The second body 130 is inserted into the first corner 112 of the first body 110 so that the second body 130 is inserted into the first space 112 of the second body 130, (134) are positioned. At this time, one end of the positioning fixture 116 of the first body 110 is inserted into the third insertion groove 137 of the first boss 136 of the second body 130. The first protrusion 118 of the first body 110 is inserted into the fourth insertion groove 139 of the second boss 138 of the second body 130.

In this case, the first contact piece 28 of the fixed frame 20 and the second contact piece 28 of the cover 30 are inserted into the second insertion groove 131 formed in the gap retaining wall 134 of the second body 130 By inserting the flap 32, a rotational moment is prevented from acting on a screw fixed to the first fixing piece 114 of the first body 110, thereby maintaining a stable fixing state.

After the second body 130 is assembled to the first body 110, a screw is inserted into the second insertion hole 132 of the second body 130, and the first body 110 Is fastened.

When the fixing bolt 42 of the fixing bracket 40 is inserted into the first insertion hole 118 of the first body 110 and the second body 130 assembled to the first body 110, The fixing bolt 42 is protruded by a predetermined length through the insertion hole formed in the third boss 138 and the fixing nut 150 is fastened to the fixing bolt 42, The assembling of the first body 120 and the second body 130, the fixing frame 20, the cover 30 and the fixing bracket 40 is completed.

Then, the finishing cap 140 is inserted into the first body 110. The locking protrusion 147 formed at the second corner 144 of the finishing cap 140 is engaged with the first locking protrusion 1122 formed at the first corner 112 of the first body 110, Assembly of the finishing cap 140 is completed. In this case, one end of the fixing frame 20 and the cover 30 are inserted into the space between the second corners 144 of the finishing cap 140, so that the second plane 142 of the finishing cap 140 The fixing force of the fixing frame 20 and the cover 30 is amplified to the body 10 as it is in close contact with the cover 30.

In this manner, the body part 10, the stationary frame 20, the cover 30, and the fixing bracket 40 can be separated from each other, thereby making it possible to save a logistics cost and to assemble easily It is easy to disassemble and assemble.

1 to 9, the present invention is not limited to a '+' shaped lighting device, but may be formed in a '-' shape as shown in FIG. Of course, the present invention is not limited thereto, and various shapes such as a pentagon, a hexagon, and an octagon may be implemented to create a purpose and a design of a lighting apparatus. That is, since the fixing frame and the cover are formed on the outer periphery of the body made up of the first and second bodies and the finishing cap, the number of the lighting mechanisms can be used without limitation.

The above description is only one embodiment for implementing the LED lighting device, and the present invention is not limited to the above embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
