PURPOSE: A prefabricated board-shape lighting device is provided to improve the visual effect by using a transparency pad which has a laser processing groove according to a printed pattern on a real image printing sheet. CONSTITUTION: A frame part(110) comprises a plurality of first frames(120a,120b) and a plurality of second frames(130b). The light source arrangement space is formed in the upper side of the frame part. LED elements are built in a longitudinal direction of the light source arrangement space. The first frames are each other faced. The second frames is connected to through a fixing part in both sides of the first frames. A lighting part(170) has a board shaped laminated structure shape arranged in the upper side of the frame part. The lighting part releases light irradiated from LED elements built in the first frames the front side. The lighting part comprises a transparency pad with a real image printing sheet and a laser processing groove. |
