The LED lamp having the above structure includes an upper frame 100 and a lower frame 200 coupled to each other and an upper frame 100 coupled to the lower frame 200. An LED module 300 is inclined inside the lower frame 200, And a diffusion member 400 for diffusing light toward the center while protecting the LED module 300.

Accordingly, when light is generated in the LED module 300 by receiving power from the power PCB 500 provided in the receiving portion 110 of the upper frame 100, such light is diffused through the diffusion member 400, 100 through the hollow portion 210 of the lower frame 200 and downwardly irradiated through the hollow portion 210 of the lower frame 200 to further enhance the efficiency of illumination.

Although the present invention has been fully described by way of example with reference to the accompanying drawings, it is to be noted that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the scope of the disclosed contents should not be limited to the described embodiments, but should be determined by the appended claims and equivalents thereof.
