Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a rotation adjustment assembly, a spotlight provided with the rotation adjustment assembly, and a lighting system provided with the spotlight. Background Art

[0002] With the rise and popularity of non-main light designs, LED lights such as downlights, spotlights, track lights, and line lights are favored by consumers. Figure 1 As shown, it shows an existing spotlight 9 (some components have been omitted), which includes a rotation adjustment assembly 91, a face ring, a light source, a lens, etc.; wherein the rotation adjustment assembly 91 includes a lamp body 911, a lamp head assembly 912 and an axial bolt 913. The lamp body 911 has a cavity, and a first connecting hole is provided on the wall of the lamp body 911; the lamp head assembly 912 has a connecting arm 9121, which is inserted into the cavity from the upper side of the lamp body 911, and a second connecting hole matching the first connecting hole is provided on the connecting arm 9121, and the axial bolt 913 is connected with the first connecting hole and the second connecting hole, so that the lamp head assembly 912 can be rotated relative to the lamp body 911 through the connecting arm 9121 to adjust the lighting angle of the lamp head assembly 912; the lamp body 911 is installed on the face ring, and the face ring is used for connecting to the ceiling structure to install the spotlight 9 on the ceiling structure; the light source and the lens are both installed in the lamp head assembly 912.

[0003] However, the above-mentioned spotlight 9 has the following shortcomings: the lamp head assembly 912 and the lamp body 911 are connected only by the axial bolt 913, so that the lamp head assembly 912 can rotate relative to the lamp body 911, and it is expected that the lamp head assembly 912 can be stable at a set lighting angle; but due to the heavy weight of the lamp head assembly 912, and the light source, lens and other components are also installed in the lamp head assembly 912, therefore, when the lamp head assembly 912 is in an oblique lighting state (that is, there is an angle between the axis of the lamp head assembly 912 and the axis of the lamp body 911), the lamp head assembly 912 is not rotated relative to the lamp body 911, and .... ), the locking ability of the axial bolt 913 on the lamp holder assembly 912 will become weaker, and when the angle between the axis of the lamp holder assembly 912 and the axis of the lamp body 911 becomes larger, the locking ability of the axial bolt 913 on the lamp holder assembly 912 will become weaker, which will cause the lamp holder assembly 912 to easily shift in position after being adjusted to the set lighting angle due to the limited locking ability of the axial bolt 913, thereby causing the actual lighting effect presented by the lamp holder assembly 912 to deviate from the required lighting effect, affecting the user experience. In order to compensate for the above-mentioned deficiencies, the conventional processing method may be 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, in this way, it becomes difficult or even impossible to rotate and adjust the lamp head assembly 912 relative to the lamp body 911. Obviously, it is difficult for the spotlight 9 to ensure that the lamp head assembly 912 and the lamp body 911 rotate smoothly when controlled by external force, while ensuring that the lamp head assembly 912 is stable at the set lighting angle. Summary of the invention

[0004] In order to solve the above problems, the main purpose of the present invention is to provide a rotation adjustment assembly that allows the lamp head assembly to rotate smoothly relative to the lamp body and stably maintain a set lighting angle.

[0005] Another object of the present invention is to provide a spotlight provided with the above-mentioned rotation adjustment assembly.

[0006] Another object of the present invention is to provide a photographic system equipped with the above-mentioned spotlight.

[0007] In order to achieve the main purpose of the present invention, the present invention provides a rotation adjustment assembly, including a lamp body, a lamp holder assembly and an axial bolt, the lamp body has a cavity, the wall of the lamp body is provided with a first connecting hole, the lamp holder assembly has a connecting arm, the connecting arm is inserted into the cavity from the upper side of the lamp body, the connecting arm is provided with a second connecting hole matching the first connecting hole, and the axial bolt is connected to the first connecting hole and the second connecting hole; wherein, the rotation adjustment assembly also includes a damping member and a guide bolt, the wall of the lamp body is also provided with an arc groove, the damping member is installed at the arc groove, the connecting arm is provided with a third connecting hole at the arc groove, the guide bolt passes through the arc groove and is connected to the third connecting hole, the head of the guide bolt contacts the damping member, and the guide bolt can follow the connecting arm to move around the axial bolt in the arc groove.

[0008] As can be seen from the above, by adding a damping member and a guide bolt, the lamp holder assembly can be smoothly rotated relative to the lamp body through the axial bolt when controlled by an external force. At the same time, the guide bolt and the damping member cooperate to produce an appropriate damping feeling, thereby avoiding the difficulty of the lamp holder assembly being controlled by an external force relative to the lamp body, and ensuring that the lamp holder assembly is stably at the set lighting angle; in addition, by adjusting the contact pressure between the guide bolt and the damping member, the damping size of the lamp holder assembly rotating relative to the lamp body can be adjusted, thereby improving the flexibility of the damping adjustment, as well as improving the scope of application and practicality of the rotation adjustment assembly.

[0009] A preferred solution is that the arc groove is located on the upper side of the first connecting hole; the damping member is installed in the arc groove, the damping member has a damping surface and an arc through groove, the arc through groove extends along the extension direction of the arc groove, and the damping surface surrounds the arc through groove; the guide bolt also passes through the arc through groove, and the head of the guide bolt contacts the damping surface.

[0010] As can be seen from the above, the above design makes the installation of the damping member more convenient, and there is no need to re-mold the damping member on the lamp body, which simplifies the processing of the lamp body and the damping member, reduces the production difficulty and production cost of the lamp body and the damping member, and also makes the damping member replaceable, which is beneficial to extend the service life of the rotation adjustment assembly and ensure the reliability of the rotation adjustment assembly; in addition, it also enables the head of the bolt to have a more comprehensive contact with the damping member to ensure the damping effect.

[0011] A further solution is that the arc groove is stepped, the outer contour of the damping element matches the inner contour of the arc groove, the damping element and the arc groove are interference fit or clearance fit; and / or the damping surface is an inner inclined surface, the first opening of the inner inclined surface away from the arc groove is larger than the second opening of the inner inclined surface close to 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, through the design of the damping surface, the damping member can adapt to the head of the guide bolt with different structures, and setting the damping surface as an inner inclined surface is also conducive to hiding the head of the guide bolt; and the damping member made of rubber or silicone material, while ensuring the damping effect, is also convenient for the production and maintenance of the damping member, and is conducive to reducing production costs and maintenance costs.

[0013] Another preferred scheme 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 irradiation position and an extreme irradiation position, and along the direction of the lamp head assembly rotating from the vertical irradiation position to the extreme irradiation position, the third connecting hole is located on the upstream side of the first connecting hole; the lamp body is provided with a limiting portion on the first end side of the arc groove, and the lamp body is provided with an avoidance opening on the second end side of the arc groove, when the lamp head assembly is in the vertical irradiation position, the lamp head assembly is adjacent to the limiting portion, and the guide bolt is located at the first end of the arc groove, and when the lamp head assembly is in the extreme irradiation position, the lamp head assembly moves into the avoidance opening, and the guide bolt is located at the second end of the arc groove.

[0014] It can be seen from the above that 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 portion can ensure that the lamp head assembly can be accurately positioned in the vertical irradiation position, and the avoidance opening is used to avoid the rotation of the lamp head assembly, and at the same time can play a role in limiting and supporting the lamp head assembly to a certain extent, so that the lamp head assembly can be accurately positioned in the extreme irradiation position.

[0015] A further solution is that the rotation adjustment assembly also includes a light-shielding member, and the lamp body is arranged outside the light-shielding member; the light-shielding member has a light-shielding cover, and the wall portion of the light-shielding cover is formed with a positioning groove at the connecting arm which is concave inward toward the light-shielding cover, and the connecting arm is inserted into the positioning groove, and the positioning groove is provided with a fourth connecting hole at the second connecting hole, and the axial bolt is also connected to the fourth connecting hole; when the lamp head assembly is in the vertical irradiation position, the light-shielding cover shields the first opening formed between the lamp head assembly and the avoidance opening; when the lamp head assembly is in the extreme irradiation position, the light-shielding cover shields the second opening formed between the lamp head assembly and the limiting portion.

[0016] As can be seen from the above, the setting of the shading member enables the shading member to cover the light leaking place no matter what lighting angle the lamp head assembly is at, thereby preventing the spotlight equipped with the rotating adjustment assembly from leaking light and improving the lighting effect of the spotlight.

[0017] A further solution is that the shading cover is formed with an adjustment handle, and the adjustment handle extends toward the bottom of the lamp body; the adjustment handle is located on a side of the shading cover close to the limiting portion.

[0018] As can be seen from the above, the above design facilitates the control of the rotation of the lamp head assembly relative to the lamp body, and by designing the position of the adjustment handle, when the lamp head assembly is in a non-vertical irradiation position, the adjustment handle can still be hidden in the lamp body and avoid the adjustment handle blocking the light emitted by the light source.

[0019] Another preferred solution is that the lamp body is provided with a scale at the arc groove, and the lamp cap assembly is provided with a pointer at the scale.

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

[0021] A further solution is that a spring plunger is provided on the periphery of the lamp body, and a positioning bead of the spring plunger is located outside the cavity.

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

[0023] In order to achieve another object of the present invention, the present invention provides a spotlight, including a light source, and further including the above-mentioned rotation adjustment assembly, wherein the light source is installed in a lamp holder assembly.

[0024] As can be seen from the above, the spotlight provided with the above-mentioned rotation adjustment assembly is convenient and easy to operate when rotating and adjusting the lamp head assembly, and the lamp head assembly can be smoothly rotated relative to the lamp body. Therefore, with the cooperation of the damping member and the guide bolt, the lamp head assembly can also be stabilized at the set lighting position relative to the lamp body, thereby ensuring that the spotlight maintains the required lighting angle and guarantees the lighting effect.

[0025] In order to achieve another object of the present invention, the present invention provides a lighting system, including a control terminal, which also includes the above-mentioned spotlight; the control terminal is electrically connected to the spotlight, and / or the control terminal and the spotlight exchange information.

[0026] As can be seen from the above, the lighting system can accurately position the lighting and achieve a better lighting effect by arranging the above-mentioned spotlights, and it is also more convenient and easy to operate when adjusting the lighting angle of the spotlights.

[0039] Spotlight Example 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. Figure 4 and Figure 5 The rotation adjustment assembly 101 includes a lamp body 1, a lamp holder assembly 2, a damping member 3, a shading member 4, an axial bolt 51, a guide bolt 52 and a spring plunger 53.

[0040] Combination Figure 6 The lamp body 1 has a cavity 11, which penetrates the lamp body 1 in the height direction of the lamp body 1, and the lamp cavity is used to accommodate part of the lamp head assembly 2 and the light shielding member 4. The wall of the lamp body 1 is provided with a first connection hole 12, and the number of the first connection holes 12 is two, and the two first connection holes 12 are located at opposite sides of the cavity 11; the first connection hole 12 penetrates the wall of the lamp body 1 to communicate with the cavity 11.

[0041] In addition, an arc groove 13 is formed on the wall of the lamp body 1. The number of the arc grooves 13 is preferably two. One arc groove 13 is arranged in coordination with one first connection hole 12, that is, one arc groove 13 is arranged at one first connection hole 12. Preferably, the arc groove 13 is arranged concentrically with the first connection hole 12 that matches it; preferably, the arc groove 13 is located above the first connection hole 12, that is, the arc groove 13 is located between the first connection hole 12 and the top of the lamp body 1. This design is conducive to optimizing the overall structure of the lamp body 1 and the rotation adjustment assembly 101, and is conducive to reducing the volume of the rotation adjustment assembly 101. Furthermore, the lamp body 1 is provided with a limiting portion 14 at the first end side of the arc groove 13, and the lamp body 1 is provided with an avoidance opening 15 at the second end side of the arc groove 13.

[0042] Combination Figure 7 The lamp holder assembly 2 has a connecting arm 21, and the number of the connecting arms 21 is two, and the two connecting arms 21 correspond to the two first connecting holes 12 one by one. The connecting arm 21 is provided with a second connecting hole 211, and the second connecting hole 211 penetrates the connecting arm 21 in the axial direction of the first connecting hole 12, and the second connecting hole 211 matches the correspondingly arranged first connecting hole 12. When the lamp holder assembly 2 is assembled with the lamp body 1, the connecting arm 21 of the lamp holder assembly 2 is inserted into the cavity 11 from the upper side of the lamp body 1 until the second connecting hole 211 on the connecting arm 21 is coaxially arranged with the first connecting hole 12 on the lamp body 1, and then the first connecting hole 12 and the second connecting hole 211 are connected by the axial bolt 51, so that the lamp holder assembly 2 can 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 the outside of the lamp body 1 and is threadedly connected with the second connecting hole 211.

[0043] The lamp head assembly 2 has a vertical irradiation position relative to the lamp body 1 (such as Figure 2 as shown) and the extreme irradiation position (as Fig.11 As shown in the figure, when the lamp head assembly 2 is in the vertical irradiation position, the lamp head assembly 2 is adjacent to the limiting portion 14; when the lamp head assembly 2 is in the non-vertical irradiation position, a part of the lamp head assembly 2 can be rotated into the avoidance opening 15. Preferably, when the lamp head assembly 2 is in the extreme irradiation position, the lamp head assembly 2 can contact the lamp body 1 at the avoidance opening 15. Among them, the limiting portion 14 is used to limit the lamp head assembly 2 from continuing to move away from the avoidance opening 15, ensuring that the lamp head assembly 2 can be accurately positioned in the vertical irradiation position to meet the user's vertical irradiation requirements for the spotlight 100; the avoidance opening 15 is used to avoid the rotation of the lamp head assembly 2. In addition, the avoidance opening 15 can also play a role in limiting and supporting the lamp head assembly 2 to a certain extent, and assist the lamp head assembly 2 to be accurately positioned in the extreme irradiation position.

[0044] Combination Figure 8 and Fig. 9 , the damping member 3 is installed in the arc groove 13; wherein, the connecting arm 21 of the lamp holder assembly 2 is also provided with a third connecting hole 212 in the arc groove 13, and the guide bolt 52 passes through the arc groove 13 and is threadedly connected with the third connecting hole 212, and the head of the guide bolt 52 is in contact with the damping member 3. In addition, the guide bolt 52 can also follow the connecting arm 21 and move around the axial bolt 51 in the arc groove 13.

[0045] The head of the guide bolt 52 generates appropriate damping by contacting with the damping member 3 to prevent the lamp holder assembly 2 from rotating relative to the lamp body 1, thereby ensuring that the lamp holder assembly 2 can stably maintain the set lighting angle without being affected by the weight of the lamp holder assembly 2 and the weight of the light source, lens 102 and other components installed therein. It should be noted that the above-mentioned damping prevents the lamp holder assembly 2 from rotating relative to the lamp body 1 under the weight of the lamp holder assembly 2 and the weight of the light source, lens 102 and other components installed therein, but does not prevent the lamp holder assembly 2 from rotating relative to the lamp body 1 under the action of external force (such as human control of the movement of the lamp holder assembly 2), that is, when the lamp holder assembly 2 is controlled by external force to rotate relative to the lamp body 1, the lamp holder assembly 2 can smoothly rotate relative to the lamp body 1.

[0046] It can be seen that by providing the damping member 3 and the guide bolt 52, the lamp holder assembly 2 can be smoothly rotated relative to the lamp body 1 through the axial bolt 51 (when an external force is applied), and at the same time, the guide bolt 52 cooperates with the damping member 3 to produce an appropriate damping feeling, thereby preventing the lamp holder assembly 2 from being difficult to rotate relative to the lamp body 1 due to external force, and ensuring that the lamp holder assembly 2 is stably at the set lighting angle; in addition, by adjusting the contact pressure between the guide bolt 52 and the damping member 3, the damping size of the lamp holder assembly 2 relative to the lamp body 1 can be adjusted, thereby improving the flexibility of the damping adjustment, and improving the scope of application and practicality of the rotation adjustment assembly 101 (for example, by adjusting the damping size, it can adapt to lamp holder assemblies 2 of different weights and components of different weights installed in the lamp holder assembly 2).

[0047] In this embodiment, the damping member 3 is installed in the arc groove 13, and the damping member 3 is preferably detachably connected to the arc groove 13, so that the installation of the damping member 3 is more convenient, and there is no need to re-mold the damping member 3 on the lamp body 1, which simplifies the processing of the lamp body 1 and the damping member 3, reduces the production difficulty and production cost of the lamp body 1 and the damping member 3, and also makes the damping member 3 replaceable, which is beneficial to extend the service life of the rotation adjustment assembly 101 and ensure the reliability of the rotation adjustment assembly 101.

[0048] Preferably, the arc groove 13 is stepped, and the damping member 3 is also stepped, so that the outer contour of the damping member 3 matches the inner contour of the arc groove 13; wherein the damping member 3 and the arc groove 13 are interference fit or clearance fit. By setting the shape of the arc groove 13 and the damping member 3, the damping member 3 can be more firmly and reliably fixed in the arc groove 13 with the cooperation of the guide bolt 52, and no other additional connection structure is required to assemble the damping member 3, which simplifies the structure of the lamp body 1 and the damping member 3, and simplifies the assembly steps, which is also conducive to improving the assembly efficiency and facilitating the maintenance and replacement of the damping member 3.

[0049] The damping member 3 preferably has a damping surface 31 and an arcuate through groove 32, wherein the arcuate through groove 32 extends in the extending direction of the arcuate groove 13, and the damping surface 31 surrounds the arcuate through groove 32; when the guide bolt 52 is installed, it passes through the arcuate through groove 32 of the damping member 3 and the arcuate groove 13 on the lamp body 1, and then is threadedly connected with the third connecting hole 212 on the connecting arm 21 of the lamp holder assembly 2, and at the same time, the head of the guide bolt 52 is also in contact with the damping surface 31. This design enables the head of the bolt to make more comprehensive contact with the damping member 3 to ensure the damping effect.

[0050] In this embodiment, the damping surface 31 is an inner inclined surface, and the first opening 311 of the inner inclined surface away from the arc-shaped through groove 32 is larger than the second opening 312 of the inner inclined surface close to the arc-shaped through groove 32; of course, as other optional solutions, in other embodiments, the damping surface 31 can also be a plane. Through the design of the damping surface 31, the damping member 3 can be adapted to the head of the guide bolt 52 of different structures; wherein, when the damping surface 31 is set as an inner inclined surface, it is also beneficial to hide the head of the guide bolt 52, so as to prevent the guide bolt 52 from 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 while facilitating the production and maintenance of the damping member 3, and is beneficial to reducing production costs and maintenance costs.

[0051] It should be noted that, in other embodiments, the damping member 3 may be disposed at the arc groove 13 by: disposing the damping member 3 at the periphery of the arc groove 13, preferably, the damping member 3 is adjacent to the edge of the arc groove 13; wherein, the damping member 3 may be formed on the lamp body 1 by bonding or by a secondary injection molding process.

[0052] Furthermore, in the height direction of the lamp body 1, the first connection hole 12 and the third connection hole 212 are staggered, that is, there is an angle between the line connecting the center of the first connection hole 12 and the center of the third connection hole 212 and the height direction; and along the direction in which the lamp head assembly 2 rotates from the vertical irradiation position to the extreme irradiation position, the third connection hole 212 is located on the upstream side of the first connection hole 12, that is, the third connection hole 212 is located on the side of the first connection hole 12 close to the inside of the fiber. By setting the relative positions of the first connection hole 12 and the third connection 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. When the lamp head assembly 2 is in the vertical irradiation 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 irradiation position, the guide bolt 52 is located at the second end of the arc groove 13.

[0053] Furthermore, the lamp body 1 is provided with a scale 16 at the arc groove 13, and the lamp cap assembly 2 is provided with a pointer 22 at the scale 16, so that the user can easily know the current lighting angle position of the lamp cap assembly 2. The scale 16 is preferably directly formed on the lamp body 1 during the molding process of the lamp body 1, and the pointer 22 can be formed on the lamp cap assembly 2 through subsequent machining, or can be directly formed on the lamp cap assembly 2 during the molding process of the lamp cap assembly 2.

[0054] Combination Fig.10 and Fig.11 The lamp body 1 is sleeved on the outside of the shading member 4; wherein the shading member 4 has a shading cover 41, and the wall portion of the shading cover 41 is concavely formed with a positioning groove 411 at the connecting arm 21 toward the inside of the shading cover 41, and the number of the positioning grooves 411 is two, and the two positioning grooves 411 correspond one-to-one to 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.

[0055] When the light shield 41, the lamp body 1, the lamp holder assembly 2 and the axial bolt 51 are assembled, the connecting arm 21 is first inserted into the positioning groove 411, and then the light shield 41 is installed together with the connecting arm 21 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; then, the axial bolt 51 is passed through the first connecting hole 12 and the second connecting hole 211 from the outside of the lamp body 1 and is threadedly connected to the fourth connecting hole 412; of course, as another optional solution, the axial bolt 51 at this time may not be threadedly connected to the second connecting hole 211, or the fourth connecting hole 412 may not be threadedly connected to the axial bolt 51. In addition, the light shield 41 and the lamp holder assembly 2 can be connected through a connecting portion.

[0056] When the lamp head assembly 2 is in the vertical irradiation position, the shading cover 41 shields the first opening A formed between the lamp head assembly 2 and the avoidance opening 15; when the lamp head assembly 2 is in the extreme irradiation position, the shading cover 41 shields the second opening B formed between the lamp head assembly 2 and the limiting portion 14. It can be seen that the setting of the shading member 4 enables the shading member 4 to shield the light leaking place regardless of the lighting angle of the lamp head assembly 2, thereby preventing the spotlight 100 provided with the rotating adjustment assembly 101 from light leakage and improving the lighting effect of the spotlight 100.

[0057] In order to facilitate the control of the rotation of the lamp head assembly 2 relative to the lamp body 1, an adjustment handle 42 is formed on the light shield 41, and the adjustment handle 42 preferably extends to the bottom of the lamp body 1; preferably, the adjustment handle 42 is located on the side of the light shield 41 close to the limiting portion 14, so that when the lamp head assembly 2 is in a non-vertical irradiation position, the adjustment handle 42 can still be hidden in the lamp body 1, and the adjustment handle 42 can be prevented from blocking the light emitted by the light source, while improving the aesthetics of the spotlight 100.

[0058] The spring plunger 53 is installed on the lamp body 1. There are multiple spring plungers 53, and the multiple spring plungers 53 are distributed along the circumference of the lamp body 1; wherein, the positioning column 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 rotating adjustment assembly 101 and the face ring 103 are assembled, the rotating adjustment assembly 101 is passed through the face ring 103 (that is, the face ring 103 is sleeved on the lamp body 1 of the rotating adjustment assembly 101), so that the positioning beads of the spring plunger 53 on the lamp body 1 are engaged in the annular groove on the inner circumference of the face ring 103, and then the rotating adjustment assembly 101 is fixed on the face ring 103. The face ring 103 is used to connect with the ceiling structure so as to install the spotlight 100 on the ceiling structure. By providing the spring plunger 53 , the rotation adjustment assembly 101 can be disassembled and assembled relative to the face ring 103 , and the disassembly and assembly are convenient, thereby facilitating the repair and maintenance of the spotlight 100 .

[0059] The light source and the lens 102 are installed in the lamp holder assembly 2, so that the lamp holder assembly 2 can dissipate heat for the light source to ensure the working stability of the light source and also extend the service life of the light source.

[0060] From the above, it can be seen that the design of the rotation adjustment assembly 101 of the spotlight 100 makes it convenient and easy to operate the rotation adjustment of the lamp head assembly 2, and the lamp head assembly 2 can rotate smoothly relative to the lamp body 1; and with the cooperation of the damping member 3 and the guide bolt 52, the lamp head assembly 2 can also be stabilized at the set lighting position relative to the lamp body 1, thereby ensuring that the spotlight 100 maintains the required lighting angle and guarantees the lighting effect.

[0061] Lighting system embodiment The lighting system includes a control terminal and the spotlight described in the above spotlight embodiment; the spotlight is provided with a control unit or the light source is provided with a control module. The control terminal is connected to the control unit or the control module, and / or the control terminal exchanges information with the control unit or the control module. Among them: The control terminal may be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote controller.
