Description

A lamp structure that is easy to rotate and install Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and more specifically, to a lighting fixture structure that is easy to rotate and install. Background Technology

[0002] In the field of modern lighting, especially in outdoor landscape lighting and industrial lighting, luminaires need to have a rotating function to achieve flexible adjustment of the illumination angle, thereby meeting diverse lighting needs. Patent application number CN202211594391.5 discloses a smart control system for new energy lighting that can generate electricity through self-circulation. It utilizes a drive control chip to compare and analyze the intensity of sunlight and self-luminous emission, sends control signals to the drive circuit, controls the rotation of the drive motor, and controls the orientation of the solar panel, effectively improving the power generation efficiency of new energy lighting.

[0003] As shown in Figure 1, in the prior art, for lamps that need to rotate, a hardware bracket is usually used as a fixing and supporting component, and a screw is set between the lamp body and the hardware bracket. At the same time, a slot is cut on the hardware bracket to limit the rotation angle of the lamp body.

[0004] Specifically, this traditional structure limits the rotation angle of the lamp body by the engagement of screws on the lamp body with the limiting grooves of the hardware bracket. When the lamp is installed outdoors, under the influence of natural environmental factors, debris such as leaves, fallen branches, and bird droppings can easily enter the gap between the screws and the limiting grooves of the hardware bracket. Over time, this debris will gradually accumulate, not only hindering the normal rotation of the lamp body, but also potentially causing the rotating parts to jam, seriously affecting the lamp's beam angle adjustment function and reducing the convenience and reliability of the lamp's use.

[0005] Furthermore, the hardware bracket in this structure only serves the functions of fixing and limiting rotation, and due to its inherent structural characteristics, it lacks sufficient space to accommodate these components. In practical applications, when the space within the lamp body is limited, the wiring, control modules, and other components of the lamp often require additional installation space. The limitations of the hardware bracket make it difficult to integrate these components effectively, increasing the complexity of lamp assembly and restricting the optimal design of the lamp structure. From an aesthetic perspective, the exposed hardware bracket and screws detract from the overall aesthetics of the lamp and fail to meet users' increasingly sophisticated aesthetic demands for product design.

[0006] Meanwhile, existing hardware brackets are typically designed with a U-shaped structure, generally manufactured using processes such as stamping or sheet metal bending. The holes for fixing the bracket are usually located at the bottom of the bracket. During actual installation, when using screws to fix the bracket to the mounting surface, the presence of the lamp body interferes with the screw-fixing operation. Installers must operate in confined spaces, which not only increases the difficulty and time of installation but may also lead to insecure screw installation due to the inconvenience, affecting the overall stability and safety of the lamp, and reducing installation efficiency and product quality.

[0007] In summary, the existing rotating lamp structure, which uses metal brackets for fixing and screws with limiting grooves for positioning, suffers from problems such as easily affected rotational smoothness, structural limitations and unsightly appearance, and inconvenient installation and operation in actual use. It is urgent to improve and optimize it to enhance the performance of the lamp and the user experience. Summary of the Invention

[0010] Furthermore, the support device consists of two U-shaped brackets stacked together, with one side of each bracket opening to form a chamber, and the open ends of the two brackets being closed and stacked together.

[0011] Furthermore, the first protrusion is connected to the side wall of the lamp body through a first rotating fitting part. The first rotating fitting part consists of a first fitting post and a first connecting post. The first fitting post and the first connecting post are concentrically arranged. The outer diameter of the first fitting post is larger than the outer diameter of the first connecting post, and the height of the first connecting post is larger than the height of the first fitting post. The first protrusion is disposed on the first fitting post and is flush with the first connecting post.

[0012] Furthermore, a second rotating engagement portion is provided on the side of the lamp body opposite to the first rotating engagement portion, and a rotating motor is provided on the side of the lamp body near the second rotating engagement portion, the rotating motor driving the lamp body and the support device to rotate relative to each other.

[0013] Furthermore, the rotary motor is fixedly connected to the lamp body, and the rotary motor is provided with a rotatable irregular shaft. The support device is connected to the rotary motor through a fixing plate, and the fixing plate is provided with an irregular hole that matches the irregular shaft.

[0014] Furthermore, the fixing piece is L-shaped, and the supporting device consists of a first bracket and a second bracket. One end of the fixing piece is horizontally fixed by the first bracket, and the other end of the fixing piece is vertically fixed by the second bracket.

[0015] Furthermore, the first bracket has a first fixing platform in the cavity near the second rotating fixing part, and the second bracket has a first positioning groove in the cavity near the second rotating fixing part. One end of the fixing piece is connected to the first fixing platform, and the other end is inserted into the first positioning groove.

[0016] Furthermore, a second fixing platform is provided on the inner wall of the lamp body near the rotating motor. The rotating motor is fixed to the lamp body through the second fixing platform, and a nut positioning groove is provided on the second fixing platform.

[0017] Furthermore, the support device has four mounting holes on its horizontal side for fixing the support device. The four mounting holes are arranged at the four corners of the horizontal side of the support device. The distance between two mounting holes along the length of the horizontal side of the support device is greater than the length of the lamp body, and the distance between two mounting holes along the width of the horizontal side of the support device is greater than the height of the lamp body.

[0018] Furthermore, the cavity of the support device is also equipped with an ultrasonic module, which is electrically connected to the power module inside the lamp body.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a lamp structure that facilitates rotation and installation. It eliminates the need for traditional slot-type limiting structures by using a first protrusion in the rotating part of the lamp body to engage with a second protrusion in the first rotating fixing part of the support device for positioning. This non-slot design eliminates gaps that could accommodate debris. When the first and second protrusions engage to achieve positioning, it prevents leaves, branches, etc., from getting stuck, ensuring smooth rotation of the lamp body and stable adjustment of the lamp body angle, thus preventing jamming and ensuring smooth rotation. The support device adopts a "U"-shaped structure with an internal cavity. The design of two "U"-shaped brackets stacked together increases the internal space. Components such as wiring and control modules can be placed inside the cavity. Compared to the shortcomings of traditional hardware brackets that lack storage space, this not only optimizes the internal structural layout of the lamp but also hides internal components, improving the overall aesthetics of the lamp. Four mounting holes on the horizontal side of the support device are located at the four corners of the horizontal side, and the hole spacing along the length and width of the horizontal side is greater than the length and height of the lamp body, respectively. During installation, the lamp body will not interfere with the fixing screws, eliminating the need for installers to operate in confined spaces, thus reducing installation difficulty, shortening installation time, improving installation efficiency and screw installation firmness, and ensuring the overall stability and safety of the lamp. The support device cavity is equipped with an ultrasonic module that is electrically connected to the power module, enabling functions such as automatic bird deterrence, preventing birds from landing on the lamp and affecting the rotation of the lamp body, meeting diverse user needs, and enhancing the lamp's intelligence level and market competitiveness.

[0053] The following describes in detail, with reference to the accompanying drawings, the lamp structure according to an embodiment of the present invention, which is convenient for rotation and installation.

[0054] A lamp structure for easy rotation and installation according to an embodiment of the present invention includes: a lamp body 1, the bottom of which emits light for illumination; rotating mating parts extending outward along their respective sidewalls are provided on opposite sides of the lamp body 1, the axes of the two rotating mating parts overlapping to form the rotation axis of the lamp body 1; at least one rotating mating part has a first protrusion 11 extending outward from its sidewall along its radial direction; and a support device 2, which has a U-shaped structure consisting of one horizontal side and two vertical sides, and a cavity 20 formed inside the support device 2. The inner sides of the two vertical sides are respectively provided with a first rotating fixing part 21A and a second rotating fixing part 21B at positions opposite to the rotating fitting part of the lamp body 1. The axis of the first rotating fixing part 21A and the axis of the second rotating fixing part 21B coincide with the axis of rotation of the lamp body 1. The first rotating fixing part 21A, which cooperates with the first protrusion 11, is provided with a second protrusion 22 along its radial direction. The second protrusion 22 is located on the side of the first rotating fixing part 21A near the cavity 20. When the first protrusion 11 contacts the second protrusion 22, it can prevent the lamp body 1 and the support device 2 from rotating further.

[0055] In other words, this utility model provides a convenient rotating and installing lamp structure, comprising a lamp body 1 and a support device 2. As shown in Figures 2, 3, and 4, the lamp body 1 houses a light source 7, preferably an LED light source. A light-transmitting plate 5 is located at the bottom of the lamp body 1, and a reflector 6 is positioned between the light source 7 and the light-transmitting plate 5. The reflector 6 reflects and directs the light emitted by the light source 7 to improve lighting efficiency and alter light distribution characteristics. The light-transmitting plate 5 effectively prevents external dust, debris, and moisture from entering the reflector, thus protecting the reflector and its internal optical components (such as the LED light source and the reflector itself) from contamination and damage. A solar panel 8 is located at the top of the lamp body 1, absorbing sunlight for energy conversion. A battery compartment 18 and a controller (not shown in the figures) are also located inside the lamp body 1. A battery 9 is located inside the battery compartment 18. The solar panel 8, battery 9, controller, and light source 7 are electrically connected. The solar panel 8 converts collected solar energy into electrical energy and stores it in the battery 9. The electrical energy from the battery 9 is then used to supply current to the light source 7 via the controller.

[0056] As shown in Figures 6 to 8, the left and right sides of the lamp body 1 are provided with rotating mating parts extending outward along their respective side walls. As shown in Figure 6, the left side is the first rotating mating part 12A and the right side is the second rotating mating part 12B. The two rotating mating parts are designed to be coaxial, that is, the axes of the two rotating mating parts overlap to form the rotation axis of the lamp body 1, ensuring the axial stability of the lamp body when it rotates. At least one of the rotating mating parts is provided with a first protrusion 11 extending outward from the side wall along its radial direction. The first protrusion 11 acts as an active limiting component and moves along the rotation trajectory of the lamp body 1.

[0057] The lamp body 1 is connected to the support device 2 via two rotating mating parts on the left and right, as shown in Figures 11 and 12. The support device 2 has a U-shaped structure consisting of one horizontal side and two vertical sides. A cavity 20 is formed inside the support device 2. Compared with traditional hardware brackets, the cavity 20 can accommodate more components and can hide the rotating structure of the lamp body 1 and the support device 2 within the cavity 20, preventing leaves, branches, etc., from getting stuck and ensuring smooth rotation of the lamp body. A first rotating fixing part 21A and a second rotating fixing part 21B are respectively provided on the inner sides of the two vertical sides of the support device 2, opposite to the rotating mating parts of the lamp body 1. The axes of the first rotating fixing part 21A and the second rotating fixing part 21B coincide with the rotation axis of the lamp body 1; that is, the first rotating fixing part 21A, the second rotating fixing part 21B, the first rotating mating part 12A, and the second rotating mating part 12B are coaxially designed. The first rotating fixing part 21A, which cooperates with the first protrusion 11, has a second protrusion 22 radially arranged on the side of the first rotating fixing part 21A near the chamber 20. When the first protrusion 11 contacts the second protrusion 22, it can prevent the lamp body 1 and the support device 2 from rotating further. When the lamp body 1 rotates around the rotation axis, the first protrusion 11 rotates with the lamp body 1 until the first protrusion 11 contacts the second protrusion 22. The two abut against each other to form a mechanical limit, preventing the lamp body from rotating further. Since the limiting structure is located on the side near the chamber 20, and the limiting structure formed by the first protrusion 11 and the second protrusion 22 is a direct contact between the protrusions, the entire rotation process is completed within the chamber 20, which can prevent debris such as leaves, branches, and bird droppings from getting stuck in the limiting structure. Furthermore, the contact surface of the first protrusion 11 and the second protrusion 22 is designed as a slope structure, and the slope angle is preferably 3° to 8° to avoid hard collision between the two. Furthermore, two second protrusions 22 can be provided on the first rotating fixing part 21A of the support device 2. The first protrusion 11 rotates between the two second protrusions 22, thereby limiting the first protrusion 11 in both positive and negative directions. The specific limiting angle can be selected according to the designed rotation angle range.

[0058] According to this utility model, a lamp structure that facilitates rotation and installation utilizes a first protrusion 11 of the rotating mating part of the lamp body 1 and a second protrusion 22 of the first rotating fixing part 21A in the support device 2 for positioning, thus eliminating the need for a traditional slot-type positioning structure. This non-slot design eliminates gaps that could accommodate debris. When the first protrusion 11 and the second protrusion 22 contact to achieve positioning, it prevents leaves, branches, etc., from getting stuck, ensuring smooth rotation of the lamp body and stable adjustment of the lamp body angle, achieving the purpose of preventing jamming and ensuring smooth rotation. The support device 2 adopts a "U"-shaped structure and forms an internal cavity 20, increasing the internal space. Components such as wiring and control modules can be placed inside the cavity 20. Compared with the shortcomings of traditional hardware brackets that lack storage space, this not only optimizes the internal structural layout of the lamp but also hides internal components, improving the overall aesthetics of the lamp.

[0059] According to one embodiment of the present invention, the support device 2 consists of two U-shaped brackets stacked together, with one side of the bracket opening to form a chamber 20, and the open ends of the two brackets being closed and stacked together.

[0060] In other words, as shown in Figures 9 to 12, to facilitate processing and accommodate more components within the chamber 20, the support device 20 is designed as two U-shaped brackets stacked together. One side of each bracket opens to form the chamber 20, and the open ends of the two brackets are closed and stacked together. The two brackets can be connected using a snap-fit ​​mechanism or screws. As shown in Figure 12, the two brackets are connected by screws. For aesthetic purposes, a retaining ring can be added to the screw opening. The stacked bracket design makes the structure of the support device 2 more stable, while also facilitating the concealment of internal components, improving appearance, and simplifying production.

[0061] According to one embodiment of the present invention, the first protrusion 11 is connected to the side wall of the lamp body 1 through the first rotating fitting part 12A. The first rotating fitting part 12A is composed of a first fitting post 13 and a first connecting post 14. The first fitting post 13 and the first connecting post 14 are concentrically arranged. The outer diameter of the first fitting post 13 is larger than the outer diameter of the first connecting post 14, and the height of the first connecting post 14 is larger than the height of the first fitting post 13. The first protrusion 11 is disposed on the first fitting post 13 and is flush with the first connecting post 14.

[0062] In other words, as shown in Figure 7, the first protrusion 11 is connected to the side wall of the lamp body 1 through the first rotating fitting part 12A. The first rotating fitting part 12A consists of a first fitting post 13 and a first connecting post 14, which are concentrically arranged. Correspondingly, as shown in Figures 11, 13, and 16, in use, the first rotating fitting part 12A is connected to the first rotating fixing part 21A of the support device 2, and the first fitting post 13 is covered by the first rotating fixing part 21A, forming a rigid rotating structure between the two. The outer diameter of the first fitting post 13 is larger than the outer diameter of the first connecting post 14, forming a stepped structure, which facilitates the lamp body 1 to be fitted with the first rotating fixing part 21A of the support device 2 to achieve rotation axis positioning. The height of the first connecting post 14 is greater than the height of the first fitting post 13, and the first protrusion 11 is provided on the first fitting post 13 and is flush with the first connecting post 14. The first connecting post 14 is used to enhance the strength of the first protrusion 11 and ensure that the first protrusion 11 is precisely aligned with the second protrusion 22 during rotation.

[0063] According to one embodiment of the present invention, a second rotating engagement part 12B is provided on the side of the lamp body 1 opposite to the first rotating engagement part 12A, and a rotating motor 15 is provided on the side of the lamp body 1 near the second rotating engagement part 12B. The rotating motor 15 drives the lamp body 1 and the support device 2 to rotate relative to each other.

[0064] In other words, as shown in Figures 3, 4, and 6, a second rotating engagement part 12B is provided on the side of the lamp body 1 opposite to the first rotating engagement part 12A. A rotary motor 15 is provided on the side of the lamp body 1 near the second rotating engagement part 12B. The rotary motor 15 is provided with a motor rotating shaft, which can rotate relative to the rotary motor 15. The motor rotating shaft passes through the second rotating engagement part 12B and enters the chamber 20 of the support device 2. That is, the lamp body 1 is connected to the second rotating fixing part 21B of the support device 2 through the rotary motor 15. The axis of the motor rotating shaft coincides with the rotating shaft of the lamp body 1. The rotary motor 15 drives the lamp body 1 to rotate relative to the support device 2. Through motor drive, the automatic rotation function of the lamp is realized.

[0065] According to one embodiment of the present invention, a rotary motor 15 is fixedly connected to a lamp body 1. The rotary motor 15 is provided with a rotatable irregular shaft 151. The support device 2 is connected to the rotary motor 15 through a fixing plate 16. The fixing plate 16 is provided with an irregular hole 161 that matches the irregular shaft 151.

[0066] In other words, as shown in Figures 15, 17, and 18, the rotary motor 15 is fixedly connected to the lamp body 1, and the motor's rotating shaft is a non-circular shaft 151. The support device 2 is connected to the rotary motor 15 via a fixing plate 16. The fixing plate 16 has a non-circular hole 161 that matches the non-circular shaft 151. Specifically, the non-circular shaft 151 passes through the non-circular hole 161 on the fixing plate 16 to fix the two together. Since the rotary motor 15 is fixedly connected to the lamp body 1, and the fixing plate 16 is fixedly connected to the support device 2, when the rotary motor 15 drives the non-circular shaft 151 to rotate relative to the rotary motor 15, the non-circular shaft 151 drives the fixing plate 16 to rotate together, thereby causing the support device 2 to rotate relative to the lamp body 1. Preferably, the non-circular shaft 151 and the non-circular hole 161 can be triangular, hexagonal, or strip-shaped structures as shown in Figures 17 and 18. The structure of the non-circular shaft and non-circular hole reduces the complexity of the parts, facilitates assembly, and also ensures the stability of the rotating structure and the accuracy of the transmission.

[0067] According to one embodiment of the present invention, the fixing piece 16 is L-shaped, and the support device 2 is composed of a first bracket 23 and a second bracket 24. One end of the fixing piece 16 is horizontally fixed by the first bracket 23, and the other end of the fixing piece 16 is vertically fixed by the second bracket 24.

[0068] According to one embodiment of the present invention, a first fixing platform 25 is provided in the cavity 20 of the first bracket 23 near the second rotating fixing part, and a first positioning groove 26 is provided in the cavity 20 of the second bracket 24 near the second rotating fixing part. One end of the fixing piece 16 is connected to the first fixing platform 25, and the other end is inserted into the first positioning groove 26.

[0069] In other words, as shown in Figures 14, 15, and 18, the fixing piece 16 is L-shaped. For ease of distinction, the two supports of the support device 2 are divided into a first support 23 and a second support 24. One end of the fixing piece 16 is horizontally fixed by the first support 23. Specifically, the first support 23 has a first fixing platform 25 located in the cavity 20 near the second rotating fixing part. The first fixing platform 25 has a vertically threaded hole. One end of the fixing piece 16 has a mounting hole, and the side with the mounting hole is placed horizontally on the first fixing platform 25 and fixed with screws. The other end of the fixing piece 16 is vertically fixed by the second support 24. Specifically, the second support 24 has a first positioning groove 26 located in the cavity 20 near the second rotating fixing part, and the other end of the fixing piece is inserted into the first positioning groove 26. By inserting one end of the fixing piece 16 and fixing the other end, the installation process is simplified, eliminating the need to use screws at both ends, thus reducing assembly time. Furthermore, the first fixed platform 25 and the first positioning groove 26 are both set inside the cavity 20 of the support device 2, without occupying the external space of the support device 2, thus improving the aesthetics of the lamp.

[0070] In some specific embodiments of this utility model, a second fixing platform 17 is provided on the inner wall of the lamp body 1 near the side of the rotary motor 15. The rotary motor 15 is fixed to the lamp body 1 through the second fixing platform 17, and a nut positioning groove 171 is provided on the second fixing platform 17.

[0071] In other words, as shown in Figures 6, 7, 8, and 15, to facilitate motor fixing, a second fixing platform 17 is provided on the inner wall of the lamp body 1 near the rotating motor 15. Preferably, there are two second fixing platforms 17. The rotating motor 15 is fixed to the lamp body 1 via the second fixing platforms 17. Specifically, screws pass through the second fixing platforms 17 from the outside of the lamp body 1. The rotating motor 15 has mounting holes, and hexagonal nuts are used to fix the screws inside the lamp body 1, thus fixing the rotating motor 15. To facilitate the fixing of the hexagonal nuts and save time, a nut positioning groove 171 can be provided on the second fixing platform 17 inside the lamp body 1. The positioning groove 171 matches the shape of the hexagonal nut. When installing the rotating motor 15, first align the mounting holes of the rotating motor 15 with the holes of the second fixing platform 17, then insert the nut into the nut positioning groove 171, and finally insert screws through the outside of the lamp body 1 for fixing. When fixing the screws and hexagonal nuts, no tools are needed to clamp the hexagonal nuts to complete the locking.

[0072] In some specific embodiments of this utility model, the support device 2 has four mounting holes 27 for fixing the support device 2 on its horizontal side. The four mounting holes 27 are arranged at the four corners of the horizontal side of the support device 2. The hole spacing of the two mounting holes 27 along the length of the horizontal side of the support device 2 is greater than the length of the lamp body 1, and the hole spacing of the two mounting holes 27 along the width of the horizontal side of the support device 2 is greater than the height of the lamp body 1.

[0073] In other words, as shown in Figure 19, the mounting holes 27 on the horizontal side of the support device 2 are arranged in a rectangular array. That is, the mounting holes 27 are set at the four corners of the horizontal side. The distance between two mounting holes 27 along the length of the horizontal side of the support device 2 is greater than the length of the lamp body 1, as shown in Figure 19. The distance between the two mounting holes 27 on the top or bottom side is greater than the length of the lamp body 1. The distance between two mounting holes 27 along the width of the horizontal side of the support device 2 is greater than the height of the lamp body 1, as shown in Figure 19. The distance between the two mounting holes 27 on the left or right side is greater than the height of the lamp body 1. This size design ensures that the projection of the lamp body 1 on the horizontal side of the support device 2 is completely inside the four mounting holes 27. During installation, the screwdriver can be operated from the four corners of the horizontal side of the support device 2 without obstruction, avoiding the problem of low installation efficiency due to space constraints during operation.

[0074] In some specific embodiments of this utility model, the cavity 20 of the support device 2 is also provided with an ultrasonic module 3, which is electrically connected to the power module 4 in the lamp body 1.

[0075] In other words, as shown in Figure 5, an ultrasonic module 3 is also installed in the chamber of the support device 2. The ultrasonic module 3 is electrically connected to the power module 4 inside the lamp body 1 and is also connected to the controller. The ultrasonic module 3 can emit pulse frequency ultrasonic waves with a frequency of 20-60kHz. Most birds will feel uncomfortable at this frequency and leave, thus preventing birds from staying on the lamp and affecting the rotation of the lamp body 1, or even defecating on the solar panel 8 and affecting the power generation efficiency of the solar panel 8. By installing the ultrasonic module 3 in the chamber 20, the ultrasonic module 3, the power module 4 and the controller form an independent functional unit. By emitting ultrasonic waves at regular or irregular intervals, it achieves harmless bird repellency, avoids birds causing undue interference to the lamp, and prevents bird droppings from blocking the solar panel 8.

[0076] The beneficial effects of this utility model are as follows: This utility model provides a convenient rotating and installing lamp structure. The first protrusion 11 of the rotating part of the lamp body 1 engages with the second protrusion 22 of the first rotating fixing part 21A in the support device 2 for positioning, eliminating the need for a traditional slot-type positioning structure. This non-slot design eliminates gaps that could accommodate debris. When the first protrusion 11 and the second protrusion 22 contact to achieve positioning, it prevents leaves, branches, etc., from entering and causing jamming, ensuring smooth rotation of the lamp body 1 and stable adjustment of the illumination angle, achieving the purpose of preventing jamming and ensuring smooth rotation. The support device 2 adopts a "U"-shaped structure with an internal cavity 20. The design of two "U"-shaped brackets stacked increases the internal space. Components such as wiring and control modules can be placed inside the cavity 20. Compared to the shortcomings of traditional hardware brackets that lack storage space, this not only optimizes the internal structural layout of the lamp but also hides internal components, improving the overall aesthetics of the lamp. The four mounting holes 27 on the horizontal side of the support device 2 are located at the four corners of the horizontal side, and the hole spacing along the length and width of the horizontal side is greater than the length and height of the lamp body 1, respectively. During installation, the lamp body 1 will not interfere with the fixing screws, eliminating the need for installers to operate in confined spaces, thus reducing installation difficulty, shortening installation time, improving installation efficiency and screw installation firmness, and ensuring the overall stability and safety of the lamp. The support device 2, with its chamber 20 containing an ultrasonic module 3 electrically connected to the power module 4, enables automatic bird deterrence and other functions, preventing birds from landing on the lamp and affecting the rotation of the lamp body 1. This meets diverse user needs and enhances the lamp's intelligence level and market competitiveness.

[0077] Of course, other structures and working principles of lamps that facilitate rotation and installation are understandable and achievable for those skilled in the art, and will not be described in detail in this utility model.
