PURPOSE: A built-in lighting device is provided to remotely control each illumination installed on the ceiling. CONSTITUTION: A plate mount(30) is combined with a moving nut(200-1) of two ball screws(20) to vertically lift the plate mount. A drive shaft pulley(220) is combined with the upper end of the plate mount. A rotary shaft of a lifting motor(230) is connected to the drive shaft pulley. The lifting motor is installed on lower end of the plate mount to save an inner space of a cover(10). Two driven shaft pulleys(210) and the drive shaft pulley and a chain or belt(240) form a triangle shape.
