PURPOSE: A building wall direction system is provided to offer various designs and sounds appropriate for the designs on a building wall efficiently even at night and in four seasons. CONSTITUTION: A building wall direction system includes an individual expression unit(10) which has an individual expressing light emitting line which is equipped with an optical fiber in which one end is exposed to the outside, is installed on a building wall, and directs an individual design which is not overlapped with other total directed designs and an individual expression light source part which radiates light to the optical fiber of the individual expression light emitting line; an overlapping expression unit(20) which has an overlapping expression light emitting line which is equipped with an optical fiber in which one end is exposed to the outside, is installed in the building wall, and directs an overlapping design among total directed designs and an overlapping expression light source part which radiates light to the optical fiber of the overlapping expression light emitting line; a control unit(30) which directs various designs on the wall by controlling the overlapping expression light source part of the overlapping expression unit and the individual expression light source part of the individual expression unit according to an input signal if a signal about a design for a direction is inputted and making the optical fiber of the individual expression light emitting line and the overlapping expression light emitting line emit light; and an input unit(40) which inputs the input signal to the control unit. |
