[0027] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0028] See also Figure 1, an embodiment of the present application provides a lamp device 100, and the lamp device 100 is used to illuminate the application environment where the lamp device 100 is located. In this embodiment, the lamp device 100 may include a lighting component, which serves as a light source of the lamp device 100 and emits lighting light. As an example, the lighting component may include a plurality of lighting lamps, and the plurality of lighting lamps are connected and arranged in a chain shape, and two adjacent lighting lamps are rotatably connected. The lamp device 100 in this embodiment also includes a wire, which is used to connect the two lighting lamps to establish an electrical connection relationship between the two lighting lamps. For the convenience of distinction, one of the two adjacent lighting lamps is defined as a first lighting lamp 10, and the other is defined as a second lighting lamp 20. The lighting lamps in this embodiment (including the first lighting lamp 10 and the second lighting lamp 20) have a length dimension, a width dimension and a thickness dimension, wherein the length dimension>width dimension>thickness dimension.

[0029] In this embodiment, the first illuminating lamp 10 and the second illuminating lamp 20 can be arranged in parallel and spaced apart along a first direction and can be rotatably connected, wherein the first direction can be a direction corresponding to the length dimension of the illuminating lamp. In this embodiment, the direction in which the length dimension of the illuminating lamp is located, i.e., the first direction, can be arranged in a horizontal direction, so that the first illuminating lamp 10 and the second illuminating lamp 20 are arranged in a horizontal direction and can be rotatably connected. Based on the horizontally arranged first direction, this embodiment arranges the first illuminating lamp 10 to rotate relative to the second illuminating lamp 20 around a vertically arranged axis. In the initial state, the direction of the light-emitting side of the first illuminating lamp 10 and the direction of the light-emitting side of the second illuminating lamp 20 can be roughly consistent. In actual application scenarios, the light-emitting sides of the two illuminating lamps can be adjusted to be close to each other to increase the intensity of the illumination light emitted by the lamp device 100, and the light-emitting sides of the two illuminating lamps can be adjusted to be away from each other to increase the illumination range of the lamp device 100 in the horizontal direction.

[0030] In some other embodiments, the first illuminating lamp 10 may be stacked on the second illuminating lamp 20 along the second direction and rotatably connected to the second illuminating lamp 20, wherein the second direction may be the direction corresponding to the width dimension of the illuminating lamp. In this embodiment, the direction of the width dimension of the illuminating lamp, i.e., the second direction, may be arranged in the vertical direction so that the first illuminating lamp 10 is stacked on the second illuminating lamp 20 along the vertical direction. Based on the second direction arranged vertically, this embodiment arranges the first illuminating lamp 10 to rotate relative to the second illuminating lamp 20 around the horizontally arranged axis. In the initial state, the direction of the light-emitting side of the first illuminating lamp 10 and the direction of the light-emitting side of the second illuminating lamp 20 may be roughly consistent. In actual application scenarios, the light-emitting sides of the two illuminating lamps may be adjusted to be close to each other to increase the illumination light intensity emitted by the lamp device 100, or the light-emitting sides of the two illuminating lamps may be adjusted to be away from each other to increase the illumination range of the lamp device 100 in the vertical direction. In some other embodiments, the first illuminating lamp 10 and the second illuminating lamp 20 may be arranged side by side in other directions.

[0031] See also Figure 1 and Figure 2 In this embodiment, the lamp device 100 may further include a connecting member 30 and a rotating shaft positioning member 40. The connecting member 30 is connected between the first illuminating lamp 10 and the second illuminating lamp 20. The connecting member 30 is superimposed on the first illuminating lamp 10 along the direction of the first axis L and is rotatably connected to the first illuminating lamp 10. The first illuminating lamp 10 can rotate around the first axis L relative to the second illuminating lamp 20. In this embodiment, the first axis L extends substantially in the direction of the width dimension of the illuminating lamp. The rotating shaft positioning member 40 is fixedly connected to the first illuminating lamp 10, and the rotating shaft positioning member 40 cooperates with the connecting member 30 to limit the rotation of the first illuminating lamp 10 relative to the connecting member 30, and is also used to adjust the position of the first illuminating lamp 10 relative to the connecting member 30.

[0032] Specifically, see Figure 3 and Figure 4The shaft positioning member 40 in this embodiment includes an elastic matching portion 411. Correspondingly, the first anti-slip portion 311 is provided on the side of the connecting member 30 facing the shaft positioning member 40. The first anti-slip portion 311 and the elastic matching portion 411 are correspondingly arranged and engaged with each other to limit the first lighting lamp 10 from rotating around the first axis L relative to the connecting member 30. The elastic matching portion 411 in this embodiment is a structure with elastic deformation capability. In actual application scenarios, when a user pushes the first lighting lamp 10, the first lighting lamp 10 can transmit external force to the elastic matching portion 411. The elastic matching portion 411 and the first anti-slip portion 311 are pressed against each other. The elastic matching portion 411 with deformation capability can be deformed to move relative to the first anti-slip portion 311. As can be seen from the foregoing, the shaft positioning member 40 is fixedly connected to the first lighting lamp 10, and the first lighting lamp 10 can rotate around the first axis L relative to the connecting member 30. Therefore, the elastic fitting portion 411 can be deformed and rotate around the first axis L relative to the first anti-slip portion 311, thereby enabling the first lighting lamp 10 to rotate around the first axis L relative to the connecting member 30 and the second lighting lamp 20 to adjust the positional relationship between the first lighting lamp 10 and the second lighting lamp 20.

[0033] In summary, the first illuminating lamp 10 in the illuminating device 100 provided in the present embodiment is provided with a rotating shaft positioning member 40, and the elastic matching portion 411 of the rotating shaft positioning member 40 can be engaged with the first anti-slip portion 311 of the connecting member 30, so as to limit the rotation of the first illuminating lamp 10 relative to the connecting member 30 and the second illuminating lamp 20, and improve the structural stability of the illuminating device. The elastic matching portion 411 with deformation ability can directly rotate around the first axis L relative to the connecting member 30 under the action of external force, so that the first illuminating lamp 10 rotates around the first axis L relative to the second illuminating lamp 20. Therefore, under the setting of the present embodiment, it is not necessary to disassemble the illuminating device 100 in order to release the locking limit relationship between the elastic matching portion 411 and the first anti-slip portion 311, and the first illuminating lamp 10 can be directly pushed to adjust the position relationship of the first illuminating lamp 10 relative to the second illuminating lamp 20, which is simple to operate. In addition, the engagement of the first anti-slip portion and the elastic matching portion can limit the size of the rotation angle of the first illuminating lamp, and avoid excessive rotation angle.

[0034] In this embodiment, the connecting member 30 is also rotatably connected to the second illuminating lamp 20 , which will be described in detail later. In other embodiments, the connecting member 30 may be rotatably connected to only one of the first illuminating lamp 10 and the second illuminating lamp 20 .

[0035] Next, the structures of the connecting member 30 , the rotating shaft positioning member 40 and the first lighting lamp 10 and the matching relationship among the three are introduced.

[0036] See also Figure 3 and Figure 5In this embodiment, the first lighting lamp 10 includes a first housing 11 and a first rotating shaft 12. The first rotating shaft 12 is connected to the first housing 11 and protrudes relative to the first housing 11. The axis of the first rotating shaft 12 is the first axis L mentioned above. In this embodiment, the rotating shaft positioning member 40 itself is a plastic sleeve with elastic deformation ability, which is sleeved on the outer periphery of the first rotating shaft 12. Correspondingly, the connecting member 30 in this embodiment is a structure with low elastic deformation ability, such as a metal block made of rigid material (aluminum and its alloys, copper and its alloys, etc.), or a hard plastic block made of flexible material (resin, polyethylene, etc.). The connecting member 30 is rotatably matched with the first rotating shaft 12, and the first anti-slip portion 311 on the connecting member 30 is matched with the elastic matching portion 411 on the rotating shaft positioning member 40. The lamp device 100 in this embodiment may further include a fixing member 50, which is sequentially inserted into the connecting member 30 and the rotating shaft positioning member 40 and locked to the first rotating shaft 12 to connect the first housing 11 and the connecting member 30, and ensure that the first anti-slip portion 311 and the elastic matching portion 411 are tightly buckled to have a good limiting effect. In some embodiments, the rotating shaft positioning member 40 and the elastic matching portion 411 may be structures with low elastic deformation ability, and the connecting member 30 and the first anti-slip portion 311 may be structures with elastic deformation ability. In some other embodiments, the rotating shaft positioning member 40 and the connecting member 30 may both be structures with a certain elastic deformation ability.

[0037] See also Figure 3 and Figure 4 In this embodiment, the first anti-slip portion 311 includes a plurality of first anti-slip teeth 3111, which are protruding from a side surface of the connecting member 30 facing the rotating shaft positioning member 40, and the plurality of first anti-slip teeth 3111 are arranged around the first axis L. Correspondingly, the elastic matching portion 411 includes a plurality of matching teeth 4111, which are protruding from an end surface of the rotating shaft positioning member 40 facing the connecting member 30, and the plurality of matching teeth 4111 are arranged around the first axis L. The plurality of matching teeth 4111 and the plurality of first anti-slip teeth 3111 are meshed and matched to limit the rotation of the rotating shaft positioning member 40 and the first lighting lamp 10 relative to the connecting member 30. In this embodiment, the plurality of first anti-slip teeth 3111 radiate outwards with a point on the first axis L as the center of the circle to form a radial shape, and correspondingly, the plurality of matching teeth 4111 radiate outwards with a point on the first axis L as the center of the circle to form a radial shape. In other embodiments, the first anti-slip portion 311 and the elastic matching portion 411 may be end face gear plates meshing with each other.

[0038] See also Figure 5 and Figure 6In this embodiment, the shaft positioning member 40 further includes a connecting portion 412, which is integrally formed with the elastic matching portion 411 mentioned above. In this embodiment, the connecting portion 412 is the main structure of the shaft positioning member 40, and the connecting portion 412 is a sleeve-shaped structure, and the connecting portion 412 is sleeved on the outer periphery of the first shaft 12. The connecting portion 412 is connected to the first shell 11 in a matching manner. Specifically, the connecting portion 412 is recessed toward one side of the first shell 11 and defines a first positioning portion 4121, and the first positioning portion 4121 is a groove structure. Correspondingly, a second positioning portion 13 is convexly provided on the first shell 11, and the second positioning portion 13 is a convex block structure. When the connecting portion 412 is connected to the first shell 11, the second positioning portion 13 is embedded in the first positioning portion 4121. The arrangement of this embodiment has met the requirement of fixed connection between the rotating shaft positioning member 40 and the first lighting lamp 10. The cooperation between the second positioning portion 13 and the first positioning portion 4121 can limit the rotation of the rotating shaft positioning member 40 relative to the first housing 11, and ensure the stability of the meshing relationship between the rotating shaft positioning member 40 and the connecting member 30. In some embodiments, an adhesive can be applied between the connecting portion 412 and the first housing 11 to further fix the rotating shaft positioning member 40 and the first housing 11. In this embodiment, there are multiple first positioning portions 4121. As can be seen from the foregoing, multiple first positioning portions 4121 can be arranged around one end of the rotating shaft positioning member 40 facing the first housing 11. Correspondingly, there are multiple second positioning portions 13, and multiple second positioning portions 13 and multiple first positioning portions 4121 are arranged one by one. In other embodiments, the rotating shaft positioning member 40 and the first housing 11 can also be fixedly connected by bonding, welding, hot melting, etc.

[0039] See also Figure 6 In this embodiment, the shaft positioning member 40 further includes a limiting flange 413, which is circumferentially arranged on the outer periphery of the connecting portion 412. The limiting flange 413 has a certain size in the radial direction of the sleeve-shaped connecting portion 412, that is, the limiting flange 413 protrudes in the radial direction of the connecting member 30 relative to the outer peripheral surface of the connecting portion 412. In this embodiment, the shaft positioning member 40 is a plastic sleeve with elastic deformation ability, so the limiting flange 413 as a part of the structure of the shaft positioning member 40 also has elastic deformation ability. When the connecting member 30, the shaft positioning member 40 and the first shell 11 are in an assembled state, the limiting flange 413 is clamped between the first shell 11 and the connecting member 30, which can avoid friction between the connecting member 30 and the first shell 11. The limiting flange 413 is an elastic structure, which has less wear on the structures of the connecting member 30 and the first shell 11.

[0040] See also Figure 2 and Figure 5In this embodiment, the first housing 11 is roughly a rectangular parallelepiped structure, and a first accommodating groove 111 is provided on one side of the first housing 11 in the second direction (the direction where the width dimension of the illuminating lamp is located), and the first accommodating groove 111 is located at a corner of the rectangular parallelepiped structure, that is, the first accommodating groove 111 is connected to three outer surfaces of the rectangular parallelepiped structure that intersect with each other. The first rotating shaft 12 and the second positioning portion 13 mentioned above are both arranged at the bottom side of the first accommodating groove 111, and the rotating shaft positioning member 40 is sleeved on the first rotating shaft 12 and accommodated in the first accommodating groove 111. The connecting member 30 has a first end 31 and a second end 32 in its extension direction, wherein the first anti-slip portion 311 is arranged on the side of the first end 31 facing the first housing 11. When the connecting member 30, the rotating shaft positioning member 40 and the first housing 11 are in an assembled state, the first end 31 of the connecting member 30 is overlapped on the bottom side of the first accommodating groove 111 along the first axis L direction and is at least partially embedded in the first accommodating groove 111. In actual application scenarios, the edge structure of the first accommodating groove 111 can abut against the structure of the connecting piece 30 to limit the first shell 11 from continuing to rotate, thereby preventing excessive rotation from causing the wires between the first lighting lamp 10 and the second lighting lamp 20 to be pulled, and preventing the wires from breaking or losing electrical connection with the electrical components in the first lighting lamp 10 and the second lighting lamp 20.

[0041] Next, the structures of the second end 32 of the connecting member 30 and the second lighting lamp 20 and the matching relationship therebetween are described.

[0042] See also Figure 2 In this embodiment, the second end 32 of the connecting member 30 is overlapped with the second lighting lamp 20 along the second axis M, and the second lighting lamp 20 can rotate around the second axis M relative to the connecting member 30. In this embodiment, the extension direction of the second axis M is substantially the direction of the width of the lighting lamp. Figure 4 and Figure 7 In this embodiment, the second lighting lamp 20 includes a second housing 21 and a second rotating shaft 22. The second rotating shaft 22 is connected to the second housing 21 and protrudes relative to the second housing 21. The axis of the second rotating shaft 22 is the second axis M mentioned above. The second end 32 of the connecting member 30 is rotatably connected with the second rotating shaft 22. A second anti-slip portion 321 is provided on the side of the second end 32 of the connecting member 30 facing the second housing 21. Correspondingly, a clamping portion 23 is provided on the side of the second housing 21 facing the second end 32. The clamping portion 23 is clamped with the second anti-slip portion 321 to limit the rotation of the connecting member 30 relative to the second housing 21. The connecting member 30 and the second housing 21 can also be connected by a fixing member 50. The fixing member 50 is passed through the second end 32 and locked to the second rotating shaft 22 to connect the second housing 21 and the second end 32 of the connecting member 30, and ensure that the second anti-slip portion 321 and the clamping portion 23 are tightly clamped to have a good limiting effect.

[0043] See also Figure 4 and Figure 7 In this embodiment, the second anti-slip portion 321 includes a plurality of second anti-slip teeth 3211, which are protruding from a side surface of the second end 32 of the connecting member 30 facing the second housing 21, and are arranged around the second axis M. Correspondingly, the engaging portion 23 includes a plurality of third anti-slip teeth 231, which are protruding from an end surface of the second housing 21 facing the connecting member 30, and are arranged around the second axis M. The plurality of second anti-slip teeth 3211 and the plurality of third anti-slip teeth 231 are meshed with each other to limit the second lighting lamp 20 from rotating relative to the second end 32 of the connecting member 30. In other embodiments, the second anti-slip portion 321 and the engaging portion 23 may be end face gear plates meshing with each other. In some embodiments, the second end 32 of the connecting member 30 and the second shell 21 may also be provided with the shaft positioning member 40 mentioned above. In this type of embodiment, the structure of the second end 32 and the structure of the second shell 21 can refer to the structure of the first end 31 and the first shell 11 mentioned above, and will not be repeated here.

[0044] See also Figure 7 In this embodiment, the second shell 21 is roughly a rectangular parallelepiped structure. The second shell 21 is provided with a second accommodating groove 211 on one side in the second direction (the direction where the width dimension of the lighting lamp is located). The second accommodating groove 211 is located at a corner of the rectangular parallelepiped structure, that is, the second accommodating groove 211 is connected to three outer surfaces of the rectangular parallelepiped structure that intersect with each other. The above-mentioned engaging portion 23 and the second rotating shaft 22 are both arranged on the bottom side of the second accommodating groove 211. The second anti-slip portion 321 is arranged on the side of the second end 32 facing the second shell 21. When the second end 32 of the connecting member 30 and the second shell 21 are in an assembled state, the second end 32 of the connecting member 30 is overlapped on the bottom side of the second accommodating groove 211 along the second axis M direction and is at least partially embedded in the second accommodating groove 211. In actual application scenarios, when the locking portion 23 and the second anti-slip portion 321 of the connecting member 30 are separated and the locking relationship is released, the connecting member 30 can rotate around the second rotation axis 22, and the edge structure of the second accommodating groove 211 can abut against the structure of the second end 32 of the connecting member 30 to limit the connecting member 30 from continuing to rotate around the second rotation axis 22 relative to the second shell 21.

[0045] See also Figure 8In this embodiment, a wire entry hole 212 is provided on the second housing 21, and the wire entry hole 212 can connect the interior and exterior of the second housing 21. The wire used to electrically connect the two illuminating lamps can be inserted into the interior of the second housing 21 through the wire entry hole 212 and electrically connected to the electrical components in the second housing 21. In this embodiment, a plurality of wire entry holes 212 can be provided, so that the second illuminating lamp 20 can establish an electrical connection relationship with a plurality of illuminating lamps, and the wire of the second illuminating lamp 20 can also extend to the outside through the wire entry hole 212 to be electrically connected to an external power supply or control module.

[0046] See also Figure 8 In this embodiment, the second lighting lamp 20 may further include a glue potting holding portion 24, which is connected to the second shell 21. The local structure of the glue potting holding portion 24 is spaced apart from the second shell 21 and defines a receiving chamber 241. The wire entry through hole 212 mentioned above can communicate the receiving chamber 241 with the interior of the second shell 21. It should be understood that the wire entry through hole 212 is located on the inner wall of the receiving chamber 241. The wire of the first lighting lamp 10 can extend into the receiving chamber 241 and extend into the interior of the second shell 21 through the wire entry through hole 212. The lamp device 100 in this embodiment also includes a glue potting sealant. When the wire of the first lighting lamp 10 is electrically connected to the electrical component inside the second shell 21, the glue potting sealant can be filled into the receiving chamber 241 through the opening of the receiving groove to seal the wire entry through hole 212 to prevent water vapor or liquid water from entering the interior of the second shell 21. In this embodiment, a plurality of glue potting holding portions 24 may be provided, and the plurality of glue potting holding portions 24 and the plurality of wire entry through holes 212 mentioned above are provided in a one-to-one correspondence.

[0047] See also Figure 8 In this embodiment, a matching through hole 242 is provided on the glue potting holding portion 24. In this embodiment, the matching through hole 242 is arranged opposite to the wire entry through hole 212, and the axis of the matching through hole 242 coincides with the axis of the wire entry through hole 212. Under the arrangement of this embodiment, the wire can pass through the matching through hole 242, the accommodating cavity 241 and the wire entry through hole 212 in sequence to extend into the interior of the second shell 21, and the extension direction of the wire of the first lighting lamp 10 is substantially the same as the axial direction of the wire entry through hole 212, which can reduce the bending of the wire and avoid the disconnection or instability of the electrical connection relationship of the electrical components connected to the two ends of the wire due to the bending of the wire. The wire can extend into the accommodating cavity 241 without passing through the opening of the accommodating cavity 241, which is convenient for filling the glue potting seal.

[0048] It should be understood that the first housing 11 of the first lighting lamp 10 in this embodiment may also be provided with the wire entry hole 212 and the glue potting holding portion 24 mentioned above. The specific structure may refer to the structure of the second lighting lamp 20 and will not be described again here.

[0049] See also Fig. 9 In this embodiment, the lamp device 100 further includes a mounting bracket 60, and the second illuminating lamp 20 is rotatably connected to the mounting bracket 60. The mounting bracket 60 can be installed in an application environment, for example, on a vehicle, a building facade, or other structures. In this embodiment, the mounting bracket 60 has two mounting ends 61 in its extension direction, and the two mounting ends 61 are arranged relatively spaced apart. Part of the structure of the second housing 21 of the second illuminating lamp 20 is located between the two mounting ends 61, and is rotatably connected to the two mounting ends 61, respectively, so that the second illuminating lamp 20 can rotate around the third axis N relative to the mounting bracket 60. In this embodiment, the extension direction of the third axis N is roughly the same as the length direction of the illuminating lamp. In actual application scenarios, the direction of the third axis N can be set in the horizontal direction, so that the second illuminating lamp 20 and other illuminating lamps can rotate around the horizontally set axis to adjust the lighting height of the lamp device 100.

[0050] See also Fig. 9 In this embodiment, the lamp device 100 further includes a dial 70, which is used to measure the rotation angle of the second illuminating lamp 20 relative to the mounting bracket 60. Specifically, the dial 70 is fixedly arranged on one mounting end 61 of the mounting bracket 60 (or the dial 70 is arranged on both mounting ends 61), and the center of the dial 70 coincides with the third axis N. An indicator mark (not shown in the figure) is arranged on the second housing 21 of the second illuminating lamp 20, and the indicator mark can correspond to the scale on the dial 70. In this embodiment, the movement trajectory of the indicator mark is roughly arranged around the local periphery of the scale on the dial 70, and the indicator mark can rotate around the third axis N to correspond to different scales, and different scales can represent the rotation angle of the second housing 21 relative to the mounting bracket 60. The user can fine-tune the second illuminating lamp 20 according to the dial 70, and can record the scale corresponding to the indicator mark for the next use of the lamp device 100.

[0051] In this embodiment, the dial 70 and the second housing 21 are each provided with a group of teeth (not shown in the figure) arranged around the third axis N, and the group of teeth on the dial 70 can mesh with the group of teeth on the second housing 21 to limit the rotation of the second illuminating lamp 20 relative to the mounting bracket 60. In some embodiments, the material of the dial 70 can be elastic plastic, which can make the group of teeth on the dial 70 deformable so that the dial 70 can rotate around the third axis N relative to the second housing 21, thereby adjusting the position relationship of the second illuminating lamp 20 relative to the mounting bracket 60.

[0052] The present embodiment provides a lamp device 100, wherein a first illuminating lamp 10 in the first lamp device 100 is provided with a rotation axis positioning member 40, and the elastic matching portion 411 of the rotation axis positioning member 40 can be engaged with the first anti-slip portion 311 of the connecting member 30, so as to limit the rotation of the first illuminating lamp 10 relative to the connecting member 30 and the second illuminating lamp 20. The elastic matching portion 411 with deformation ability can directly rotate around the first axis L relative to the connecting member 30 under the action of an external force, so that the first illuminating lamp 10 can rotate around the first axis L relative to the second illuminating lamp 20. Therefore, under the setting of the present embodiment, it is not necessary to disassemble the lamp device 100 in order to release the engagement limiting relationship between the elastic matching portion 411 and the first anti-slip portion 311, and the first illuminating lamp 10 can be directly pushed to adjust the position relationship of the first illuminating lamp 10 relative to the second illuminating lamp 20, and the operation is simple.
