Description

Technical Field

[0001] This invention relates to the field of lighting heat dissipation technology, specifically to a lighting heat sink and its LED energy-saving lamp. Background Technology

[0002] LED energy-saving lamps are a new generation of lighting source following compact fluorescent lamps (i.e., ordinary energy-saving lamps). LED energy-saving lamps are environmentally friendly, mercury-free, recyclable, low power consumption, high luminous efficiency, long lifespan, instant on / off, resistant to frequent switching, low light decay, rich colors, dimmable, and offer a variety of color variations.

[0003] When energy-saving lamps are in use, both the electronic control module and the lamp itself generate heat. Since these lamps need to be kept on for extended periods in public places, the continuous heat emitted significantly impacts their lifespan. Therefore, energy-saving lamps require heat dissipation during use. Current heat dissipation methods primarily involve heat sinks. However, if the airflow is incorrect or there is no airflow, the heat sinks cannot function effectively, resulting in poor heat dissipation and failing to adequately solve the heat dissipation problem of energy-saving lamps. Summary of the Invention

A fixed slider is slidably installed inside the fixed groove. A spring is connected between the fixed slider and the bottom of the inner wall of the fixed groove. A spherical block is installed on the side of the fixed slider away from the spring. A spherical groove is provided on the side of the mounting rod close to the spherical block. The spherical block can be snapped into the inside of the spherical groove.

[0008] Preferably, the cooling mechanism includes a cooling tank, the inside of the fixed cylinder is provided with a cooling tank, the inside of the cooling tank is filled with coolant, the fixed cylinder is made of thermally conductive alloy material, and the inside of the cooling tank is provided with a second auxiliary mechanism.

[0009] Preferably, the second auxiliary mechanism includes a third electric slider and a lever. A third groove is provided on the inner wall of the cooling tank along the circumferential direction of the cooling tank. The third electric slider is slidably installed inside the third groove. A lever is installed on the side of the third electric slider away from the third groove.

[0010] Preferably, the first auxiliary mechanism includes a first movable plate, a connector is installed at the bottom of the first electric slider, a rotating block is rotatably installed inside the connector, the first movable plate is movably installed at the bottom of the rotating block, a first rotary motor is installed on one side of the connector, the output end of the first rotary motor movably passes through the side wall of the connector, and the output end of the first rotary motor is connected to the rotating block.

[0011] Preferably, a second rotary motor is embedded at the end of the rotating block away from the first electric slider. The output end of the second rotary motor faces the first movable plate and is connected to the first movable plate. A cleaning mechanism is provided on one side of the first movable plate.

[0012] Preferably, the cleaning mechanism includes a brush and an electric telescopic rod. The electric telescopic rod is embedded in one end wall of the first movable plate. The telescopic end of the electric telescopic rod is away from the first movable plate, and the brush is installed at the telescopic end of the electric telescopic rod.

[0013] Preferably, the bottom of the first movable plate is provided with a second slot, and a second sliding groove is vertically provided on one side of the inner wall of the second slot. A second electric slider is slidably installed inside the second sliding groove. A second movable plate is movably installed inside the second slot. A third slot is provided on the side of the second movable plate near the second electric slider. A third rotary motor is installed at the bottom of the third slot. The output end of the third rotary motor is connected to the inner side wall of the third slot. A connecting rod is movably installed inside the third slot. The end of the connecting rod near the third rotary motor is connected to the third rotary motor. The end of the connecting rod near the second electric slider is connected to the second electric slider. The side of the second movable plate near the second electric slider is covered with sponge. A reflector is provided on the side of the second movable plate away from the second electric slider.

[0014] An LED energy-saving lamp includes the aforementioned lamp heat sink. The bottom of the fixed cylinder is detachably mounted with an energy-saving lamp body. The bottom of the mounting rod is connected to the top of the energy-saving lamp body. An electronic control module is snapped into the interior of a fourth slot, and the outer wall of the electronic control module abuts against the inner wall of the fourth slot. The top of the heat dissipation fins abuts against the bottom of the fixed cylinder.

[0015] The beneficial effects of this invention are reflected in:

[0016] In this invention, by setting a first movable plate and a cooling tank, the heat of the electronic control module is directly transferred to the fixed cylinder. The fixed cylinder can quickly absorb the heat emitted by the electronic control module through the coolant injected inside the cooling tank, thereby achieving the effect of cooling the electronic control module and extending its service life. The heat emitted by the energy-saving lamp body is transferred to the heat dissipation fins. The heat dissipation fins abut against the fixed cylinder, so the fixed cylinder can absorb the heat of the heat dissipation fins, enhancing the heat dissipation effect of the heat dissipation fins, and further enhancing the heat dissipation effect of the device.

[0017] The control system detects the wind direction around the usage location. The two first movable plates closest to the wind direction rotate under the drive of the second rotary motor, causing the two first movable plates to rotate into a "bowl shape". The larger opening side of the two first movable plates is away from the energy-saving lamp body, and the smaller opening side of the two first movable plates is close to the energy-saving lamp body. When the wind blows through the device, it will be guided by the first movable plates from the larger opening side to the smaller opening side, and then pass through the energy-saving lamp body. Through this air guiding method of the first movable plates, the wind can pass through the heat dissipation fins of the energy-saving lamp body faster, enhancing the heat dissipation efficiency of the energy-saving lamp body. Since the heat dissipation fins abut against the bottom of the fixed cylinder, it can also enhance the cooling effect of the coolant inside the fixed cylinder on the electronic control module.

[0018] In windy weather, multiple movable plates form a large windbreak. Through the guiding effect of multiple movable plates, the wind can pass through the gaps between the heat dissipation fins, making full use of natural wind power to achieve the best heat dissipation effect of the heat dissipation fins. At the same time, the method of fixing the air guide with movable plates can also achieve the effect of energy saving and emission reduction, and increase the environmental friendliness of the device.

[0019] When it rains, multiple first movable plates move to the direction of the oblique drift of the rainwater. At this time, the multiple first movable plates form a rain shield, which can protect the energy-saving lamp body from rainwater, prevent the energy-saving lamp body from getting wet, and increase the service life of the energy-saving lamp body.

[0020] In this invention, a second movable plate and a brush are provided. The brush rotates to face the energy-saving lamp body, and then the electric telescopic rod drives the brush to move closer to the energy-saving lamp body. When the brush touches the energy-saving lamp body, the first electric slider slides in the first groove, causing the first movable plate to move in a circle around the energy-saving lamp body. During the movement of the first movable plate, the brush can brush off the dust and debris attached to the outside of the energy-saving lamp body and the outside of the heat dissipation fins, ensuring the heat dissipation effect of the device.

[0021] The side of the second movable plate with the sponge installed faces the energy-saving lamp body. Then, the third rotary motor drives the second movable plate to rotate, causing the sponge on the second movable plate to move towards the energy-saving lamp body. When the sponge on the second movable plate comes into contact with the bottom of the energy-saving lamp body, the second movable plate can wipe the bottom of the energy-saving lamp body while the first movable plate is moving around the energy-saving lamp body in a circular motion, ensuring the lighting effect of the energy-saving lamp body.

[0022] When the device is used in foggy weather, the side of the second movable plate with the reflector is rotated to face the energy-saving lamp body. The second movable plate moves away from the energy-saving lamp body and stops rotating after moving to a preset angle. At this time, because multiple reflectors are installed on the second movable plates, the second movable plate has a light-focusing effect on the light of the energy-saving lamp body, reducing the impact of fog on the lighting effect of the energy-saving lamp body.

[0034] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0035] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0036] like Figures 1-9 As shown, a lamp heat sink includes a fixed cylinder 1, with mounting blocks 2 installed on both sides of the top of the fixed cylinder 1. A first slot 3 is formed through the top of each mounting block 2. A cooling mechanism is provided inside the fixed cylinder 1, and a first sliding groove 4 is formed at the bottom of the fixed cylinder 1. Multiple first electric sliders 5 are slidably installed inside the first sliding groove 4, and a first auxiliary mechanism is provided at the bottom of each first electric slider 5. The cooling mechanism achieves rapid heat dissipation for the energy-saving lamp body 7. The first auxiliary mechanism removes dust and debris from the outside of the energy-saving lamp body 7, ensuring normal heat dissipation. The first auxiliary mechanism also increases airflow at the energy-saving lamp body 7, enhancing the heat dissipation effect of the device.

[0037] As a technical optimization of the present invention, a fourth slot 24 is provided at the bottom of the fixing cylinder 1, and a fifth slot 25 is provided through one side of the fourth slot 24. Two mounting slots 26 are provided at the bottom of the fixing cylinder 1, and a snap-fit ​​mechanism is provided inside the mounting slot 26. A mounting rod 22 is inserted and installed inside the mounting slot 26. By inserting the mounting rod 22 into the mounting slot 26, the energy-saving lamp body 7 can be quickly disassembled and assembled, increasing the ease of use of the device. The electronic control module is installed inside the fourth slot 24, so that the heat of the electronic control module can be conducted away, increasing the cooling effect of the device. The fifth slot 25 can be used as a slot for wiring, so that the wiring is not exposed, increasing the aesthetics of the device. The heat generated by the wiring can also be quickly conducted away, extending the service life of the wiring.

[0038] As an optimized technical solution of the present invention, the snap-fit ​​mechanism includes a spring 29 and a spherical block 30. Fixing grooves 27 are horizontally formed on both sides above the mounting groove 26. A fixing slider 28 is slidably installed inside the fixing groove 27. A spring 29 connects the fixing slider 28 to the bottom of the inner wall of the fixing groove 27. A spherical block 30 is installed on the side of the fixing slider 28 away from the spring 29. A spherical groove 23 is formed on the side of the mounting rod 22 near the spherical block 30. The spherical block 30 can be snapped into the interior of the spherical groove 23. The mounting rod 22 presses against the spherical block 30, causing the fixing slider 28 to slide into the interior of the fixing groove 27 and compressing the spring 29. When the spherical groove 23 moves to the position of the spherical block 30, the fixing slider 28 slides under the rebound force of the spring 29, and the spherical block 30 snaps into the interior of the spherical groove 23, thus completing the installation of the energy-saving lamp body 7.

[0039] As a technical optimization of the present invention, the cooling mechanism includes a cooling tank 31. The cooling tank 31 is formed inside the fixed cylinder 1, and coolant is injected into the cooling tank 31. The fixed cylinder 1 is made of a thermally conductive alloy, and a second auxiliary mechanism is provided inside the cooling tank 31. By rapidly cooling the fixed cylinder 1 with coolant, the energy-saving lamp body 7 and the electronic control module are rapidly cooled.

[0040] As a technical optimization of the present invention, the second auxiliary mechanism includes a third electric slider 33 and a lever 34. A third groove 32 is formed on the inner wall of the cooling tank 31 along the circumferential direction of the cooling tank 31. The third electric slider 33 is slidably installed inside the third groove 32, and the lever 34 is installed on the side of the third electric slider 33 away from the third groove 32. By sliding the third electric slider 33 in the third groove 32, the lever 34 can move the coolant inside the cooling tank 31, making the coolant fluid and ensuring the cooling stability of the device.

[0041] As an optimized technical solution of the present invention, the first auxiliary mechanism includes a first movable plate 6, a connecting member 8 installed at the bottom of the first electric slider 5, a rotating block 9 rotatably installed inside the connecting member 8, the first movable plate 6 movably installed at the bottom of the rotating block 9, and a first rotary motor 10 installed on one side of the connecting member 8. The output end of the first rotary motor 10 movably passes through the side wall of the connecting member 8 and is connected to the rotating block 9. The first rotary motor 10 can adjust the operating angle of the first movable plate 6, allowing the first movable plate 6 to change its operating mode according to usage requirements, increasing the ease of use of the device.

[0042] As a technical optimization of the present invention, a second rotary motor 15 is embedded and installed at the end of the rotating block 9 away from the first electric slider 5. The output end of the second rotary motor 15 faces the first movable plate 6 and is connected to the first movable plate 6. A cleaning mechanism is provided on one side of the first movable plate 6. The second rotary motor 15 can drive the first movable plate 6 to rotate, allowing the first movable plate 6 to change its operation mode according to usage requirements, thus increasing the ease of use of the device.

[0043] As an optimized technical solution of the present invention, the cleaning mechanism includes a brush 11 and an electric telescopic rod 12. The electric telescopic rod 12 is embedded in one end wall of the first movable plate 6, and the telescopic end of the electric telescopic rod 12 is away from the first movable plate 6. The brush 11 is installed at the telescopic end of the electric telescopic rod 12. When the brush 11 abuts against the energy-saving lamp body 7, the first electric slider 5 slides in the first slide groove 4, causing the first movable plate 6 to move in a circular motion around the energy-saving lamp body 7. During the movement of the first movable plate 6, the brush 11 can brush off the dust and debris attached to the outside of the energy-saving lamp body 7 and the outside of the heat dissipation fins, ensuring the heat dissipation effect of the device.

[0044] As a technical optimization of the present invention, the bottom of the first movable plate 6 is provided with a second slot 13, and a second sliding groove 16 is vertically provided on one side of the inner wall of the second slot 13. A second electric slider 17 is slidably installed inside the second sliding groove 16. A second movable plate 14 is movably provided inside the second slot 13. A third slot 18 is provided on the side of the second movable plate 14 near the second electric slider 17. A third rotary motor 20 is installed at the bottom of the third slot 18. The output end of the third rotary motor 20 is connected to the inner side wall of the third slot 18. A connecting rod 19 is movably provided inside the third slot 18. One end of the connecting rod 19 near the third rotary motor 20 is connected to the third rotary motor 20. One end of the connecting rod 19 near the second electric slider 17 is connected to the second electric slider 17. The side of the second movable plate 14 near the second electric slider 17 is covered with sponge. A reflector is provided on the side of the second movable plate 14 away from the second electric slider 17. By sliding the second electric slider 17 in the second slide groove 16, the second movable plate 14 can freely enter and exit the interior of the second slot 13 according to the usage requirements, increasing the ease of use of the device. When the sponge on the second movable plate 14 abuts against the bottom of the energy-saving lamp body 7, the second movable plate 14 can wipe the bottom of the energy-saving lamp body 7 during the circular motion of the first movable plate 6 around the energy-saving lamp body 7, ensuring the lighting effect of the energy-saving lamp body 7. When the bottom end of the first movable plate 6 abuts against the outer side of the energy-saving lamp body 7, the third rotary motor 20 drives the second movable plate 14 to move away from the energy-saving lamp body 7, and stops rotating after moving to a preset angle. At this time, because reflectors are installed on multiple second movable plates 14, the second movable plates 14 have a focusing effect on the light of the energy-saving lamp body 7, reducing the impact of fog on the lighting effect of the energy-saving lamp body 7.

[0045] An LED energy-saving lamp includes the aforementioned lamp heat sink. The bottom of a fixing cylinder 1 is detachably mounted with an energy-saving lamp body 7. The bottom of a mounting rod 22 is connected to the top of the energy-saving lamp body 7. An electronic control module is snapped into the interior of a fourth slot 24, with the outer wall of the electronic control module abutting against the inner wall of the fourth slot 24. The top of the heat dissipation fins abuts against the bottom of the fixing cylinder 1. Using the LED energy-saving lamp with the lamp heat sink can achieve effective heat dissipation and extend the lifespan of the LED energy-saving lamp.

[0046] When in use, the electric drive mechanism used in this device is controlled by the preset control system on the device. This device can be used in conjunction with a wind direction detector. The wind direction detector detects the wind direction and wind force of the place of use, and then transmits the detection results to the control system on the device. The control system adjusts the various mechanisms on the device based on the detection results transmitted by the wind direction detector. The power cord is installed on the electric control module on the energy-saving lamp body 7.

[0047] When this device is used on a high-speed railway platform, workers install the fixing cylinder 1 on the top of the platform using fixing bolts that pass through the first slot 3. Alternatively, when used in other locations, it can also be installed at the desired location using fixing bolts. The power cord is passed through the fifth slot 25. The operator then connects the power cord on the energy-saving lamp body 7 to the power cord passing through the fifth slot 25. Next, the operator pushes the energy-saving lamp body 7 upwards, aligning the electronic control module with the fourth slot 24 and the mounting rod 22 with the mounting slot 26. During this upward push, the mounting rod 22 presses against the spherical block 30, causing the fixed slider 28 to slide into the fixed slot 27 and compressing the spring 29. When the spherical slot 23 reaches the spherical block 30, the fixed slider 28 slides under the rebound force of the spring 29, and the spherical block 30 engages with the inside of the spherical slot 23. This completes the installation of the energy-saving lamp body 7. With this installation method, when the energy-saving lamp body 7 needs to be replaced, the operator only needs to pull down the part of the energy-saving lamp body 7 to be replaced and then disconnect the power cord connection to complete the disassembly. This convenient and quick method increases the ease of use of the device.

[0048] During the use of the energy-saving lamp body 7, both the energy-saving lamp body 7 and the electronic control module will generate heat. At this time, the heat of the electronic control module will be directly transferred to the fixed cylinder 1. The fixed cylinder 1 can quickly absorb the heat emitted by the electronic control module through the coolant injected inside the cooling tank 31, thereby achieving the effect of cooling the electronic control module and extending its service life. The heat emitted by the energy-saving lamp body 7 will be transferred to the heat dissipation fins. The heat dissipation fins abut against the fixed cylinder 1, so the fixed cylinder 1 can absorb the heat of the heat dissipation fins, enhancing the heat dissipation effect of the heat dissipation fins and further enhancing the heat dissipation effect of the device. By sliding the third electric slider 33 in the third slide groove 32, the lever 34 can move the coolant inside the cooling tank 31, making the coolant fluid and ensuring the cooling stability of the device.

[0049] In hot weather, the control system detects the wind direction around the usage area. When the wind blows through the gaps in the heat sink fins, the two first movable plates 6 facing the wind direction rotate under the drive of the second rotary motor 15, causing them to rotate into a "bowl shape." The wider side of the two first movable plates 6 is away from the energy-saving lamp body 7, while the narrower side is closer to the energy-saving lamp body 7. When the wind blows through the device, it is guided by the first movable plates 6 and flows from the gaps in the heat sink fins. The air blows from the larger opening to the smaller opening, and then passes through the energy-saving lamp body 7. This air guiding method of the first movable plate 6 allows the air to pass through the heat dissipation fins of the energy-saving lamp body 7 faster, enhancing the heat dissipation efficiency of the energy-saving lamp body 7. During this process, the first movable plate 6, which is away from the airflow direction, rotates to a state where the end wall is tangent to the airflow direction under the drive of the second rotary motor 15, so as not to affect the speed at which the air flows out from the energy-saving lamp body 7. Furthermore, because the heat dissipation fins abut against the bottom of the fixed cylinder, the cooling effect of the coolant inside the fixed cylinder on the electronic control module is also enhanced.

[0050] In windy weather, due to the unpredictable wind direction, the wind cannot pass through the gaps in the heat dissipation fins, thus the heat dissipation effect of the heat dissipation fins cannot be fully utilized. At this time, the control system determines the wind direction based on the detection results of the wind direction detector. Then, the second rotary motor 15 drives the first movable plate 6 to rotate to a preset angle. Subsequently, the first electric slider 5 slides in the first slide groove 4, causing multiple first movable plates 6 to move to preset positions. At this time, multiple first movable plates 6 form a large wind deflector. Through the guiding effect of multiple first movable plates 6, the wind can pass through the gaps in the heat dissipation fins, making full use of natural wind power to achieve the best heat dissipation effect of the heat dissipation fins. At the same time, the fixed air guiding method of the first movable plates 6 can also achieve the effect of energy saving and emission reduction, increasing the environmental friendliness of the device.

[0051] When it rains, the rainwater, influenced by the wind, will drift at an angle. At this time, the energy-saving lamp body 7 located outdoors may get wet. The first rotating motor 10 drives the first movable plate 6 to rotate away from the energy-saving lamp body 7. When the rotation reaches a preset angle, the rotation stops. Then, the first electric slider 5 slides in the first slide groove 4, causing multiple first movable plates 6 to move in the direction of the rainwater drift. At this time, multiple first movable plates 6 form a rain shield, which can protect the energy-saving lamp body 7 from rainwater, prevent the energy-saving lamp body 7 from getting wet, and increase the service life of the energy-saving lamp body 7.

[0052] During use, dust and debris floating in the air adhere to the outer side of the energy-saving lamp body 7 and the heat dissipation fins, which seriously affects the heat dissipation of the device. At this time, the second rotary motor 15 drives the first movable plate 6 to rotate, so that the brush 11 rotates to face the energy-saving lamp body 7. Then, the electric telescopic rod 12 drives the brush 11 to move closer to the energy-saving lamp body 7. When the brush 11 touches the energy-saving lamp body 7, the first electric slider 5 slides in the first slide groove 4, so that the first movable plate 6 moves in a circle around the energy-saving lamp body 7. During the movement of the first movable plate 6, the brush 11 can brush off the dust and debris attached to the outer side of the energy-saving lamp body 7 and the outer side of the heat dissipation fins, ensuring the heat dissipation effect of the device.

[0053] If dust adheres to the lighting area of ​​the energy-saving lamp body 7, it will affect the lighting effect of the energy-saving lamp body 7. At this time, the second electric slider 17 slides in the second slide groove 16, causing the second movable plate 14 to move out of the second slot 13. When the second movable plate 14 moves out of the interior of the second slot 13, the side of the second movable plate 14 with the sponge installed faces the energy-saving lamp body 7. Then, the third rotary motor 20 drives the second movable plate 14 to rotate, causing the sponge on the second movable plate 14 to move towards the energy-saving lamp body 7. When the sponge on the second movable plate 14 comes into contact with the bottom of the energy-saving lamp body 7, the second movable plate 14 can wipe the bottom of the energy-saving lamp body 7 during the circular motion of the first movable plate 6 around the energy-saving lamp body 7, ensuring the lighting effect of the energy-saving lamp body 7.

[0054] When the device is used in foggy weather, the lighting effect of the energy-saving lamp body 7 is severely affected by the fog. At this time, the second movable plate 14 moves out of the interior of the second slot 13 and drives the first movable plate 6 to rotate through the second rotary motor 15. This causes the side of the second movable plate 14 with the reflector to rotate towards the energy-saving lamp body 7. Then, the first rotary motor 10 drives the first movable plate 6 to rotate closer to the energy-saving lamp body 7. When the bottom end of the first movable plate 6 abuts against the outside of the energy-saving lamp body 7, the third rotary motor 20 drives the second movable plate 14 to move away from the energy-saving lamp body 7. After moving to a preset angle, the rotation stops. At this time, because multiple second movable plates 14 are equipped with reflectors, the second movable plates 14 have a focusing effect on the light of the energy-saving lamp body 7, reducing the impact of fog on the lighting effect of the energy-saving lamp body 7.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
