Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and specifically to a segmented heat dissipation type LED street lamp. Background Art

[0002] With the acceleration of the urbanization process, road lighting plays a crucial role in traffic safety, night economy, and urban image shaping. Traditional street lamps mostly use light sources such as high-pressure sodium lamps, which have many disadvantages such as high energy consumption, low luminous efficiency, short lifespan, and high maintenance costs. In recent years, LED street lamps have gradually become the mainstream due to their significant advantages such as high luminous efficiency, low energy consumption, and long lifespan.

[0003] However, traditional LED street lamps usually have heat dissipation slots, which ventilate and dissipate heat inside the street lamp. However, when not in use, there is no hot air flowing out of the heat dissipation slots, and dust and particles will enter the inside of the street lamp, affecting the heat dissipation effect of the LED street lamp. Summary of the Invention

[0006] Preferably, the illumination component includes an LED lamp board, the outer wall of the LED lamp board is arranged inside the housing, a lamp cover is fixedly connected to the outer wall of the housing, and the outer wall of the lamp cover is slidably connected to the outer wall of the sponge pad.

[0007] Preferably, a support plate is fixedly connected inside the outer shell. A first fan is arranged around the upper surface of the support plate.

The second fan is electrically connected to the storage battery box, and the first electric push rod is electrically connected to the storage battery box.

[0008] Preferably, a second electric push rod is arranged inside the outer shell. The second electric push rod is electrically connected to the storage battery box.

[0009] Preferably, a limiting rod is fixedly connected to the output end of the second electric push rod. Fixed columns are slidably connected to both sides inside the limiting rod.

[0010] Preferably, the outer walls of the fixed columns are fixedly connected inside the outer shell, and limiting columns are fixedly connected to the upper surfaces of the fixed columns.

[0011] Preferably, bases are fixedly connected to both sides of the upper surface of the limiting rod. A rotating rod is rotatably connected inside the bases.

[0012] Preferably, a rotating plate is rotatably connected to the right side inside the rotating rod. A connecting block is rotatably connected to the outer wall of the rotating plate. The lower surface of the connecting block is fixedly connected inside the outer shell.

[0013] Preferably, a pressing rod is rotatably connected to the outer wall of the connecting block. A second fixed rod is rotatably connected inside the pressing rod. The second fixed rod is rotatably connected inside the rotating rod.

[0014] Preferably, the pressing rod is in contact with the LED light board.

[0015] Working principle: When the street lamp is powered on and in use, first, the power is transmitted from the power storage box to the inside of the LED lamp panel, making the LED lamp panel emit light. Then, the light is dispersed through the lampshade to illuminate the road surface. When the power storage box starts to transmit power, the electric push rod 1 is also activated. The electric push rod 1 pulls the cross bar to move. When the cross bar moves, it drives the two sliders on both sides to move simultaneously. The lower slide rail ensures that the moving direction and route of the sliders are fixed. When the sliders move, they drive the slide rail to move, and the slide rail movement drives the rotating column 1 to move synchronously, causing the connecting rod to rotate around the rotating column 1 as the center. When the connecting rod rotates, it makes the rotating column 2 and the limiting ring move downward, and then drives the sealing block to move downward horizontally. When the slider moves to a certain position, at this time, the sealing block disengages from the inside of the cushion block and moves backward to the rear of the housing, exposing the through groove, so that the wind on the outer wall can enter the inside of the housing through the through groove to cool the LED lamp panel and the power storage box. When it needs to be closed, when the slider is pushed to move to a certain position, first, the limiting ring will first touch the baffle, making the sealing block move vertically upward and not move forward with the movement of the slider. When the electric push rod 1 returns to its original position, at this time, the surface of the sealing block in contact with the outside world is at the same horizontal line as the surface of the housing in contact with the outside world, and this is a complete closure. When the street lamp needs to work, the sealing block is received inside the housing, allowing the wind to enter the inside of the housing to cool the LED lamp panel and the power storage box. When it does not need to work, the housing can be completely closed. Through cooperation with the lampshade, it can prevent dust from entering the inside of the housing, preventing dust and other particles from sticking to the outer walls of the LED lamp panel and the power storage box, affecting heat dissipation, and at the same time, it can extend the service life of the street lamp.

[0016] When the electric push rod 1 pulls the cross bar to move, it also drives the two fixed rods 1 on both sides to move backward. The movement of the fixed rod 1 drives the L-shaped rod to move. The movement of the L-shaped rod drives the sponge pad to move, so that the sponge pad wipes the surface of the LED lamp panel. One of the L-shaped rods on the left and right is at the front end of the lampshade, and the other is set at the middle position of the lampshade. After moving backward, the front L-shaped rod will move to the middle position, and the middle L-shaped rod will move to the tail position to wipe the lampshade. While not blocking the light source dispersed by the lampshade and opening the sealing block, it also cleans the lampshade. At the same time, when the fixed rod 1 moves, it also drives the blocking rod to move. When closing, the blocking rod can completely block the chute where the fixed rod 1 moves, achieving the effect of preventing dirt adhered to the lampshade due to rain or wind from affecting heat dissipation.

[0017] After the sealing block is completely opened, the power storage box transmits current to the inside of the fan 2 and the fan 1. The direction of the wind blown by the fan 2 is directly opposite to the through groove, which can effectively blow the hot air inside out of the housing. The support plate plays a supporting role for the fan 1, and the fan 1 dissipates heat from the power storage box, achieving effective segmented heat dissipation.

[0018] When the LED light board is damaged and needs to be replaced, the electric push rod two is started. The electric push rod two pulls the limit rod to move on the outer wall of the fixed column. The limit column prevents the limit rod from moving too much and causing the limit rod to disengage. When the limit rod moves, it will also drive the two base seats on both sides to move. When the base seat moves, it will pull the rotating rod downward. Since the connecting block is fixedly connected to the outer shell, relying on the lever principle, the rotating rod will turn upward, thereby driving the rotating plate to rotate. When the rotating rod turns, it will also drive the fixed rod two to move. The fixed rod two moves to pull the pressing rod to turn around the place where the pressing rod is connected to the connecting block. When the pressing rod turns, the fixed rod two will also rotate, so that the pressing rod no longer presses the LED light board, achieving the effect of facilitating the replacement of the LED light board.

[0019] That is, when the street lamp needs to work, the sealing block can be received inside the outer shell, so that the wind can enter the inside of the outer shell to cool the LED light board and the storage battery box. When it does not need to work, the outer shell can be completely closed. Through cooperation with the lampshade, it can prevent dust from entering the inside of the outer shell, so that dust and other particles adhere to the outer walls of the LED light board and the storage battery box, affecting heat dissipation. At the same time, it can also improve the service life of the street lamp. And when not blocking the light source emitted by the lampshade and opening the sealing block, it can also clean the lampshade to prevent dirt adhered to the lampshade due to rain or wind from affecting heat dissipation. It can also achieve the effect of facilitating the replacement of the LED light board.

[0020] The present invention provides a segmented heat dissipation type LED street lamp. It has the following beneficial effects:

[0021] 1. In the present invention, the electric push rod one is started by the power transmission of the storage battery box, pulling the cross bar to drive the slider to move, so that the rotating column one moves, and then the rotating column two and the limit ring move downward, driving the sealing block to move downward. When the slider moves to a specific position, the sealing block moves away from the cushion block, and the through groove of the outer shell is exposed for ventilation and cooling. And the two fixed rods one on both sides move backward accordingly, driving the L-shaped rod and the sponge pad to wipe the surface of the lampshade, avoiding the adhesion of dust and other particles on the outer walls of the LED light board and the storage battery box, affecting the heat dissipation effect, ensuring heat dissipation and extending the service life of the street lamp, and ensuring the normal heat dissipation function of the street lamp.

[0022] 2. In the present invention, by starting the electric push rod to pull the limit rod to move on the outer wall of the fixed column, and then driving the two base seats on both sides to move, the base seat pulls the rotating rod downward. Because the connecting block is fixedly connected to the outer shell, according to the lever principle, the rotating rod turns upward and drives the rotating plate to rotate. When the rotating rod turns, it also drives the fixed rod to move. The fixed rod pulls the pressing rod to turn around the connection point between itself and the connecting block, so that the pressing rod no longer presses the LED light board, facilitating the replacement of the LED light board.

[0023] 3. In the present invention, by starting the first electric push rod to drive the sealing block into the interior of the housing, and when the sealing block is being received into the interior, it will drive the sponge pad to wipe the lamp cover. By starting the second electric push rod to release the pressure rod from pressing on the LED lamp board, the maintenance difficulty is reduced, and the maintenance time and cost are decreased.

[0031] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0032] Please refer to the attached Figure 1 - attached Figure 4, an embodiment of the present invention provides a segmented heat dissipation type LED street lamp, including a housing 1. Inside the housing 1, an electric push rod 1 is fixedly connected. The output end of the electric push rod 1 is connected to a cross bar 3. On both sides of the outer wall of the cross bar 3, sliders 4 are fixedly connected. The outer wall of the slider 4 is slidably connected to a slide rail 5. The slide rail 5 is arranged inside the housing 1. Inside the slide rail 5, a rotating column 1 6 is fixedly connected. The outer wall of the rotating column 1 6 is rotatably connected to a connecting rod 7. Inside the connecting rod 7, a rotating column 2 8 is fixedly connected. The outer wall of the rotating column 2 8 is rotatably connected to a limiting ring 9. The outer wall of the limiting ring 9 is fixedly connected to a sealing block 10. In the middle of the outer wall of the cross bar 3, a fixing rod 1 12 is fixedly connected. On the outer wall of the fixing rod 1 12, an L-shaped rod 13 is fixedly connected. On the outer wall of the L-shaped rod 13, a sponge pad 14 is fixedly connected. On the outer wall of the fixing rod 1 12, a blocking rod 16 is fixedly connected. The outer wall of the blocking rod 16 is slidably connected to a cushion block 15. The outer wall of the cushion block 15 is fixedly connected inside the housing 1. The outer wall of the sealing block 10 is slidably connected to the inner wall of the cushion block 15. On the outer wall of the cushion block 15, a baffle 11 is arranged. The outer wall of the baffle 11 slides on the outer wall of the limiting ring 9. Inside the housing 1, a lighting component is arranged, and the lighting component is used to illuminate the road.

[0033] Specifically, when the street lamp is powered on and in use, the power storage box 21 transmits power to the LED lamp panel 17 to make it emit light. The lamp cover 18 diverges the light to illuminate the road surface. While the power storage box 21 transmits power, the electric push rod 1 is started, thereby pulling the cross bar 3 to move. The cross bar 3 drives the two side sliders 4 to move, thereby driving the rotating column 1 6 to move, making the connecting rod 7 rotate around the rotating column 1 6. The rotating column 2 8 and the limiting ring 9 move downward accordingly, driving the sealing block 10 to move downward. After the slider 4 moves to a certain position, the sealing block 10 disengages from the cushion block 15 and moves backward, and the through groove on the rear wall of the housing 1 is exposed. The outside air can enter the housing 1 to cool the LED lamp panel 17 and the power storage box 21. When it needs to be closed, the slider 4 is pushed to a certain position. The limiting ring 9 first touches the baffle 11 to make the sealing block 10 move upward. After the electric push rod 1 resets, the sealing block 10 is flush with the outer surface of the housing 1 to achieve complete closure. In this way, when the street lamp is working, the sealing block 10 is retracted into the housing 1 for ventilation and cooling. When it is not working, the housing 1 is completely closed, cooperating with the lamp cover 18 to prevent dust, avoiding dust and other particles from adhering to the outer walls of the LED lamp panel 17 and the power storage box 21, affecting the heat dissipation effect, ensuring heat dissipation, and prolonging the service life of the street lamp.

[0034] Please refer to the attached Figure 1 、attached Figure 3 and attached Figure 5 , the lighting component includes an LED lamp panel 17. The outer wall of the LED lamp panel 17 is arranged inside the housing 1. The outer wall of the housing 1 is fixedly connected with a lamp cover 18. The outer wall of the lamp cover 18 is slidably connected to the outer wall of the sponge pad 14.

[0035] Specifically, when the electric push rod 2 pulls the cross bar 3 to move, it will drive the two fixed rods 12 on both sides to move backward. The fixed rod 12 drives the L-shaped rod 13 to move, and the L-shaped rod 13 drives the sponge pad 14 to move, thereby wiping the surface of the lamp cover 18. Moreover, the movement of the fixed rod 12 will also drive the blocking rod 16 to move. When closed, the blocking rod 16 can completely block the chute where the fixed rod 12 moves, preventing dust and particles from entering the interior of the housing 1, so as to prevent the dirt adhered to the lamp cover 18 due to rain or wind from affecting heat dissipation.

[0036] Please refer to the attached Figure 1 and the attached Figure 3 , a support plate 19 is fixedly connected inside the housing 1. A first fan 20 is arranged around the upper surface of the support plate 19. A storage battery box 21 is fixedly connected inside the housing 1. The storage battery box 21 is electrically connected to the first fan 20. The storage battery box 21 is electrically connected to the LED lamp board 17. A second fan 22 is fixedly connected inside the housing 1. The second fan 22 is electrically connected to the storage battery box 21. The electric push rod 2 is electrically connected to the storage battery box 21.

[0037] Specifically, after the sealing block 10 is completely opened, the storage battery box 21 delivers current to the second fan 22 and the first fan 20. The wind blown by the second fan 22 is directly opposite to the through groove, and can efficiently blow the internal hot air out of the housing 1. The first fan 20 dissipates heat from the storage battery box 21, thereby realizing segmented heat dissipation.

[0038] Please refer to the attached Figure 1 , the attached Figure 3 and the attached Figure 6 , an electric push rod 23 is arranged inside the housing 1. The electric push rod 23 is electrically connected to the storage battery box 21. The output end of the electric push rod 23 is fixedly connected with a limiting rod 24. Both sides inside the limiting rod 24 are slidably connected with fixed columns 25. The outer wall of the fixed column 25 is fixedly connected inside the housing 1. The upper surface of the fixed column 25 is fixedly connected with a limiting column 26. Both sides of the upper surface of the limiting rod 24 are fixedly connected with bases 27. A rotating rod 28 is rotatably connected inside the base 27. The right side inside the rotating rod 28 is rotatably connected with a rotating plate 29. The outer wall of the rotating plate 29 is rotatably connected with a connecting block 30. The lower surface of the connecting block 30 is fixedly connected inside the housing 1. The outer wall of the connecting block 30 is rotatably connected with a pressing rod 31. The inside of the pressing rod 31 is rotatably connected with a second fixed rod 32. The inside of the second fixed rod 32 is rotatably connected inside the rotating rod 28. The pressing rod 31 is in contact with the LED lamp board 17.

[0039] Specifically, when the LED light board 17 needs to be replaced, the electric push rod two 23 is activated, thereby pulling the limiting rod 24 to move on the outer wall of the fixed column 25. The limiting column 26 prevents the limiting rod 24 from moving excessively and disengaging. When the limiting rod 24 moves, it drives the two bases 27 on both sides to move. The base 27 pulls down the rotating rod 28. Since the connecting block 30 is fixedly connected to the housing 1, according to the lever principle, the rotating rod 28 flips upward and drives the rotating plate 29 to rotate. When the rotating rod 28 flips, it also drives the fixed rod two 32 to move. The fixed rod two 32 pulls the pressing rod 31 to flip around the connection point between itself and the connecting block 30, and the fixed rod two 32 itself also rotates, so that the pressing rod 31 no longer presses the LED light board 17, facilitating the replacement of the LED light board 17.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
