[0010] In at least some embodiments, the protective component includes: a protective bottom cover and an air duct; the protective bottom cover is slidably installed inside the connecting top cover, and the protective bottom cover is also in close contact with a rubber anti-slip sleeve; the bottom of the protective bottom cover has a ring of air inlet slots, and the protective bottom cover also has a ring of exhaust holes A; the air duct is provided in a ring, and the ring of air ducts is fixedly installed at the bottom of the protective bottom cover, and the ring of air inlet slots is located inside the ring of air ducts.

[0011] In at least some embodiments, the connecting component includes: a rectangular plate and a movable connecting bracket; the rectangular plate is fixedly mounted on the protective bottom cover, and the rectangular plate has an exhaust hole B, which is aligned with the exhaust hole A; the movable connecting bracket is slidably mounted on the rectangular plate, and the movable connecting bracket is also inserted into a limiting slot.

[0012] In at least some embodiments, the connecting assembly further includes: an adjusting screw and a helical spring; the adjusting screw is inserted into the movable connecting bracket and is also threadedly connected to the protective bottom cover; the helical spring is sleeved outside the adjusting screw and is located between the protective bottom cover and the movable connecting bracket.

[0013] In at least some embodiments, the lighting assembly includes: a first LED light and a second LED light; the first LED light is installed inside the protective bottom cover and is concentrically arranged with the protective bottom cover; the second LED light is installed on the first LED light.

[0014] In at least some embodiments, the lighting assembly further includes: mounting screws and a hexagonal block; there are two mounting screws, which are inserted into the first LED and the second LED, and are also threadedly connected to the protective bottom cover; the hexagonal block is fixedly mounted on the first LED, and the outer end of the hexagonal block is chamfered, and the hexagonal block is also inserted into the second LED.

[0015] In at least some embodiments, the lighting assembly further includes: circular conductive rods and support screws; there are four circular conductive rods, which are respectively fixedly installed on the first LED lamp and the second LED lamp, and two circular conductive rods on the first LED lamp are in contact with two rectangular conductive plates; there are four support screws, which are respectively threaded onto the first LED lamp and the second LED lamp, and the inner ends of the four support screws are in contact with the protective bottom cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the temperature sensor detects that the temperature in the connection between the top cover and the protective bottom cover exceeds the preset temperature value, the temperature sensor transmits the detected temperature information to the controller. At this time, the controller controls the output shaft of the micro motor to reciprocate at a certain angle. When the controller controls the output shaft of the micro motor to reciprocate, the two corresponding circular conductive rods will not separate from the two rectangular conductive pieces, ensuring that the first LED and the second LED are always in a powered state.

[0018] Furthermore, when the output shaft of the micro motor reciprocates, the protective bottom cover reciprocates under the action of the circular drive wheel and the rubber anti-slip sleeve. When the protective bottom cover rotates counterclockwise, external air enters the connecting top cover and the protective bottom cover through the corresponding two air inlet slots under the action of two air ducts. The air in the connecting top cover and the protective bottom cover is discharged through a ring of exhaust holes A. When the protective bottom cover rotates clockwise, external air enters the connecting top cover and the protective bottom cover through the corresponding two air inlet slots under the action of the other two air ducts. The air in the connecting top cover and the protective bottom cover is discharged through a ring of exhaust holes A. This increases the airflow speed in the connecting top cover and the protective bottom cover, which is beneficial for the heat dissipation in the connecting top cover and the protective bottom cover.

[0019] 2. The movable connecting frame of the present invention has a limiting effect on the protective bottom cover, preventing the protective bottom cover from falling off the connecting top cover. At the same time, the movable connecting frame and the limiting slot also limit the rotation angle of the protective bottom cover, ensuring that when the movable connecting frame rotates to the other side of the limiting slot, the other two circular conductive rods just contact the two rectangular conductive pieces.

[0020] In addition, when the protective bottom cover needs to be separated from the connecting top cover, the operator uses a screwdriver to turn the adjusting screw, which moves the movable connecting bracket inward, facilitating the separation of the movable connecting bracket from the limiting slot. When the protective bottom cover needs to be connected to the connecting top cover, the operator uses a screwdriver to turn the adjusting screw in the opposite direction, which moves the movable connecting bracket outward, facilitating the connection of the movable connecting bracket with the limiting slot.

[0021] 3. The hexagonal block design of this invention facilitates accurate connection between the first and second LED lights, and allows for easy insertion of two mounting screws into both lights. When the first LED light is damaged, the operator can activate the micro motor. When the micro motor operates, the protective cover changes angle, causing the two circular conductive rods on the second LED light to contact the two rectangular conductive plates. When both the first and second LED lights are damaged, the operator can replace them simultaneously, doubling the lifespan of each replacement and reducing maintenance frequency. Meanwhile, the user can continue to use the lights, ensuring normal lighting performance.

[0022] Furthermore, when the two circular conductive rods on the first LED light have poor contact with the two rectangular conductive pieces, the operator can use a screwdriver to turn the two support screws on the first LED light; when the two circular conductive rods on the second LED light have poor contact with the two rectangular conductive pieces, the operator can use a screwdriver to turn the two support screws on the second LED light; when the operator turns all four support screws with a screwdriver, the first and second LED lights can bend slightly, causing a slight change in the height of the four circular conductive rods, which helps to improve the contact effect between the two rectangular conductive pieces and the corresponding two circular conductive rods.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0042] Example: Please refer to Figures 1 to 9 As shown: This invention provides an LED lighting device that reduces maintenance frequency, comprising: a fixing component 100, a multi-functional component 200, a protective component 300, a connecting component 400, and a lighting component 500; the protective component 300 is installed inside the fixing component 100; the multi-functional component 200 is installed on the fixing component 100 and is used to rotate the protective component 300; the connecting component 400 has a ring, and the ring of connecting components 400 is installed on the protective component 300, and the ring of connecting components 400 is used to connect the protective component 300 to the fixing component 100; the lighting component 500 is installed inside the protective component 300.

[0043] In this embodiment of the disclosure, such as Figure 2 , Figure 4 and Figure 5 As shown, the fixing assembly 100 includes: a connecting top cover 101, rectangular conductive sheets 102, and connecting screws 103; the top of the connecting top cover 101 has two wire insertion holes 1011, and the outer wall of the connecting top cover 101 also has a ring of limiting slots 1012, and the number of limiting slots 1012 is the same as the number of connecting assemblies 400; there are two rectangular conductive sheets 102, and the two rectangular conductive sheets 102 are fixedly installed on the connecting top cover 101, and the two rectangular conductive sheets 102 are concentrically arranged with the two wire insertion holes 1011; there is a ring of connecting screws 103, and the ring of connecting screws 103 is inserted into the connecting top cover 101;

[0044] The multi-functional component 200 includes: a controller 201, a temperature sensor 202, and a micro motor 203; the controller 201 is fixedly mounted on the connecting top cover 101; the temperature sensor 202 is fixedly mounted on the connecting top cover 101 and is also electrically connected to the controller 201; the micro motor 203 is fixedly mounted on the connecting top cover 101 and is also electrically connected to the controller 201; the multi-functional component 200 also includes: a circular drive wheel 204 and a rubber anti-slip sleeve 205; the circular drive wheel 204 is fixedly mounted on the output shaft of the micro motor 203; the rubber anti-slip sleeve 205 is fixedly mounted on the outside of the circular drive wheel 204;

[0045] The protective component 300 includes: a protective bottom cover 301 and an air duct 302; the protective bottom cover 301 is slidably installed inside the connecting top cover 101, and the protective bottom cover 301 is also in close contact with the rubber anti-slip sleeve 205; a ring of air inlet slots 3011 is provided at the bottom of the protective bottom cover 301, and a ring of exhaust holes A3012 is also provided on the protective bottom cover 301; the air duct 302 is provided in a ring, and the ring of air duct 302 is fixedly installed at the bottom of the protective bottom cover 301, and the ring of air inlet slots 3011 is located inside the ring of air duct 302;

[0046] Its specific function is as follows: Since the temperature sensor 202 is fixedly installed on the connecting top cover 101 and is also electrically connected to the controller 201, when the temperature sensor 202 detects that the temperature in the connecting top cover 101 and the protective bottom cover 301 exceeds the preset temperature value, the temperature sensor 202 transmits the detected temperature information to the controller 201; at this time, the controller 201 controls the output shaft of the micro motor 203 to reciprocate and rotate a certain angle. When the controller 201 controls the output shaft of the micro motor 203 to reciprocate and rotate, the corresponding two circular conductive rods 505 will not separate from the two rectangular conductive pieces 102, ensuring that the first LED light 501 and the second LED light 502 are always in a powered state.

[0047] Furthermore, since the circular drive wheel 204 is fixedly mounted on the output shaft of the micro motor 203, and the rubber anti-slip sleeve 205 is fixedly mounted on the outside of the circular drive wheel 204, and the protective bottom cover 301 is in close contact with the rubber anti-slip sleeve 205, when the output shaft of the micro motor 203 reciprocates, the protective bottom cover 301 reciprocates under the action of the circular drive wheel 204 and the rubber anti-slip sleeve 205; and since an air intake shroud 302 is fixedly mounted on the bottom of the protective bottom cover 301, and an air inlet slot 3011 is located inside the air intake shroud 302, and an exhaust circular hole A3012 is also provided on the protective bottom cover 301, when the protective bottom cover 301 rotates counterclockwise, external air enters through two of the air intake slots. Under the action of the air diversion hood 302, the air enters the connecting top cover 101 and the protective bottom cover 301 through the corresponding two air inlet slots 3011. The air in the connecting top cover 101 and the protective bottom cover 301 is discharged through a ring of exhaust holes A3012. When the protective bottom cover 301 rotates clockwise, the external air enters the connecting top cover 101 and the protective bottom cover 301 through the corresponding two air inlet slots 3011 under the action of the other two air diversion hoods 302. The air in the connecting top cover 101 and the protective bottom cover 301 is discharged through a ring of exhaust holes A3012, which increases the air flow speed in the connecting top cover 101 and the protective bottom cover 301 and is conducive to the heat dissipation in the connecting top cover 101 and the protective bottom cover 301.

[0048] In this embodiment of the disclosure, such as Figure 3 and Figure 7 As shown, the connecting assembly 400 includes: a rectangular plate 401 and a movable connecting bracket 402; the rectangular plate 401 is fixedly mounted on the protective bottom cover 301, and the rectangular plate 401 has an exhaust hole B4011, which is aligned with the exhaust hole A3012; the movable connecting bracket 402 is slidably mounted on the rectangular plate 401, and is also inserted into the limiting slot 1012; the connecting assembly 400 also includes: an adjusting screw 403 and a helical spring 404; the adjusting screw 403 is inserted into the movable connecting bracket 402, and is also threadedly connected to the protective bottom cover 301; the helical spring 404 is sleeved on the outside of the adjusting screw 403, and is located between the protective bottom cover 301 and the movable connecting bracket 402;

[0049] Its specific function is as follows: Since the movable connecting frame 402 is slidably installed on the rectangular plate 401, and the movable connecting frame 402 is also inserted into the limiting slot 1012, it plays a limiting role for the protective bottom cover 301, preventing the protective bottom cover 301 from falling off the connecting top cover 101. At the same time, the movable connecting frame 402 and the limiting slot 1012 also play a limiting role for the rotation angle of the protective bottom cover 301, ensuring that when the movable connecting frame 402 rotates to the other side of the limiting slot 1012, the other two circular conductive rods 505 just contact the two rectangular conductive pieces 102.

[0050] Furthermore, since the adjusting screw 403 is inserted into the movable connecting bracket 402 and is also threadedly connected to the protective bottom cover 301, when the protective bottom cover 301 needs to be separated from the connecting top cover 101, the operator can rotate the adjusting screw 403 with a screwdriver to move the movable connecting bracket 402 inward, facilitating the separation of the movable connecting bracket 402 from the limiting slot 1012. Also, since the helical spring 404 is sleeved on the outside of the adjusting screw 403 and is located between the protective bottom cover 301 and the movable connecting bracket 402, when the protective bottom cover 301 needs to be connected to the connecting top cover 101, the operator can rotate the adjusting screw 403 in the opposite direction with a screwdriver to move the movable connecting bracket 402 outward, facilitating the connection of the movable connecting bracket 402 with the limiting slot 1012.

[0051] In this embodiment of the disclosure, such as Figure 8 and Figure 9As shown, the lighting assembly 500 includes: a first LED light 501 and a second LED light 502; the first LED light 501 is installed inside the protective base cover 301, and the first LED light 501 is concentrically arranged with the protective base cover 301; the second LED light 502 is installed on the first LED light 501; the lighting assembly 500 further includes: mounting screws 503 and a hexagonal block 504; two mounting screws 503 are provided, and the two mounting screws 503 are inserted into the first LED light 501 and the second LED light 502, and the two mounting screws 503 are also threadedly connected to the protective base cover 301; the hexagonal block 504 is fixedly installed on the first LED light 501, and the hexagonal block... The outer end of 504 is chamfered, and the hexagonal block 504 is also inserted into the second LED light 502; the lighting assembly 500 also includes: a circular conductive rod 505 and a support screw 506; there are four circular conductive rods 505, and the four circular conductive rods 505 are respectively fixedly installed on the first LED light 501 and the second LED light 502, and the two circular conductive rods 505 on the first LED light 501 are in contact with the two rectangular conductive pieces 102; there are four support screws 506, and the four support screws 506 are respectively threaded to the first LED light 501 and the second LED light 502, and the inner ends of the four support screws 506 are in contact with the protective bottom cover 301;

[0052] Its specific function is as follows: Because the second LED 502 is mounted on the first LED 501, and the hexagonal block 504 is fixedly mounted on the first LED 501, and the hexagonal block 504 is also inserted into the second LED 502, it is beneficial for the first LED 501 and the second LED 502 to be accurately connected, and it is convenient for the two mounting screws 503 to be inserted into the first LED 501 and the second LED 502; and because the four circular conductive rods 505 are respectively fixedly mounted on the first LED 501 and the second LED 502, and the two circular conductive rods 505 on the first LED 501 are connected to the two rectangular blocks 502, the second LED 502 is also fixedly mounted on the first LED 501 and the second LED 502. When the first LED 501 is damaged, the operator can activate the micro motor 203. When the micro motor 203 is working, the protective cover 301 changes angle, causing the two circular conductive rods 505 on the second LED 502 to contact the two rectangular conductive plates 102. When both the first LED 501 and the second LED 502 are damaged, the operator can replace both simultaneously, allowing for twice the usage time with each replacement, reducing the number of repairs. Meanwhile, the user can continue to use the LED, ensuring normal lighting performance.

[0053] Furthermore, since the four support screws 506 are respectively threaded onto the first LED light 501 and the second LED light 502, and the inner ends of the four support screws 506 are in contact with the protective bottom cover 301, when the two circular conductive rods 505 on the first LED light 501 have poor contact with the two rectangular conductive pieces 102, the operator can rotate the two support screws 506 on the first LED light 501 with a screwdriver; when the two circular conductive rods 505 on the second LED light 502 have poor contact with the two rectangular conductive pieces 102, the operator can rotate the two support screws 506 on the second LED light 502 with a screwdriver; when the operator rotates the four support screws 506 with a screwdriver, the first LED light 501 and the second LED light 502 can bend slightly, causing a slight change in the height of the four circular conductive rods 505, which helps to improve the contact effect between the two rectangular conductive pieces 102 and the corresponding two circular conductive rods 505.

[0054] The specific usage and function of this embodiment are as follows:

[0055] When using this invention, the operator first connects a ring of connecting screws 103 to the wall or bracket using a screwdriver or power tool. Then, the protective bottom cover 301 is slidably installed inside the connecting top cover 101. Next, the operator rotates the four adjusting screws 403 using a screwdriver or power tool, so that the four movable connecting brackets 402 are inserted into the four limiting slots 1012. The four movable connecting brackets 402 limit the protective bottom cover 301, preventing it from falling off from the connecting top cover 101. At the same time, the four movable connecting brackets 402 and the four limiting slots 1012 also limit the rotation angle of the protective bottom cover 301, ensuring that when the four movable connecting brackets 402 rotate to the other side of the four limiting slots 1012, the other two circular conductive rods 505 are in contact with the two rectangular conductive pieces 102.

[0056] When the temperature sensor 202 detects that the temperature in the connection between the top cover 101 and the protective bottom cover 301 exceeds a preset temperature value, the temperature sensor 202 transmits the detected temperature information to the controller 201. At this time, the controller 201 controls the output shaft of the micro motor 203 to reciprocate at a certain angle. When the controller 201 controls the output shaft of the micro motor 203 to reciprocate, the two corresponding circular conductive rods 505 will not separate from the two rectangular conductive pieces 102, ensuring that the first LED 501 and the second LED 502 are always energized. When the output shaft of the micro motor 203 reciprocates, the protective bottom cover 301 reciprocates under the action of the circular drive wheel 204 and the rubber anti-slip sleeve 205. When the protective bottom cover 301 rotates counterclockwise... Under the action of two air ducts 302, external air enters the connecting top cover 101 and the protective bottom cover 301 through the corresponding two air inlet slots 3011. The air in the connecting top cover 101 and the protective bottom cover 301 is discharged through a ring of exhaust holes A3012. When the protective bottom cover 301 rotates clockwise, external air enters the connecting top cover 101 and the protective bottom cover 301 through the corresponding two air inlet slots 3011 under the action of the other two air ducts 302. The air in the connecting top cover 101 and the protective bottom cover 301 is discharged through a ring of exhaust holes A3012, which increases the air flow speed in the connecting top cover 101 and the protective bottom cover 301 and is conducive to the dissipation of heat in the connecting top cover 101 and the protective bottom cover 301.

[0057] When the first LED 501 fails, the operator can activate the micro motor 203. When the micro motor 203 operates, the protective cover 301 changes angle, causing the two circular conductive rods 505 on the second LED 502 to contact the two rectangular conductive plates 102. When both the first LED 501 and the second LED 502 fail, the operator can replace both simultaneously, doubling the lifespan of each replacement and reducing maintenance frequency. Meanwhile, the user can continue to use the light, ensuring normal lighting performance. When the two circular conductive rods 505 on the first LED 501 contact the two rectangular conductive plates 102... When the conductive sheet 102 has poor contact, the operator can use a screwdriver to rotate the two support screws 506 on the first LED 501; when the two circular conductive rods 505 on the second LED 502 have poor contact with the two rectangular conductive sheets 102, the operator can use a screwdriver to rotate the two support screws 506 on the second LED 502; when the operator rotates the four support screws 506 with a screwdriver, the first LED 501 and the second LED 502 can bend slightly, causing a slight change in the height of the four circular conductive rods 505, which helps to improve the contact effect between the two rectangular conductive sheets 102 and the corresponding two circular conductive rods 505;

[0058] When the protective bottom cover 301 needs to be separated from the connecting top cover 101, the operator uses a screwdriver or power tool to turn the four adjusting screws 403, causing the four adjusting screws 403 to move the four movable connecting brackets 402 inward, so that the four movable connecting brackets 402 can be separated from the four limiting slots 1012; when the protective bottom cover 301 needs to be connected to the connecting top cover 101, the operator uses a screwdriver or power tool to turn the four adjusting screws 403 in the opposite direction, causing the elastic force of the four coil springs 404 to move the four movable connecting brackets 402 outward, so that the four movable connecting brackets 402 can be connected to the four limiting slots 1012.
