FIG. 2 is a view showing the arrangement of the main light source unit and the spare light source unit.

1 to 4, the LED lighting apparatus according to an embodiment of the present invention includes a light source 10, a substrate 20, a heat dissipation unit 30, and an optical lens unit 40.

In the light source unit 10, a plurality of LED chips are arranged in a predetermined arrangement pattern, and the arrangement pattern is how the several LED chips are arranged in the light source unit 10, and is not limited thereto .

Accordingly, it is intended to clearly show that various arrangements other than those shown in the drawings are possible.

The light source part 10 has a main light source part 11 arranged in a predetermined arrangement pattern on the substrate 20 and a light source part 11 having the same arrangement pattern as the main light source part 11, And a preliminary light source unit 12 which is rotated by an angle and is disposed on the substrate 20.
