Abstract
Description
Technical Field
[0001] This application relates to the field of lighting technology, and in particular to a lighting fixture. Background Technology
[0002] Lighting fixtures provide illumination for outdoor construction, camping, or office work. They typically consist of a bracket and a lamp holder, with the bracket usually constructed as a thin, straight cylinder. To match the bracket, the lamp holder is also made long and thin, resulting in structural instability when the fixture is in operation, making it prone to tipping over and causing the lamp holder to break. Utility Model Content
[0003] Therefore, it is necessary to provide a lighting fixture that addresses the problem of unstable structure in current lighting fixtures.
[0004] This application provides a lighting fixture, which includes a body, a connecting frame, and a lamp head assembly. The connecting frame includes a first arm and a second arm. The first arm is connected to the body, and at least a portion of the structure of the first arm is located circumferentially outside the body. The second arm is rotatably connected to the end of the first arm away from the body about a pitch axis, so as to be upright and prone relative to the body. The length direction of the second arm intersects the pitch axis, and the second arm can rotate to a position where its orthographic projection along the length direction of the body is located within the end face of the body. The lamp head assembly is rotatably connected to the second arm about the length direction of the second arm.
[0005] In one embodiment, the second arm can rotate around the pitch axis to a position where it is in contact with the first arm, and in this state, the light-emitting side of the lamp head assembly faces away from the body; the second arm can rotate around the pitch axis to a position where the length direction of the second arm is parallel to the length direction of the first arm, and in this state, the projection of the lamp head assembly along the length direction of the body is located outside the end face of the body, and the light-emitting side of the lamp head assembly faces the side where the body is located.
[0006] In one embodiment, the lamp head assembly includes a first lamp head and a second lamp head, which are located on opposite sides of the second arm along the pitch axis. The first lamp head and the second lamp head are rotatably connected to the second arm about its length direction to unfold and retract. When the lamp head assembly is in the unfolded position, the light-emitting sides of the first lamp head and the second lamp head face the same side. When the lamp head assembly is in the retracted position, the first lamp head and the second lamp head abut back to back, so that the light-emitting sides of the first lamp head and the second lamp head are arranged opposite to each other.
[0007] In one embodiment, when the lamp head assembly is in the retracted position and the second arm is in an upright position, at least a portion of the structure of the first lamp head and at least a portion of the structure of the second lamp head are projected along the length of the body into the end face of the body.
[0008] In one embodiment, the first lamp head is rotatably connected to the second arm about a first rotation axis, and the second lamp head is rotatably connected to the second arm about a second rotation axis. The first rotation axis and the second rotation axis are parallel and both are perpendicular to the pitch axis.
[0009] In one embodiment, the connecting frame further includes a damping element, the number of which is one or more; the damping element is connected between the first arm and the second arm, so that the first arm and the second arm are in damped rotational engagement; and / or, the damping element is connected between the lamp head assembly and the second arm, so that the lamp head assembly and the second arm are in damped rotational engagement.
[0010] In one embodiment, the damping element is configured as a damping sleeve, and the end of the first arm away from the fuselage has an insertion hole extending along the pitch axis. The connecting frame also includes an adapter shaft, which is rotatably engaged with the insertion hole and connected to the second arm. The damping sleeve is fixedly sleeved on the adapter shaft and located inside the insertion hole, and the damping sleeve is in close contact with the inner wall of the insertion hole.
[0011] In one embodiment, the first arm includes a connecting plate and an outer cantilever. The connecting plate is located at the end of the body, one end of the outer cantilever is connected to the connecting plate, and the other end extends outward in a circumferential direction from the body and has the insertion hole. The second arm can rotate to a position that fits against the connecting plate.
[0012] In one embodiment, the outer cantilever includes a collar located at one end away from the connecting plate, and a plurality of collars are coaxially spaced along the pitch axis, with the insertion hole extending from the plurality of collars; the second arm includes a connecting ring at one end, the connecting ring being located within the interval between the collars and coaxially arranged with the collars, and the outer wall of the adapter shaft and the inner wall of the connecting ring having a protruding transmission part on one side and a transmission groove recessed along the pitch axis on the other side; when the adapter shaft is axially inserted into the collar and the connecting ring, the transmission part engages with the transmission groove for transmission.
[0013] In one embodiment, the first arm has a first wiring channel that communicates with the socket and the interior of the body. The adapter shaft is hollow and has a wire passage. The outer periphery of the adapter shaft also has a first wire opening. The first wiring channel, the socket, the wire passage, and the first wire opening are interconnected. The second arm includes a connecting ring at the end. The second arm has a second wiring channel that communicates with the interior of the lamp head assembly. The connecting ring is sleeved on the adapter shaft and is drively connected to the adapter shaft. The inner wall of the connecting ring has a second wire opening that communicates with the second wiring channel. The second wire opening is aligned with the first wire opening.
[0014] In one embodiment, the damping element is configured as a damping shaft, the damping shaft including an axially distributed first segment and a second segment, the first segment and the second segment being damped and rotatably engaged, while maintaining a fixed relative angular position when not subjected to a driving force; the lamp head assembly includes a connecting shaft, one end of which is rotatably connected to the second arm, and the other end of which is axially driven connected to the first segment, the second segment being fixedly connected to the second arm.
[0015] In one embodiment, the body includes a housing, and the lighting fixture further includes at least one of the following: the body further includes a connecting portion located at one end of the housing opposite to the lamp head assembly, the connecting portion being used to connect and fix to the mounting structure by at least one of magnetic connection, plug-in connection, snap-fit connection, and threaded connection; the body further includes a light-emitting element disposed within the housing, the light-emitting side of the light-emitting element facing the housing, and at least a region of the housing being configured to be light-transmitting; the body further includes an energy storage element and a control board, both of which are disposed within the housing, the energy storage element being electrically connected to the control board, and the control board being electrically connected to the lamp head assembly.
[0016] In the aforementioned lighting fixture, the lamp head assembly is located on the second arm. The first arm is connected to the fuselage and extends outward relative to the fuselage. The second arm is connected to the end of the first arm furthest from the fuselage, such that the second arm and the lamp head assembly mounted on the second arm are located outward relative to the fuselage. Therefore, when the second arm is tilted relative to the first arm and the fuselage around its pitch axis, the projection of the second arm can be located within the fuselage end face, allowing the lamp head assembly on the second arm to be closer to the fuselage. This provides illumination while making the overall structure of the lighting fixture more compact. Furthermore, the lamp head assembly is rotatably connected to the second arm. When the second arm is tilted, the lamp head assembly can be rotated relative to the second arm to achieve the desired illumination angle. Moreover, when the second arm is tilted relative to the first arm and the fuselage around its pitch axis, the second arm can be positioned relatively away from the fuselage, further expanding the illumination angle of the lamp head assembly. Therefore, this arrangement allows the lighting fixture to balance structural stability with providing sufficient illumination. Attached Figure Description

[0038] See Figures 1 to 3 , Figure 1 An isometric schematic diagram of a lighting fixture provided in one embodiment of this application is shown. Figure 2 for Figure 1 The diagram shown is an isometric view of the lighting fixture with the second arm in a prone position.

[0039] An embodiment of this application provides an improved lighting fixture 10, which includes a body 100, a connecting frame 200, and a lamp head assembly 300. One end of the connecting frame 200 is connected to the body 100, and the lamp head assembly 300 is located at the other end of the connecting frame 200, providing illumination. The connecting frame 200 includes a first arm 210 and a second arm 220. The first arm 210 is connected to the body 100, and at least a portion of the structure of the first arm 210 is located circumferentially outside the body 100. The second arm 220 is rotatably connected to the end of the first arm 210 away from the body 100 about a pitch axis S, allowing it to be upright or prone relative to the body 100. The length direction of the second arm 220 intersects the pitch axis S. When the second arm 220 is in the prone position, its orthographic projection along the length direction of the body 100 lies within the end face of the body 100. The lamp head assembly 300 is rotatably connected to the second arm 220 about the length direction of the second arm 220.
[0040] In the aforementioned lighting fixture 10, the lamp head assembly 300 is disposed on the second arm 220. The first arm 210 is connected to the fuselage 100 and extends outward in a circumferential direction relative to the fuselage 100. The second arm 220 is connected to the end of the first arm 210 away from the fuselage 100, such that the second arm 220 and the lamp head assembly 300 disposed on the second arm 220 are located circumferentially outward relative to the fuselage 100. Thus, when the second arm 220 is tilted about the pitch axis S relative to the first arm 210 and the fuselage 100, the projection of the second arm 220 can be located within the end face of the fuselage 100, thereby allowing the lamp head assembly 300 disposed on the second arm 220 to be closer to the location of the fuselage 100. This makes the overall structure of the lighting fixture 10 more compact while providing illumination. Furthermore, the lamp head assembly 300 is rotatably connected to the second arm 220. When the second arm 220 is in a prone position, the lamp head assembly 300 can be rotated relative to the second arm 220 to meet the required lighting angle. Further, when the second arm 220 is tilted relative to the first arm 210 and the fuselage 100 around the pitch axis S, the second arm 220 can move relatively away from the fuselage 100, further enriching the lighting angle of the lamp head assembly 300. Therefore, this arrangement allows the lighting fixture 10 to achieve both structural stability and sufficient lighting effect.
[0041] It is easy to understand that the second arm 220's upright and prone positions relative to the first arm 210 and the fuselage 100 are relative states. That is, at various positions during the rotation of the second arm 220 around the pitch axis S, the second arm 220 in the upright position is closer to the end face of the fuselage 100 that connects to the first arm 210 compared to the second arm 220 in the prone position.
[0042] As one example, such as Figure 2 The second arm 220 is shown in a prone position when it is in contact with the first arm 210. That is, the second arm 220 can rotate around the pitch axis S to a position where it is in contact with the first arm 210. In this state, the first arm 210 and the body 100 provide a supporting base for the second arm 220, improving the positional stability of the second arm 220 and the lamp head assembly 300 mounted on the second arm 220. Of course, the second arm 220 in the prone position can also be in contact with the end face of the body 100, or simultaneously with both the end face of the body 100 and the first arm 210. Furthermore, in this state, the light-emitting side 301 of the lamp head assembly 300 can face away from the body 100, allowing the body 10 to be held horizontally, thus enabling the lighting fixture 10 to be used as a handheld flashlight.
[0043] As one example, such as Figure 1 and Figure 3 The length direction of the second arm 220 is perpendicular to the length direction of the first arm 210, and the second arm 220 is in an upright position.
[0044] Of course, please see Figure 4 The second arm 220 can continue to rotate away from the first arm 210. The second arm 220 can rotate around the pitch axis S to a position where its length direction is parallel to the length direction of the first arm 210, at which point the second arm 220 is in another prone position. In this state, the projection of the lamp head assembly 300 along the length direction of the body 100 is located outside the end face of the body 100, and the light-emitting side 301 of the lamp head assembly 300 faces the side where the body 100 is located. Therefore, the illumination provided by the lamp head assembly 300 is not obstructed by the body 100. At this time, the body 100 can be placed on a table or other supporting surface, allowing the lighting fixture 10 to be used as a table lamp.
[0045] With the first arm 210 and the second arm 220 in contact as a reference, the angle at which the second arm 220 rotates relative to the first arm 210 about the pitch axis S can be between 0° and 180°. For example, the rotation angle can be 30°, 60°, 90°, 120°, 150°, and 180°. Of course, the angle at which the second arm 220 rotates relative to the first arm 210 about the pitch axis S can also be configured to be larger, for example, the rotation angle can be between 0° and 270°.
[0046] Please continue reading. Figures 1 to 3 In one embodiment, the lamp head assembly 300 is rotatably connected to the second arm 220 about a rotation axis (i.e., the first rotation axis O1 and the second rotation axis O2 mentioned below). The rotation axis is parallel to the length direction of the second arm 220, that is, the rotation axis intersects the pitch axis S. In other words, in this embodiment, the lamp head assembly 300 can rotate relative to the second arm 220 about the rotation axis, and simultaneously, the lamp head assembly 300 can also rotate relative to the first arm 210 and the fuselage 100 about the pitch axis S with the second arm 220. That is, the lamp head assembly 300 can rotate about two intersecting axes, enriching the illumination angle of the lamp head assembly 300. Furthermore, the rotation axis can be configured to be perpendicular to the pitch axis S.
[0047] Please continue reading. Figures 1 to 3 In one embodiment, the lamp head assembly 300 includes a first lamp head 310 and a second lamp head 320, which are located on opposite sides of the second arm 220 along the pitch axis S. The first lamp head 310 and the second lamp head 320 are rotatably connected to the second arm 220 about its length, respectively, for unfolding and retracting. Figure 1 , Figure 2 and Figure 4When the lamp head assembly 300 is in the extended position, the light-emitting side 301 of the first lamp head 310 and the light-emitting side 301 of the second lamp head 320 face the same side. At the same power, the first lamp head 310 and the second lamp head 320 facing the same side enhance the lighting effect of the lighting fixture 10. When the lamp head assembly 300 is in the retracted position, the light-emitting side 301 of the first lamp head 310 and the second lamp head 320 are positioned opposite each other. At this time, the lighting areas of the first lamp head 310 and the second lamp head 320 have almost no overlap, thus the first lamp head 310 and the second lamp head 320 can provide a wider lighting area when working together. Furthermore, when the lamp head assembly 300 is in the retracted position, the first lamp head 310 and the second lamp head 320 abut against each other back-to-back, thereby causing the light-emitting side 301 of the first lamp head 310 and the light-emitting side 301 of the second lamp head 320 to be positioned opposite each other. The first lamp holder 310 and the second lamp holder 320 can also provide mutual support when they are back to back, further improving the structural stability of the lighting fixture 10 when it is illuminating.
[0048] Please see Figure 5 Combined Figures 1 to 3 When the lamp head assembly 300 is in the extended position, controlling the pitch angle of the second arm 220 around the pitch axis S allows adjustment of the light emission direction of the first lamp head 310 and the second lamp head 320. Furthermore, the first lamp head 310 and the second lamp head 320 are rotatably connected to the second arm 220, so they can rotate circumferentially around the second arm 220 without interference. Therefore, with the fuselage 100 as a reference, by flexibly adjusting the angles of the second arm 220 around the pitch axis S, the angles of the first lamp head 310 around the second arm 220, and the angles of the second lamp head 320 around the second arm 220, the illumination areas of the first lamp head 310 and the second lamp head 320 can cover a hemispherical area to fully meet lighting requirements. Regarding the aforementioned hemispherical area, for example… Figure 5 The upper hemispherical region shown is referenced to the fuselage 100.
[0049] Please see Figure 3 As one example, when the lamp head assembly 300 is in the retracted position and the second arm 220 is in the upright position, at least a portion of the structure of the first lamp head 310 and at least a portion of the structure of the second lamp head 320 are projected along the length of the fuselage 100 into the end face of the fuselage 100. That is to say, at this time, the first lamp head 310 and the second lamp head 320 are not only back to back, but also positioned above the end face of the fuselage 10, so that the various parts of the lighting fixture 10 are roughly distributed along the length of the fuselage 10, making the overall structure of the lighting fixture 10 more compact, coordinated, and less prone to tipping over.
[0050] It is easy to understand that when the lamp head assembly 300 is in the retracted position and the second arm 220 is in the upright position, the orthographic projections of the entire structure of the first lamp head 310 and the entire structure of the second lamp head 320 along the length direction of the fuselage 100 can both lie within the end face of the fuselage 100. Alternatively, only a portion of the structure of the first lamp head 310 may lie within the aforementioned end face, and only a portion of the structure of the second lamp head 320 may lie within the aforementioned end face.
[0051] Furthermore, the first lamp head 310 can be rotatably connected to the second arm 220 around the first rotation axis O1, and the second lamp head 320 can be rotatably connected to the second arm 220 around the second rotation axis O2. The first rotation axis O1 and the second rotation axis O2 are parallel and both perpendicular to the pitch axis S. That is, the rotation axis of the first lamp head 310 (i.e., the first rotation axis O1) is orthogonal to the revolution axis of the first lamp head 310 as it revolves with the second arm 220 (i.e., the pitch axis S), which facilitates the adjustment of the illumination area of the first lamp head 310. The rotation axis of the second lamp head 320 (i.e., the second rotation axis O2) is orthogonal to the revolution axis of the second lamp head 320 as it revolves with the second arm 220 (i.e., the pitch axis S), which also facilitates the adjustment of the illumination area of the second lamp head 320.
[0052] In one embodiment, the connecting frame 200 further includes a damping element, and the number of damping elements is one or more. The damping element is connected between the first arm 210 and the second arm 220, so that the first arm 210 and the second arm 220 are in damped rotational engagement. The damped rotational engagement means that the first arm 210 and the second arm 220 can maintain a fixed relative angular position when there is no pitch driving force, so as to stably provide illumination; the second arm 220 can rotate relative to the first arm 210 under the action of pitch driving force, thereby adjusting the illumination angle of the lamp head assembly 300.
[0053] In one embodiment, a damping element may also be connected between the lamp head assembly 300 and the second arm 220, enabling a damped rotational engagement between the lamp head assembly 300 and the second arm 220. That is, the first lamp head 310 and the second arm 220 can be configured for a damped rotational engagement, and the second lamp head 320 and the second arm 220 can also be configured for a damped rotational engagement. The damped rotational engagement means that the first lamp head 310 and the second arm 220 maintain a fixed relative angular position when not subjected to an opening / closing driving force, and the second lamp head 320 and the second arm 220 also maintain a fixed relative angular position when not subjected to an opening / closing driving force. The first lamp head 310 and the second lamp head 320 can rotate relative to the second arm 220 under the action of an opening / closing driving force.
[0054] Please see Figures 6 to 8In one embodiment, the first arm 210 includes a connecting plate 211 and an outer cantilever 212. The connecting plate 211 is located at the end of the fuselage 100. One end of the outer cantilever 212 is connected to the connecting plate 211, and the other end extends circumferentially outward from the fuselage 100 to be rotatably connected to the second arm 220. Compared to the elongated outer cantilever 212, the connecting plate 211 can have a larger contact area with the fuselage 100. Therefore, configuring the first arm 210 to connect to the fuselage 100 via its connecting plate 211 can improve the stability of the connection. Figure 7 The second arm 220 can rotate to a position where it is in contact with the connecting plate 211, at which point the second arm 220 is in a prone position. It can be understood that the second arm 220 can also rotate to a position where it is in contact with the outer cantilever 212, and the second arm 220 can also rotate to a position where it is in contact with both the connecting plate 211 and the outer cantilever 212 simultaneously.
[0055] Please see Figures 6 to 8 In one embodiment, the damping element can be configured as a damping sleeve 240. A socket 213 is provided at the end of the first arm 210 away from the fuselage 100, extending along the pitch axis S. The socket 213 can be located at the end of the outer cantilever 212 away from the connecting plate 211; that is, one end of the outer cantilever 212 is connected to the connecting plate 211, and the other end extends circumferentially outward from the fuselage 100 and has the socket 213. The connecting frame 200 also includes a transition shaft 230, which rotatably engages with the socket 213 and connects to the second arm 220. The damping sleeve 240 is fixedly sleeved on the transition shaft 230 and located within the socket 213, with the damping sleeve 240 in close contact with the inner wall of the socket 213, so that the first arm 210 and the second arm 220 have a damping effect when rotating. In short, the damping element in this embodiment can be configured to provide a damping effect through friction. The damping sleeve 240 can be made of a flexible soft rubber material, such as silicone or rubber.
[0056] Please see Figures 6 to 8 In one embodiment, the damping sleeve 240 includes multiple protruding mating portions 241 on its outer periphery, which are used to make tight contact with the inner wall of the insertion hole 213. This application configures the protruding mating portions 241 to contact the inner wall of the insertion hole 213, thereby reducing the contact area between the damping sleeve 240 and the hole wall of the insertion hole 213. This reduces the likelihood of excessive friction causing the first arm 210 and the second arm 220 to be unable to rotate smoothly, and also reduces noise caused by friction. In this embodiment, the damping effect can be adjusted by flexibly configuring the protrusion of the mating portions 241 and the number of mating portions 241.
[0057] Furthermore, the inner wall of the insertion hole 213 may be recessed with multiple mating grooves 213a, which engage with the mating part 241 to improve the stability of the relative position of the second arm 220 and the first arm 210. Since the damping sleeve 240 is elastic, rotating the damping sleeve 240 allows the mating part 241 to easily disengage from the mating groove 213a. Multiple mating parts 241 may be spaced apart in the outer peripheral region of the damping sleeve 240 in a circumferential direction around the pitch axis S. The number of mating grooves 213a may also be multiple, spaced apart in a circumferential direction around the pitch axis S on the inner wall of the insertion hole 213.
[0058] Please see Figure 8 , Figure 9 Combined Figure 6 In one embodiment, the outer cantilever 212 includes a collar 214 located at the end away from the connecting disc 211. Multiple collars 214 are coaxially spaced along the pitch axis S, and insertion holes 213 extend from and are formed in the multiple collars 214. The second arm 220 includes a connecting ring 221 at its end, which is fitted onto the adapter shaft 230 and is driveably connected to it. The connecting ring 221 is located within the intervals between the collars 214 and is coaxially arranged with the collars 214. The outer wall of the adapter shaft 230 and the inner wall of the connecting ring 221 each include a protruding transmission portion (not shown in the figure, the same below), and the other has a recessed transmission groove 231 along the pitch axis S. When the adapter shaft 230 is axially inserted into the collars 214 and the connecting ring 221, the transmission portion engages with the transmission groove 231 for transmission. Therefore, while axially inserting the adapter shaft 230 into the collar 214 and the connecting ring 221, the transmission part can be inserted into the transmission groove 231 to form a transmission engagement, thus reducing the installation difficulty of the adapter shaft 230.
[0059] Furthermore, the number of collars 214 can be two, with the connecting ring 221 located within the interval between the two collars 214. Of course, the number of collars 214 can also be three or more, and correspondingly, there can be multiple connecting rings 221.
[0060] Please see Figure 8 In one embodiment, the damping sleeve 240 and the adapter shaft 230 can also be fixedly connected by axial insertion. For example, the adapter shaft 230 includes a toothed portion 232, which is located at one end of the adapter shaft 230, and the damping sleeve 240 has an internal toothed groove (not shown in the figure, the same below). When the damping sleeve 240 is axially fitted onto the adapter shaft 230, the internal toothed groove and the toothed portion 232 engage and nest to form a transmission connection. Furthermore, a threaded fastener 260 can be configured to lock the damping sleeve 240 and the adapter shaft 230 from the end face.
[0061] It should be noted that the damping element is not limited to being constructed as the damping sleeve 240 as described above. For example, please refer to... Figure 10 and Figure 11 In one embodiment, the damping element can also be configured as a damping shaft 250, which includes a first segment 251 and a second segment 252 axially distributed. The first segment 251 and the second segment 252 are in damped rotational engagement and maintain a fixed relative angular position when not subjected to a driving force. Taking the damping shaft 250 connected between the lamp head assembly 300 and the second arm 220 as an example: the lamp head assembly 300 includes a connecting shaft that extends along the length direction of the second arm 220. One end of the connecting shaft is rotatably connected to the second arm 220, and the other end is axially driven connected to the first segment 251. The second segment 252 is fixedly connected to the second arm 220. That is, the lamp head assembly 300 can achieve damped rotation by rotating with the second arm 220 through the damping shaft 250 and its own connecting shaft.
[0062] For the first lamp head 310, the damping shaft 250 connecting the first lamp head 310 and the second arm 220 is designated as the first damping shaft 250a, and the connecting shaft of the first lamp head 310 is designated as the first connecting shaft 311. The first connecting shaft 311 and the first segment 251 of the first damping shaft 250a are inserted along the first rotation axis O1 to form a transmission fit. The second arm 220 is provided with a first cavity 224. Along the first rotation axis O1, one of the two opposing cavity walls of the first cavity 224 is provided with a first adapter hole 224a, and the other is provided with a first positioning hole 224b. The first connecting shaft 311 and the first damping shaft 250a are both located in the first cavity 224, and the end of the first connecting shaft 311 away from the first damping shaft 250a is rotatably fitted with the first adapter hole 224a, while the end of the second segment 252 of the first damping shaft 250a away from the first connecting shaft 311 is positioned fitted with the first positioning hole 224b. Therefore, when the first lamp head 310 is subjected to the opening and closing driving force, the first connecting shaft 311 drives the first segment 251 to rotate, while the second segment 252 is fixed relative to the second arm 220, so that the damping effect between the first segment 251 and the second segment 252 is reflected in the rotational movement of the first lamp head 310 relative to the first arm 210.
[0063] For the second lamp head 320, the damping shaft 250 connecting the second lamp head 320 and the second arm 220 is designated as the second damping shaft 250b, and the connecting shaft of the second lamp head 320 is designated as the second connecting shaft 321. The second connecting shaft 321 and the first section 251 of the second damping shaft 250b are inserted along the second rotation axis O2 to form a transmission fit. The second arm 220 is provided with a second cavity 225. Along the second rotation axis O2, one of the two opposing cavity walls of the second cavity 225 has a second adapter hole 225a, and the other has a second positioning hole 225b. The second connecting shaft 321 and the second damping shaft 250b are both located in the second cavity 225. The end of the second connecting shaft 321 away from the second damping shaft 250b is rotatably fitted with the second adapter hole 225a, and the end of the second section 252 of the second damping shaft 250b away from the second connecting shaft 321 is positioned fitted with the second positioning hole 225b. Therefore, when the second lamp head 320 is subjected to the opening and closing driving force, the second connecting shaft 321 drives the first segment 251 to rotate, while the second segment 252 is fixed relative to the second arm 220, so that the damping effect between the first segment 251 and the second segment 252 is reflected in the rotational movement of the second lamp head 320 relative to the second arm 220.
[0064] Please see Figure 10 In one embodiment, the damping shaft 250 has flat sections at both opposite ends for engaging with the connecting shaft and the second arm 220.
[0065] It should be emphasized that the damping shaft 250 can also be connected between the first arm 210 and the second arm 220 to provide a damping effect. In this case, the connection structure between the first arm 210 and the second arm 220 can be adaptively adjusted according to the connection structure between the second arm 220 and the lamp head assembly 300. Similarly, the damping sleeve 240 can also be connected between the second arm 220 and the lamp head assembly 300 to provide a damping effect. In this case, the connection structure between the second arm 220 and the lamp head assembly 300 can be adaptively adjusted according to the connection structure between the first arm 210 and the second arm 220.
[0066] Please see Figure 12 In one embodiment, the body 100 includes a housing 110, an energy storage component 120, and a control board 130. Both the energy storage component 120 and the control board 130 are disposed within the housing 110. The energy storage component 120 provides electrical energy to the lamp holder assembly 300. The energy storage component 120 is electrically connected to the control board 130, and the control board 130 is electrically connected to the lamp holder assembly 300. Furthermore, the connecting frame 200 has a wiring channel for wiring to electrically connect the control board 130 located within the body 100 and the lamp holder assembly 300 located on the second arm 220.
[0067] Please continue reading. Figure 13 Combined Figure 8In one embodiment, the first arm 210 has a first wiring channel 210a, which communicates with the insertion hole 213 and the interior of the body 100. The adapter shaft 230 is hollow and has a wire passage 233. A first wire opening 234 is also provided on the outer periphery of the adapter shaft 230. The first wiring channel 210a, insertion hole 213, wire passage 233, and first wire opening 234 are interconnected. The second arm 220 has a second wiring channel 220a, which communicates with the interior of the lamp holder assembly 300. The inner wall of the connecting ring 221 has a second wire opening 221a that communicates with the second wiring channel 220a, and the second wire opening 221a is aligned with the first wire opening 234. It is understood that after the transmission part is inserted into the transmission groove 231, the second wire opening 221a is aligned with the first wire opening 234. Because the adapter shaft 230 and the second arm 220 are driven together and rotate synchronously, the second wire port 221a can also maintain alignment with the second wire port 221a during the relative rotation of the second arm 220. In this embodiment, the wiring channel includes a first wiring channel 210a, a socket 213, a wire passage 233, a first wire port 234, a second wire port 221a, and a second wiring channel 220a connected in sequence. The wire can pass through the first wiring channel 210a, the socket 213, the wire passage 233, the first wire port 234, the second wire port 221a, and the second wiring channel 220a in sequence from inside the body 100 to electrically connect with the lamp holder assembly 300.
[0068] like Figure 9 Furthermore, a third wire opening 235 is formed at the end of the adapter shaft 230 opposite to the toothed portion 232, and the third wire opening 235 communicates with the socket 213. Positioning the third wire opening 235 at the end of the adapter shaft 230 reduces disturbance to the wire at the third wire opening 235 caused by the rotation of the adapter shaft 230 within the socket 213, facilitating wire arrangement.
[0069] Please continue reading. Figure 8 In one embodiment, both ends of the socket 213 are in communication with the external environment to facilitate the installation of components such as the adapter shaft 230 and the damping sleeve 240. The connector 200 also includes two end caps 270, which are respectively fitted onto opposite ends of the socket 213 to seal the socket 213 and improve the waterproofness of the wire. The two end caps 270 are fitted onto the opposite end faces of the two outermost rings 214 to seal the socket 213 and improve the waterproofness of the wire.
[0070] Please refer to this again. Figure 13 In one embodiment, the first arm 210 includes a first cover plate 215 and a first base frame 216. The first base frame 216 is hollowed out, and the first cover plate 215 covers one side of the first base frame 216 to enclose and form the aforementioned first wiring channel 210a. (Combined with...) Figure 1It is easy to understand that the portion of the first cover plate 215 and the first base frame 216 located on the end face of the fuselage 100 is the aforementioned connecting plate 211, and the portion of the first cover plate 215 and the first base frame 216 extending outward relative to the fuselage 100 is the aforementioned outer cantilever 212.
[0071] Please see Figure 14 Combined Figure 10 In one embodiment, the second arm 220 includes a second base frame 223 and a second cover plate 222. The second base frame 223 is hollowed out, and the second cover plate 222 covers one side of the second base frame 223. A connecting ring 221 is provided at one end of the second base frame 223 near the first arm 210.
[0072] Furthermore, the second arm 220 also includes a surrounding panel structure located within the second base frame 223. The surrounding panel structure includes a first surrounding panel 226 and a second surrounding panel 227. The first surrounding panel 226 encloses and forms the first cavity 224 as described above, with a first adapter hole 224a and a first positioning hole 224b both formed in the first surrounding panel 226. The second surrounding panel 227 encloses and forms the second cavity 225 as described above, with a second adapter hole 225a and a second positioning hole 225b both formed in the second surrounding panel 227. The first surrounding panel 226 and the second surrounding panel 227 are spaced apart to clamp together and form the second wiring channel 220a as described above.
[0073] like Figure 10 and Figure 11 Furthermore, the first connecting shaft 311 is hollow to form a first inlet channel 312, and the first inlet channel 312 forms a first opening 313 at the end of the first connecting shaft 311 that is in drive engagement with the first adapter hole 224a. The first opening 313 is connected to the second wiring channel 220a, so the wire can enter the first lamp holder 310 from the second wiring channel 220a through the first opening 313 and the first inlet channel 312.
[0074] Similarly, the second connecting shaft 321 is hollow to form a second inlet channel 322, and the second inlet channel 322 forms a second opening 323 at the end of the second connecting shaft 321 that is in drive engagement with the second adapter hole 225a. The second opening 323 is connected to the second wiring channel 220a, so the wire can enter the second lamp holder 320 from the second wiring channel 220a through the second opening 323 and the second inlet channel 322.
[0075] In other words, the cable routing also includes a first opening 313, a second opening 323, a first cable inlet 312, and a second cable inlet 322.
[0076] Please refer to it again. Figure 12In one embodiment, the housing 100 further includes a light-emitting element 140 disposed within the housing 110, with the light-emitting side of the light-emitting element 140 facing the housing 110. At least a region of the housing 110 is configured to be light-transmitting, allowing the light-emitting element 140 to provide ambient lighting effects through the housing 110. The light-emitting element 140 can be electrically connected to the control board 130.
[0077] Furthermore, the body 100 also includes a button 150, which is electrically connected to the control panel 130 and exposed through the housing 110 for interactive operation.
[0078] Please refer to Figure 12 In one embodiment, the housing 100 further includes a connecting portion 160 located at one end of the housing 110 opposite to the lamp head assembly 300. The connecting portion 160 is used to connect and fix to the mounting structure via at least one of the following connection methods: magnetic connection, plug-in connection, snap-fit connection, and threaded connection. For example, the mounting structure may be configured as a tripod, and the connecting portion 160 may be configured as a ferromagnetic component 161, which is magnetically connected to the mounting structure to fix the lighting fixture 10 relative to the mounting structure. The connecting portion 160 may also be configured as a threaded hole 162, which is used to connect with a threaded component of the mounting structure to fix the lighting fixture 10 relative to the mounting structure.
[0079] Furthermore, there can be multiple connecting parts 160, and the multiple connecting parts 160 can be configured with different connection forms so that the lighting fixture 10 can be adapted to different installation structures.
[0080] Please see Figure 13 In one embodiment, the first arm 210 further includes a first pad 217, which is disposed on the side of the first arm 210 that is used to fit with the second arm 220, so as to reduce the impact when the two fit together and improve the sealing of the connection between the first cover plate 215 and the first base frame 216.
[0081] Please see Figure 10 In one embodiment, the second arm 220 further includes a second pad 228, which is disposed on the side of the second arm 220 that is used to fit against the first arm 210, so as to reduce the impact when the two fit against each other and improve the sealing of the connection between the second cover plate 222 and the second base frame 223.
[0082] The embodiments of this application do not limit the specific construction of the first lamp head 310 and the second lamp head 320, and can be adapted to meet actual lighting needs. As one example, the first lamp head 310 and the second lamp head 320 can be constructed as floodlights, so that the first lamp head 310 and the second lamp head 320 have uniform light distribution characteristics to cover a large area.
[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
