PURPOSE: A signboard LED lamp and a coupling structure between the printed circuit boards, are provided to prepare a connecting pin penetrating through the printed circuit board and a case, thereby smooth the current. CONSTITUTION: A connecting pin is connected to a circuit pattern of a printed circuit board. A case(30) has a cover covering a lower part. The case settles the printed circuit board. An epoxy molding unit(40) passes the current between the connecting pin and a conduit. The epoxy molding unit is formed at an upper surface of the printed circuit board and a lower side of the case. |
