The present invention relates to a side light-type LED lighting panel. The LED lighting panel comprises: a light guide plate; a diffusion sheet disposed at the upper surface of the light guide plate; a reflection sheet disposed at the lower surface of the light guide plate; a first LED substrate on which a plurality of LEDs are mounted, and which is disposed at the side surface of the light guide plate to enable incidence of light emitted by the LEDs through the side surface of the light guide plate, and which is arranged to contact the edge of the upper surface of the light guide plate, and which fixes the diffusion sheet along the edge of the upper surface of the light guide plate; a second LED substrate on which a plurality of LEDs are mounted, and which is disposed at the side surface of the light guide plate to enable incidence of light emitted by the LEDs through the side surface of the light guide plate, and which is arranged to contact the edge of the lower surface of the light guide plate, and which fixes the reflection sheet along the edge of the lower surface of the light guide plate; and a metal spacer which is interposed between the first and second LED substrates, and which couples the outer surfaces of the first LED substrate and the second LED substrate together. Accordingly, the present invention increases light incident through the side surface of the light guide plate to provide light with an excellent luminance, and improves a fixing member for fixing LEDs onto the light guide plate to achieve improved heat-dissipating performance. |
