Disclosed is a color lamp driving apparatus for generating illumination light of various colors by using a plurality of Red (R), Green (R), and Blue (B) lamps together with each other, having a color controller for generating a color control signal, which indicates driving time rates of R, G, and B lamp arrays, according to color information of required illumination light, and a lamp driving module for outputting a driving signal for driving each of R, G, and B lamp arrays according to the color control signal output from the color controller. The driving signal is set to apply driving times for the R, G, and B lamp arrays based on one among a start time point, a middle time point, and an end time point of each corresponding period &Dgr;T within one light-emitting period T.
