<p>PURPOSE: An automatic power saving system which is centrally controlled with a programmed switch is provided to maintain same brightness by controlling the brightness of a lighting apparatus with reference to natural lighting and other incident illumination. CONSTITUTION: An automatic power saving system which is centrally controlled comprises a lighting apparatus(10), a control controller(20), a brightness and illuminance sensor(31), a programmed switch(30), and a central control server(40). The automatic power saving system further includes a movement and infrared ray sensor(32). The lighting apparatus controls brightness according to the size of driving power which is inputted. The control controller controls the brightness of the lighting apparatus. The brightness and illuminance sensor continuously outputs a measured value, which senses neighboring brightness/illuminance, in an analog signal.</p> |
