The LED 121 is disposed outside the support 220 to prevent the light emitted from the LED 121 from being blocked by the support 220 before being reflected by the reflector 300.

The other end of the support part 220 is inserted into the coupling hole 312 to be described later, and then rotates in one direction so as to be in contact with the upper surface of the locking plate 311 and coupled to the reflecting plate 300.

And, as shown in Figure 4, the other end of the support 220, the engaging projection 221 is formed protruding.

When the other end of the support protrusion 220 is inserted into the coupling hole 312 and rotates in one direction, the locking protrusion 221 is inserted into the locking groove 314 which will be described later to be inserted into the coupling hole 312 ( The other end of the 220 may be fixed to the reflecting plate 300 to prevent the other end of the support 220 from being arbitrarily rotated in another direction to be separated from the reflecting plate 300.

The coupling member 200 as described above is composed of three are arranged at the same interval with respect to the heat dissipation unit 110.

By forming the 315, it is easy to rotate the other end of the support 220 to be disposed between the upper surface of the locking plate 311 and the lower surface of the locking portion 313.

When the other end of the support part 220 rotates in one direction by minimizing the separation interval between the locking groove 314 and the insertion groove 315, the locking protrusion 221 leaves the insertion groove 315 to allow the locking groove 315. 314 is easily inserted.

As such, when the other end of the support part 220 is rotated in one direction while being inserted into the coupling hole 312, the locking protrusion 221 is separated from the insertion groove 315 and inserted into the locking groove 314. The other end of the support part 220 is fixedly coupled to the fastening part 310.

In some cases, the locking groove 314 and the insertion groove 315 may be formed on the upper surface of the support part 220, and the locking protrusion 221 may be formed on the lower surface of the locking part 313.
