Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to an LED lighting device with autonomous brightness control. Background Art

[0002] In the field of lighting technology, LED lighting devices are widely used in various scenarios due to their advantages such as energy saving and long life. LED lighting devices with autonomous brightness control, which can flexibly adjust brightness according to actual needs, further enhance convenience and applicability, have become a hot topic of research and application within the industry.

[0003] Existing LED lighting devices often use screw fastening or snap-on nesting to connect the housings. For example, when the upper and lower housings are secured with screws, repairing or replacing the LED light panel requires removing the screws one by one with a screwdriver or other tool. This is a cumbersome and time-consuming process, and particularly inefficient when there are a large number of screws. While some snap-on nesting structures simplify the installation process to some extent, they can easily become stuck and difficult to separate during disassembly due to improper snap-on design, or even become damaged during forced disassembly. This compromises the sealing and stability of the entire device, posing a safety hazard during subsequent use. These issues arise because existing connection structures fail to adequately consider the ease of routine maintenance and structural reliability, lacking designs for quick positioning, efficient assembly and disassembly, and secure positioning. These issues result in users wasting significant time and effort when repairing or replacing LED lighting devices, while also increasing the risk of damage from improper assembly and disassembly, severely impacting the user experience and device lifespan. Therefore, the present invention provides an LED lighting device with autonomous brightness control to address these issues. Utility Model Content

[0004] The purpose of the present invention is to provide an LED lighting device with autonomous brightness control to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] An LED lighting device with autonomous brightness control comprises an upper shell and a lower shell movably connected to the upper shell, an LED light board is installed inside the upper shell, a circuit board is installed on the LED light board, a dimmer capable of adjusting the brightness of the lower shell is installed on the circuit board, the upper shell and the lower shell are arranged correspondingly in the upper and lower parts, and no less than two L-shaped blocks are installed on the upper wall surface of the lower shell in a counterclockwise direction and at equal intervals, the lower wall surface of the upper shell is provided with an L-shaped connecting groove for movably engaging the L-shaped block, a limiting mechanism for limiting the L-shaped block is provided on the upper shell, an auxiliary pushing mechanism for facilitating the separation of the upper shell and the lower shell is provided inside the L-shaped connecting groove, and heat dissipation holes are provided on the inner wall surface of the lower shell for heat dissipation.

[0007] Preferably, the limiting mechanism includes a movable hole and a limiting block, and a movable hole is provided on the outer wall of the upper shell body at a position corresponding to the L-shaped connecting groove, and the movable hole is a hole with an L-shaped cross-section, and the internal movable clamping of the movable hole is provided with a limiting block that can move up and down, and the limiting block is a block of L-shaped structure, and the horizontal end free end of the limiting block passes through the interior of the movable hole and extends to the outside of the upper shell body, and the vertical end free end of the limiting block extends downward to the interior of the L-shaped connecting groove, and the upper wall surface of the L-shaped clamping block is provided with a limiting groove for being movably clamped with the upper vertical end of the limiting block.

[0008] Preferably, the auxiliary pushing mechanism includes a mounting groove, a spring and a push block, a mounting groove is provided on the inner wall surface of the counterclockwise side of the L-shaped connecting groove, a spring is fixedly connected to the inside of the mounting groove, and the free end of the spring extends to the inside of the L-shaped connecting groove, a movable push block is provided inside the L-shaped connecting groove, and the push block is fixedly connected to the free end of the spring.

[0009] Preferably, a U-shaped fixing block is fixedly connected to the position of the heat dissipation hole on the inner wall surface of the lower shell, and a rotatable connecting column is movably connected to the position of the heat dissipation hole on the side wall surface of the inner part of the U-shaped fixing block away from the lower shell through a bearing, and a spiral sheet is fixedly connected to the outer wall surface of the connecting column.

[0010] Preferably, the spiral piece is a spiral block, and one end of the spiral piece away from the U-shaped fixing block is located inside the corresponding heat dissipation hole.

[0011] Preferably, at least two through holes are formed on a side wall of the U-shaped fixing block close to the interior of the lower shell.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model solves the problem of existing LED lighting devices that require cumbersome disassembly procedures when repairing and replacing internal components, requiring the use of tools to remove multiple screws or components, resulting in time-consuming and labor-intensive maintenance, through the coordinated integration of an upper shell, a lower shell, an L-shaped block, an L-shaped connecting groove, a limiting mechanism (movable holes and limiting blocks), and an auxiliary ejection mechanism (mounting grooves, springs, and ejection blocks). During assembly, the L-shaped blocks of the upper and lower shells are aligned and joined with the L-shaped connecting grooves. The lower shell is then rotated to complete the connection, with the limiting blocks automatically locking. During disassembly, the limiting blocks are moved, and the spring of the auxiliary ejection mechanism pushes the ejection block out of the L-shaped block. The lower shell is then rotated to complete the separation, greatly simplifying the repair and replacement process and improving the maintainability and service life of the device.

[0014] 2. The present invention utilizes a lower housing with heat dissipation holes in its inner wall, along with a U-shaped fixing block, connecting column, and spiral blades that cooperate with the heat dissipation holes. When the hot air generated by the LED light panel is discharged through the heat dissipation holes, it drives the spiral blades to rotate and form a barrier. This solves the problem of existing LED lighting devices where the heat dissipation holes are susceptible to insects attracted to the light, leading to accumulation of insect carcasses that affect the light source, and a simple heat dissipation structure that results in poor heat dissipation.

[0015] 3. The curved surface at the vertical end of the limit block not only facilitates the L-shaped block to lift the limit block during assembly, but also reduces friction and wear between the L-shaped block and the limit block to a certain extent. During multiple assembly and disassembly processes, the curved surface design ensures smoother contact between the two, reducing the risk of component damage due to friction, extending the service life of the limit mechanism, and ensuring the long-term stability of the device connection structure.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 In the embodiment of the present invention, an LED lighting device with autonomous brightness control includes an upper shell 1 and a lower shell 2 movably connected to the upper shell 1. An LED light board 3 is installed inside the upper shell 1, and a circuit board 4 is installed on the LED light board 3. A dimmer 5 capable of adjusting the brightness of the lower shell 2 is installed on the circuit board 4. The LED light board 3, the circuit board 4 and the dimmer 5 are all existing technologies and will not be discussed here. The connection methods between the LED light board 3 and the circuit board 4 and between the circuit board 4 and the dimmer 5 are all existing connection methods and will not be discussed here. When in use, the LED light board 3 is turned on and off by a controller electrically connected to the circuit board 4. In combination with the dimmer 5 installed on the circuit board 4, the effect of autonomously controlling the brightness of the LED light board 3 can be achieved. The upper shell 1 and the lower shell 2 are arranged correspondingly in the upper and lower parts. The lower shell 2 is arranged below the upper shell 1, and no less than two L-shaped blocks 6 are installed equidistantly counterclockwise on the upper wall of the lower shell 2. The lower wall of the upper shell 1 is provided with an L-shaped connecting groove 8 for movably connecting the L-shaped block 6. The L-shaped block 6 can enter the interior of the L-shaped connecting groove 8 at the opening on the upper shell 1 through the L-shaped connecting groove 8. The number of L-shaped connecting grooves 8 is the same as the number of L-shaped blocks 6. A limiting mechanism for limiting the L-shaped block 6 is provided on the upper shell 1, and an auxiliary pushing mechanism for facilitating the separation of the upper shell 1 and the lower shell 2 is provided inside the L-shaped connecting groove 8. Heat dissipation holes 14 for heat dissipation are provided on the inner wall of the lower shell 2. The number of heat dissipation holes 14 can be opened according to actual conditions and is not limited here. The heat generated by the LED light board 3 during operation can be discharged through the heat dissipation holes 14.

[0025] The limiting mechanism includes a movable hole 9 and a limit block 10. A movable hole 9 is provided on the outer wall of the upper shell 1 at a position corresponding to the L-shaped connecting groove 8. The movable hole 9 corresponds to the horizontal end position of the inner side of the L-shaped connecting groove 8. The movable hole 9 is a hole with an L-shaped cross section. The inner side of the movable hole 9 is movably connected with a limit block 10 that can move up and down. The limit block 10 is a block of L-shaped structure. The horizontal end free end of the limit block 10 passes through the interior of the movable hole 9 and extends to the outside of the upper shell 1. The vertical end free end of the limit block 10 extends downward to the interior of the L-shaped connecting groove 8. The upper wall surface of the L-shaped block 6 is provided with a limiting groove 7 for movably connecting with the upper vertical end of the limit block 10. The counterclockwise side wall surface of the vertical end of the limit block 10 is provided with an arc surface. The internal shape and size of the limit groove 7 are adapted to the shape and size of the vertical end of the limit block 10. Figure 5 shown.

[0026] When the upper shell 1 and the lower shell 2 need to be assembled together during use, first align the L-shaped connecting groove 8 on the upper shell 1 with the corresponding L-shaped block 6 on the lower shell 2, and then merge the upper shell 1 and the lower shell 2 together. At this time, the L-shaped block 6 enters the corresponding L-shaped connecting groove 8, and then rotates the lower shell 2 counterclockwise so that the upper horizontal end of the L-shaped block 6 enters the position of the horizontal end inside the L-shaped connecting groove 8, thereby completing the effect of movably connecting the L-shaped block 6 to the inside of the L-shaped connecting groove 8. At the same time, since the vertical end of the limit block 10 is located inside the L-shaped connecting groove 8, and its counterclockwise side wall surface is provided with an arc surface, when the upper horizontal end of the L-shaped block 6 enters the horizontal end inside the L-shaped connecting groove 8, under the influence of the arc surface on the limit block 10, the L-shaped block 6 enters the inside of the L-shaped connecting groove 8 and pushes up the limit block 10, causing it to move upward inside the movable hole 9 and retract into the movable hole 9. The staff who lost the limit block 10 at this time can rotate the lower shell 2 clockwise to separate the L-shaped block 6 from the inside of the L-shaped connecting groove 8, thereby achieving the effect of quickly disassembling the upper shell 1 and the lower shell 2, and conveniently repairing and replacing the LED light board 3.

[0027] The auxiliary pushing mechanism includes a mounting groove 11, a spring 12 and a top block 13. The mounting groove 11 is opened on the inner wall surface of the counterclockwise side of the L-shaped connecting groove 8. The spring 12 is fixedly connected to the inside of the mounting groove 11, and the free end of the spring 12 extends to the inside of the L-shaped connecting groove 8. A movable top block 13 is provided inside the L-shaped connecting groove 8, and the top block 13 is fixedly connected to the free end of the spring 12.

[0028] When in use, when the L-shaped block 6 is completely inserted into the interior of the L-shaped connecting groove 8, the L-shaped block 6 will squeeze the top block 13 to move it in the counterclockwise direction. At this time, the spring 12 is deformed by the force and retracts into the interior of the installation groove 11. When the staff pushes the limit block 10 upward to separate it from the interior of the limit groove 7, the elastic force generated by the restoration of the deformation of the installation groove 11 will push the spring 12 to move in the clockwise direction, thereby achieving the effect of popping the L-shaped block 6 out of the interior of the L-shaped connecting groove 8, completing the disassembly between the upper shell 1 and the lower shell 2, and further improving the convenience during disassembly.

[0029] A U-shaped fixing block 15 is fixedly connected to the position of the heat dissipation hole 14 on the inner wall surface of the lower shell 2. The dimmer 5 is a U-shaped structure. The inner side wall surface of the U-shaped fixing block 15 away from the lower shell 2 is connected to the position of the heat dissipation hole 14 through a bearing. A spiral piece 17 is fixedly connected to the outer wall surface of the connecting column 16. The connecting column 16 and the spiral piece 17 are supported by lightweight materials, such as nylon, to reduce their own weight and facilitate rotation.

[0030] The spiral piece 17 is a spiral block, and one end of the spiral piece 17 away from the U-shaped fixing block 15 is located inside the corresponding heat dissipation hole 14, as shown in FIG. Figure 6 As shown, when air flows through the heat dissipation hole 14 , the connecting column 16 will rotate under the influence of the spiral sheet 17 .

[0031] Heat will be generated during the operation of the LED light board 3. The hot air flow generated by the heat generation of the LED light board 3 is easily discharged through the heat dissipation holes 14 on the lower shell 2. When the hot air flow is discharged through the heat dissipation holes 14, it will contact the spiral piece 17, and then the spiral piece 17 will drive the connecting column 16 to rotate. Therefore, during the operation of the LED light board 3, the structure composed of the connecting column 16 and the spiral piece 17 will always maintain a rotating state inside the heat dissipation hole 14, which can effectively prevent insects from passing through the inside of the lower shell 2 inside the heat dissipation hole 14 under the influence of phototaxis, thereby avoiding the problem of a large number of insect corpses accumulating inside the lower shell 2 after a long time, affecting the light source.

[0032] The U-shaped fixing block 15 has at least two through holes 18 on one side wall near the interior of the lower shell 2. The through holes 18 on the U-shaped fixing block 15 can effectively prevent the hot air flow inside the lower shell 2 from being affected by the U-shaped fixing block 15, resulting in poor fluidity.

[0033] The working principle of this utility model is:

[0034] When the upper shell 1 and the lower shell 2 need to be assembled together during use, first align the L-shaped connecting groove 8 on the upper shell 1 with the corresponding L-shaped block 6 on the lower shell 2, and then merge the upper shell 1 and the lower shell 2 together. At this time, the L-shaped block 6 enters the corresponding L-shaped connecting groove 8, and then rotates the lower shell 2 counterclockwise so that the upper horizontal end of the L-shaped block 6 enters the position of the horizontal end inside the L-shaped connecting groove 8, thereby completing the effect of movably connecting the L-shaped block 6 to the inside of the L-shaped connecting groove 8. At the same time, since the vertical end of the limit block 10 is located inside the L-shaped connecting groove 8, and its counterclockwise side wall surface is provided with an arc surface, when the upper horizontal end of the L-shaped block 6 enters the horizontal end inside the L-shaped connecting groove 8, under the influence of the arc surface on the limit block 10, the L-shaped block 6 enters the inside of the L-shaped connecting groove 8 and pushes up the limit block 10, causing it to move upward inside the movable hole 9 and retract into the movable hole 9. The staff who lost the limit block 10 at this time can rotate the lower shell 2 clockwise to separate the L-shaped block 6 from the inside of the L-shaped connecting groove 8, thereby achieving the effect of quickly disassembling the upper shell 1 and the lower shell 2, and conveniently repairing and replacing the LED light board 3.

[0035] Heat will be generated during the operation of the LED light board 3. The hot air flow generated by the heat generation of the LED light board 3 is easily discharged through the heat dissipation holes 14 on the lower shell 2. When the hot air flow is discharged through the heat dissipation holes 14, it will contact the spiral piece 17, and then the spiral piece 17 will drive the connecting column 16 to rotate. Therefore, during the operation of the LED light board 3, the structure composed of the connecting column 16 and the spiral piece 17 will always maintain a rotating state inside the heat dissipation hole 14, which can effectively prevent insects from passing through the inside of the lower shell 2 inside the heat dissipation hole 14 under the influence of phototaxis, thereby avoiding the problem of a large number of insect corpses accumulating inside the lower shell 2 after a long time, affecting the light source.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
