The LED luminaire 100 shown in FIG. 1 and FIG. 2 is described as an example of a luminaire having a quadrangular structure, and its configuration may be made with a polygonal structure of more than a triangle. An example of a pentagonal structure is illustrated in FIG. 6 below as an example.

Accordingly, in the luminaire having a quadrangular structure, four main frames 110 and four brackets 120 are assembled as shown in FIGS. 1 and 2.

The four main frames 110 are identical in structure to each other, but in the case in which the quadrangular structure has a rectangular shape, only the length of the frame is different, and the internal and external structures are the same.

That is, since the internal and external structures of the four main frames 110 are the same, it is possible to cut the frame produced by one extrusion device to the required length and use it as the main frame 110.

The four main frames 110 form the side body of the LED luminaire, and the four brackets 120 are located at the corner portions where the four main frames 110 abut to facilitate the coupling between the main frames 110.

The diffuser plate 130 is a plate for brightening light by diffusing the LED light source to the outside, the PCB substrate 140 is a plate on which a plurality of LED modules are mounted and a circuit is printed, and the cover 150 is an LED The cover plate covers the upper opening of the luminaire 100.

In addition, one or more locking holes 307 may be formed on one surface of the body 301.

The fastening groove 302 is inserted into the fastening protrusion 402 of the bracket 120 shown in Figure 4 to assist the coupling of the main frame and the adjacent main frame. In particular, when the fastening protrusion 402 is inserted into the fastening groove 302, the locking protrusion 404 is formed in the fastening protrusion 402 so that the locking protrusion 404 is inserted into the locking hole 307 of the main frame 110. By doing so, the main frame 110 and the bracket 120 can be used as a locking device so as not to fall easily when coupled.

In particular, since the locking protrusion 404 is inclined at a predetermined angle, the locking protrusion 404 and the locking hole 307 may be self locking.

The slide grooves 303, 304, and 305 may be divided into three parts and extended by the length of the body 301. The slide grooves 303 are slides for slidingly inserting the diffusion plate 130.

When the power is activated, the LED module emits a light source and the light source is externally spread through the diffusion plate 130. Is investigated. In this case, since the diffusion plate 130 is viewed from the outside, there is a problem that the LED module inside is visible by the light source. Therefore, this is solved by changing the mounting height of the PCB substrate 140. However, varying the mounting height of the PCB substrate 140 causes a problem in that the size of the LED lighting fixtures must be manufactured in various forms. Such a portion of the present invention can be solved by configuring the slide groove 304 in multiple stages.

The main wing 306 is a plate that projects straight outward from the lower end of the body 301. This eliminates the empty space that may occur due to the fastening of the bracket 120 at the corners when the main frames 110 are coupled to each other, and forms a complete square frame structure when assembled with the auxiliary wing 403 of the bracket 120. It is a configuration to add design elements.

Referring to FIG. 4, the bracket 120 includes a body 401, fastening protrusions 402a to 402d, and an auxiliary wing 403.
