Abstract
Disclosed is a lighting control method and a lighting control device for a light source having LEDs, and a lighting device and includes acquiring the number of LEDs and a control curve for controlling changes in brightness and color of the light emitted from each LED over time, the control curve defines the same brightness cycle and color cycle for each LED, the brightness cycle indicates a brightness period and a brightness curve of the change in brightness over time within each period, determining a time offset on the control curve according to the number of LEDs and the brightness change period, determining the starting timings of the remaining LEDs on the control curve according to the starting timing of the first LED and the time offset, and controlling each LED from the starting timing on the control curve, to emit light according to the brightness and color determined.
