The present invention relates to a road boundary stone distinguishing a roadway and a sidewalk. An indirect illumination type road boundary stone includes: a body unit; a slope unit which is formed on a side of the body and is cut from a side surface to the inner side to be tilted and form a downward surface; a lighting unit which is installed on a side of the upper side surface or the slope unit of the body unit; and a solar cell panel which is installed on a side of the body unit to supply power to the lighting unit. The indirect illumination type road boundary stone according to the present invention uses replaceable LED lamps formed to have the installation surface to be toward an exposed surface to prevent from being directly exposed the light source to a driver′s field of view and interfering the sight. Also, the present invention uses the solar cell or a piezoelectric panel to generate power on its own to light the lamp and be used even in an area such as a tunnel which makes the solar power generation difficult. |
