An orientation change device serves for a lamp frame and light projection direction. An upper cap serves for guiding power. A lower end thereof is installed with an electric stud. Two ends of a connecting seat have insulated plugs. A conductive post is positioned in each of the plug at a position corresponding the electric stud. A plurality of lamp seat are fixed to a periphery of the connecting seat by a frame. An inner surface of the conductive post is conductive to a wire of one of a plurality of lamp seat. A plurality of wires are electrically connected to the conductive post. Then the plugs containing the conductive posts are installed at two ends of the connecting seat. Thereby, any one end of the connecting seat is connected to the upper cap. Thus, the conductive posts are connective to the electric stud.
