Description

Technical Field

[0001] This utility model relates to the field of LED light bead technology, and in particular to a protective LED light bead. Background Technology

[0002] An LED light is a lighting device that uses light-emitting diodes (LEDs) as its light source. An LED is a semiconductor device that can directly convert electrical energy into light energy; it emits light by releasing energy when electrons and holes recombine within the semiconductor material. The LED chip is the main functional structure of an LED light.

[0003] Many LED chips have fixed and open heat dissipation structures, which can meet the heat dissipation requirements under normal conditions. However, when the chips are installed in harsh dusty or humid environments, dust can easily enter the interior through the heat dissipation structure, affecting the performance and lifespan of the chips. Humid air may also cause problems such as short circuits. Therefore, a protective LED chip is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a protective LED bead, aiming to improve the problem of poor adaptability of existing LED beads to different environments, which affects their service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective LED bead includes a mounting box. A fixing block is fixedly connected to the rear end of the mounting box. A movable hole is provided inside the fixing block. Two pressing rods are slidably connected to the inner wall of the movable hole. A connecting plate is fixedly connected to the front side of the pressing rods. A locking rod is fixedly connected to the front side of the connecting plate. A spring is fixedly connected to the adjacent side of the two locking rods. A cavity is provided inside the rear side of the mounting box. A grid plate is slidably connected to the inner wall of the cavity. A control plate is fixedly connected to the top of the grid plate. Two locking slots are respectively provided on the left and right sides of the control plate. A protective component for protecting the LED bead is fixedly connected inside the mounting box.

[0007] As a further description of the above technical solution:

[0008] The protective assembly includes two elastic plates. The far side of the two elastic plates is fixedly connected to the inner walls of the left and right sides of the mounting box, and the near side of the two elastic plates is fixedly connected to the lamp body. The front side of the mounting box has a groove.

[0009] As a further description of the above technical solution:

[0010] A sealing strip is fixedly connected to the inner wall of the groove, and two mounting holes are respectively opened on the left and right sides of the mounting box, with bolts threaded to the inner wall of the mounting holes;

[0011] As a further description of the above technical solution:

[0012] The outer wall of the bolt is slidably connected to a positioning block, and a mounting frame is fixedly connected to one side of the plurality of positioning blocks. A transparent plate is fixedly connected to the inner wall of the mounting frame.

[0013] As a further description of the above technical solution:

[0014] The inner walls of the plurality of positioning blocks are slidably connected to the left and right outer walls of the mounting box, and the rear side of the mounting frame is in contact with the front side of the sealing strip;

[0015] As a further description of the above technical solution:

[0016] The mounting box has heat dissipation holes inside, and the inside of the heat dissipation holes is in contact with the outside of the cavity. The mounting box also has a cable management hole on the rear side.

[0017] As a further description of the above technical solution:

[0018] The two connecting plates are externally slidably connected to the inside of the mounting box, and the inner wall of the slot engages with the outer wall of the lever;

[0019] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the LED light is installed in a harsh dusty or humid environment, pressing the pressing rod in conjunction with the connecting plate moves the locking rod towards the center. This movement of the locking rod compresses the spring. After the locking rod disengages from the slot on the control board, pressing down on the control board causes the grille plate to close the heat dissipation holes. Then, the locking rod re-engages with the slot under the action of the spring to secure it. This structure allows the LED light beads to dissipate heat through the heat dissipation holes under normal conditions, and to close the holes in harsh environments to prevent dust and humid air from entering, thereby improving the adaptability of the LED light beads to different usage environments.

[0023] 2. In this invention, when the mounting box is subjected to vibration, the elastic plate will undergo elastic deformation according to the direction and amplitude of the vibration, absorbing the vibration energy and reducing the vibration amplitude transmitted to the LED bead body, directly providing shock absorption and protection for the LED bead body. The sealing strip in the groove on the front side of the mounting box cooperates with the mounting frame to prevent dust and moisture from entering the mounting box from the front and affecting the LED bead body. The transparent plate on the inner wall of the mounting frame can also provide physical protection for the LED bead body without affecting its light emission, preventing external objects from directly contacting the LED bead body. Through the combined effect of these structures, all-round protection for the LED bead body is achieved. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a protective LED bead, including a mounting box 1. A fixing block 2 is fixedly connected to the rear end of the mounting box 1. The fixing block 2 has an internal movable hole 3. Two pressing rods 4 are slidably connected to the inner wall of the movable hole 3. The fixing block 2 mainly provides the basic structure for the installation and support of components such as the movable hole 3 and the pressing rods 4. It ensures the correct positioning and stable movement of the pressing rods 4 during operation. The shape of the pressing rods 4 is closely adapted to the inner wall of the movable hole 3 to ensure smooth sliding during pressing. A connecting plate 5 is fixedly connected to the front side of the pressing rods 4. The two connecting plates 5 are slidably connected to the inside of the mounting box 1. A locking rod 6 is fixedly connected to the front side of the connecting plate 5. The structure of the connecting plate 5 is designed to effectively transmit the force of the pressing rods 4 and drive the locking rods 6 to move. A spring 7 is fixedly connected to the adjacent side of the two locking rods 6. It is the reset and elastic force providing component in the whole structure. It can generate a suitable compressive force when the locking rods 6 are squeezed to move inward. When the external force disappears, this compressive force will cause the locking rods 6 to move to both sides.

[0033] A cavity 8 is provided on the rear side of the interior of the mounting box 1. A grid plate 9 is slidably connected to the inner wall of the cavity 8. The cavity 8 accommodates the grid plate 9 and provides it with movement space. A control plate 10 is fixedly connected to the top of the grid plate 9. The control plate 10 is used for manual raising and lowering of the grid plate 9. The control plate 10 is slidably connected to the interior of the mounting box 1 on the outside and to the inner wall of the cavity 8 on the bottom. Two slots 11 are provided on the left and right sides of the interior of the control plate 10. The inner wall of the slot 11 engages with the outer wall of the locking rod 6. The shape and size of the slot 11 match the locking rod 6 to ensure that the locking rod 6 can be stably engaged within it, thereby fixing the position of the control plate 10 and the grid plate 9. The mounting box 1 has ventilation holes 12 inside, which are used to ventilate and dissipate heat inside the mounting box 1. The inside of the ventilation holes 12 is in contact with the outside of the cavity 8. When it is necessary to close the ventilation holes 12, the control board 10 is pressed down to move the grille plate 9 downward, thereby closing the ventilation holes 12 and effectively preventing dust and humid air from entering the mounting box 1. The mounting box 1 has a cable management hole 13 on the rear side. The main function of the cable management hole 13 is to facilitate the connection of the LED lamp beads' wires, connecting the external power supply to the lamp bead body 15, while ensuring the overall structural integrity of the mounting box 1.

[0034] Reference Figure 1 and Figure 2The mounting box 1 has a protective assembly for protecting the LED beads. This assembly includes two elastic plates 14. The far sides of the two elastic plates 14 are fixedly connected to the inner walls of the left and right sides of the mounting box 1, while the near sides of the two elastic plates 14 are fixedly connected to the LED bead body 15. The LED bead body 15 is the core light-emitting component of the entire protected LED bead. The elastic plates 14 are mainly used for shock absorption and protection of the LED bead body 15. When the mounting box 1 is subjected to vibration, the elastic plates 14 will elastically deform according to the direction and amplitude of the vibration, absorbing the vibration energy and reducing the vibration amplitude transmitted to the LED bead body 15, thus protecting the LED bead body 15 from vibration damage. A groove 21 is provided on the front side of the mounting box 1. A sealing strip 22 is fixedly connected to the inner wall of the groove 21. The shape and size of the sealing strip 22 are adapted to the groove 21, completely filling the space of the groove 21 and making tight contact with the mounting frame 16 after installation. Two mounting holes 20 are respectively provided on the left and right sides of the mounting box 1, and bolts 19 are threadedly connected to the inner walls of the mounting holes 20. A positioning block 18 is slidably connected to the outer wall of the bolt 19. The shape and size of the positioning block 18 match the left and right outer walls of the mounting box 1, allowing it to accurately align with the left and right sides of the mounting box 1. A mounting frame 16 is fixedly connected to the adjacent side of multiple positioning blocks 18. The mounting frame 16 is installed on the mounting box 1 using the cooperation of the bolt 19 and the mounting hole 20. When subjected to vibration, not only is the lamp bead body 15 itself cushioned, but the entire mounting structure also remains stable. A transparent plate 17 is fixedly connected to the inner wall of the mounting frame 16. The transparent plate 17 can provide a certain degree of physical protection for the lamp bead body 15 without affecting its light emission, preventing external objects from directly contacting the lamp bead body 15. The inner walls of multiple positioning blocks 18 are slidably connected to the left and right outer walls of the mounting box 1, and the rear side of the mounting frame 16 contacts the front side of the sealing strip 22.

[0035] Working principle: The LED body 15 can dissipate heat through the heat dissipation hole 12. When the installation position of the LED is in a harsh dusty or humid environment, by pressing the pressing rod 4 in the middle of the fixing block 2 and driving the connecting plate 5 to move in the middle, the connecting plate 5 moves in the middle and drives the locking rod 6 to move in the middle. The locking rod 6 moves in the middle and releases the locking with the slot 11, compressing the spring 7. At this time, the control board 10 is pressed down, driving the grille plate 9 to move down and sealing the heat dissipation hole 12. After the heat dissipation hole 12 is completely closed, the pressing rod 4 is released. At this time, the locking rod 6 loses external force and moves to both sides due to the pressure generated by the compression of the spring 7 and locks with the slot 11, thereby completing the fixation of the control board 10 and the grille plate 9, improving the adaptability of the LED LED to different usage environments.

[0036] Two elastic plates 14 inside the mounting box 1 provide shock absorption and protection for the LED bead body 15. During installation, the positioning blocks 18 are aligned with the left and right sides of the mounting box 1, and the mounting frame 16 is then installed onto the mounting box 1 using bolts 19 and mounting holes 20. When subjected to vibration, not only is the LED bead body 15 cushioned, but the entire mounting structure remains stable, reducing issues such as component loosening caused by vibration, thus providing comprehensive protection for the LED bead body 15. The sealing strip 22 and groove 21 on the front side of the mounting box 1 work in conjunction with the mounting frame 16 to enhance sealing, preventing dust and moisture from entering the mounting box 1 from the front and affecting the LED bead body 15.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
