The lighting device of the present invention includes a reflective member layer, an optical resin layer formed on the reflective member layer, and a transparent electrode film layer formed on the optical resin layer, wherein a plurality of light emitting units are formed on a lower surface of the transparent electrode film layer. As a result, it is possible to block the root cause of hot spots and efficiently implement the function as a surface light source, thereby providing excellent light efficiency, and reducing the type of raw material and the number of manufacturing processes through the exclusion of the PCB printed circuit board and the selective application of the second reflection pattern. It works. |
