<p>The present invention relates to a brightness adjusting system for an illumination panel of an aircraft operation console, the system comprising: a controller for controlling voltage; a power IC for outputting power; a digital potentiometer for changing the output value of the power IC; an operation switch for adjusting the brightness of the illumination panel of the operation console including an instrument and a console; and an LCD display device discernible by the naked eye of a user, wherein the controller comprises: a program for calculating a selected input value of the operation console of the user; a memory for storing a changed tuning value; and an output part for transmitting data to the digital potentiometer, wherein the power IC receives the control value of the digital potentiometer and outputs a preset DC voltage to each illumination panel, and wherein the digital potentiometer delivers a signal requested by the controller to an output voltage control port of the power IC. Accordingly, the present invention has a remarkable effect in efficiently using the brightness of each illumination panel.</p> |
