THE CHANGEABLE WALL PAPER SYSTEM

摘要

A changeable wall paper system is provided to perform indirect illumination by implementing emission by actively corresponding to luminous intensity of the surrounding environment. An LED panel(20) is attached to the front surface of a base panel inside a frame(10) and a plurality of LED lamps are installed in an outer circumference of the LED panel. A sensor dog is attached to a lateral side of a wall paper film with a constant interval. A motor is connected to a second upper roller and generates the rotation force of forward and backward directions. A proximity sensor senses the position of the sensor dog installed at the lateral side of the wall paper with the constant intervals. An illuminance sensor senses the illuminance indoors. A controller(90) includes a receiving part and a remote controller and is installed inside a room. When a signal received from the illuminance sensor is below a predetermined value, the electricity is applied to an LED lamp(21). When the signal to move the wall paper film(40) is received from the remote controller, the wall paper is moved by applying the electricity to the motor(50). If the proximity position is confirmed by receiving the signal from the proximity sensor, the movement of the wall paper film is stopped. The controller applies the electricity to the LED lamp only if the lighting switch is on.
