In the present embodiment, the first connection portion is provided with three sleeves, the second connection portion is provided with two sleeves, and the sleeves of the first connection portion and the sleeves of the second connection portion are embedded with one another in a crossed manner, which increases the contact area between the sleeves of the first connection portion and the second connection portion, and increases the rotation damping of the first connection portion and the second connection portion rotating around the rotating shaft, so that when three-dimensional assembling is performed on a plurality of lamp units, a three-dimensional stereoscopic shape can be maintained persistently and stably, thereby achieving an excellent three-dimensional assembling effect.

By further providing gaskets between the ends of the rotating shaft and the outermost sleeves of the first connection portion, the rotation damping of the first connection portion and the second connection portion rotating around the rotating shaft can be further increased, so that when three-dimensional assembling is performed on a plurality of lamp units, a three-dimensional stereoscopic shape can be further stably maintained.

By means of the snap-fit connection between connectors and connection ports, secure connection between the lamp units is achieved. For example, due to secure snap-fit connection between connectors and connection ports, when planar assembling is performed on lamp units, first, all lamp units requiring planar assembling may be connected in a snap-fit manner to form a desired planar pattern on a table top for example, and then the assembled planar pattern is mounted to a predetermined position, for example, a wall surface. In this process, an operator does not need to repeatedly climb a ladder or the like to assemble and mount the lamp units, so that the assembling and mounting operations of the lamp units are easier, increasing the working efficiency.

By means of the screw holes provided on the connectors, the lamp units can be suspended to a predetermined position by using screws passing through the screw holes, thereby stabilizing the connection between the lamp units and the predetermined position (e.g., a wall surface). In addition, as the hinge structure of the connector can maintain a stable predetermined angle between the first connection portion and the second connection portion, after the planar pattern formed by assembling the lamp units is fixed to the predetermined position by using screws, the angle between the first connection portion and the second connection portion on each lamp unit at the edges of the planar pattern can be adjusted, so as to hide the screws behind the planar pattern, thereby improving the aesthetic appearance of the assembled lamp units.

In accordance with another embodiment of the present disclosure, a lamp system is provided. FIG. 6 shows a block diagram of a lamp system according to another embodiment of the present disclosure. FIG. 7a and FIG. 7b show an effect diagram of a lamp system according to another embodiment of the present disclosure, in which FIG. 7a is a stereoscopic assembling effect diagram of lamp units, and FIG. 7b is a planar assembling effect diagram of lamp units. Hereinafter, the lamp system according to another embodiment of the present disclosure is described in combination with FIGS. 6-7.

As shown in FIG. 6, the lamp system 20 comprises a plurality of lamp units 10, each lamp unit comprising: a lamp panel; a connector, the connector comprising: a rotating shaft; and a first connection portion and a second connection portion, the first connection portion and the second connection portion being sleeved on the rotating shaft in a hinge form and being rotatable relative to each other around the rotating shaft; and connection ports, provided on the lamp panel and configured to be detachably snap-fitted with one of the first connection portion and the second connection portion, wherein the plurality of lamp units are connected to one other by means of the connectors.

It should be noted here that the specific structure of each lamp unit 10 in the lamp system 20 is completely the same as the structure described in conjunction with FIGS. 1-5. In order to avoid obscuring the present disclosure due to excessive description, the specific structure of the lamp unit 10 will not be repeated herein.

In the lamp system 20, by adjusting the angle between the first connection portion and the second connection portion of each lamp unit, for example, a stereoscopic assembling effect of the lamp units as shown in FIG. 7a and a planar assembling effect of the lamp units as shown in FIG. 7b can be achieved.

In the stereoscopic assembling of lamp units as shown in FIG. 7a, the connectors of the lamp units have enhanced rotation damping and a secure snap-fit connection exists between the connectors and the connection ports, and thus the angles between the lamp units can be adjusted as required to obtain a desired three-dimensional stereoscopic shape, and the three-dimensional stereoscopic shape can be maintained persistently and stably at the same time.

In the planar assembling of lamp units as shown in FIG. 7b, the connectors may be first inserted into the connection ports of the lamp units on a table top for example, and all lamp units (for example, four lamp units) requiring planar assembling are connected in a snap-fit manner to form a desired planar pattern, for example, a triangle; and then screws S may be used to pass through screw holes on the first connection portions or the second connection portions on the edge of the assembled planar pattern, so as to fix the planar pattern to a predetermined position, for example, a wall surface. As the hinge structures of the connectors are firm and reliable, the outermost lamp units can be fixed via screws to suspend the whole assembled planar pattern; and the hinge structures can rotate, and the screws S can be hidden behind the planar pattern, thereby improving the aesthetic appearance of the assembled lamp units.

The lamp system according to another embodiment of the present disclosure can achieve a stable three-dimensional stereoscopic shape and/or convenient planar assembling, so that the light-emitting patterns formed after the lamp units are assembled are more abundant, the light-emitting effect of the lamp units is improved, and the planar assembling of the lamp units is more convenient.

In the embodiments of the present disclosure, the description of each embodiment has its own emphasis. For the part not detailed in a certain embodiment, please refer to the relevant description in other embodiments.

The content above only relates to preferred embodiments of the present disclosure. It should be noted that for a person of ordinary skill in the art, several improvements and modifications can also be made without departing from the principle of the present disclosure, and these improvements and modifications shall also be considered as within the scope of protection of the present disclosure.
