Description

Technical Field

[0001] This application relates to the field of support equipment technology, and in particular to a support frame and lighting device. Background Technology

[0002] Existing support frames can quickly switch multiple support legs from a folded state to an unfolded state and are widely used. However, since the height of the support legs of existing support frames is usually not convenient to adjust individually, when the support frame is used in environments with uneven ground, tabletops or walls, the support frame often has difficulty maintaining balance and is prone to wobbling, resulting in poor stability of the support frame. Utility Model Content

[0003] Therefore, it is necessary to provide a support frame and lighting device with high stability.

[0004] A support frame, comprising:

[0005] main body;

[0006] Multiple support legs, each with a first end rotatably connected to the main body, the multiple support legs rotating relative to the main body to achieve unfolding and folding; and

[0007] A magnetic foot pad assembly is provided at the second end of at least one of the support feet. The magnetic foot pad assembly includes a protective shell and a magnet. The magnet is disposed inside the protective shell, and the angle of the magnet relative to the support foot is adjustable.

[0008] In one embodiment, the protective shell is rotatably disposed at the second end of the support foot, and the angle of the magnet relative to the support foot is adjustable due to the protective shell.

[0009] In one embodiment, the magnetic foot pad assembly further includes a rotating shaft connecting the protective shell and a second end of the support foot, the protective shell being rotatable relative to the support foot about the axial direction of the rotating shaft.

[0010] In one embodiment, the protective shell is a flexible shell, and the angle of the magnet relative to the supporting foot is adjustable by the flexible deformation of the protective shell.

[0011] In one embodiment, the second end of each of the support feet is provided with the magnetic foot pad assembly.

[0012] In one embodiment, there are two support legs. When the two support legs are in a folded state, the magnets provided at the second ends of the two support legs can attract each other to maintain the folded state of the two support legs.

[0013] In one embodiment, the protective shell covers the magnet's sides and top, and the bottom of the protective shell has a clearance opening through which the bottom surface of the magnet is exposed to the outside, and the bottom surface of the magnet constitutes the magnet's adsorption surface.

[0014] In one embodiment, the protective shell is provided with a first fixing hole, the magnet is provided with a second fixing hole, and the magnetic foot pad assembly further includes a fastener that passes through the first fixing hole and the second fixing hole in sequence to fix the protective shell and the magnet.

[0015] In one embodiment, both the magnet and the protective shell have rectangular cross-sectional shapes, and the outer contour of the magnet matches the inner contour of the protective shell.

[0016] A lighting device includes: a lighting component and the aforementioned support frame, wherein the lighting component is mounted on the top of the main body.

[0017] This utility model has at least the following beneficial effects:

[0018] The aforementioned support frame has multiple support legs that can rotate away from the main body to unfold, increasing the radius of the ground support point and effectively enhancing the stability of the support frame when standing, allowing it to stand stably even when tilted. Conversely, multiple support legs can rotate towards the main body to fold, making the support frame smaller and easier to carry when folded.

[0019] Furthermore, in this design, at least one support foot is equipped with a magnetic foot pad assembly at its second end. This assembly includes a protective shell and a magnet, with the magnet housed within the protective shell. The angle of the magnet relative to the support foot is adjustable. This design allows the support frame to be used on uneven surfaces such as floors, tabletops, or walls. The adjustable magnet angle ensures a tight seal between the magnet and the object being attracted, thus reinforcing the support frame and improving its stability. Simultaneously, the change in magnet angle leads to a change in the height of the support foot. Adjusting the height of at least one support foot makes the support frame more stable, preventing wobbling. Additionally, by placing the magnet within the protective shell, direct exposure to air is prevented, protecting it from environmental corrosion and extending its lifespan.

[0029] 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.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the term "and / or" throughout the text includes three solutions; taking A and / or B as an example, it includes technical solution A, technical solution B, and a technical solution that simultaneously satisfies A and B. Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] like Figure 1 and Figure 2 As shown, this application provides a support frame 200, which can be placed on the ground or attached to an object (such as a metal object). The support frame 200 can also be attached to higher areas such as metal ceilings to achieve different usage scenarios, which are not limited here.

[0033] The support frame 200 includes a main body 210, multiple support legs 230, and a magnetic foot pad assembly 250. The top of the main body 210 can be used to mount a load device, which may be, but is not limited to, a lighting assembly 100. The first end of each support leg 230 is rotatably connected to the main body 210. The multiple support legs 230 rotate relative to the main body 210 to achieve unfolding and folding. The second end of at least one support leg 230 is provided with a magnetic foot pad assembly 250. The magnetic foot pad assembly 250 includes a protective shell 251 and a magnet 252. The magnet 252 is disposed inside the protective shell 251, and the angle of the magnet 252 relative to the support leg 230 is adjustable.

[0034] The aforementioned support frame 200 has multiple support legs 230 that can rotate away from the main body 210 to unfold, thereby increasing the radius of the ground support point and effectively increasing the stability of the support frame 200 when standing, allowing it to stand stably even when tilted. Correspondingly, the multiple support legs 230 can rotate towards the main body 210 to fold, making the support frame 200 smaller and easier to carry in the folded state.

[0035] Furthermore, in this design, at least one support foot 230 has a magnetic foot pad assembly 250 at its second end. The magnetic foot pad assembly 250 includes a protective shell 251 and a magnet 252, which is housed within the protective shell 251. The angle of the magnet 252 relative to the support foot 230 is adjustable. This design ensures that when the support frame 200 is used on uneven surfaces such as floors, tabletops, or walls, the magnet 252 can freely adjust its adsorption angle, guaranteeing a tight fit between the magnet 252 and the object being adsorbed, thus strengthening the support frame 200 and improving its stability. Simultaneously, the change in the angle of the magnet 252 causes a change in the height of the support foot 230. Adjusting the height of at least one support foot 230 makes the support frame 200 more stable, preventing it from wobbling. Additionally, by housing the magnet 252 within the protective shell 251, direct exposure to air is prevented, protecting it from environmental corrosion and extending its lifespan.

[0036] like Figure 1 As shown, specifically, each support foot 230 is provided with a magnetic foot pad assembly 250 at its second end. This allows the support frame 200 to be more stable by adjusting the height of multiple support feet 230 at the same time, preventing the support frame 200 from wobbling.

[0037] Although the accompanying drawings show three support legs, in other embodiments, there are two support legs. In this case, when the two support legs 230 are in a folded state, the magnets 252 provided at the second ends of the two support legs 230 can attract each other to maintain the folded state of the two support legs 230.

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the protective shell 251 covers the four sides and top of the magnet 252, and the bottom of the protective shell 251 has a relief opening 254. The bottom surface of the magnet 252 is exposed to the outside through the relief opening 254. The bottom surface of the magnet 252 constitutes the adsorption surface of the magnet 252, so that the magnet 252 can fit tightly with the adsorbed object to ensure the adsorption force. The bottom surface of the magnet 252 is higher than the bottom surface of the protective shell 251, that is, the magnet 252 is completely built into the protective shell 251. It can be understood that in other embodiments, the magnet 252 may be partially exposed outside the protective shell 251.

[0039] like Figure 3As shown, in one embodiment, the protective shell 251 is provided with a first fixing hole 255, the magnet 252 is provided with a second fixing hole 256, and the magnetic foot pad assembly 250 further includes a fastener. The fastener passes through the first fixing hole 255 and the second fixing hole 256 in sequence to fix the protective shell 251 and the magnet 252. Specifically, the first fixing hole 255 is located at the top center of the protective shell 251 and passes through the top of the protective shell 251. The second fixing hole 256 is located at the middle of the magnet 252 and extends along the thickness direction of the magnet 252, passing through both the bottom and top of the magnet 252. The first fixing hole 255 and the second fixing hole 256 are coaxially arranged. The fastener may be, but is not limited to, a threaded fastener.

[0040] In one embodiment, both the magnet 252 and the protective shell 251 have rectangular cross-sectional shapes, and the outer contour of the magnet 252 matches the inner contour of the protective shell 251 so that the protective shell 251 and the magnet 252 can form a tight fit.

[0041] like Figure 2 As shown, optionally, the protective shell 251 is rotatably disposed at the second end of the support foot 230. The angle of the protective shell 251 relative to the support foot 230 is adjustable, that is, the rotation of the protective shell 251 drives the rotation of the magnet 252, thereby realizing the angle adjustment of the magnet 252. The magnetic foot pad assembly 250 also includes a rotating shaft 253, which connects the protective shell 251 and the second end of the support foot 230. The protective shell 251 can rotate relative to the support foot 230 about the axial direction of the rotating shaft 253. In one embodiment, a first connecting hole is provided on the side wall of the protective shell 251, and a second connecting hole is provided at the second end of the support foot 230. The rotating shaft 253 passes through the first connecting hole and the second connecting hole, so that the protective shell 251 can rotate relative to the support foot 230 about the axial direction of the rotating shaft 253. It should be understood that in other embodiments, the first connecting hole can be omitted. In this case, the rotating shaft 252 can be fixedly connected to the protective shell 251 and simultaneously pass through the second connecting hole. Alternatively, the second connecting hole can be omitted. In this case, the rotating shaft 252 can be fixedly connected to the second end of the support foot 230 and simultaneously pass through the first connecting hole.

[0042] Optionally, the protective shell 251 is a flexible shell, and the angle of the magnet 252 relative to the support foot 230 can be adjusted by the flexible deformation of the protective shell 251. With this configuration, the protective shell 251 does not need to rely on the rotating shaft 253 to achieve a rotational connection with the support foot 230, and the magnet 252 can also freely adjust its angle under the flexible deformation of the flexible shell.

[0043] Alternatively, magnet 252 can be a powerful magnet. The object to be attracted can also be a substance that can be attracted by a magnet, such as iron, cobalt, nickel and their alloys.

[0044] Specifically, in this embodiment, the number of support legs 230 can be three. When the support legs 230 are in the unfolded state, the three support legs 230 form a triangular structure, giving the support frame 200 high stability and strength. It is understood that in other embodiments, the number of support legs 230 can be two or four or more, and this is not limited here.

[0045] like Figure 1 and Figure 4 As shown, to further improve the ease of unfolding and folding of the multiple support legs 230, the support frame 200 also includes a slider 220, which is slidably sleeved on the outside of the main body 210; the first end of each support leg 230 is rotatably connected to the slider 220; when the support leg 230 moves along the axial direction of the main body 210 and toward the bottom end of the main body 210 following the slider 220, the support leg 230 can rotate away from the main body 210 and unfold; when the support leg 230 moves along the axial direction of the main body 210 and toward the top end of the main body 210 following the slider 220, the support leg 230 can rotate toward the main body 210 and fold.

[0046] In the aforementioned support frame 200, as the support leg 230 moves along the axial direction of the main body 210 towards the bottom end of the main body 210 following the slider 220, the support leg 230 can rotate away from the main body 210 and unfold, thereby increasing the radius of the ground support point and effectively increasing the stability of the support frame 200 when standing, allowing the support frame 200 to stand stably even when tilted. Correspondingly, as the support leg 230 moves along the axial direction of the main body 210 towards the top end of the main body 210 following the slider 220, the support leg 230 can rotate towards the main body 210 and fold. The unfolding and folding of the support leg 230 is achieved by moving the slider 220. In the folded state, the support frame 200 is smaller and easier to carry. It should be noted that using the slider 220 to unfold and fold the support leg 230 is only one possible implementation method and is not the only one.

[0047] like Figure 1 and Figure 4 As shown, the support frame 200 further includes multiple support rods 240. The first end of each support rod 240 is rotatably connected to the middle of the support foot 230, and the second end of each support rod 240 is rotatably connected to the bottom end of the main body 210. Each support rod 240 corresponds to one of the multiple support feet 230. By configuring the support rods 240, a triangular structure is formed between the sliding member 220, the support foot 230, and the support rods 240, resulting in high stability and strength.

[0048] like Figure 1 and Figure 4 As shown, the support frame 200 further includes a telescopic member 260, which has a fixed end 262 and a free end 264 arranged opposite to each other along its axial direction. The fixed end 262 of the telescopic member 260 is connected to the top of the main body 210, and the free end 264 of the telescopic member 260 can move closer to and further away from the main body 210 relative to the fixed end 262 of the telescopic member 260.

[0049] In practical use, users can appropriately increase the length of the telescopic component 260 according to different usage scenarios to increase the height of the support frame 200. When storing the support frame 200, the telescopic component 260 can be retracted. Therefore, the support frame 200 can achieve a wide range of height adjustment through the telescopic component 260, which facilitates the expansion of the use range and portability of the support frame 200.

[0050] In this embodiment, the free end 264 of the telescopic member 260 is the end that can be extended or retracted, and the fixed end 262 of the telescopic member 260 is the end that fixes the telescopic member 260. When the telescopic member 260 is in the retracted state, the free end 264 of the telescopic member 260 is stored inside the fixed end 262 of the telescopic member 260; and when the free end 264 of the telescopic member 260 is pulled out from the fixed end 262 of the telescopic member 260, the telescopic member 260 is in the extended state. Of course, in this embodiment, the telescopic member 260 may also have a fully extended or partially extended state, etc., which can be set according to the actual use scenario of the support frame 200, and is not limited here.

[0051] Specifically, a load device (e.g., lighting assembly 100) is mounted on the free end 264 of the telescopic member 260. The load device can move away from the fixed end 262 of the telescopic member 260 as the free end 264 extends, thus increasing the height of the load device. Alternatively, the load device can move towards the fixed end 262 of the telescopic member 260 as the free end 264 retracts, thus decreasing the height of the load device. The telescopic member 260 can adapt to different height usage scenarios, and its length can be appropriately increased depending on the usage scenario. When storing the load device and the support frame 200, the telescopic member 260 can be retracted, allowing the load device and other structures of the support frame 200 to be stored together, thereby reducing space occupation and facilitating portability.

[0052] Furthermore, the fixed end 262 of the telescopic member 260 is rotatably connected to the top of the main body 210. At this time, the fixed end 262 of the telescopic member 260 can rotate relative to the main body 210. With this configuration, the angle of the telescopic member 260 can be adjusted by rotating the fixed end 262 of the telescopic member 260, which facilitates the expansion of the application range and portability of the support frame 200.

[0053] Specifically, while the height of the load device (e.g., lighting component 100) can be adjusted by means of the telescopic member 260, the angle of the load device can also be adjusted by means of the rotation of the fixed end 262 of the telescopic member 260 relative to the main body 210, so as to achieve a wider range of angle adjustment of the load device and thus improve the user experience.

[0054] Furthermore, to achieve the extension and retraction of the telescopic member 260, the telescopic member 260 includes multiple telescopic rods that are sequentially sleeved together. The inner diameter of the multiple telescopic rods decreases sequentially from the fixed end 262 of the telescopic member 260 to the free end 264 of the telescopic member 260. That is, when the telescopic member 260 is in the extended state, the inner diameter of the multiple telescopic rods gradually decreases from the end of the telescopic member 260 closest to the main body 210 to the end of the telescopic member 260 furthest from the main body 210. In other words, the telescopic rod closest to the main body 210 has the largest inner diameter, so that the other telescopic rods can be accommodated within the telescopic rod with the largest inner diameter.

[0055] Optionally, the telescopic pole is made of aluminum. Alternatively, the telescopic pole can also be made of other materials, such as aluminum alloy, copper, iron, composite materials, etc., and there is no limitation on this.

[0056] like Figure 1 and Figure 4 As shown, this application also provides a lighting device 10, which includes a lighting component 100 and the aforementioned support frame 200. The lighting component 100 is mounted on the top of the main body 210. Optionally, the lighting component 100 is rotatably mounted on the top of the main body 210 to adjust the light emission angle of the lighting component 100, thereby allowing the light emission angle of the lighting component 100 to be corrected within a certain range.

[0057] like Figure 5 and Figure 6 As shown, the lighting assembly 100 includes a light-emitting component 110 and a connector 120. The light-emitting component 110 is provided with a rotating cavity 134. The connector 120 includes a first connecting portion 123 and a second connecting portion 122. The first connecting portion 123 is rotatably connected to the rotating cavity 134 to adjust the light-emitting angle of the light-emitting component 110 relative to the connector 120. The first connecting portion 123 is provided with a gap 121. The first connecting portion 123 is pressed into the rotating cavity 134. The gap 121 is used to allow the connector 120 to deform and generate an elastic force when it is pressed. The second connecting portion 122 is connected to the first connecting portion 123 and to the support frame 200. Specifically, the second connecting portion 122 is connected to the top of the main body 210. More specifically, the second connecting portion 122 is inserted into the free end 264 of the telescopic member 260.

[0058] The lighting assembly 100 provided in this application includes a light-emitting component 110 with a rotating cavity 134 and a connector 120 including a first connecting portion 123 and a second connecting portion 122. The first connecting portion 123 is rotatably connected within the rotating cavity 134 to adjust the light-emitting angle of the light-emitting component 110 relative to the connector 120, thereby allowing the light-emitting angle of the light-emitting component 110 to be corrected within a certain range. Furthermore, in this solution, since the first connecting portion 123 is pressed within the rotating cavity 134 and has a gap 121, the connector 120 will deform after being pressed by the light-emitting component 110. At this time, the deformation space left by the gap 121 of the connector 120 allows the size of the connector 120 to change with the pressure. Since the connector 120 with the gap 121 can generate elastic force when deformed under force, it acts on the light-emitting component 110, which increases the friction between the connector 120 and the light-emitting component 110 during the rotation of the light-emitting component 110. This ensures that the light-emitting component 110 will not be too loose and wobbly or too tight and unable to rotate during the rotation, and always maintains a balanced rotational force. At the same time, the setting of the gap 121 can also extend the service life of the connector 120.

[0059] like Figure 6 As shown, specifically, the first connecting portion 123 extends axially towards both ends, and is a hollow structure with openings at both ends. The gap 121 extends linearly from the center of the first connecting portion 123 to the axial edges of both ends of the first connecting portion 123. It can be understood that in other embodiments, the shape of the first connecting portion 123 is not limited; for example, the first connecting portion 123 can also be spherical, as long as the gap 121 on the first connecting portion 123 can cause the first connecting portion 123 to deform under force.

[0060] Furthermore, the second connecting portion 122 extends axially to both ends and is a hollow structure open at both ends. The first connecting portion 123 is perpendicularly connected to the second connecting portion 122, and the first connecting portion 123 and the second connecting portion 122 combine to form a T-shaped connector 120. The hollow structures inside the first connecting portion 123 and the second connecting portion 122 are connected, allowing conductive wires to pass through the two hollow structures and connect to the internal circuitry of the light-emitting component 110, thereby supplying power to the light-emitting component 110 or enabling control functions. The second connecting portion 122 and the first connecting portion 123 can be integrally formed.

[0061] like Figure 5 and Figure 6As shown, specifically, a rotating cavity 134 is provided inside the light-emitting component 110, and the light-emitting component 110 is also provided with a clearance notch 131. The clearance notch 131 extends from the rotating cavity 134 to the edge of the light-emitting component 110, and provides space for the second connecting portion 122 to move through the clearance notch 131, thereby making the structure of the lighting component 100 more compact. Specifically, the first connecting portion 123 is partially accommodated in the rotating cavity 134, and the clearance notch 131 provides space for the second connecting portion 122 and the first connecting portion 123 located outside the rotating cavity 134 to move through the clearance notch 131. More specifically, both ends of the first connecting portion 123 are accommodated in the rotating cavity 134, and the middle part of the first connecting portion 123 is located in the clearance notch 131. The clearance notch 131 provides space for the middle part of the first connecting portion 123 and the second connecting portion 122 to move. In other embodiments, the entire first connecting portion 123 can be accommodated within the rotating cavity 134 simultaneously. In this case, the gap 121 extends from the center of the first connecting portion 123 to both axial edges of the first connecting portion 123 to maximize the elasticity of the first connecting portion 123 when compressed. It should be noted that the radial dimension or thickness of the second connecting portion 122 should be smaller than that of the first connecting portion 123, and the second connecting portion 122 should be connected to the first connecting portion 123 as centrally as possible. This arrangement allows the second connecting portion 122 to swing within the clearance notch 131 at the largest possible angle range; otherwise, the second connecting portion 122 will be blocked by the window contour connecting the rotating cavity 134 and the clearance notch 131.

[0062] Based on the foregoing embodiments, the first connecting portion 123 is hollow at least at both ends and forms axial ports at both ends. The first connecting portion 123 is provided with gaps 121 at at least at both axial ends, with the gaps at both axial ends extending to their axial edges. It is understood that in other embodiments, a gap 121 may be provided at only one end of the first connecting portion 123, or the gap 121 at the end of the first connecting portion 123 may extend circumferentially rather than axially. When the gap 121 at the end of the first connecting portion 123 extends circumferentially, it is necessary to ensure that the first connecting portion 123 is subjected to continuous axial compressive force. It should be noted that the circumferentially extending gap 121 is applicable to all embodiments.

[0063] like Figure 5 and Figure 6As shown, the light-emitting component 110 includes a heat sink 130 and a light-emitting element 140. The heat sink 130 is provided with a rotating cavity 134, and the light-emitting element 140 is disposed on the heat sink 130. Through the contact between the light-emitting element 140 and the heat sink 130, the operating heat is effectively conducted to the heat sink 130, thereby protecting the light-emitting element 140 from damage due to high temperature. Optionally, the heat sink 130 is made of aluminum alloy. Alternatively, the heat sink 130 can also be made of other materials with good heat dissipation performance; this is not limited here.

[0064] Optionally, the light-emitting element 140 can be a light-emitting plate, and the light-emitting element 140 may include multiple LEDs connected in parallel and / or in series, and the multiple LEDs connected in parallel and / or in series together form the light-emitting surface of the light-emitting plate.

[0065] The radiator 130 has a rotating cavity 134 on its inner side and a clearance notch 131. The clearance notch 131 extends from the rotating cavity 134 to the edge of the radiator 130 and provides space for the second connecting part 122 to move through the clearance notch 131.

[0066] like Figure 5 and Figure 6 As shown, the radiator 130 includes a heat dissipation body 132 and a heat dissipation cover 133 covering the heat dissipation body 132. The heat dissipation cover 133 and the heat dissipation body 132 are arranged sequentially along the thickness direction of the radiator 130. The light-emitting element 140 is disposed on the side of the heat dissipation body 132 away from the heat dissipation cover 133. A rotating cavity 134 is provided at the joint of the heat dissipation body 132 and the heat dissipation cover 133. The first connecting part 123 is pressed between the heat dissipation cover 133 and the heat dissipation body 132. The heat dissipation cover 133 and the heat dissipation body 132 are provided with notches to jointly form the avoidance notch 131.

[0067] Specifically, a rotating cavity 134 is provided at the joint between the heat dissipation body 132 and the heat dissipation cover 133. The first connecting part 123 is squeezed into the rotating cavity 134, and the first connecting part 123 is provided with a gap 121, so that the connector 120 will deform after being squeezed by the heat dissipation body 132 and the heat dissipation cover 133. The gap 121 provides space for deformation, so that the outer dimension of the connector 120 changes with the pressure. As the connector 120 deforms under force, it generates an elastic force, which acts on the heat dissipation cover 133 and the heat dissipation body 132. This increases the friction between the connector 120 and the heat dissipation body 130 during the rotation of the heat dissipation body 130, thereby ensuring that the heat dissipation body 130 does not become too loose and wobbly or too tight and unable to rotate during the rotation, and always maintains a balanced rotational force. At the same time, the gap 121 can also extend the service life of the connector 120.

[0068] Specifically, the heat sink 133 has a first groove on the side facing the heat sink body 132, and the heat sink body 132 has a second groove on the side facing the heat sink 133. The first groove and the second groove are joined together to form a rotating cavity 134.

[0069] Specifically, the light-emitting component 110 can rotate about the first connecting portion 123 as a rotation axis, so that the light-emitting surface of the light-emitting component 110 can switch between a horizontally downward or upward orientation state and a tilted downward or tilted upward orientation state. For example, when the light-emitting surface of the light-emitting component 110 switches from a horizontally downward orientation state to a tilted downward orientation state, the clearance notch 131 provides space for the second connecting portion 122 to move, so that the second connecting portion 122 can move through the clearance notch 131. The switching between the horizontally upward orientation state and the tilted upward orientation state of the light-emitting surface of the light-emitting component 110 is similar and will not be described again. Specifically, in this embodiment, the light-emitting surface of the light-emitting component 110 is perpendicular to the thickness direction of the heat sink 130.

Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
