate 10. The top end of the transmission block 11 and the bottom end of the cleaning block 14 attract each other by magnetic force.

[0052] When the filter mesh plate 10 is blocked, the impact of the water flow causes the filter mesh plate 10 to slide down until the filter mesh plate 10 slides to fit with the transmission block 11. At this time, by controlling the reciprocating lead screw 12 to slide, the transmission block 11 is driven to reciprocate at the bottom end of the filter mesh plate 10 until the transmission block 11 and the cleaning block 14 attract each other by magnetic force. At this time, when the transmission block 11 slides, the cleaning block 14 can be driven to slide synchronously.

[0053] As a preferred embodiment of the present invention, a first bevel gear 21 is fixedly installed at one end of the reciprocating lead screw 12. A first connecting rod 33 is rotatably installed inside the transfer box 4. A second bevel gear 20 meshing with the first bevel gear 21 is fixedly installed at the top end of the first connecting rod 33. The bottom end of the first connecting rod 33 extends into the second connecting pipe 7 and is fixedly installed with a third bevel gear 19. A second connecting rod 17 is rotatably installed inside the second connecting pipe 7. A fourth bevel gear 18 meshing with the third bevel gear 19 is fixedly installed at one end of the second connecting rod 17. A water wheel blade 16 is fixedly installed on the outer wall of the second connecting rod 17.

[0054] When the circulating pump 5 drives the second connecting pipe 7 to extract the circulating water in the transfer tank 4, the water flow will impact the water turbine blade 16, causing it to rotate. At the same time, the second connecting rod 17 will be driven to rotate, causing the fourth bevel gear 18 to drive the third bevel gear 19 to rotate. At this time, the first connecting rod 33 will drive the second bevel gear 20 to rotate, and finally drive the first bevel gear 21 to rotate, so that the reciprocating screw rod 12 always drives the transmission block 11 to slide reciprocally. When the filter screen plate 10 slides down, the transmission block 11 can cooperate with the cleaning block 14 at any time.

[0055] Working principle: When the circulating pump 5 is started, the water inside the transfer tank 4 can be sucked out through the second connecting pipe 7 and conveyed into the interior of the circulating pipeline 3 through the first connecting pipe 6. Under the boosting of the circulating pump 5, the water entering the circulating pipeline 3 will automatically flow towards the interior of the transfer tank 4, causing the water to circulate in the circulating pipeline 3. By combining the closed lamp body 2 with water circulation for heat dissipation, not only can dust and mosquitoes be effectively blocked from entering, but also the heat dissipation effect inside the closed lamp body 2 can be ensured.

[0056] The scale of the circulating water can be filtered through the provided filter screen plate 10. As the scale on the filter screen plate 10 increases and the throughput gradually decreases, the water flow will push the filter screen plate 10 downward, pull the toothed plate 30 downward through the connecting rope 31 to drive the rotating gear 32 to rotate, control the blocking plate 9 to fit with the blocking frame 8, block the water flow, and then control the water flow to impact the water turbine blade 16 through the circulating pump 5, drive the second connecting rod 17 to rotate, cause the fourth bevel gear 18 to drive the third bevel gear 19 to rotate. At this time, the first connecting rod 33 will drive the second bevel gear 20 to rotate, and finally drive the first bevel gear 21 to rotate, so that the reciprocating screw rod 12 always drives the transmission block 11 to slide reciprocally, making the transmission block 11 magnetically attracted to the cleaning block 14, slide reciprocally on the surface of the filter screen plate 10, and cooperate with the negative pressure device to perform negative pressure extraction on the scale on the surface of the filter screen plate 10, ensuring the throughput of the filter screen plate 10 while improving the stability of water circulation heat dissipation.
