Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically, to a rotation adjustment mechanism, a lamp equipped with the rotation adjustment mechanism, and a lighting system equipped with the lamp. Background Technology

[0002] With the rise and popularity of main light-free designs, lighting fixtures such as downlights, spotlights, track lights, and linear lights are gaining favor among consumers. Taking spotlights as an example, these fixtures typically include a fixed ring, a rotating ring, a lamp body, a light source, and optical elements. The fixed ring is used to securely connect to the ceiling, allowing the fixture to be installed. The fixed ring has a receiving position, and the rotating ring is located within this position and rotatably connected to the fixed ring. The lamp body is mounted on the rotating ring and rotates relative to the fixed ring. The light source is installed within the lamp body, and the optical elements are mounted on the rotating ring and / or the lamp body, with the light source facing the optical elements. During installation and use, the relative positions of the rotating ring and the fixed ring are often adjusted according to specific lighting requirements to achieve the desired lighting angle. Figure 1 As shown, the existing fixed ring 9 is usually equipped with an angle scale 91 and a display slot 92, while the rotating ring is equipped with a corresponding pointer at the display slot 92, so that installers or users can determine the adjusted illumination angle according to the scale indicated by the pointer.

[0003] However, when adjusting the illumination angle, the relative rotation range between the fixed ring 9 and the rotating ring is usually between 0° and 45° (when the fixed ring 9 and the rotating ring are at 0°, the first axis of the fixed ring 9 is usually parallel to the second axis of the rotating ring; when the fixed ring 9 and the rotating ring are not at 0°, the first axis and the second axis form a non-zero angle), so the range of rotation adjustment angle is not large. Furthermore, since the angle scale 91 on the fixed ring 9 is configured in a 1:1 ratio with the relative rotation range between the fixed ring 9 and the rotating ring, for example, when the relative rotation range between the fixed ring 9 and the rotating ring is between 0° and 20°, the distribution range of the angle scale 91 on the fixed ring 9 is also between 0° and 20° (see...). Figure 1 This results in a limited display area for the angle scale 91, making it difficult for installers or users to quickly, clearly, and accurately read the angle scale 91 pointed to by the pointer. This increases the difficulty of installation and adjustment for installers or users and reduces their user experience. Summary of the Invention

[0004] To address the aforementioned problems, the main objective of this invention is to provide a rotation adjustment mechanism with more easily identifiable angle scales.

[0005] Another object of the present invention is to provide a lamp having the above-mentioned rotation adjustment mechanism.

[0006] Another object of the present invention is to provide a lighting system provided with the above-mentioned lamps.

[0007] To achieve the main objective of this invention, a rotation adjustment mechanism is provided, comprising a fixed ring and a rotating ring. The fixed ring has a receiving position, a first connecting portion, a display slot, and an angle scale. The rotating ring is disposed within the receiving position and has a second connecting portion rotatably connected to the first connecting portion about a first rotation axis. The fixed ring also has a third connecting portion, with the angle scale distributed around the third connecting portion. The display slot is located between the third connecting portion and the angle scale. The rotating ring has a guide post extending parallel to the first rotation axis toward the display slot. The rotation adjustment mechanism further includes a rotating component having a fourth connecting portion, a sliding groove, and a pointer. The fourth connecting portion is rotatably connected to the third connecting portion about a second rotation axis, which is parallel to the first rotation axis. The guide post is slidably disposed within the sliding groove, and the pointer is located at the display slot.

[0008] As can be seen from the above, through the structural design of the rotating component and the cooperative structure design of the fixed ring, rotating ring and rotating component, the angle scale on the fixed ring can be enlarged according to a set ratio to increase the angle scale distribution area, thereby increasing the angle scale display area and enabling the angle scale to have an enlarged display function. This makes it easier for installers or users to identify the angle scale value pointed to by the pointer, making the design of the rotation adjustment mechanism more user-friendly, reducing the difficulty of adjusting the illumination angle of lamps equipped with this rotation adjustment mechanism for installers or users, and improving the experience of installers or users.

[0009] A further embodiment is that the rotating ring has at least a first position and a second position relative to the fixed ring; when the rotating ring is in the first position, the second connecting part, the fourth connecting part and the guide post are distributed sequentially along the height direction of the fixed ring, and the sliding groove is parallel to the height direction; when the rotating ring is in the second position, the second connecting part and the fourth connecting part are distributed along the height direction, the extension direction of the sliding groove is perpendicular to the height direction, and the guide post and the fourth connecting part are distributed along the extension direction.

[0010] As can be seen from the above, this design ensures that the rotating component closely follows the relative rotation between the fixed ring and the rotating ring, thereby enabling the pointer to accurately indicate the real-time relative angle between the rotating ring and the fixed ring. At the same time, it also prevents the rotating component from restricting the rotation of the rotating ring relative to the fixed ring.

[0011] A further proposed solution is that when the rotating ring is in the first position, the center of the guide post and the center of the fourth connecting part have a first distance in the height direction; when the rotating ring is in the second position, the center of the guide post and the center of the fourth connecting part have a second distance in the extension direction; the second distance is between 2.5 times and 4.75 times the first distance.

[0012] As can be seen from the above, this design is conducive to miniaturizing the rotating parts as much as possible, thereby optimizing the structure of the rotation adjustment mechanism and making the overall design of the rotation adjustment mechanism more reasonable and compact.

[0013] A further proposed solution is to display the through slot in an arc shape, with the first central angle of the through slot ranging from 30° to 120°; the angle scale is distributed according to the second central angle, which is equal to the first central angle, and the maximum scale value of the angle scale is between 10° and 60°.

[0014] As can be seen from the above, the structural design of the display slot, combined with the distribution design of the angle scale, enables the rotation adjustment mechanism to meet the angle adjustment needs of at least most existing lamps, and allows installers or users to quickly, clearly, and accurately read the angle scale indicated by the pointer; in addition, the structural design of the display slot can also improve the aesthetics of the rotation adjustment mechanism.

[0015] A further proposed solution is to make the actual value of each mark on the angle scale two to three times the angle value of the second central angle occupied by that mark.

[0016] As can be seen from the above, this design can optimize the magnification display function of the angle scale, so that installers or users can read the angle scale pointed to by the pointer more quickly, clearly and accurately.

[0017] A further proposed solution is to set the second distance to be 3.25 times the first distance; the first central angle to be 90°; and the actual scale value to be 2.5 times the angle value.

[0018] As can be seen from the above, this design can optimize or optimize the overall structure of the rotation adjustment mechanism, thereby making the overall structure of the rotation adjustment mechanism more optimized and compact.

[0019] A further embodiment is that the first connecting part is a countersunk hole, the second connecting part is provided with a first connecting hole that matches the countersunk hole, and the rotation adjustment mechanism also includes a first fastener, the first fastener having a first shaft segment and a first connecting segment, the first shaft segment being rotatably connected to the countersunk hole, and the first connecting segment being connected to the first connecting hole; the third connecting part is a first through hole, the fourth connecting part is a first connecting post, the first connecting post being inserted into the first through hole and rotatably connected to the first through hole, or the third connecting part is a second connecting post, the fourth connecting part is a second through hole, the second connecting post being inserted into the second through hole and rotatably connected to the second through hole, or the third connecting part is a third through hole, the fourth connecting part is provided with a second connecting hole, and the rotation adjustment mechanism also includes a second fastener, the second fastener having a second shaft segment and a second connecting segment, the second shaft segment being rotatably connected to the third through hole, and the second connecting segment being connected to the second connecting hole.

[0020] As can be seen from the above, the above design facilitates the assembly of the fixed ring, rotating ring and rotating parts.

[0021] A further proposed solution is that, when the rotating ring is in the second position, the center of the pointer is offset from the guide post relative to the line connecting the center of the second connecting part and the center of the fourth connecting part, or when the rotating ring is in the second position, the center of the pointer is located on the connecting line; the center of the second rotating shaft is located at half the width of the slide groove.

[0022] As can be seen from the above, the position design of the pointer allows it to better point to the angle scale; and the position design of the second rotation axis allows the rotating part to rotate better relative to the fixed ring, and the guide column to slide more smoothly along the slide groove.

[0023] To achieve another objective of the present invention, the present invention provides a lamp, including a lamp body, characterized in that the lamp further includes the above-mentioned rotation adjustment mechanism, and the lamp body is mounted on a rotating ring.

[0024] As can be seen from the above, lamps equipped with the aforementioned rotating adjustment mechanism are simpler and more convenient to adjust their illumination angle, and enable installers or users to read the angle scale indicated by the pointer more quickly, clearly and accurately.

[0025] To achieve another objective of the present invention, the present invention provides a lighting system including a control terminal, wherein the lighting system further includes the aforementioned lamps, the control terminal is electrically connected to the lamps, and / or the control terminal interacts with the lamps.

[0026] As can be seen from the above, by setting up the above-mentioned lamps, the lighting system makes it simpler and more convenient to adjust the illumination angle of the lamps, and enables installers or users to read the angle scale indicated by the pointer on the lamps more quickly, clearly and accurately.

[0040] Lighting Fixture Examples

[0041] Reference Figure 2 The lamp 100 includes a rotation adjustment mechanism 101, a lamp body 102, a light source, and optical elements. The rotation adjustment mechanism 101 includes a fixed ring 1, a rotating ring 2, and a rotating component 3. The fixed ring 1 and the rotating ring 2 are rotatably connected. The lamp body 102 is mounted on the rotating ring 2, allowing the lamp body 102 to rotate relative to the fixed ring 1 along with the rotating ring 2. The light source is installed inside the lamp body 102, allowing the illumination angle of the light source to be adjusted through the relative rotation between the fixed ring 1 and the rotating ring 2. The optical elements are preferably installed inside the lamp body 102 and / or on the rotating ring 2.

[0042] Combination Figure 3The fixing ring 1 has a receiving position 11, a first connecting part 12, a display through groove 13, an angle scale 14 and a third connecting part 15. The receiving position 11 penetrates the fixing ring 1 in the height direction of the fixing ring 1; the number of first connecting parts 12 is preferably two, and the two first connecting parts 12 are distributed on opposite sides of the receiving position 11 along the first rotation axis, the first rotation axis being perpendicular to the height direction of the fixing ring 1; the display through groove 13 penetrates the wall of the fixing ring 1, so that the display through groove 13 communicates with the receiving position 11; the angle scale 14 is disposed on the outer wall surface of the wall of the fixing ring 1, and the angle scale 14 and the display through groove 13 are located on the same side of the fixing ring 1; the third connecting part 15 is disposed at the display through groove 13, so that the display through groove 13 is located between the third connecting part 15 and the angle scale 14, and the angle scale 14 is distributed around the third connecting part 15. Specifically, the angle scale 14 includes multiple scale lines 141, and the multiple scale lines 141 are distributed around the third connecting part 15 with the third connecting part 15 as the center.

[0043] Combination Figure 4 The rotating ring 2 is disposed within the receiving position 11 of the fixed ring 1. The rotating ring 2 has a second connecting portion 21, the number of which is equal to the number of the first connecting portions 12 of the fixed ring 1, and one second connecting portion 21 is matched with one first connecting portion 12, so that the second connecting portion 21 can be rotatably connected to the first connecting portion 12 around the first rotation axis. Furthermore, the rotating ring 2 has a guide post 22 on the side near the display slot 13 of the fixed ring 1, the guide post 22 being parallel to the first axis and extending toward the display slot 13.

[0044] Preferably, as in this embodiment, the first connecting part 12 is a countersunk hole, and the second connecting part 21 is provided with a first connecting hole 211 that matches the countersunk hole. Furthermore, the rotation adjustment mechanism 101 also includes a first fastener, the number of which is equal to the number of the first connecting parts 12, such that one first fastener is connected to a corresponding first connecting part 12 and a second connecting part 21. The first fastener preferably has a first shaft segment and a first connecting segment. When the first fastener is connected to the first connecting part 12 and the second connecting part 21, the first shaft segment is rotatably connected to the countersunk hole, and the first connecting segment is connected to the first connecting hole 211 (e.g., by threaded connection, interference fit, adhesive fixation, etc.). The first shaft segment is preferably a stepped shaft; this design makes the assembly of the rotating ring 2 and the fixed ring 1 simpler and more convenient.

[0045] Combination Figures 5 to 7 The rotating component 3 is located within the receiving position 11 of the fixed ring 1, and the rotating component 3 is linked between the fixed ring 1 and the rotating ring 2. The rotating ring 2 is located between the display through groove 13 and the guide post 22; the rotating component 3 has a fourth connecting part 31, a sliding groove 32 and a pointer 33.

[0046] The fourth connecting part 31 is rotatably connected to the third connecting part 15 of the fixed ring 1 around the second rotation axis, wherein the second rotation axis is parallel to the first rotation axis. Preferably, as in this embodiment, the third connecting part 15 is a first through hole, and the fourth connecting part 31 is a first connecting post. The first connecting post protrudes from the rotating part 3 toward the first through hole parallel to the second rotation axis, so that when the rotating part 3 is assembled with the fixed part, the first connecting post is inserted into the first through hole, and a rotatable connection is made between the first connecting post and the first through hole; this design facilitates the assembly of the rotating part 3 and the fixed ring 1. Of course, as another optional solution, in another embodiment, the third connecting part 15 can also be a second connecting post, which protrudes from the fixed part toward the rotating part 3 parallel to the rotation axis, and the fourth connecting part 31 is a second through hole, so that when the rotating part 3 is assembled with the fixed part, the second connecting post is inserted into the second through hole, and a rotatable connection is made between the second connecting post and the second through hole. Alternatively, as another optional solution, in another embodiment, the third connecting part 15 can be provided as a third through hole or a second countersunk hole, and a second connecting hole is provided on the fourth connecting part 31 accordingly; the rotation adjustment mechanism 101 further includes a second fastener, which preferably has a second shaft segment and a second connecting segment; when the second fastener, the third connecting part 15 and the fourth connecting part 31 are connected, the second shaft end of the second fastener is placed in the third through hole and rotatably connected to the third through hole, and the second connecting segment is connected to the second connecting hole (such as threaded connection, interference fit, adhesive fixation, etc.).

[0047] The slide groove 32 and the fourth connecting part 31 are distributed on opposite sides of the rotating member 3 on the second rotation axis. When the rotating member 3 is assembled with the rotating ring 2, the rotating guide post 22 is placed in the slide groove 32 of the rotating member 3 so that the guide post 22 can slide within the slide groove 32. The pointer 33 and the slide groove 32 are distributed on opposite sides of the rotating member 3 on the second rotation axis. When the rotating member 3 is assembled with the fixed ring 1, the pointer 33 is located at the display through groove 13 of the fixed ring 1, so that the installer or user can clearly observe the pointer 33 and the scale indicated by the pointer 33.

[0048] Through the above-described structural design of the rotating component 3, and the cooperative structural design of the fixed ring 1, the rotating ring 2 and the rotating component 3, the angle scale 14 on the fixed ring 1 can be enlarged according to a set ratio to increase the distribution area of ​​the angle scale 14, thereby increasing the display area of ​​the angle scale 14 and enabling the angle scale 14 to have an enlarged display function. This makes it easier for installers or users to identify the angle scale 14 value pointed to by the pointer 33, making the design of the rotation adjustment mechanism 101 more user-friendly, reducing the difficulty for installers or users to adjust the illumination angle of the lamp 100 equipped with this rotation adjustment mechanism 101 and the installation difficulty, and improving the experience of installers or users.

[0049] The following further combines Figures 8 to 12 Provide an explanation;

[0050] The rotating ring 2 has at least a first position relative to the fixed ring 1 (e.g., Figure 7 , Figure 9 (as shown) and the second position (as shown) Figure 8 , Figure 11 (As shown). When the rotating ring 2 is in the first position, the second connecting part 21 of the rotating ring 2, the third connecting part 15 of the rotating component 3, and the guide post 22 of the rotating ring 2 are sequentially distributed along the height direction of the fixed ring 1, and the sliding groove 32 of the rotating component 3 is parallel to the height direction. When the rotating ring 2 is in the second position, the second connecting part 21 and the fourth connecting part 31 are distributed along the height direction of the fixed ring 1, while the extension direction of the sliding groove 32 is perpendicular to the height direction and perpendicular to the second rotation axis, and the guide post 22 and the fourth connecting part 31 are distributed along the extension direction of the guide groove. This design ensures that the rotating component 3 closely follows the relative rotation between the fixed ring 1 and the rotating ring 2, thereby enabling the pointer 33 to accurately indicate the real-time relative angle between the rotating ring 2 and the fixed ring 1, while also preventing the rotating component 3 from restricting the rotation of the rotating ring 2 relative to the fixed ring 1.

[0051] Furthermore, when the rotating ring 2 is in the first position, the center of the guide post 22 of the rotating ring 2 and the center of the fourth connecting part 31 of the rotating member 3 have a first distance L1 in the height direction of the fixed ring 1; when the rotating ring 2 is in the second position, the center of the guide post 22 and the center of the fourth connecting part 31 have a second distance L2 in the extension direction of the sliding groove 32 of the rotating member 3, and the second distance L2 is preferably between 2.5 times and 4.75 times the first distance L1. This design is beneficial for miniaturizing the rotating member 3 as much as possible, thereby optimizing the structure of the rotation adjustment mechanism 101 and making the overall design of the rotation adjustment mechanism 101 more reasonable and compact.

[0052] Furthermore, the display slot 13 is preferably arc-shaped, and the first central angle α1 of the display slot 13 is preferably between 30° and 120°. The angle scale 14 is distributed according to the second central angle; wherein the second central angle is equal to the first central angle α1, and the maximum scale value of the angle scale 14 is between 10° and 60°. Through the structural design of the display slot 13 and the distribution design of the angle scale 14, the rotation adjustment mechanism 101 can at least meet the angle adjustment needs of most existing lamps 100, and enable installers or users to quickly, clearly, and accurately read the angle scale 14 indicated by the pointer 33; in addition, the structural design of the display slot 13 can also improve the aesthetics of the rotation adjustment mechanism 101.

[0053] Preferably, the actual scale value of each graduation of the angle scale 14 is 2 to 3 times the angle value of the second central angle occupied by that graduation; that is, the actual angle value of the actual graduation corresponds to 2 to 3 times its own value in the second central angle. Here, the actual scale value refers to the actual rotation of the rotating ring 2 relative to the fixed ring 1 corresponding to the angle scale 14. For example, if the rotating ring 2 rotates 2° relative to the fixed ring 1, the actual scale value is 2°. The aforementioned angle value of the occupied second central angle refers to the angle value of the second central angle occupied between two adjacent graduations. For example, when the actual scale value is 2°, the graduation is actually between 4° and 6° of the second central angle. This design optimizes the magnified display function of the angle scale 14, enabling installers or users to read the angle scale 14 pointed to by the pointer 33 more quickly, clearly, and accurately.

[0054] Taking this embodiment as an example, in this embodiment: the second distance L2 is preferably 3.25 times the first distance L1; the first central angle is preferably 90°; the actual scale value of each scale of the angle scale 14 is 2.5 times the angle value of the second central angle occupied by that scale (that is, the maximum scale value of the angle scale 14 corresponds to 45°). This design can optimize or optimize the overall structure of the rotation adjustment mechanism 101, thereby making the overall structure of the rotation adjustment mechanism 101 more optimized and compact. For example, when the rotating ring 2 is in the first position, the value of the first distance L1 is assumed to be 2 mm. Then, when the rotating ring 2 is in the second position, the value of the second distance L2 is 6.5 mm. Furthermore, when the rotating ring 2 is in the second position, a second connecting part 21 of the rotating ring 2 and the fourth connecting part 31 of the rotating member 3 form a second connecting line, a third connecting part 31 and the guide post 22 of the rotating ring 2 form a third connecting line, and a fourth connecting part 21 and the guide post 22 form a fourth connecting line. The second included angle α2 between the second and third connecting lines is preferably 90°, and the third included angle α3 between the second and fourth connecting lines is preferably 33°. As another example, when the rotating ring 2 is in the third position relative to the fixed ring 1... Figure 10 As shown, when the rotating ring 2 rotates at an angle a4 (assumed to be 15°) relative to the fixed ring 1, the distance between the center of the fourth connecting part 31 and the center of the guide post 22 is the third distance L3 (approximately 3.5 mm corresponding to a4).

[0055] It should be noted that in other embodiments, the first central angle a1 of the display slot 13 may also be 30°, 60° or 120°, etc.; the second distance L2 may also be 2 times, 3 times or 4.75 times the first distance L1, etc.; the actual scale value of each scale of the angle scale 14 is 2 times or 3 times the angle value of the second central angle occupied by that scale, etc.; therefore, they will not be described one by one here.

[0056] Furthermore, when the rotating ring 2 is in the second position, the center of the pointer 33 is preferably offset from the guide post 22 relative to the line connecting the center of the second connecting part 21 and the center of the fourth connecting part 31; of course, as another optional solution, when the rotating ring 2 is in the second position, the center of the pointer 33 can also be located on the connecting line. In addition, the center of the second rotation axis is preferably located at half the width of the slide groove 32. By designing the position of the pointer 33, it can better point to the angle scale 14; and by designing the position of the second rotation axis, the rotating member 3 can rotate better relative to the fixed ring 1, and the guide post 22 can slide more smoothly along the slide groove 32.

[0057] In summary, the design of the rotation adjustment mechanism 101 of the lamp 100 makes it simpler and more convenient to adjust the illumination angle of the lamp 100, and enables installers or users to read the angle scale 14 pointed to by the pointer 33 more quickly, clearly and accurately.

[0058] Lighting System Examples

[0059] The lighting system includes a control terminal and the luminaires described in the above-described luminaire embodiments. The luminaires also include a power control unit, which is electrically connected to the light source to control the light source to provide illumination according to a set mode.

[0060] The control terminal is used to establish an electrical connection with the power control unit of the lighting fixture, and / or to interact with the power control unit of the lighting fixture. The control terminal can be a conventional control panel (such as a mechanical switch panel), a smart control panel, or a remote control. When the control terminal is a conventional control panel, it is electrically connected to the power control unit. When the control terminal is a smart control panel or a remote control, the power control unit 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 power control unit, and / or the first wireless communication module interacts with the second wireless communication module. Furthermore, the control terminal can also be a smart mobile terminal (such as a mobile phone, tablet computer, smart wearable device, etc.), or even an artificial intelligence robot. By setting up the aforementioned lighting fixtures, the lighting system makes adjusting the illumination angle of the fixtures simpler and more convenient, and allows installers or users to read the angle scale indicated by the pointer on the fixture more quickly, clearly, and accurately.
