7, when a hexagonal front case module 10c is introduced, the side case module 30 of the present invention can be used to manufacture the LED module 10 without the necessity of separately preparing a separate side case. Since the case of the lighting can be manufactured, the manufacturer can produce various kinds of LED lighting cases at low cost and use the molds of the same standard.

Further, even though a circular front case module is not shown in the drawing, if a round front case module having a different diameter is required, the side case module on the arcuate side can be manufactured as one mold and the side case module of the same standard can be assembled and manufactured Therefore, the cost reduction effect is very large, which is very advantageous in terms of price competitiveness, and thus has excellent versatility and utility.

The connection member 50 is a plate-shaped member having a predetermined width, and is provided with a pair of connection grooves 51 at both side ends in the longitudinal direction. The pair of coupling grooves 51 are provided at the front and rear opposite positions as in the pair of coupling grooves 31 provided in the side case module 30, So that both the module 30 and the connecting member 50 are fastened together.

Hereinafter, for convenience of explanation, the connection groove 51 provided at the front side of one side will be referred to as a first connection groove 51A and the connection groove 51 provided at the rear side of the other side will be referred to as a second connection groove 51B .

An example of the use of the LED illumination case using the connecting member 50 of the present invention will be described in detail. As shown in FIG. 6, the separate illumination cases 1 and 2, which are used as one LED illumination case, If necessary, the side case module 30 at the position to be interviewed in the LED lighting case 1 at one side of the two blocked LED lighting cases is first separated.

That is, when the side case module 30 to be interviewed is separated from the fastening rods 20, and the connecting member 50 is coupled to the remaining space of the remaining fastening rods 20, , The user can use LED lights having various sizes and shapes only by purchasing only the inexpensive connecting member 50. Therefore, when a plurality of LED lighting cases are assembled using a connecting member as well as the example shown in FIG. 6, various types of LED lighting cases as shown in FIG. 7 can be arbitrarily assembled by the user and used.

As described above, when the LED lighting case having different sizes is required, the front side case module 10 can be used separately by using only the front side case module 30. However, It is necessary to produce a separate mold for manufacturing the injection mold. Therefore, in consideration of the cost of manufacturing the mold, which occupies the largest portion of the cost except for the labor cost in the injection molding, LED lighting cases can be modified and assembled in various ways, which is very advantageous in terms of cost to both the manufacturer and the user.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications, And substitutions are to be construed as falling within the scope of protection of the present invention.
