[0034] Reference Figures 1 to 7 An eccentrically adjustable lamp includes: a base plate 100, an externally fixed structure 200, a movable plate 300, and an eccentric pivot 400. The externally fixed structure 200 is disposed on the base plate 100, and the movable plate 300 is positioned front-to-back with the base plate 100, configured to emit light. The eccentric pivot 400 is disposed between the base plate 100 and the movable plate 300. The eccentric pivot 400 is connected to the base plate 100 at a position off-center from its geometric center, and is also connected to the movable plate 300 at a position off-center from its geometric center. The movable plate 300 is rotatably connected to the base plate 100 via the eccentric pivot 400. The movable plate 300 can rotate to a position where its geometric center is opposite to the geometric center of the base plate 100, and also to a position where its geometric center is off-center from the geometric center of the base plate 100.

[0035] By employing a structure in which the movable disc 300 and the base disc 100 are eccentrically connected, the movable disc 300 can be rotated to a position where its geometric center is opposite to that of the base disc 100, thus forming a uniform luminaire. This luminaire provides the first type of lighting range and lighting pattern. When the lighting range and lighting pattern need to be adjusted, the movable disc 300 can be rotated to be eccentrically positioned relative to the base disc 100, thus forming the second type of lighting range and lighting pattern. Users can also adjust the specific angle and position of the movable disc 300 as needed, thereby creating even more lighting ranges and lighting patterns. The luminaire offers more adjustment options and is relatively easy to adjust.

[0036] In this embodiment, the base disk 100 is configured to emit light in a peripheral annular pattern, and the movable disk 300 is configured to emit light in a peripheral annular pattern. The movable disk 300 and the base disk 100 are arranged parallel to each other. The surface area of ​​the movable disk 300 is smaller than that of the base disk 100. The movable disk 300 can rotate to a position where it partially extends beyond the outer periphery of the base disk 100 and partially blocks the light-emitting part of the base disk 100. With the above structure, when the geometric centers of the movable disk 300 and the base disk 100 are opposite each other, a lighting structure with two concentric ring light sources can be formed, resulting in uniform and sufficient light emission with a regular and symmetrical light emission range. When the movable disk 300 is adjusted to a position where it partially extends beyond the outer periphery of the base disk 100, the movable disk 300 partially blocks the light-emitting part of the base disk 100, forming a lighting structure with a wider light emission range, and it can emit light to one side, thereby meeting specific lighting needs.

[0037] In this embodiment, the base disk 100 and the movable disk 300 are circular disk structures. The circular base disk 100 and the movable disk 300 are simple and easy to manufacture. Of course, it is conceivable that the base disk 100 and the movable disk 300 are not limited to a circular disk structure; for example, they could also be square disks, elliptical disks, triangular disks, etc., and the specific configuration can be determined according to the actual situation.

[0038] In this embodiment, the base disk 100 is provided with a first bearing 110, located off-center from the geometric center of the base disk 100. The movable disk 300 is provided with a second bearing 310, also located off-center from the geometric center of the movable disk 300. The first bearing 110 has a first connecting hole 111, and the second bearing 310 has a second connecting hole 311. An eccentric pivot 400 passes through both the first and second connecting holes 111 and 311, respectively. The eccentric pivot 400 is circumferentially fixed to the second connecting hole 311 and pivotally engaged with the first connecting hole 111. In some embodiments, the eccentric pivot 400 may also be circumferentially fixed to the first connecting hole 111 and pivotally engaged with the second connecting hole 311. This structure provides a simple, easy-to-assemble, and smooth-operating rotatable connection between the base disk 100 and the movable disk 300. It is conceivable that in some embodiments, the base disk 100 and the movable disk 300 are not limited to being connected by pivot through the structure described above. In the art, there are many ways to connect two components by pivot, and those skilled in the art can configure it according to the actual situation.

[0039] In one embodiment, the second connecting hole 311 can be set as a non-circular hole, and the part of the eccentric pivot 400 that mates with the second connecting hole 311 can be adapted to the shape of the second connecting hole 311, thereby achieving circumferential positioning and fixing. Of course, in some embodiments, the circumferential positioning and fixing between the shaft and the hole can also be achieved by using a key connection.

[0040] In this embodiment, a positioning ring 500 is provided between the first bearing seat 110 and the second bearing seat 310. The positioning ring 500 is sleeved on the eccentric pivot 400, and the eccentric pivot 400 is provided with a clamping structure that clamps the positioning ring 500 between the first bearing seat 110 and the second bearing seat 310. With the above structure, friction positioning can be achieved by clamping the positioning ring 500, thereby ensuring that the movable disk 300 is not easily loosened.

[0041] In this embodiment, the clamping structure consists of flanges and nuts (not shown in the attached diagram) at both ends of an eccentric pivot 400. The nuts are threaded onto the eccentric pivot 400. The nuts and flanges clamp the first bearing seat 110 and the second bearing seat 310. When the nuts are tightened, the first bearing seat 110 and the second bearing seat 310 clamp the positioning ring 500. Of course, it is conceivable that the clamping structure is not limited to the above-described implementation. For example, the clamping structure could consist of nuts threaded onto both ends of the eccentric pivot 400, thereby clamping the first bearing seat 110 and the second bearing seat 310 together. It is understood that the clamping structure can also be other structures, such as flanges and rivet joints at both ends of the eccentric pivot 400. During assembly, the rivet joints, together with the flanges, clamp the first bearing seat 110 and the second bearing seat 310. It should be noted that there are many other implementations in the art for structures that drive two components to clamp one component, and those skilled in the art can configure them according to actual conditions.

[0042] In this embodiment, the eccentric pivot 400 is a hollow shaft, which allows the power supply line to pass through the hollow cavity.

[0043] In this embodiment, the base disk 100 includes a first main shell 120, a first light-transmitting ring 130, and a first light-emitting source. The first light-transmitting ring 130 is disposed on the outer periphery of the first main shell 120, and the first light-emitting source is disposed on the first main shell 120 and configured to emit light towards the inner peripheral surface of the first light-transmitting ring 130. The movable disk 300 includes a second main shell 320, a second light-transmitting ring 330, and a second light-emitting source. The second light-transmitting ring 330 is disposed on the outer periphery of the second main shell 320, and the second light-emitting source is disposed on the second main shell 320 and configured to emit light towards the inner peripheral surface of the second light-transmitting ring 330. Using the above structure, the base disk 100 and the movable disk 300 can form a peripheral ring-shaped light emission, and light can be emitted through the light-transmitting ring, resulting in uniform light emission.

[0044] In this embodiment, the first main shell 120 includes a first shell 121 and a second shell 122, which are connected to each other. A first light-transmitting ring 130 is sandwiched between the periphery of the first shell 121 and the periphery of the second shell 122. The second main shell 320 includes a third shell 321 and a fourth shell 322, which are connected to each other. A second light-transmitting ring 330 is sandwiched between the periphery of the third shell 321 and the periphery of the fourth shell 322. Using the above structure, the light-transmitting ring can be fixed in a simple way. It is conceivable that in some embodiments, the light-transmitting ring is not limited to the above structure; for example, it can be fixed using fasteners. The specific configuration can be adjusted according to the actual situation.

[0045] In the embodiments, the first shell 121 and the second shell 122, and the third shell 321 and the fourth shell 322 can be fixed to each other by screws. Of course, in some embodiments, the first shell 121 and the second shell 122, and the third shell 321 and the fourth shell 322 can also be connected to each other by a snap-fit ​​structure, a snap-fit ​​structure or a riveting structure. The specific configuration can be made according to the actual situation.

[0046] In this embodiment, the first shell 121 and the first light-transmitting ring 130 are mutually positioned and fitted together by a first positioning structure. A first annular plate 1211 is provided on the surface of the first shell 121 near the second shell 122. The first annular plate 1211 and the inner circumferential surface of the first light-transmitting ring 130 are spaced apart and opposite each other, forming a first mounting groove 123 between them. A first light source is disposed in the first mounting groove 123, and the second shell 122 covers the opening of the first mounting groove 123. When assembling the base plate 100, the first light-transmitting ring 130 can be first installed on the first shell 121 using the first positioning structure to achieve mutual positioning. The first light source can be installed in the first mounting groove 123. After installing the second shell 122, the first light source is enclosed in the space formed between the first mounting groove 123 and the second shell 122. This structure facilitates the assembly of the base plate 100.

[0047] In this embodiment, the third shell 321 and the second light-transmitting ring 330 are mutually positioned and fitted together by a second positioning structure. A second annular plate 3211 is provided on the surface of the third shell 321 near the fourth shell 322. The second annular plate 3211 and the inner circumferential surface of the second light-transmitting ring 330 are spaced apart and opposite each other, forming a second mounting groove 323 between them. A second light source is disposed in the second mounting groove 323, and the fourth shell 322 covers the opening of the second mounting groove 323. When assembling the movable disk 300, the second light-transmitting ring 330 can be first installed on the third shell 321 using the second positioning structure to achieve mutual positioning. The second light source can then be installed in the second mounting groove 323. After installing the fourth shell 322, the second light source is enclosed in the space formed between the second mounting groove 323 and the fourth shell 322. This structure facilitates the assembly of the movable disk 300.

[0048] In this embodiment, the first light source is a first LED strip, which forms a ring, with the light-emitting side of the first LED strip facing the inner circumferential surface of the first light-transmitting ring 130. The second light source is a second LED strip, which forms a ring, with the light-emitting side of the second LED strip facing the inner circumferential surface of the second light-transmitting ring 330. Of course, it is conceivable that the first and second light sources are not limited to LED strips; for example, they could also be strings of LED beads or other strip-shaped or ring-shaped light-emitting devices.

[0049] In this embodiment, the first positioning structure is a first annular positioning groove 131 formed on the end face of the first light-transmitting ring 130 near the first shell 121. The outer periphery of the first shell 121 is adapted to and disposed within the first annular positioning groove 131. The second positioning structure is a second annular positioning groove 331 formed on the end face of the second light-transmitting ring 330 near the third shell 321. The outer periphery of the third shell 321 is adapted to and disposed within the second annular positioning groove 331. The first and second positioning structures described above are simple in structure, easy to implement, and provide accurate positioning. It is conceivable that the first and second positioning structures can also adopt other structures, such as a pin structure or a positioning block structure for positioning, which can be configured according to the actual situation.

[0050] In this embodiment, the external fixing structure 200 is used to fix the base plate 100, thereby fixing the entire lamp fixture externally. The external fixing structure 200 specifically includes a connecting frame, which can be fixed to a wall or other surface via mounting holes and screws. The connecting frame has a snap-fit ​​or latching structure to cooperate with the base plate 100. When installing the lamp fixture, the connecting frame can be installed first, and then the base plate 100 can be connected to the connecting frame. Of course, in other embodiments, the external fixing structure 200 can also be other structures, such as mounting ears or mounting holes on the base plate 100. In this embodiment, the external fixing structure 200 can be located on the back side of the base plate 100, so that the installed structure is not exposed. It is understood that there are many other implementations in the art for fixing lamp fixtures to external surfaces, which will not be described in detail here.

[0051] In this embodiment, the eccentric adjustment lamp can be used as a wall lamp, and in some cases, it can also be used as a lamp for other purposes, such as a ceiling lamp, an outdoor lamp, etc.
