As shown in Figure 2, the LED lighting panel 100 according to an embodiment of the present invention is a light guide plate 110, a diffusion sheet 120, a reflective sheet 130, the first LED substrate 140, the second The LED substrate 150 and the spacer 160 are formed. The LED lighting panel 100 according to the present exemplary embodiment has a quadrangular shape as an emission surface on which the upper surface of the light guide plate 110 emits light.

As shown in FIGS. 2 and 3, the light guide plate 110 has an upper side of the light guide plate 110 when light emitted from each of the LEDs 142 and 152 mounted on the first and second LED substrates 140 and 150 is incident through the side surface. Light is emitted through the cotton. Here, the light guide plate 110 is a light guide made of a transmissive resin such as an acrylic resin, a polycarbonate resin, and an amorphous polyolefin resin.

The reflective sheet 130 disposed on the lower surface of the light guide plate 110 reflects the light incident through the side surface and transmits the light to the outside through the upper surface. The reflective sheet 130 may be manufactured by forming a high reflectivity metal thin film such as aluminum or silver on a thin resin substrate. In addition, the reflective sheet 130 may use a reflective plate made by applying a white or milky white paint on a thin resin substrate, a white resin plate made of a resin incorporating a white pigment, a high reflectivity metal thin plate such as aluminum or silver. . Light emitted through the upper surface of the light guide plate 110 is diffused by the diffusion sheet 120.
