<p>The present invention relates to an LED lighting controlling method capable of changing output brightness of mixed lighting, which includes: (a) a step in which an output brightness change control part judges whether a power off signal is delivered within a fixed time or not, in case that a power on signal for turning on an LED is delivered; (b) a step in which the output brightness change control part recognizes the delivered power off signal as 'output brightness change signal' for a warm type and a white type LED, in case that the power off signal is delivered within the fixed time according to the judgment result of the (a) step; (c) a step in which the output brightness change control part checks output brightness of each of the warm type and the white type LED which are set up according to the 'output brightness change signal' recognized through the (b) step; (d) a step in which the output brightness change control part generates a 'change control signal' to next output brightness from output brightness established for each of the warm type and the white type LED, and transmits the generated 'change control signal' to an LED control part; and (e) a step in which the LED control part controls to output by changing to the next output brightness from the output brightness established for each of the warm type and the white type LED currently, in case that a next power on signal is delivered, on the basis of the 'change control signal'.
