An outdoor-type signboard using a chip LED module is provided to protect a printed circuit board and a chip LED from ultra-violet rays and moisture by combining the printed circuit board and the chip LED with a protective film. An outdoor-type signboard using a chip LED module comprises a printed circuit board, a protective film(300), a grill(400), and a radiant heat plate. The printed circuit board has a plurality of chip LEDs which are arranged with a grid form and attached on the printed circuit board. The protective film for protecting ultra-violet rays has a plurality of caps(310) corresponding to the position of the plurality of the chip LEDs and is combined with a front side of the printed circuit board. The grill combined with a front side of the protective film has a plurality of grooves(420) for fixing the caps, and a light shielding unit(410) is installed in an upper part of each groove. The radiant heat plate is attached on a rear side of the printed circuit board for radiating heat generated from the printed circuit board.
