[0079] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0080] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0081] The following embodiments of the present application provide a lighting device that solves the problems of a single installation scenario for the lighting device, a complex product connection process, high cost, insufficient cable strength, and the need for auxiliary steel wire rope installation.

[0082] The principle and implementation of the lighting device of this embodiment will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the lighting device of this embodiment without creative work.

[0083] See also Figure 1 , which is a schematic diagram of an explosion of the lighting device product of the utility model. Figure 1 As shown, this embodiment provides a lighting device, which includes: a lamp head 11, a light source cover 12, and a light bar 13;

[0084] The lamp holder 11 comprises an upper shell 111 and a lower shell 112, wherein the upper shell 111 is adapted to the lower shell 112 and fixed to each other to form a receiving cavity; a through hole 113 is provided at the bottom of the lower shell 112;

[0085] The light source cover 12 is detachably connected to the lamp holder 11 through the through hole 113 at the bottom of the lower housing 112;

[0086] A circuit board 131 is disposed at one end of the light bar 13 . The light bar circuit board 131 is accommodated in the accommodating cavity. The other end of the light bar 13 extends into the interior of the light source cover 12 through the through hole 113 .

[0087] Specifically, the upper shell of the lamp holder is adapted to the lower shell, and they are fixedly connected to each other by threaded engagement, snap-on fixing, bonding or other mechanical connection methods to form a housing cavity. The housing cavity is a closed space formed after the upper and lower shells are fixed, and is used to place and protect internal electronic components to prevent the intrusion of dust, moisture and other external factors; the design of the housing cavity takes into account air circulation to facilitate the dissipation of internal heat, ensure the normal operation of electronic components and extend their service life. A sealing ring or sealing gasket is provided at the junction of the upper and lower shells to improve the overall waterproof and dustproof performance. Furthermore, the sealing design achieved by means of air holes or breathable membranes allows a certain air pressure balance, for example, to prevent deformation of the shell due to changes in air pressure.

[0088] Furthermore, the lighting device also includes a solar panel 15 and a control module 14;

[0089] The solar panel 15 is fixed on the top of the upper housing 111;

[0090] The control module 14 is fixed inside the accommodating cavity and is electrically connected to the solar panel 15 and the circuit board 131 .

[0091] Furthermore, the electrical connection between the light bar circuit board 131 and the control module 14 adopts a detachable connection design. For example, the light bar circuit board 131 is electrically connected to the control module 14 by riveting, welding, or male and female terminal plug-in. Such a design facilitates maintenance and replacement. If the light bar or control module fails, they can be easily separated for maintenance or replacement without replacing the entire system. At the same time, with the development of technology, the control module may need to be upgraded to support new functions or improve performance. The detachable connection makes the upgrade process simpler, and only the control module 14 needs to be replaced.

[0092] See also Figures 1 to 5 , Figure 2 The figure shows a schematic diagram of the buckle structure of the lighting device of the utility model. Figure 5 The figure shows the lower shell of the lighting device of the present invention. Figure 2 , Figure 5 As shown, the open end of the light source cover 12 is provided with a first snap-fit ​​structure 121, which is adapted to the second snap-fit ​​structure 21 inside the through hole 113 to achieve snap-fit ​​connection. The bottom of the lower shell 112 is provided with a through hole 113, and the light source cover 12 is detachably connected to the lamp holder 11 through the through hole 113 at the bottom of the lower shell 112.

[0093] Specifically, please combine Figure 7, which is an axonometric view of the lighting device described in the embodiment of the present application. A first buckle structure 121 is provided on the top of the light source cover 12, and this structure matches the second buckle structure 21 on the inner side of the concave wall of the middle through hole 113 structure of the lower shell. When the first buckle structure 121 on the top of the light source cover 12 is aligned and pressed with the second buckle structure 21 of the lower shell 112, the buckle will enter the groove of the female buckle due to its elasticity, and be fixed therein by the barb or locking edge of the buckle, thereby realizing the fixed connection between the light source cover 12 and the lower shell 112. This design allows the light source cover to be connected and separated from the lamp head by a simple "click" operation, without the use of tools, convenient for disassembly and installation, and easy for users to operate. In addition, based on the independence of the light source cover structure, that is, the light source cover is completely independent of the light bar and the light bar circuit board, that is, the rotation of the light source cover will not drive the light bar to rotate. This shows that the buckle connection design allows the light source cover to move freely within a certain range without interfering with the internal electronic components, especially the light bar. Such a design can reduce the damage to internal components caused by improper operation.

[0094] See also Figure 3 and Figure 4 , showing a schematic diagram of the upper cavity and the lower cavity of the upper shell of the lighting device of the present invention. As shown in the figure, the upper shell 111 includes an upper cavity 31 and a lower cavity 41;

[0095] The upper cavity 31 is provided with a wire outlet hole 311, and the wire outlet hole 311 is used to lead out the wires of the solar panel 15 and connect them to the control module 14;

[0096] The lower cavity 41 is provided with a battery compartment 411 and upper and lower cavity screw columns 412. The battery compartment 411 is used to accommodate the battery 16 and connect to the control module 14. The upper and lower cavity screw columns 412 are used to fix the upper and lower cavities. The inner side of the edge wall of the lower cavity 41 is provided with a downward double-layer step structure 413, which adopts a step design with a wide upper layer and a narrow lower layer.

[0097] Specifically, a downward double-layer step structure 413 is provided on the inner side of the edge wall of the lower cavity 41, and the upper width of the double-layer step is greater than the lower width. This double-layer step design can increase the rigidity and structural stability of the lower cavity, especially when the upper shell 111 is combined with the lower shell 112, the wider upper step can provide a wider support area, ensure uniform force, and reduce deformation or damage caused by external force.

[0098] like Figure 3 As shown, a first mounting hole 312 is provided on one side of the upper shell 111 for hanging the lighting device on an external structure; at least two hanging holes 313 are provided on both sides of the edge of the upper shell 111 for hanging the lighting device by hooks in cooperation with the mounting holes. Further, the mounting holes are semi-enclosed structures.

[0099] In one embodiment, the first mounting hole on one side of the upper shell is located at the center or one side of the upper shell so as to keep the lighting device balanced when hanging; the mounting hole is designed as a semi-enclosed structure, and the semi-enclosed mounting hole can effectively prevent moisture from directly entering the interior of the device. This design utilizes physical barriers and gravity, so that even if water splashes on the device from the outside, it is difficult for water to enter through the mounting hole, thereby protecting the internal electronic components from water damage. This is especially important for solar light strings used outdoors, as they are often exposed to changing weather conditions. The semi-enclosed mounting hole can also reduce the entry of small particles such as dust and insects into the interior of the device. This not only helps to maintain the cleanliness of the interior of the device and extend the life of the device, but also prevents faults such as circuit short circuits caused by insect invasion. The semi-enclosed mounting hole reduces safety hazards during use to a certain extent. For example, it can prevent children's fingers or other objects from accidentally inserting into the power hole, thereby avoiding electric shock accidents.

[0100] There should be at least two hanging holes, located on both side edges of the upper shell to provide stable hanging points; the hanging holes on both sides of the edge are set to be groove-shaped or oval-shaped to accommodate the insertion of hooks in different positions, provide more hanging point options, and enhance the flexibility and adaptability of the hanging. The hanging holes can be matched with plug-ins made of elastic materials (such as rubber or silicone), which can compress and adapt to hooks of different diameters while providing anti-slip functions. The position of the hanging hole cooperates with the first mounting hole to ensure the stability of the lighting device when hanging. Furthermore, one end of the hook hooks the hanging hole, and the other end is fixed to the external structure, and the hook and the hanging hole are quickly connected and disconnected through a buckle or a screw mechanism.

[0101] See also Figure 5 a to Figure 5 c, Figure 5 a is a schematic diagram showing the positioning structure of the lower shell of the lighting device. Figure 5 b is a bottom view of the lower housing of the lighting device. The lower housing includes a positioning structure 51, a second mounting hole 52, a water leakage hole 53 and a switch hole 54;

[0102] The positioning structure 51 includes upper and lower housing screw columns 511, battery positioning columns 512, control module screw columns 513, and light bar circuit board screw columns 514; the upper and lower housing screw columns 511 are used to fix the upper and lower housings, the battery positioning columns 512 are used to fix the battery 16, the control module screw columns 513 are used to fix the control module 14, and the light bar circuit board screw columns 514 are used to fix the light bar circuit board 131;

[0103] The second mounting hole 52 is adapted to fit into the first mounting hole 312 and is used for further mounting additional components;

[0104] The water leakage hole 53 is arranged at the lower part of the mounting hole 52, and adopts a conical structure design with a small top and a large bottom;

[0105] The switch hole 54 is disposed outside the through hole 113 and is used for installing a switch and operating the switch through the hole.

[0106] There is at least one drainage channel provided at the bottom of the water leakage hole 53, which is used to guide the liquid to the outside of the lighting device when the liquid enters the installation hole 52, so as to prevent the accumulation of water from damaging the electronic components.

[0107] Specifically, in lighting devices, especially for lighting devices used outdoors or in humid environments, leak holes are usually set at the bottom of the mounting hole. This design uses gravity so that any liquid entering the mounting hole can naturally flow to the leak hole. A conical structure with a small top and a large bottom is adopted, which helps to guide the liquid to flow downward and prevent the liquid from accumulating at the hole, thereby reducing the potential threat to electronic components; at least one drainage channel is provided at the bottom of the leak hole. These channels serve as the outlet of the liquid and can effectively guide the liquid to the outside of the lighting device to avoid the accumulation of water inside the device. The main function of the leak hole and the drainage channel is waterproof protection. When liquid accidentally enters the mounting hole, these designs can quickly drain the liquid, greatly reducing the risk of short circuit or corrosion of electronic equipment caused by moisture accumulation. By effectively removing moisture, the design of the leak hole and the drainage channel improves the stability and life of the lighting device in a humid or outdoor environment. The design reduces equipment failures caused by moisture, thereby reducing maintenance costs and frequency. This is particularly important for lighting devices installed outdoors or at high places where frequent maintenance is difficult.

[0108] See also Figure 5 c, shows a schematic diagram of the switch hole of the lower shell of the lighting device of the utility model. Figure 5 As shown in Figure c, the switch hole 54 is located on the outside of the lower shell 112 and is arranged outside the through hole 113. This design allows the user to operate the switch directly from the outside without disassembling the product. This not only makes the operation more convenient, but also avoids the damage that may be caused by frequent disassembly, and also improves the waterproof and dustproof performance of the product. By setting the switch hole in an easily accessible position, it ensures that the user can easily turn on or off the light string without having to find other tools or perform complicated operating steps. This intuitive design is user-friendly for users of all ages. The setting of the switch hole position also helps to protect the internal electronic components from the influence of the external environment, such as moisture, dust, etc. that may enter the interior of the device through the switch hole. Since the switch hole is located outside the through hole, this design can better seal the internal space and reduce the direct impact of the external environment on the circuit.

[0109] Furthermore, a sealing device is provided on the periphery of the switch hole 54, and the sealing device includes a rubber gasket or a waterproof sealant to prevent moisture from entering the accommodating cavity through the switch hole.

[0110] In one embodiment, please combine Figures 1 to 7 , Figure 7 The figure shows the assembly diagram of the lighting device according to the embodiment of the present application. The steps for installing the lighting device provided in the present application are as follows:

[0111] S1. Installing the solar panel: First, the solar panel 15 is fixed to the upper cavity 31 of the upper shell 111 by gluing. The positive and negative wires are inserted through the positive and negative outlet holes of the upper cavity 31, and the bottoms of these holes are injected with glue for waterproofing.

[0112] S2. Connecting wires to control module: The inserted positive and negative wires are welded to the control module 14 such as a printed circuit board, or other connection methods such as riveting, wire terminal plugging, etc. can also be used in this step to achieve electronic connection.

[0113] S3. Install the battery: Place the battery 16 in the battery compartment 411 in the upper housing 111 , and ensure that the wires in the battery compartment 411 are correctly connected to the control module 14 so that power can be transmitted from the battery to the control module 14 .

[0114] S4. Fix the light bar circuit board: The light bar circuit board 131 is placed on the lower shell 112 and fixed on the light bar circuit board screw column 514 by means of screws or buckles to ensure the stability of the circuit board.

[0115] S5. Connecting the light bar and the circuit board: The light bar 13 and the light bar circuit board 131 are physically and electronically connected by riveting, welding, or plugging male and female terminals. Subsequently, the light bar 13 and the light bar circuit board 131 are connected to the control module 14 through wires, and these wires can pass through the through hole 113 of the lower shell 112 from the internal cavity, or can also pass through from the outside.

[0116] S6. Install the switch: The switch 17 is installed into the lower housing 112 through the switch hole 54 of the lower housing 112. This design allows the user to directly operate the switch without disassembling the product, which increases the convenience of use and helps to prevent water and dust.

[0117] S7, assembling the upper and lower shells: The upper and lower shells are connected by upper and lower shell screw posts 511. Once the upper and lower shells are assembled, the battery positioning posts 512 will abut the battery to prevent it from moving inside.

[0118] S8, fix the light source cover: Finally, the light source cover 12 is inserted into the through hole 113 of the lower housing 112 from the outside and fixed by buckles. This design ensures the independence of the light source cover 12, the light bar 13 and the light bar circuit board 131, so that the rotation of the light source cover 12 will not affect the position of the light bar 13.

[0119] S9. Suspension device: If suspension is required, the suspension holes 313 on both sides of the upper shell can be used to install the hooks 18 to facilitate the suspension of the entire lighting device.

[0120] S10, check the water leakage holes: The bottom of the installation hole is designed with water leakage holes 53 for waterproofing and drainage. During the installation process, it should be ensured that these water leakage holes are not blocked to ensure their function.
