1 to 3, a safety case 240 is formed at one side of the support frame 200 and is configured to be coupled to cover the outer side of the connection unit 400. As shown in FIG.

1 and 2, the safety case 240 is coupled to the support frame 200 so as to surround the outside of the connection unit 400. The safety case 240 is lightweight and has strength so as not to be easily damaged by an external impact High metal or plastic material.

In the present invention, when the connection unit 400, the fixing plate 230, and the safety case 240 are coupled to one side of the support frame 200, although the connection unit is not illustrated, The fixing frame 230 and the safety case 240 may be coupled to one side of the support frame 200 and the connection portion 400 by applying various fastening means such as nuts and bolts according to the user's selection, The fixing plate 230 and the safety case 240 can be combined.

As described above, according to the present invention, even when heat is generated in the LED module, it is possible to smoothly adjust the heat of the LED module through the structure of the heat sink, achieve stable use of the LED lighting device, The user can smoothly change the direction of the light generated by the LED module, and the LED module can be efficiently used.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit or scope of the invention as set forth in the following claims It will be apparent to those of ordinary skill in the art.
