The present invention relates to a lighting device for a speed bump to be automatically cleaned, comprising: a cylindrical body installed in a speed bump and having a cylinder function; an elevation body inserted into the body to be elevated; a light emission part arranged on the top of the elevation body and having multiple LED bulbs and a cylindrical tempered glass cover; and an upper body to lower the elevation body with the compression of vehicle wheels. The lighting device for a speed bump to be automatically cleaned makes drivers recognize the speed bump from a distance with the illumination of the light emission part arranged on the elevation body elevated by the pressure of gas charged in the body or the elastic force of a spring and also automatically cleans the cylindrical tempered glass cover of the light emission part to allow light to be transmitted at all times by rubbing the tempered glass cover with a sealing arranged on the body while the elevation body is retracted into the body by the upper body pressed by the vehicle wheels whenever vehicles pass the speed bump. |
