Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a rotation adjustment assembly, a spotlight equipped with the rotation adjustment assembly, and a lighting system equipped with the spotlight. Background Technology

[0002] With the rise and popularity of main light-free designs, LED lights such as downlights, spotlights, track lights, and linear lights are gaining favor among consumers. Figure 1 As shown, a conventional spotlight 9 (some components omitted) is illustrated. The spotlight 9 includes a rotation adjustment assembly 91, a face ring, a light source, a lens, etc. The rotation adjustment assembly 91 includes a lamp body 911, a lamp head assembly 912, and a central bolt 913. The lamp body 911 has a cavity, and its wall has a first connecting hole. The lamp head assembly 912 has a connecting arm 9121, which is inserted into the cavity from the top side of the lamp body 911. The connecting arm 9121 has a second connecting hole that matches the first connecting hole. The central bolt 913 connects to both the first and second connecting holes, allowing the lamp head assembly 912 to rotate relative to the lamp body 911 via the connecting arm 9121 to adjust its illumination angle. The lamp body 911 is mounted on a face ring, which is used for ceiling structure connection to mount the spotlight 9 onto the ceiling structure. The light source and lens are both installed within the lamp head assembly 912.

[0003] However, the aforementioned spotlight 9 has the following shortcomings: the lamp head assembly 912 and the lamp body 911 are only connected by a central bolt 913, allowing the lamp head assembly 912 to rotate relative to the lamp body 911, and it is expected that the lamp head assembly 912 can be stabilized at a set illumination angle; however, due to the heavy weight of the lamp head assembly 912, and the fact that components such as the light source and lens are also installed inside the lamp head assembly 912, when the lamp head assembly 912 is in an oblique illumination state (i.e., there is an angle between the axis of the lamp head assembly 912 and the axis of the lamp body 911), the illumination angle will be affected. When the lamp head assembly 912 is adjusted to the set lighting angle, the locking ability of the central bolt 913 to the lamp head assembly 912 will be weakened. Furthermore, the larger the angle between the axis of the lamp head assembly 912 and the axis of the lamp body 911, the weaker the locking ability of the central bolt 913 to the lamp head assembly 912 will be. Consequently, after the lamp head assembly 912 is adjusted to the set lighting angle, it is easy for the position to shift due to the limited locking ability of the central bolt 913. This results in a deviation between the actual lighting effect presented by the lamp head assembly 912 and the required lighting effect, affecting the user experience. To compensate for the above deficiencies, a conventional approach is to tighten the axial bolt 913 to increase the friction between the bolt and the lamp body 911 or to increase the friction between the lamp body 911 and the connecting arm 9121. However, this would make it difficult, or even impossible, for the lamp head assembly 912 to rotate relative to the lamp body 911. Obviously, the spotlight 9 cannot ensure that the lamp head assembly 912 and the lamp body 911 rotate smoothly under external force while ensuring that the lamp head assembly 912 is stably at the set illumination angle. Summary of the Invention

[0004] To solve the above problems, the main objective of this utility model is to provide a rotation adjustment assembly that allows the lamp head assembly to rotate smoothly relative to the lamp body and remain stably at a set lighting angle.

[0005] Another objective of this invention is to provide a spotlight equipped with the aforementioned rotation adjustment assembly.

[0006] Another object of this invention is to provide a photographic system equipped with the aforementioned spotlight.

[0007] To achieve the main objective of this utility model, a rotation adjustment assembly is provided, including a lamp body, a lamp head assembly, and a central bolt. The lamp body has a cavity, and a first connecting hole is provided on the wall of the lamp body. The lamp head assembly has a connecting arm, which is inserted into the cavity from the top side of the lamp body. The connecting arm has a second connecting hole that matches the first connecting hole. The central bolt is connected to the first connecting hole and the second connecting hole. The rotation adjustment assembly also includes a damping element and a guide bolt. The wall of the lamp body is also provided with an arc-shaped groove. The damping element is installed in the arc-shaped groove. The connecting arm has a third connecting hole in the arc-shaped groove. The guide bolt passes through the arc-shaped groove and connects to the third connecting hole. The head of the guide bolt contacts the damping element. The guide bolt can move around the central bolt in the arc-shaped groove with the connecting arm.

[0008] As can be seen from the above, by adding damping components and guide bolts, the lamp head assembly can smoothly rotate relative to the lamp body through the central bolt when controlled by external force. At the same time, the guide bolt and damping components work together to generate appropriate damping, which not only avoids difficulty in rotating the lamp head assembly relative to the lamp body under external force control, but also ensures that the lamp head assembly is stably positioned at the set lighting angle. In addition, by adjusting the contact pressure between the guide bolt and the damping components, the damping magnitude of the lamp head assembly's rotation relative to the lamp body can be adjusted, improving the flexibility of damping adjustment and enhancing the applicability and practicality of the rotation adjustment assembly.

[0009] In a preferred embodiment, the arcuate groove is located above the first connecting hole; the damping element is installed in the arcuate groove, the damping element has a damping surface and an arcuate through groove, the arcuate through groove extends along the extension direction of the arcuate groove, and the damping surface surrounds the arcuate through groove; the guide bolt also passes through the arcuate through groove, and the head of the guide bolt contacts the damping surface.

[0010] As can be seen from the above, the design makes the installation of the damping components more convenient, and eliminates the need to re-form the damping components onto the lamp body, simplifying the processing of the lamp body and damping components, reducing the production difficulty and cost of the lamp body and damping components, while also making the damping components replaceable, which helps to extend the service life of the rotation adjustment assembly and ensure the reliability of the rotation adjustment assembly; in addition, it also allows the bolt head to make more comprehensive contact with the damping components to ensure the damping effect.

[0011] A further option is that the arc groove is stepped, the outer contour of the damping element matches the inner contour of the arc groove, and the damping element and the arc groove are interference fit or clearance fit; and / or the damping surface is an inwardly inclined surface, the first opening at the end of the inwardly inclined surface away from the arc groove is larger than the second opening at the end of the inwardly inclined surface near the arc groove, or the damping surface is a plane; and / or the damping element is made of rubber or silicone material.

[0012] As can be seen from the above, the design of the damping surface allows the damping component to be adapted to the head of the guide bolt with different structures. Furthermore, setting the damping surface as an inwardly inclined surface is also beneficial for hiding the head of the guide bolt. The damping component made of rubber or silicone material ensures the damping effect while also facilitating the production and maintenance of the damping component, and helps to reduce production costs and maintenance costs.

[0013] Another preferred embodiment is that the first connecting hole and the third connecting hole are staggered in the height direction of the lamp body; the lamp head assembly has a vertical illumination position and an extreme illumination position, and the third connecting hole is located upstream of the first connecting hole along the direction in which the lamp head assembly rotates from the vertical illumination position to the extreme illumination position; the lamp body has a limiting part on the first end side of the arc groove, and a clearance opening on the second end side of the arc groove; when the lamp head assembly is in the vertical illumination position, the lamp head assembly is adjacent to the limiting part, and the guide bolt is located at the first end of the arc groove; when the lamp head assembly is in the extreme illumination position, the lamp head assembly moves into the clearance opening, and the guide bolt is located at the second end of the arc groove.

[0014] As can be seen from the above, by setting the relative positions of the first connecting hole and the third connecting hole, the adjustable angle range of the lamp head assembly can be increased, so that the lamp head assembly has a larger adjustable lighting range; the setting of the limiting part can ensure that the lamp head assembly can be accurately positioned in the vertical illumination position, while the clearance is used to avoid the rotation of the lamp head assembly, and at the same time, it can play a certain role in limiting and supporting the lamp head assembly, so that the lamp head assembly is accurately positioned in the extreme illumination position.

[0015] A further embodiment includes a light shield, with the lamp body fitted over the light shield. The light shield has a light cover, and the wall of the light cover has a positioning groove recessed into the light cover at the connecting arm. The connecting arm is inserted into the positioning groove, and the positioning groove has a fourth connecting hole at the second connecting hole. The shaft bolt is also connected to the fourth connecting hole. When the lamp head assembly is in the vertical illumination position, the light shield covers the first opening formed between the lamp head assembly and the clearance opening. When the lamp head assembly is in the extreme illumination position, the light shield covers the second opening formed between the lamp head assembly and the limiting part.

[0016] As can be seen from the above, the light-shielding component ensures that the light-shielding component can block the light leakage regardless of the lighting angle of the lamp head assembly, thus preventing light leakage in the spotlight equipped with this rotating adjustment assembly and improving the lighting effect of the spotlight.

[0017] A further improvement is that the light shield is molded with an adjustment handle that extends towards the bottom of the lamp body; the adjustment handle is located on the side of the light shield near the limiting part.

[0018] As can be seen from the above, the design facilitates the control of the lamp head assembly to rotate relative to the lamp body. Furthermore, the design of the adjustment handle position ensures that when the lamp head assembly is in a non-vertical illumination position, the adjustment handle can still be hidden inside the lamp body, thus preventing the adjustment handle from blocking the light emitted by the light source.

[0019] Another preferred embodiment is that the lamp body has a scale at the arc groove, and the lamp head assembly has a pointer at the scale.

[0020] As can be seen from the above, this design makes it easy for users to know the current lighting angle position of the lamp head assembly.

[0021] A further design involves installing a spring plunger on the periphery of the lamp body, with the locating bead of the spring plunger located outside the cavity.

[0022] As can be seen from the above, this design allows the rotating adjustment assembly to be disassembled and installed relative to the surface ring of the spotlight, and makes the disassembly and installation between the rotating adjustment assembly and the surface ring more convenient, thereby facilitating the maintenance and repair of the spotlight.

[0023] To achieve another objective of this utility model, this utility model provides a spotlight, including a light source, which further includes the aforementioned rotation adjustment assembly, with the light source installed within the lamp head assembly.

[0024] As can be seen from the above, the spotlight equipped with the above-mentioned rotating adjustment assembly is convenient and easy to operate when rotating and adjusting the lamp head assembly. The lamp head assembly can rotate smoothly relative to the lamp body. With the cooperation of the damping component and the guide bolt, the lamp head assembly can also be stably positioned relative to the lamp body at the set lighting position, thereby ensuring that the spotlight maintains the required lighting angle and guarantees the lighting effect.

[0025] To achieve another objective of this utility model, this utility model provides a lighting system, including a control terminal, which further includes the aforementioned spotlight; the control terminal is electrically connected to the spotlight, and / or the control terminal interacts with the spotlight.

[0026] As can be seen from the above, by setting up the aforementioned spotlights, the lighting system achieves precise lighting positions and better lighting effects, and it is also more convenient and easier to adjust the lighting angle of the spotlights. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0039] Spotlight Examples

[0040] Reference Figure 2 and Figure 3 The spotlight 100 includes a rotation adjustment assembly 101, a light source, a lens 102, and a face ring 103. Combined Figure 4 and Figure 5 The rotating adjustment assembly 101 includes a lamp body 1, a lamp head assembly 2, a damping component 3, a light shield 4, a shaft bolt 51, a guide bolt 52, and a spring plunger 53.

[0041] Combination Figure 6 The lamp body 1 has a cavity 11 that extends through the lamp body 1 along its height. The cavity is used to accommodate part of the lamp head assembly 2 and the light shield 4. The wall of the lamp body 1 has two first connecting holes 12, located on opposite sides of the cavity 11. The first connecting holes 12 penetrate the wall of the lamp body 1 to communicate with the cavity 11.

[0042] Furthermore, an arc-shaped groove 13 is formed on the wall of the lamp body 1. Preferably, there are two arc-shaped grooves 13, with one arc-shaped groove 13 cooperating with one first connecting hole 12, that is, one arc-shaped groove 13 is provided at one first connecting hole 12. Preferably, the arc-shaped groove 13 and the cooperating first connecting hole 12 are arranged concentrically; more preferably, the arc-shaped groove 13 is located on the upper side of the first connecting hole 12, that is, the arc-shaped groove 13 is located between the first connecting hole 12 and the top of the lamp body 1. This design is beneficial to optimizing the overall structure of the lamp body 1 and the rotation adjustment assembly 101, and is beneficial to reducing the volume of the rotation adjustment assembly 101. Moreover, the lamp body 1 has a limiting part 14 on the first end side of the arc-shaped groove 13, and the lamp body 1 has a clearance opening 15 on the second end side of the arc-shaped groove 13.

[0043] Combination Figure 7 The lamp head assembly 2 has two connecting arms 21, each corresponding to one of the two first connecting holes 12. Each connecting arm 21 has a second connecting hole 211 that passes through the first connecting hole 12 axially, matching the corresponding first connecting hole 12. When the lamp head assembly 2 is assembled with the lamp body 1, the connecting arm 21 of the lamp head assembly 2 is inserted into the cavity 11 from the top side of the lamp body 1 until the second connecting hole 211 on the connecting arm 21 is coaxially aligned with the first connecting hole 12 on the lamp body 1. Then, the first connecting hole 12 and the second connecting hole 211 are connected by a axial bolt 51, allowing the lamp head assembly 2 to rotate relative to the lamp body 1. Preferably, when the axial bolt 51 connects the first connecting hole 12 and the second connecting hole 211, the axial bolt 51 passes through the first connecting hole 12 from outside the lamp body 1 and is threaded into the second connecting hole 211.

[0044] Lamp head assembly 2 has a vertical illumination position relative to lamp body 1 (e.g.) Figure 2 (as shown) and extreme irradiation positions (such as...) Figure 11 As shown, when the lamp head assembly 2 is in the vertical illumination position, the lamp head assembly 2 is adjacent to the limiting part 14; when the lamp head assembly 2 is in the non-vertical illumination position, a part of the lamp head assembly 2 can rotate into the clearance opening 15. Preferably, when the lamp head assembly 2 is in the extreme illumination position, the lamp head assembly 2 can contact the lamp body 1 at the clearance opening 15. The limiting part 14 is used to restrict the lamp head assembly 2 from continuing to move away from the clearance opening 15, ensuring that the lamp head assembly 2 can be accurately positioned in the vertical illumination position to meet the user's vertical illumination requirements for the spotlight 100; the clearance opening 15 is used to avoid the rotation of the lamp head assembly 2. In addition, the clearance opening 15 can also play a certain role in limiting and supporting the lamp head assembly 2, assisting the lamp head assembly 2 in accurately positioning in the extreme illumination position.

[0045] Combination Figure 8 and Figure 9The damping component 3 is installed in the arc groove 13; the connecting arm 21 of the lamp head assembly 2 is also provided with a third connecting hole 212 in the arc groove 13. The guide bolt 52 passes through the arc groove 13 and is threadedly connected to the third connecting hole 212. The head of the guide bolt 52 contacts the damping component 3. In addition, the guide bolt 52 can also follow the connecting arm 21 to move around the axis bolt 51 in the arc groove 13.

[0046] The head of the guide bolt 52 generates appropriate damping through contact with the damping element 3 to prevent the lamp head assembly 2 from rotating relative to the lamp body 1. This ensures that the lamp head assembly 2 can be stably maintained at the set illumination angle and will not shift position due to its own weight or the weight of components such as the light source and lens 102 installed within it. It should be noted that the above-mentioned damping prevents the lamp head assembly 2 from rotating relative to the lamp body 1 under the weight of its own weight and the weight of components such as the light source and lens 102 installed within it. However, it does not prevent the lamp head assembly 2 from rotating relative to the lamp body 1 under the action of external force (such as manual control of the lamp head assembly 2). That is, when the lamp head assembly 2 is controlled by external force to rotate relative to the lamp body 1, the lamp head assembly 2 can rotate smoothly relative to the lamp body 1.

[0047] As can be seen, by setting the damping component 3 and the guide bolt 52, the lamp head assembly 2 can be smoothly rotated relative to the lamp body 1 through the shaft bolt 51 (when an external force is applied). At the same time, the guide bolt 52 and the damping component 3 cooperate to generate an appropriate damping feel, which not only avoids the difficulty of the lamp head assembly 2 rotating relative to the lamp body 1 under the control of external force, but also ensures that the lamp head assembly 2 is stably in the set lighting angle. In addition, by adjusting the contact pressure between the guide bolt 52 and the damping component 3, the damping magnitude of the rotation of the lamp head assembly 2 relative to the lamp body 1 can be adjusted, which improves the flexibility of damping adjustment and the applicability and practicality of the rotation adjustment assembly 101 (for example, by adjusting the damping magnitude, it can be adapted to lamp head assemblies 2 of different weights and components of different weights installed in the lamp head assembly 2).

[0048] In this embodiment, the damping component 3 is installed in the arc-shaped groove 13, and the damping component 3 is preferably detachably connected to the arc-shaped groove 13, which makes the installation of the damping component 3 more convenient and eliminates the need to re-form the damping component 3 onto the lamp body 1, simplifying the processing of the lamp body 1 and the damping component 3, reducing the production difficulty and production cost of the lamp body 1 and the damping component 3, and also making the damping component 3 replaceable, which is beneficial to extending the service life of the rotation adjustment assembly 101 and ensuring the reliability of the operation of the rotation adjustment assembly 101.

[0049] Preferably, the arc-shaped groove 13 is stepped, and the damping element 3 is also stepped, so that the outer contour of the damping element 3 matches the inner contour of the arc-shaped groove 13; wherein, the damping element 3 and the arc-shaped groove 13 are interference-fitted or clearance-fitted. By setting the shapes of the arc-shaped groove 13 and the damping element 3, the damping element 3 can be more firmly and reliably fixed in the arc-shaped groove 13 with the cooperation of the guide bolt 52, and there is no need to set other connecting structures for assembling the damping element 3, which simplifies the structure of the lamp body 1 and the damping element 3, simplifies the assembly steps, improves assembly efficiency, and facilitates the maintenance and replacement of the damping element 3.

[0050] The damping element 3 preferably has a damping surface 31 and an arc-shaped through groove 32. The arc-shaped through groove 32 extends along the extension direction of the arc-shaped groove 13, and the damping surface 31 surrounds the arc-shaped through groove 32. When the guide bolt 52 is installed, it passes through the arc-shaped through groove 32 of the damping element 3 and the arc-shaped groove 13 on the lamp body 1, and then is threadedly connected to the third connecting hole 212 on the connecting arm 21 of the lamp head assembly 2. At the same time, the head of the guide bolt 52 also contacts the damping surface 31. This design allows the head of the bolt to make more comprehensive contact with the damping element 3 to ensure the damping effect.

[0051] In this embodiment, the damping surface 31 is an inwardly inclined surface, and the first opening 311 at the end of the inwardly inclined surface away from the arc-shaped through groove 32 is larger than the second opening 312 at the end of the inwardly inclined surface near the arc-shaped through groove 32. Of course, as another optional solution, in other embodiments, the damping surface 31 can also be a plane. By designing the damping surface 31, the damping member 3 can be adapted to the head of the guide bolt 52 with different structures. In particular, when the damping surface 31 is set as an inwardly inclined surface, it is also beneficial to hide the head of the guide bolt 52 and avoid the guide bolt 52 interfering with the assembly of the rotation adjustment assembly 101 and the face ring 103. In addition, the damping member 3 is preferably made of rubber or silicone material, so as to ensure the damping effect, facilitate the production and maintenance of the damping member 3, and help reduce production costs and maintenance costs.

[0052] It should be noted that in other embodiments, the damping element 3 can be located at the arc groove 13 as follows: the damping element 3 is located at the periphery of the arc groove 13, and preferably, the damping element 3 is close to the edge of the arc groove 13; wherein, the damping element 3 can be formed on the lamp body 1 by bonding or by secondary injection molding process.

[0053] Furthermore, in the height direction of the lamp body 1, the first connecting hole 12 and the third connecting hole 212 are staggered, that is, the line connecting the center of the first connecting hole 12 and the center of the third connecting hole 212 forms an angle with the height direction; and along the direction of rotation of the lamp head assembly 2 from the vertical illumination position to the extreme illumination position, the third connecting hole 212 is located upstream of the first connecting hole 12, that is, the third connecting hole 212 is located on the side of the first connecting hole 12 closer to the fiber interior. By setting the relative positions of the first connecting hole 12 and the third connecting hole 212, the adjustable angle range of the lamp head assembly 2 can be increased, so that the lamp head assembly 2 has a larger adjustable lighting range. Specifically, when the lamp head assembly 2 is in the vertical illumination position, the guide bolt 52 is located at the first end of the arc groove 13; when the lamp head assembly 2 is in the extreme illumination position, the guide bolt 52 is located at the second end of the arc groove 13.

[0054] Furthermore, the lamp body 1 has a scale 16 at the arc-shaped groove 13, and the lamp head assembly 2 has a pointer 22 at the scale 16, so that the user can easily know the current lighting angle position of the lamp head assembly 2. Preferably, the scale 16 is formed directly on the lamp body 1 during the lamp body 1 forming process, and the pointer 22 can be formed on the lamp head assembly 2 through subsequent machining, or it can be formed directly on the lamp head assembly 2 during the lamp head assembly 2 forming process.

[0055] Combination Figure 10 and Figure 11 The lamp body 1 is fitted over the light shield 4; the light shield 4 has a light shield 41, and the wall of the light shield 41 is recessed into the light shield 41 at the connecting arm 21 to form a positioning groove 411. There are two positioning grooves 411, and the two positioning grooves 411 correspond one-to-one with the two connecting arms 21. In addition, a fourth connecting hole 412 is provided in the positioning groove 411 at the second connecting hole 211.

[0056] When assembling the light shield 41, lamp body 1, lamp head assembly 2, and spindle bolt 51, firstly, the connecting arm 21 is inserted into the positioning groove 411. Then, the light shield 41, along with the connecting arm 21, is installed into the cavity 11 of the lamp body 1. At this time, the connecting arm 21 is located between the lamp body 1 and the light shield 41. Next, the spindle bolt 51 is passed through the first connecting hole 12 and the second connecting hole 211 from outside the lamp body 1 and then threadedly connected to the fourth connecting hole 412. Of course, as another optional solution, the spindle bolt 51 may not be threaded to the second connecting hole 211, or the fourth connecting hole 412 may not be threaded to the spindle bolt 51. In addition, the light shield 41 and the lamp head assembly 2 can be connected through a connecting part.

[0057] When the lamp head assembly 2 is in the vertical illumination position, the light shield 41 covers the first opening A formed between the lamp head assembly 2 and the clearance opening 15; when the lamp head assembly 2 is in the extreme illumination position, the light shield 41 covers the second opening B formed between the lamp head assembly 2 and the limiting part 14. It can be seen that the light shield 4 ensures that regardless of the illumination angle of the lamp head assembly 2, it can block any light leakage, preventing light leakage from the spotlight 100 equipped with this rotary adjustment assembly 101 and improving the illumination effect of the spotlight 100.

[0058] To facilitate the control of the lamp head assembly 2 rotating relative to the lamp body 1, an adjustment handle 42 is formed in the light shield 41. The adjustment handle 42 preferably extends towards the bottom of the lamp body 1. Preferably, the adjustment handle 42 is located on the side of the light shield 41 near the limiting part 14, so that when the lamp head assembly 2 is in a non-vertical illumination position, the adjustment handle 42 can still be hidden inside the lamp body 1, and the adjustment handle 42 avoids blocking the light emitted by the light source, while improving the aesthetics of the spotlight 100.

[0059] A spring plunger 53 is mounted on the lamp body 1. Multiple spring plungers 53 are distributed circumferentially around the lamp body 1. The positioning pin 531 of the spring plunger 53 is located outside the cavity 11 of the lamp body 1. The inner circumference of the face ring 103 is provided with an annular groove. When the rotation adjustment assembly 101 is assembled with the face ring 103, the rotation adjustment assembly 101 passes through the face ring 103 (i.e., the face ring 103 is fitted onto the lamp body 1 with the rotation adjustment assembly 101), so that the positioning pin of the spring plunger 53 on the lamp body 1 engages in the annular groove on the inner circumference of the face ring 103, thereby fixing the rotation adjustment assembly 101 onto the face ring 103. The face ring 103 is used to connect with the ceiling structure to install the spotlight 100 on the ceiling structure. By setting the spring plunger 53, the rotation adjustment assembly 101 can be disassembled and installed relative to the face ring 103, and the disassembly and installation are convenient, thereby facilitating the maintenance of the spotlight 100.

[0060] The light source and lens 102 are installed inside the lamp holder assembly 2, which enables the lamp holder assembly 2 to dissipate heat from the light source, thereby ensuring the stability of the light source's operation and extending the lifespan of the light source.

[0061] In summary, the design of the rotation adjustment assembly 101 of the spotlight 100 makes it convenient and easy to operate when rotating and adjusting the lamp head assembly 2, and the lamp head assembly 2 can rotate smoothly relative to the lamp body 1; with the cooperation of the damping component 3 and the guide bolt 52, the lamp head assembly 2 can also be stably positioned relative to the lamp body 1 at the set lighting position, thereby ensuring that the spotlight 100 maintains the required lighting angle and guarantees the lighting effect.

[0062] Lighting System Examples

[0063] The lighting system includes a control terminal and the spotlights described in the above-described spotlight embodiments; the spotlights are equipped with a control unit or a control module on the light source. The control terminal is connected to the control unit or control module, and / or the control terminal interacts with the control unit or control module. Wherein:

[0064] The control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel, or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the control unit or control module.

[0065] When the control terminal is an intelligent control panel or a remote control, the control unit or control module is equipped with a first wireless communication module, and the control terminal is equipped with a second wireless communication module; the control terminal is electrically connected to the control unit or control module; and / or the first wireless communication module and the second wireless communication module exchange information.

[0066] Furthermore, the control terminal can also be a smart mobile terminal (such as a mobile phone, tablet computer, smart strapping device, etc.) or an artificial intelligence robot.
