The advantage of this decoration technique is that it can hide facilities such as wires and pipes without damaging the original ceiling. At the same time, it can also improve indoor lighting, sound insulation, and heat insulation effects, and increase the aesthetics of the interior. In actual operation, various different materials can be used for stepped ceilings, such as gypsum boards, aluminum plates, steel plates, etc., so as to achieve different decoration effects.

[0003] The assembled stepped board light strip structure is a new architectural structure form based on the stepped ceiling. It consists of multiple layers of misaligned boards, with LED light strips embedded between the boards. This structure form is usually used for the exterior facade or interior decoration of buildings and can produce unique light and shadow effects. This structure form has the advantages of easy installation, light weight, energy saving, etc., so it has been widely used in the fields of architecture and interior design.

[0004] However, in the actual use process, the assembled stepped board light strip structure also has some disadvantages, mainly including the following aspects:

[0005] 1. High cost: The production of this structure form requires high-precision machine equipment and high-quality materials, so the cost is relatively high;

[0006] 2. Difficult maintenance: Since this structure has many components and the service life of accessory equipment such as light strips is relatively short, it needs to be maintained regularly, which is difficult;

[0041] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Embodiment 1: As Figures 1 to 5 shown, an assembled staggered floor board light strip structure mainly consists of a ceiling board 1, a keel 2, a staggered floor board 8, and a side board 10. The keel 2 is fixedly installed on the wall. In this embodiment, the cross-section of the keel 2 is in a shape of a capital "J", which can effectively ensure the structural strength of the keel 2 while enabling operations such as threading and wiring in the keel 2, ensuring the rational utilization of the space above the keel 2. To ensure the structural strength of the ceiling board 1 and reduce the probability of the ceiling board 1 detaching, the above-mentioned ceiling board 1 in this embodiment is fixed to the above-mentioned keel 2 through a fixing member 3. Specifically, since the above-mentioned keel 2 is in a shape of a capital "J", the ceiling board 1 can be directly fixedly connected to the horizontal part of the keel 2 through the fixing member 3. The fixing member 3 can be a screw or the like with a simple structure and high economic practicality. The above-mentioned staggered floor board 8 is connected to the above-mentioned ceiling board 1. The above-mentioned staggered floor board 8 includes an upper staggered floor board 8-1 and a lower staggered floor board 8-2. The above-mentioned upper staggered floor board 8-1 is connected to the above-mentioned ceiling board 1. A light strip structure is installed at the connection between the above-mentioned lower staggered floor board 8-2 and the above-mentioned upper staggered floor board 8-1, and the connection between the above-mentioned lower staggered floor board 8-2 and the above-mentioned upper staggered floor board 8-1 is realized through the above-mentioned light strip structure. The above-mentioned side board 10 is connected to the above-mentioned lower staggered floor board 8-2.

[0043] Specifically, the above-mentioned ceiling panel 1 is arranged in a plate shape as a whole. In order to realize the rapid disassembly and assembly between the above-mentioned upper staggered layer panel 8-1 and the ceiling panel 1, a positioning protrusion 1-1 is formed on the side end of the above-mentioned ceiling panel 1. The cross-section of the positioning protrusion 1-1 in this embodiment is arranged in a rectangular shape. Adaptively thereto, the above-mentioned upper staggered layer panel 8-1 has an upper staggered layer panel hanging portion 8-1-1, and the upper staggered layer panel hanging portion 8-1-1 is in the shape of a hook, or a rectangular groove adapted to the positioning protrusion 1-1 is formed at the upper staggered layer panel hanging portion 8-1-1, so that the upper staggered layer panel 8-1 can be directly hung on the positioning protrusion 1-1 of the above-mentioned ceiling panel 1, while ensuring the fit between the above-mentioned upper staggered layer panel 8-1 and the ceiling panel 1, so as to realize the rapid disassembly and assembly between the upper staggered layer panel 8-1 and the ceiling panel 1 while ensuring the stability of the structure at the connection between the upper staggered layer panel 8-1 and the ceiling panel 1.

[0044] The light strip structure in the present embodiment is mainly composed of a lamp housing 5, a lamp shade 6 and lamp beads 7.

There is an interference fit between the top of the lower staggered layer board 8-2 and this clamping groove. While realizing the installation of the lamp strip structure by clamping the top of the lower staggered layer board 8-2 into this clamping groove, the quick connection between the upper staggered layer board 8-1 and the lower staggered layer board 8-2 is realized, further shortening the installation working hours of the lamp strip structure. The cross - section of the clamping groove here is rectangular. Correspondingly, the cross - section at the top of the lower staggered layer board 8-2 is also rectangular.
