PURPOSE: A light emitting diode module is provided to reduce an error rate caused by a printed circuit board by forming a protrusion of a printed circuit board in a bushing. CONSTITUTION: A case(20) is comprised of the bottom and a plurality of sidewalls perpendicularly formed from the outer circumference. An electric circuit has a printed circuit board turning an LED therein. A first side wall(25) and a second side wall are upwardly opened. A plurality of curve grooves on the lower part of a first side wall and a second side wall(27) correspond to a plurality recess. The recess is combined with a bushing. A protrusion contacting the top of the printed circuit board is formed inside a case of the bushing. The second side wall faces with the first side wall.
