On the other hand, in order to cover the mounting member 125 is coupled from the lower side to the upper side of the coupling groove 115 to mount the side frame assembly 119 to the ceiling (C), each of the protective frame ( 190).

The protective frame 190 is rotatably installed on the side frame 110. Before describing the structure of the protective frame 190, the structure of the side frame 110 for installing the protective frame 190 to be rotatable will be briefly described.

The side frame 110 has the above-described components, as well as the rod-shaped hinge ribs 118 formed in the longitudinal direction on the lower side of the edge surface and formed in the diagonal direction of the upper side of the hinge ribs 118 to form an arc. It has a first spring groove 117 is supported either one of the lower end portion (127b) or the upper end portion (127a) of the spring (127). In this embodiment, the upper end 127a of the spring 127 is described as being fitted in the first spring groove 117. At this time, the spring 127 is preferably a wire spring having an arc shape.

The protective frame 190 is formed on the hinge coupling groove 198 into which the hinge rib 118 is fitted and the upper side of the hinge coupling groove 198 to support the lower end 127b of the spring 127. A shaft portion 194 having a spring groove 197 is formed, and a protection portion 191 formed to extend to cover the lower portion of the side frame 110.

The protective frame 190 as described above is rotated based on the hinge rib 118 by the hinge rib 118 is fitted into the hinge coupling groove 198. That is, the protection frame 190 is rotated to open and close the lower part of the side frame 110 from the outside. Therefore, when the protection frame 190 is rotated in a direction away from the side frame 110, that is, the opening direction, the lower portion of the side frame 110 is exposed from the outside (see FIG. 8).

On the other hand, the spring 127 provides an elastic force to maintain the protection frame 190 is opened or closed from the side frame 110. That is, the spring 127 is formed between the first spring groove 117 and the second spring groove 197 when the protection frame 190 is rotated in the direction in which the lower portion of the side frame 110 is opened or closed. The elastic force is provided as the distance varies. For example, when the lower portion of the side frame 110 is opened or closed by the protection frame 190, the distance between the first spring groove 117 and the second spring groove 197 is maintained far. When the second spring groove 197 moves in the rotation direction, the distance between the first spring groove 117 and the second spring groove 197 gradually decreases. That is, the distance between the first and second spring grooves gradually decreases to the middle of the angle at which the protection frame 190 is rotated, and gradually goes away again after the middle. Therefore, when the protection frame 190 is rotated in the direction of opening the lower side of the side frame 110, the distance between the spring 127, the first spring groove 117 and the second spring groove 197 is far Since the elastic force is applied so that the protective frame 190 is rotated about halfway, the elastic energy completely rotates the protective frame 190.

Each corner of the LED lamp 100 having the above-described structure is formed to be pointed, causing a problem that the user is injured when the user hits. In order to solve this problem, the corner coupling member 150 is formed with a curved portion 151 at each corner.

Cutting edges 110a are formed at each corner so that the edge coupling member 150 is installed on the LED lamp 100. The cut surface 110a is formed to be perpendicular to each corner of the side frame assembly 119. At this time, each corner of the protective frame 190 installed in the side frame 110 also has a cut surface corresponding to the cut surface (110a). Thus, the curved portion 151 of the corner coupling member 150 is located in the corner is coupled in close contact with the incision surface (110a).

More specifically, the corner coupling member 150 is perpendicular to the fan-shaped body 152 having a rounded curved portion 151 and a contact surface 153 formed to correspond to the cut surface 110a. The fitting protrusions 154 formed on the contact surfaces 153 are provided.

The fitting protrusion 154 is formed at a position corresponding to the fitting groove 110b formed in the side frame 110 and inserted into the fitting groove 110b. Accordingly, when the fitting protrusion 154 is inserted into and installed in contact with the cutting surface 110a of the side frame assembly 119, the curved portions 151 are positioned at each corner of the side frame assembly 119. This prevents safety accidents caused by sharp edges.

On the other hand, the LED lamp 100 as described above as an example, has been shown and described as having a quadrilateral shape, but is not limited to this, may be assembled and formed to have a variety of forms.

For example, as illustrated in FIG. 10, the LED lamp 200 may be configured such that three side frames 210 are sequentially assembled to have a triangular shape, or as illustrated in FIG. The side frames 310 may be sequentially assembled to form a hexagonal LED lamp 300 having a hexagonal shape. In addition, the LED lighting may be made to have a variety of forms, such as pentagonal shape, octagonal shape depending on the number of side frames. That is, the LED lamps 100, 200 and 300, the first corner brackets, cover frames, the first number having the same number as the number of side frames 110, 210, 310 forming the shape By providing the two corner brackets and the protective frames, it is possible to implement the LED lamps 100, 200, 300 to have a variety of shapes. In this case, the first corner bracket and the second corner bracket having a '-' shape may be connected to the neighboring side frame and the cover frame, respectively, according to the shape of the lighting lamp to be achieved.
