A lighting control device is provided to maximize the illuminating effect and reduce a cost by diffusing or focusing illumination range of light. A lighting control device comprises a fixture(15), a moving body(10) and a lens(20). The fixture is fixed to a case(51) of an electric lamp(50). A hollow is formed inside the fixture. A mounting unit is formed in the lower inside diameter side of the fixture. The mounting unit is combined in the case of the electric lamp with a screwing mode or a joining mode. The moving body moves to the fixture with a screw or sliding. Therefore, the moving body moves relatively to a light source(52) of the electric lamp. The both end parts of the moving body are opened. The hollow is formed inside the moving body. The light source of the electric lamp is a light emitting diode bulb. A connector is interposed between the case of the electric lamp and the fixture. The lens is combined in the other end opening of the moving body with a fixing ring. |
