Provided is a lighting device that converts an exiting light into a stereoscopic light having a sense of depth or a sense of volume, whereby light images having stereoscopic effects can be implemented using light emitted from a light-emitting device and simultaneously, a structure of a printed circuit board (PCB) located at a lower portion of a light passage portion is eliminated and a direct-type light-emitting device located at sides of the light passage portion and having high versatility is used such that flexibility of the light passage portion is attained and a degree of freedom of a design can be enhanced.
