Since the hole H1 is formed at the boundary between the center surface 14A and the side surface 14B of the frame 14, the side surface 14B of the frame 14 may be easily bent. In addition, the circuit driver 20 of the LED element 12 provided on the front of the frame 14 and the LED element 12 hidden behind the frame 14 by the hole H1 formed in the frame 14. ) Can be guided, so that the LED element 12 and the circuit driver 20 can be easily connected, and the circuit line 22 is neatly processed so that the aesthetic side 14B desirable.

Of course, a hole H2 may be formed in the frame 14 at a portion other than the boundary between the center surface 14A and the side surface 14B of the frame 14 to guide the circuit line.

The frame 14 may be formed to be convex toward the LED element 12, but more preferably, is formed in a convex shape toward the LED element 12. That is, since the LED element 12 is not surrounded by the frame 14 and the frame 14 is open, the light of the LED element 12 can be more diffused and heat This is advantageous in the heat dissipating side 14B of the LED element 12 that is generated a lot.

As described above, the frame 14 is an element that generates a lot of heat, and is formed of a heat conductive material such as a metal material such as aluminum or iron to improve durability of the LED module 10. More preferably.

The frame 14 configured as described above may be formed of the frame 14 having the center surface 14A and the side surface 14B of the frame 14 bent from the beginning, but more preferably manufactured as follows. desirable. That is, first, as shown in FIG. 4, the frame 14 is formed to correspond to the unfolded shape of the frame 14. Then, as shown in FIG. 5, the center surface 14A of the frame 14 is formed. The side 14B of the frame 14 can be bent to form the final shape of the frame 14. Therefore, it is possible to form a metal material such as aluminum or iron, which has good heat dissipation and is advantageous in terms of cost and 14B. In addition, it is possible to adjust and change the bending angle of the frame 14 indicated by 'θ' in the figure, thereby easily combining the frame 14 and the body 30 to be described later.

The LED module 10 may further include a substrate 16 installed at the front of the frame 14 to mount the LED element 12 thereon. The substrate 16 may be integrally formed, but it is more preferable that the substrate 16 is divided into a plurality of parts so that the structural design is easy and partial repair and maintenance are possible. The substrate 16 may be coupled to the frame 14 by a fastening member such as a screw.

Meanwhile, the LED lighting apparatus according to the present invention further includes a body 30 supporting the LED module 10 so that the LED module 10 configured as described above can be modularized and installed more easily in an indoor or outdoor environment. It can be configured to include.

The body 30 may be configured such that a space may be formed between the frame 14 and the frame 14. Therefore, the circuit driver 20 can be mounted in a hidden state in the space between the body 30 and the frame 14, which is preferable in terms of aesthetics and safety management 14B.

As described above, the body 30 may be formed of a thermally conductive material like the frame 14 to dissipate the LED module 10.
