DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] See also Figures 1 to 4 The present application provides an embedded lamp, including a lamp body 100 and a junction box 200. The lamp body 100 has a light-emitting component 110. The junction box 200 is used to connect the light-emitting component 110 and an external power source, specifically to achieve electrical connection through a wire. Generally, the lamp body 100 has a light-transmitting surface and a backlight supporting surface 1311. In this embodiment, the junction box 200 can be movably attached to the lamp body 100, and has a first position superimposed on the supporting surface 1311 and a second position separated from the supporting surface 1311, and the second position is lower than the first position, so as to achieve height adjustment of the lamp, so that the lamp can adapt to installation spaces of different heights.

[0038] See also Figure 3 In one embodiment, the junction box 200 is rotatable relative to the lamp body 100. For example, the junction box 200 can be rotated horizontally around a pivot axis 300 to achieve a change in the horizontal position of the junction box 200. It can also be rotated around a horizontal axis in a vertical plane.

[0039] For further information, see Figure 4 One of the junction box 200 and the lamp body 100 is fixedly connected to the pivot shaft 300, and the other is slidably matched with the pivot shaft 300. After the horizontal position of the junction box 200 is changed, the junction box 200 can be moved to the second position by sliding, that is, the height of the lamp can be adjusted.

[0040] For example, in one embodiment, the pivot shaft 300 is fixedly connected to the lamp body 100, and the junction box 200 slides with the pivot shaft 300. Taking the lamp body 100 as a reference, the support surface 1311 of the lamp body 100 is in the first position, and the junction box 200 can slide down to the second position.

[0041] See also Figure 5 In the illustrated embodiment, the free end of the pivot shaft 300 is provided with an anti-slip portion 310 for preventing the junction box 200 from being detached from the pivot shaft 300. The anti-slip portion 310 may be composed of a plurality of elastic claws 311 arranged along the circumferential direction. For example, the free end of the pivot shaft 300 is a four-petal structure, each petal is provided with an elastic claw 311, and each elastic claw 311 is in the form of an inverted tooth facing downward.

[0042] When installing the lamp, if the height difference between the suspended ceiling and the ceiling is large, the junction box 200 can be stacked on the lamp body 100 and embedded in the installation hole of the suspended ceiling. If the height difference between the suspended ceiling and the ceiling is small, the junction box 200 is rotated so that it is horizontally offset with the lamp body 100, and the junction box 200 is inserted into the suspended ceiling through the installation hole in a side position, leaving space for the lamp body 100 to be embedded, and then the lamp body 100 is embedded in the suspended ceiling. Due to the limitation of the height difference, the junction box 200 will automatically slide to a suitable second position based on the lamp body 100.

[0043] In addition, to facilitate wiring with the light emitting assembly 110 , the pivot shaft 300 has a channel for threading the wire.

[0045] Furthermore, one end of the pivot shaft 300 is fixedly connected to the cover shell 130, and the other end passes through the junction box 200 to slide with it. Taking the lamp body 100 as a reference, the junction box 200 has a first position superimposed on the support surface 1311 of the cover shell 130, and a second position that is separated from the support surface 1311 by rotation and sliding in turn.
