Description

Technical Field

[0001] The present invention relates to the field of lighting technology, in particular to a rotation adjustment mechanism, a lamp provided with the rotation adjustment mechanism, and a lighting system provided with the lamp. Background Art

[0002] With the rise and popularity of designs without main lights, lamps such as downlights, spotlights, track lights, and line lights are favored by consumers. Taking spotlights as an example, such lamps usually include a fixed ring, a rotating ring, a lamp body, a light source, an optical element, etc.; the fixed ring is used to be fixedly connected to the ceiling so that the lamp can be installed on the ceiling, the fixed ring has a receiving position, the rotating ring is located in the receiving position and is rotatably connected to the fixed ring, the lamp body is installed on the rotating ring so as to rotate with the rotating ring relative to the fixed ring, the light source is installed in the lamp body, the optical element is installed on the rotating ring and / or the lamp body, and the light source is set toward the optical element; when installing and using the lamp, the relative position of the rotating ring and the fixed ring is often adjusted according to specific lighting requirements so that the lighting angle reaches the effect required by the user. Such as Figure 1 As shown, the existing fixed ring 9 is usually provided with an angle scale 91 and a display slot 92, and the rotating ring is provided with a corresponding pointer at the display slot 92, so that the installer or user can determine the adjusted lighting 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 at non-0°, the first axis and the second axis form a non-zero angle), and the rotation adjustment angle range is not large; and because the angle scale 91 on the fixed ring 9 is configured 1:1 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 ), which results in a limited display area of ​​the angle scale 91, making it difficult for installers or users to quickly, clearly and accurately read the angle scale 91 indicated by the pointer, increasing the difficulty of installation and adjustment for installers or users and reducing the experience of installers or users. 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 mechanism with easier identifiable angle scales.

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

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

[0007] In order to achieve the main purpose of the present invention, the present invention provides a rotation adjustment mechanism, including a fixed ring and a rotating ring, the fixed ring has a accommodating position, a first connecting part, a display slot and an angle scale, the rotating ring is arranged in the accommodating position, the rotating ring has a second connecting part, the second connecting part is rotatably connected to the first connecting part around the first rotation axis, wherein the fixed ring also has a third connecting part, the angle scale is distributed around the third connecting part, the display slot is located between the third connecting part and the angle scale, the rotating ring has a guide column, the guide column extends toward the display slot parallel to the first rotation axis, the rotation adjustment mechanism also includes a rotating member, the rotating member has a fourth connecting part, a slide slot and a pointer, the fourth connecting part is rotatably connected to the third connecting part around the second rotation axis, the second rotation axis is parallel to the first rotation axis, the guide column is slidably arranged in the slide slot, and the pointer is located at the display slot.

[0008] It can be seen from the above that, through the structural design of the rotating part, and the matching structural design of the fixed ring, the rotating ring and the rotating part, the angle scale on the fixed ring can enlarge the angle scale distribution area according to the set ratio, which is beneficial to increase the angle scale display area, so that the angle scale has an enlarged display function, which makes it easier for installers or users to identify the angle scale value indicated by the pointer, making the design of the rotation adjustment mechanism more humane, reducing the difficulty of adjusting the lighting angle and installing the lamp equipped with the rotation adjustment mechanism for installers or users, and improving the experience of installers or users.

[0009] A further solution 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 column are distributed in sequence along the height direction of the fixed ring, and the slide 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 slide groove is perpendicular to the height direction, and the guide column and the fourth connecting part are distributed along the extension direction.

[0010] As can be seen from the above, this design can ensure that the rotating member closely follows the relative rotation between the fixed ring and the rotating ring, so that the pointer can accurately point out the real-time relative angle between the rotating ring and the fixed ring, while also preventing the rotating member from restricting the rotation of the rotating ring relative to the fixed ring.

[0011] A further solution is that when the rotating ring is in the first position, the center of the guide column 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 column 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 part as much as possible, so as to optimize the structure of the rotation adjustment mechanism, and make the overall design of the rotation adjustment mechanism more reasonable and compact.

[0013] A further solution is that the display slot is arc-shaped, and the first central angle of the display slot is between 30° and 120°; the angle scale is distributed according to the second central angle, the second central angle 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 at least meet the angle adjustment requirements of most existing lamps, and enables 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 enhance the aesthetics of the rotation adjustment mechanism.

[0015] A further solution is that the actual scale value of each scale of the angle scale is 2 to 3 times the angle value of the second central angle occupied by the scale.

[0016] As can be seen from the above, the design can optimize the magnified display function of the angle scale, so that the installer or user can read the angle scale indicated by the pointer more quickly, clearly and accurately.

[0017] A further solution is that the second distance is 3.25 times the first distance; the first center angle is 90°; and the actual scale value is 2.5 times the angle value.

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

[0019] A further solution is that the first connecting part is a countersunk hole, the second connecting part is provided with a first connecting hole matching the countersunk hole, the rotation adjustment mechanism also includes a first fastener, the first fastener has a first shaft section and a first connecting section, the first shaft section is rotatably connected to the countersunk hole, and the first connecting section is connected to the first connecting hole; the third connecting part is a first through hole, the fourth connecting part is a first connecting column, the first connecting column is inserted into the first through hole and is rotatably connected to the first through hole, or the third connecting part is a second connecting column, the fourth connecting part is a second through hole, the second connecting column is inserted into the second through hole and is 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, the rotation adjustment mechanism also includes a second fastener, the second fastener has a second shaft section and a second connecting section, the second shaft section is rotatably connected to the third through hole, and the second connecting section is connected to the second connecting hole.

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

[0021] A further solution is that when the rotating ring is in the second position, the center of the pointer is offset away from the guide column 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 rotation axis is located at half the width of the slide groove.

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

[0023] In order to achieve another object of the present invention, the present invention provides a lamp, including a lamp body, characterized in that the lamp also includes the above-mentioned rotation adjustment mechanism, and the lamp body is installed on a rotating ring.

Specifically, the angle scale 14 includes a plurality of scale lines 141, and the plurality of scale lines 141 are distributed around the third connecting part 15 with the third connecting part 15 as the center of the circle.

[0043] Combination Figure 4 The rotating ring 2 is arranged in the receiving position 11 of the fixed ring 1, and the rotating ring 2 has a second connecting portion 21. The number of the second connecting portions 21 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 column 22 on one side close to the display through slot 13 of the fixed ring 1, and the guide column 22 is parallel to the first axis and extends toward the display through slot 13.

[0044] Preferably, as in the present embodiment, the first connection part 12 is a countersunk hole, and the second connection part 21 is provided with a first connection hole 211 matching the countersunk hole; in addition, the rotation adjustment mechanism 101 also includes a first fastener, the number of which is equal to the number of the first connection parts 12, so that one first fastener is matched and connected with a corresponding first connection part 12 and a second connection part 21; the first fastener preferably has a first shaft section and a first connection section, and when the first fastener is matched and connected with the first connection part 12 and the second connection part 21, the first shaft section is rotatably connected with the countersunk hole, and the first connection section is connected with the first connection hole 211 (such as threaded connection, interference fit, adhesive fixation, etc.). Among them, the first shaft section 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 member 3 is located in the receiving position 11 of the fixed ring 1, and the rotating member 3 is linked between the fixed ring 1 and the rotating ring 2. The rotating ring 2 is located between the display slot 13 and the guide column 22; the rotating member 3 has a fourth connecting portion 31, a sliding slot 32 and a pointer 33.

[0046] The fourth connecting portion 31 is rotatably connected to the third connecting portion 15 of the fixing ring 1 around the second rotation axis, wherein the second rotation axis is parallel to the first rotation axis. Preferably, as in the present embodiment, the third connecting portion 15 is a first through hole, the fourth connecting portion 31 is a first connecting column, and the first connecting column protrudes from the rotating member 3 toward the first through hole in parallel with the second rotation axis, so that when the rotating member 3 is assembled with the fixing member, the first connecting column is inserted into the first through hole, and the first connecting column and the first through hole are rotatably connected; this design facilitates the assembly of the rotating member 3 with the fixing ring 1. Of course, as another optional solution, in another embodiment, the third connecting portion 15 can also be a second connecting column, and the second connecting column protrudes from the fixing member toward the rotating member 3 in parallel with the rotation axis, and the fourth connecting portion 31 is a second through hole, so that when the rotating member 3 is assembled with the fixing member, the second connecting column is inserted into the second through hole, and the second connecting column and the second through hole are rotatably connected. Alternatively, as another optional scheme, in another embodiment, the third connecting part 15 can be set as a third through hole or a second countersunk hole, and matchingly, a second connecting hole is set on the fourth connecting part 31; the rotation adjustment mechanism 101 also includes a second fastener, and the second fastener preferably has a second axial section and a second connecting section; when the second fastener, the third connecting part 15 and the fourth connecting part 31 are connected, the second axial end of the second fastener is placed in the third through hole and rotatably connected to the third through hole, and the second connecting section 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 portion 31 are distributed on two sides opposite to the rotating member 3 on the second rotation axis. When the rotating member 3 is assembled with the rotating ring 2, the rotating guide column 22 is placed in the slide groove 32 of the rotating member 3 so that the guide column 22 can slide in the slide groove 32. The pointer 33 and the slide groove 32 are distributed on two sides opposite to 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 pointed by the pointer 33.

[0048] Through the above-mentioned structural design of the rotating part 3, and the matching structural design of the fixed ring 1, the rotating ring 2 and the rotating part 3, the angle scale 14 on the fixed ring 1 can enlarge the distribution area of ​​the angle scale 14 according to the set ratio, which is beneficial to increase the display area of ​​the angle scale 14, so that the angle scale 14 has an enlarged display function, which makes it easier for installers or users to identify the angle scale 14 value indicated by the pointer 33, making the design of the rotating adjustment mechanism 101 more humane, reducing the difficulty of adjusting the lighting angle and installing the lamp 100 provided with the rotating adjustment mechanism 101 for installers or users, and improving the experience of installers or users.

[0049] The following is further combined Figures 8 to 12 Provide explanation;

[0050] The rotating ring 2 has at least a first position relative to the fixed ring 1 (eg Figure 7 , Fig. 9 as shown) and a second position (as Figure 8 , Fig.11 As shown). When the rotating ring 2 is in the first position, the second connection part 21 of the rotating ring 2, the third connection part 15 of the rotating member 3 and the guide column 22 of the rotating ring 2 are sequentially distributed along the height direction of the fixed ring 1, and the slide groove 32 of the rotating member 3 is parallel to the height direction; when the rotating ring 2 is in the second position, the second connection part 21 and the fourth connection part 31 are distributed along the height direction of the fixed ring 1, and the extension direction of the slide groove 32 is perpendicular to the height direction and perpendicular to the second rotation axis, and the guide column 22 and the fourth connection part 31 are distributed along the extension direction of the guide groove. This design can ensure that the rotating member 3 rotates closely following the relative rotation between the fixed ring 1 and the rotating ring 2, so that the pointer 33 can accurately point out the real-time relative angle between the rotating ring 2 and the fixed ring 1, and at the same time can prevent the rotating member 3 from limiting the rotation of the rotating ring 2 relative to the fixed ring 1.

[0051] In addition, when the rotating ring 2 is in the first position, the center of the guide column 22 of the rotating ring 2 and the center of the fourth connection 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 column 22 and the center of the fourth connection part 31 have a second distance L2 in the extension direction of the slide slot 32 of the rotating member 3, and the second distance L2 is preferably between 2.5 and 4.75 times the first distance L1. This design is conducive to miniaturizing the rotating member 3 as much as possible, so as to optimize the structure of the rotation adjustment mechanism 101, and make 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 center angle a1 of the display slot 13 is preferably between 30° and 120°. The angle scale 14 is distributed according to the second center angle; wherein the second center angle is equal to the first center angle a1, 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 requirements of most existing lamps 100, and enable the installer or user 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 scale of the angle scale 14 is 2 to 3 times the angle value of the second center angle occupied by the scale; that is, the actual scale value corresponds to the actual angle value in the second center angle 2 to 3 times itself. The actual scale value refers to: the value of the angle scale 14 actually corresponding to the rotation of the rotating ring 2 relative to the fixed ring 1, such as the rotating ring 2 actually rotates 2° relative to the fixed ring 1, then the actual scale value is 2°; and the angle value of the second center angle occupied by the aforementioned refers to: the value of the angle of the second center angle occupied between two adjacent scales, such as when the actual scale value is 2°, the scale is actually between 4° and 6° of the second center angle. This design can optimize the magnified display function of the angle scale 14, so that the installer or user can read the angle scale 14 indicated by the pointer 33 more quickly, more clearly, and more 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 center 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 center angle occupied by the scale (that is, the maximum scale value of the angle scale 14 corresponds to 45°). This design can make the overall structure of the rotation adjustment mechanism 101 more optimized or optimized, 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; in addition, when the rotating ring 2 is in the second position, a second connecting line is formed between the second connecting portion 21 of the rotating ring 2 and the fourth connecting portion 31 of the rotating member 3, a third connecting line is formed between the fourth connecting portion 31 and the guide column 22 of the rotating ring 2, and a fourth connecting line is formed between the second connecting portion 21 and the guide column 22. The second angle a2 between the second connecting line and the third connecting line is preferably 90°, and the third angle a3 between the second connecting line and the fourth connecting line is preferably 33°. For another example, when the rotating ring 2 is relative to the fixed ring 1 to the third position [as Fig.10 As shown, when the rotation angle of the rotating ring 2 relative to the fixed ring 1 is a4 (assuming it is 15°), the distance between the center of the fourth connecting portion 31 and the center of the guide column 22 is the third distance L3 (corresponding to a4 is approximately 3.5 mm).

[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, etc. of the first distance L1; the actual scale value of each scale of the angle scale 14 is 2 times or 3 times, etc. the angle value of the second central angle occupied by the scale; therefore, examples are not given 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 portion 21 and the center of the fourth connecting portion 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 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 better rotate 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 easier and more convenient to adjust the lighting angle of the lamp 100, and enables the installer or user to read the angle scale 14 indicated by the pointer 33 more quickly, clearly and accurately.

[0060] The control terminal is used to establish an electrical connection with the power control unit of the lamp, and / or the control terminal is used to exchange information with the power control unit of the lamp. Wherein, 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 power control unit. When the control terminal is an intelligent control panel or a remote control, a first wireless communication module is provided on the power control unit, and a second wireless communication module is provided on the control terminal; the control terminal is electrically connected to the power control unit, and / or the first wireless communication module exchanges information with the second wireless communication module. In addition, the control terminal can also be an intelligent mobile terminal (such as a mobile phone, a tablet computer, an intelligent wearing device, etc.), and can also be an artificial intelligence robot. By setting the above-mentioned lamp, the lighting system makes it easier and more convenient to adjust the illumination angle of the lamp, and enables the installer or user to read the angle scale indicated by the pointer on the lamp more quickly, more clearly and more accurately.
