The kerb (100) has a photovoltaic generator (111) connected to a battery (113), a control electronics (114), high-yield LED lamps (115, 116) and a directional lens so as to return essence of light emitted by the lamp in a tangent direction to the kerb of a road pavement, where the kerb includes an autonomous directional lighting device. A recovering unit is used for recovering a part of impact energy generated by a support of a heavy mobile in displacement on part of a surface of the kerb. A cavity (112) and a point assembly are arranged on a side face (120) of the kerb. The kerb is made of concrete material, marble and granite. |
