A lighting device(100) includes a power socket(110), a plurality of LED packages(130), a plurality of light pipes(140), and a printed circuit board(120). The printed circuit board is detachably coupled in the power socket. A plurality of LED packages is mounted on the printed circuit board. A plurality of LED packages is connected to the power socket. Each LED package includes a plurality of LED chips. Each light pipe converts a light emitted in the LED package as a point light source into one among a line light source or a surface light source. A plurality of patterns is formed in an inner surface of each light pipe in order to diffusely reflect a light emitted in the LED package.
