They typically have multiple functions such as explosion-proof, corrosion-proof, and waterproof, and can ensure the normal operation of the lighting system under harsh environmental conditions.

[0003] For example, invention patent application number CN202111620378.8 discloses an explosion-proof lamp, which includes a lamp head, a driving device, and an antenna. The lamp head includes a lamp head housing and a light source element disposed within the lamp head housing.

[0004] Existing explosion-proof lights still have the following shortcomings in actual use: for example, during use, because the internal space of the explosion-proof light is in a closed state, the air inside the light is difficult to circulate, making it difficult to dissipate the heat generated by the light body in a timely manner.

[0005] To address these issues, this invention proposes a modular LED explosion-proof light. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular LED explosion-proof light.

[0007] To achieve the above objectives, the technical solution adopted by this invention is: a modular LED explosion-proof light, comprising: The explosion-proof lamp housing has several heat dissipation fins fixedly connected in a ring array on its outer side wall, and a light source plate and a water-cooling plate located directly above the light source plate are installed inside. The bottom surface of the water-cooled plate is in contact with the top surface of the light source plate, and a water-cooling channel is provided inside the water-cooled plate. The water-cooling channel has an outlet and an inlet located on the same side. The inlet and outlet pipes are connected to the inlet and outlet of the water-cooling channel, respectively, and are connected to the water pump circuit. Several lamp bodies are distributed along the water-cooling channel at the bottom of the light source board, and water-cooling grooves are opened in the water-cooling channel at the positions corresponding to the lamp bodies to increase the heat dissipation area. Specifically, in the existing technology, during the use of explosion-proof lamps, because the internal space of the explosion-proof lamp is in a closed state, the air inside the explosion-proof lamp is difficult to circulate, which makes it difficult to dissipate the temperature generated by the lamp body in time. This technical solution can solve the above problems. The specific operation is as follows: when the explosion-proof lamp is started, the water pump starts, so that the cold water in the external condenser box enters the water cooling channel through the water inlet pipe, and then is discharged into the condenser box through the drain pipe. As cold water circulates within the water-cooling channel, it lowers the temperature of the water-cooling plate. The water-cooling plate then dissipates heat from the light source board, thereby reducing the temperature of the light source board and consequently lowering the internal temperature of the explosion-proof lamp housing. Since the lamp body is set on the light source board along the water-cooling channel, the water-cooling plate can cool the lamp body position, i.e. the heat source position, in a timely manner. In addition, water-cooling grooves are opened in the water-cooling channel corresponding to the lamp body position to increase the heat dissipation area, thereby ensuring that the heat source position can be sufficiently cooled, ensuring that the temperature of the light source board is effectively controlled, and preventing abnormal rise in the internal temperature of the explosion-proof lamp housing.

[0008] Preferred options also include: A temperature sensor is installed inside the explosion-proof lamp housing to detect the temperature inside the explosion-proof lamp housing; The controller controls the impeller speed inside the water pump based on the temperature signal from the temperature sensor, thereby adjusting the circulation speed of the cold water in the water-cooling channel.

[0009] Specifically, by setting a temperature sensor and controller, when the circuit output current increases to improve the brightness of the lamp body, the internal temperature of the explosion-proof lamp housing will rise. Based on the temperature signal from the temperature sensor, when the temperature value exceeds a specified threshold, the controller controls the impeller speed in the water pump to increase, thereby increasing the circulation speed of cold water in the water cooling channel, accelerating the cooling speed of the water cooling plate, so that the temperature of the light source board can be quickly carried away, ensuring that the temperature of the light source board is effectively controlled and preventing abnormal rise in the internal temperature of the explosion-proof lamp housing. When the temperature is below a specified threshold, the controller reduces the speed of the impeller in the water pump, thereby reducing energy consumption.

[0010] Preferred options also include: A ring-shaped water pipe is fixedly connected to several heat dissipation fins along the path. One end of the ring-shaped water pipe is connected to the end of the water outlet pipe, and the other end is connected to the water pump. Several sealed bearings are rotatably connected in a ring array inside an annular water pipe. One end of each sealed bearing is equipped with a turbine for driving the sealed bearing, and the other end passes through the annular water pipe and is fixedly connected to a fan. The fan is located between two heat dissipation fins.

[0011] Preferred options also include: Several receiving tubes are fixedly connected to the outer wall of the annular water pipe at the positions corresponding to the turbine. The turbine is slidably inserted into the groove opened at the end of the sealed bearing. A spring is fixedly connected between the turbine and the sealed bearing. The actuator, based on the temperature signal from the temperature sensor, activates the actuator when the temperature exceeds a specified threshold, driving several turbines from the receiving pipe into the annular water pipe.

[0012] Preferably, the actuating component includes: An annular explosion-proof enclosure is fixedly connected to the outer wall of an annular water pipe, and the receiving pipe is located inside the annular explosion-proof enclosure; Several magnets are fixedly connected to the end of the turbine; Several electromagnets are fixedly connected inside an annular explosion-proof housing, with the positions of the several electromagnets corresponding to the first electromagnet. Based on the temperature signal from the temperature sensor, when the temperature exceeds a specified threshold, the controller switches on the current to several electromagnets, causing the electromagnets to generate the same magnetic force as the magnets, thereby driving several turbines from the receiving pipe into the annular water pipe.

[0013] Preferably, each of the heat dissipation fins has two cleaning plates symmetrically slidably connected to both sides, and a brush is fixedly connected to the side wall of the cleaning plate; The reciprocating linear drive component is activated by the controller based on the temperature signal from the temperature sensor. When the temperature exceeds a specified threshold, the controller activates the reciprocating linear drive component, causing the cleaning plate to move back and forth along the side wall of the heat sink fins and clean the dust on the surface of the heat sink fins with a brush.

[0014] Preferably, the reciprocating linear drive assembly includes: A drive roller is sleeved on the outer wall of a sealed bearing and fixedly connected to the sealed bearing. A drive groove is formed on the surface of the drive roller. An annular sleeve is slidably connected to the surface of the drive roller. A sliding pin is fixed inside the annular sleeve and slidably connected to the drive groove. Telescopic frames are symmetrically fixed to both ends of the annular sleeve, and the cleaning plate is rotatably connected to the end of the telescopic frame.

[0015] Preferred options also include: The power supply housing is fixed to the top of the explosion-proof lamp housing, and a controller is installed inside it. The explosion-proof lamp housing has a first connecting groove and a second connecting groove at the top and bottom of the power supply housing, respectively, and the top of the water-cooled plate has a corresponding clearance groove for the power supply line to pass through.

[0016] Preferably, the drive groove is composed of first to fourth arc-shaped grooves connected end to end, used to guide the periodic reciprocating motion of the annular sleeve.

[0017] Preferably, the bottom end of the water-cooled plate is fixedly connected with several limiting rods of different diameters, and the top end of the light source plate has a slot for the limiting rod corresponding to the target position.

[0018] Compared with the prior art, the present invention has the following beneficial effects: I. This invention, by setting up a water-cooled plate, a water-cooled channel, and a water-cooled tank, ensures that the lamp body is set on the light source board along the trajectory of the water-cooled channel. The water-cooled plate can cool the lamp body position, i.e. the heat source position, in a timely manner. Furthermore, a water-cooled tank is opened in the water-cooled channel at the position corresponding to the lamp body to increase the heat dissipation area, thereby ensuring that the heat source position can be sufficiently cooled, ensuring that the temperature of the light source board is effectively controlled, and preventing abnormal temperature rise inside the explosion-proof lamp housing.

[0019] Second, this invention sets up a temperature sensor and a controller. Based on the temperature signal from the temperature sensor, when the temperature value exceeds a specified threshold, the controller controls the impeller speed in the water pump to increase, thereby increasing the circulation speed of cold water in the water cooling channel, accelerating the cooling speed of the water cooling plate, so that the temperature of the light source plate can be quickly carried away, ensuring that the temperature of the light source plate is effectively controlled and preventing abnormal temperature rise inside the explosion-proof lamp housing.

[0020] Third, this invention, by setting up an annular water pipe and a fan, when the temperature exceeds a specified threshold, the controller controls the impeller speed to increase, thereby increasing the circulation speed of the cold water in the water-cooling channel. At the same time, the electromagnet current is activated, causing the electromagnet to generate the same magnetic force as the magnet. Under the repulsion of like poles, the turbine slides along the surface of the sealed bearing and enters the annular water pipe. The water flow drives the turbine to rotate, which in turn causes the sealed bearing to drive the fan blades to rotate, thereby increasing the airflow between the heat dissipation fins and further reducing the temperature of the explosion-proof lamp housing, thus effectively controlling the internal temperature of the explosion-proof lamp housing.

[0021] IV. By setting up a cleaning plate and a reciprocating linear drive assembly, the drive roller rotates synchronously during the rotation of the sealed bearing. Under the guidance of the drive groove, the sealing sleeve moves back and forth along the drive groove. With the connection of the telescopic frame, the cleaning plate moves back and forth along the side wall of the heat dissipation fins. The dust on the surface of the heat dissipation fins is cleaned by the brush, ensuring that the heat dissipation fins can fully contact the air and improve the heat dissipation effect of the explosion-proof lamp housing.

Detailed Implementation

[0024] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] like Figures 1 to 8 The modular LED explosion-proof light shown includes: The explosion-proof lamp housing 1 has several heat dissipation fins 2 fixedly connected in a ring array on its outer side wall, and a light source plate 4 and a water-cooling plate 5 located directly above the light source plate 4 inside. The bottom surface of the water-cooled plate 5 is in contact with the top surface of the light source plate 4, and a water-cooling channel 501 is provided inside the water-cooled plate 5. The water-cooling channel 501 has an outlet and an inlet located on the same side. The inlet pipe 6 and outlet pipe 7 are respectively connected to the inlet and outlet of the water cooling channel 501 and are connected to the water circuit of the water pump 8. Several lamp bodies 401 are distributed along the trajectory of the water cooling channel 501 at the bottom of the light source board 4, and water cooling grooves 502 are opened in the water cooling channel 501 corresponding to the positions of the lamp bodies 401 to increase the heat dissipation area. Specifically, in the prior art, during the use of explosion-proof lamps, because the internal space of the explosion-proof lamp is in a closed state, the air inside the explosion-proof lamp is difficult to circulate, which makes it difficult to dissipate the temperature generated by the lamp body 401 in a timely manner. This technical solution can solve the above problems. The specific operation is as follows: when the explosion-proof lamp is started, the water pump 8 starts, so that the cold water in the external condensation box enters the water cooling channel 501 through the water inlet pipe 6, and then is discharged into the condensation box through the drain pipe. During the circulation of cold water in the water-cooling channel 501, the temperature of the water-cooling plate 5 will be reduced. The water-cooling plate 5 will dissipate heat from the light source plate 4, thereby reducing the temperature of the light source plate 4 and thus reducing the internal temperature of the explosion-proof lamp housing 1. Since the lamp body 401 is set on the light source plate 4 along the trajectory of the water cooling channel 501, the water cooling plate 5 can cool down the position of the lamp body 401, i.e. the heat source position, in a timely manner. In addition, a water cooling groove 502 is opened in the water cooling channel 501 corresponding to the position of the lamp body 401 to increase the heat dissipation area, thereby ensuring that the heat source position can be sufficiently cooled, ensuring that the temperature of the light source plate 4 is effectively controlled, and preventing the abnormal rise of the internal temperature of the explosion-proof lamp housing 1.

[0026] As a further embodiment of the present invention, it also includes: Temperature sensor 9 is installed inside the explosion-proof lamp housing 1 and is used to detect the temperature inside the explosion-proof lamp housing 1. The controller 10 controls the impeller speed of the water pump 8 based on the temperature signal from the temperature sensor 9, so as to regulate the circulation speed of the cold water in the water cooling channel 501. Specifically, by setting temperature sensor 9 and controller 10, when the circuit output current increases and the brightness of lamp body 401 is increased, the internal temperature of explosion-proof lamp housing 1 will rise. Based on the temperature signal of temperature sensor 9, when the temperature value exceeds the specified threshold, controller 10 controls the impeller speed in water pump 8 to increase, thereby increasing the circulation speed of cold water in water cooling channel 501, accelerating the cooling speed of water cooling plate 5, so that the temperature of light source plate 4 can be quickly carried away, ensuring that the temperature of light source plate 4 is effectively controlled and preventing abnormal rise in internal temperature of explosion-proof lamp housing 1; When the temperature value is less than the specified threshold, the controller 10 controls the impeller speed in the water pump 8 to slow down, thereby reducing energy consumption.

[0027] As a further embodiment of the present invention, an annular water pipe 11 is fixedly connected to several heat dissipation fins 2 on the path, one end of the annular water pipe 11 is connected to the end of the water outlet pipe 7, and the other end is connected to the water pump 8. Several sealed bearings 13 are rotatably connected in a ring array inside a ring water pipe 11. One end of each sealed bearing 13 is provided with a turbine 15 for driving the sealed bearing 13, and the other end passes through the ring water pipe 11 and is fixedly connected to a fan 14. The fan 14 is located between two heat dissipation fins 2. Several storage tubes 12 are fixedly connected to the outer wall of the annular water pipe 11 at the position corresponding to the turbine 15. The turbine 15 is slidably inserted into the groove opened at the end of the sealed bearing 13. A spring 17 is fixedly connected between the turbine 15 and the sealed bearing 13. The actuator, controller 10, is activated based on the temperature signal from temperature sensor 9. When the temperature exceeds a specified threshold, controller 10 activates the actuator to drive several turbines 15 from the receiving pipe 12 into the annular water pipe 11. The driving components include: The annular explosion-proof housing 18 is fixedly connected to the outer wall of the annular water pipe 11, and the receiving pipe 12 is located inside the annular explosion-proof housing 18. Several magnets 16 are fixedly connected to the ends of the turbine 15. Several electromagnets 19 are fixedly connected inside the annular explosion-proof housing, corresponding to the position of the first electromagnet 19. Based on the temperature signal from the temperature sensor 9, when the temperature exceeds a specified threshold, the controller 10 turns on the current of several electromagnets 19, causing the electromagnets 19 to generate the same magnetic force as the magnet 16, thereby driving several turbines 15 from the receiving pipe 12 into the annular water pipe 11. Specifically, by setting up annular water pipe 11 and fan 14, when the temperature exceeds a specified threshold, controller 10 controls the impeller speed to increase, thereby increasing the circulation speed of cold water in water cooling channel 501. At the same time, it activates the current of electromagnet 19, causing electromagnet 19 to generate the same magnetic force as magnet 16. Under the repulsion of like poles, turbine 15 slides along the surface of sealed bearing 13 and enters annular water pipe 11. The water flow drives turbine 15 to rotate, thereby causing sealed bearing 13 to drive fan blades to rotate, thereby increasing airflow between heat dissipation fins 2, further reducing the temperature of explosion-proof lamp housing 1, and effectively controlling the internal temperature of explosion-proof lamp housing 1. When the temperature is below the specified threshold, the controller 10 controls the impeller speed to slow down while disconnecting the current to the electromagnet 19, causing the electromagnet 19 to lose its magnetic force. Under the action of the spring 17, the turbine 15 enters the receiving pipe 12, reducing the space occupied by the annular water pipe 11, thereby ensuring the stability of the cold water circulation speed.

[0028] As a further embodiment of the present invention, two cleaning plates 20 are symmetrically and slidably connected to both sides of each heat dissipation fin 2, and a brush 21 is fixedly connected to the side wall of the cleaning plate 20. The reciprocating linear drive assembly, the controller 10, based on the temperature signal of the temperature sensor 9, when the temperature exceeds a specified threshold, the controller 10 starts the reciprocating linear drive assembly, so that the cleaning plate 20 moves back and forth along the side wall of the heat sink 2, and cleans the dust on the surface of the heat sink 2 by the brush 21. The reciprocating linear drive component includes: A drive roller 22 is sleeved on the outer wall of the sealed bearing 13 and fixedly connected to the sealed bearing 13. A drive groove 23 is provided on the surface of the drive roller 22. The annular sleeve 24 is slidably connected to the surface of the drive roller 22. A sliding pin is fixed inside the annular sleeve 24 and is slidably connected to the drive groove 23. Telescopic frames 25 are symmetrically fixed at both ends of the annular sleeve 24. The cleaning plate 20 is rotatably connected to the end of the telescopic frame 25. When the drive roller 22 rotates, the annular sleeve 24, guided by the drive groove 23, causes the cleaning plate 20 to reciprocate along the side wall of the heat dissipation fin 2, and the dust on the surface of the heat dissipation fin 2 is cleaned by the brush 21. The drive groove 23 includes a first arc-shaped groove 2301, a second arc-shaped groove 2302, a third arc-shaped groove 2303, and a fourth arc-shaped groove 2304. The end of the first arc-shaped groove 2301 is connected to the end of the second arc-shaped groove 2302, the beginning of the second arc-shaped groove 2302 is connected to the beginning of the third arc-shaped groove 2303, the end of the third arc-shaped groove 2303 is connected to the end of the fourth arc-shaped groove 2304, and the beginning of the fourth arc-shaped groove 2304 is connected to the beginning of the first arc-shaped groove 2301. Specifically, by setting up a cleaning plate 20 and a reciprocating linear drive assembly, the drive roller 22 rotates synchronously during the rotation of the sealed bearing 13. Under the guidance of the drive groove 23, the sealing sleeve moves back and forth along the drive groove 23. With the connection of the telescopic frame 25, the cleaning plate 20 moves back and forth along the side wall of the heat dissipation fin 2. The dust on the surface of the heat dissipation fin 2 is cleaned by the brush 21, ensuring that the heat dissipation fin 2 can fully contact the air and improve the heat dissipation effect on the explosion-proof lamp housing 1. Meanwhile, during the cleaning process of the heat sink fins 2, the generated dust will be blown away by the fan 14, keeping the dust away from the explosion-proof lamp housing 1 and preventing the dust from falling back and adhering to the heat sink fins 2.

[0029] It should be noted that: grooves are provided on both sides of the heat dissipation fins 2, and the cleaning plate 20 slides in the grooves; Several track seats are fixed on the outer wall of the explosion-proof lamp housing 1, and the annular sleeve 24 is slidably connected to the track seats.

[0030] As a further embodiment of the present invention, several limiting rods 503 of different diameters are fixedly connected to the bottom end of the water-cooled plate 5, and the limiting rods 503 at the top of the light source plate 4 corresponding to the target position are provided with slots 402. Specifically, by setting the limit rod 503 and the slot 402, it is ensured that several lamp bodies 401 are in contact with the water cooling tank 502 at the target position.

[0031] As a further embodiment of the present invention, it also includes: The power supply housing 3 is fixedly connected to the top of the explosion-proof lamp housing 1. The controller 10 is located inside the power supply housing 3. The top of the explosion-proof lamp housing 1 is provided with a first connecting groove 101, and the bottom of the power supply housing 3 is provided with a second connecting groove 301 corresponding to the position of the connecting groove. A clearance groove 504 is provided at the top of the water-cooled plate 5 corresponding to the position of the first connecting groove 101; Specifically, by setting the clearance slot 504, the wires inside the power supply housing 3 can be connected to the light source board 4 through the clearance slot 504.

[0032] Working principle of the invention: When the explosion-proof light is activated, the water pump 8 is activated, so that the cold water in the external condenser box enters the water cooling channel 501 through the water inlet pipe 6, and then is discharged into the condenser box through the drain pipe; During the circulation of cold water in the water-cooling channel 501, the temperature of the water-cooling plate 5 will be reduced. The water-cooling plate 5 will dissipate heat from the light source plate 4, thereby reducing the temperature of the light source plate 4 and thus reducing the internal temperature of the explosion-proof lamp housing 1. Since the lamp body 401 is set on the light source plate 4 along the trajectory of the water cooling channel 501, the water cooling plate 5 can cool down the position of the lamp body 401, i.e. the heat source position, in a timely manner. In addition, a water cooling groove 502 is opened in the water cooling channel 501 corresponding to the position of the lamp body 401 to increase the heat dissipation area, thereby ensuring that the heat source position can be sufficiently cooled, ensuring that the temperature of the light source plate 4 is effectively controlled, and preventing the abnormal rise of the internal temperature of the explosion-proof lamp housing 1. When the temperature exceeds the specified threshold, the controller 10 controls the impeller speed in the water pump 8 to increase, thereby increasing the circulation speed of the cold water in the water cooling channel 501, accelerating the cooling speed of the water cooling plate 5, so that the temperature of the light source plate 4 can be quickly carried away, ensuring that the temperature of the light source plate 4 is effectively controlled, and preventing the abnormal rise of the internal temperature of the explosion-proof lamp housing 1. When the temperature value is less than the specified threshold, the controller 10 controls the impeller speed in the water pump 8 to slow down, thereby reducing energy consumption.
