Patent ID: 8235575

Claim:
A light emitting diode (LED) light board comprising: a light guide panel (LGP) shaped as a rectangle for inducing a path and scattering of light; an LED module disposed at a lateral side of the LGP and comprising a plurality of LEDs for irradiating light; a first frame having the LED module embedded therein and coupled to one side of an edge of the LGP; a second frame coupled to the other side of the edge of the LGP perpendicular to both ends of the first frame; and a corner finishing end on which the first frame and the second frame are connected to each other and corners of the first frame and the second frame are finished, wherein the first frame comprises a first sidewall formed at one side of an edge of the LGP, a first upper wing bent on an end of the first sidewall, and a first lower wing bent on the other end of the first sidewall, having a larger width than that of the first upper wing and attached to one bottom surface of the edge of the LGP, and the second frame comprises a second sidewall formed at the other side of an edge of the LGP, a second upper wing bent on an end of the second sidewall, and a second lower wing bent on the other end of the second sidewall, having a larger width than that of the second upper wing and attached to the other bottom surface of the edge of the LGP, and both ends of each of the first frame and the second frame are cut to be perpendicular to each other, and in order to assemble the first and second frames in the form of a rectangular frame, when an end of a pair of second lower wings is disposed close to a side of a pair of first lower wings, a gap space is formed between the first upper wing and the second upper wing, and the corner finishing end comprises a first insertion end inserted between the first sidewall and the first upper and lower wings, a second insertion end inserted between the second sidewall and the second upper and lower wings, and a gap space finishing portion that closes the gap space between the first upper wing and the second upper wing when the first and second insertion ends are inserted into the first and second frames, respectively, and simultaneously forms the same surface as the surface of the first and second upper wings.
