Abstract

The present invention relates to a laser irradiation apparatus that allows a plurality of laser beams to illuminate a lane on a road or an exterior wall of a building so as to create a predetermined pattern or guide sign by easily and finely adjusting points that will be irradiated by the laser beams such as exterior walls of a building. The laser irradiation apparatus includes a light-emitting unit irradiating light onto a road surface or an exterior wall of a building so as to indicate a pattern or figure, a power supply unit supplying power to the light-emitting unit, and a support unit supporting the light-emitting unit so as to easily adjust the direction of the light irradiated by the light-emitting unit. The laser irradiation apparatus can finely adjust the irradiation point of laser with directionality and can fix the position of the set laser irradiation point, thereby allowing easy indication of a road lane or a specific pattern on an exterior wall of a building.
