Abstract In this paper, the effect of color temperature on color coordinate difference between rare earth three origin color phosphors and lamps are investigated. The optimum range color coordinates of various color temperature phosphors are suggested by the change law of Δx, Δy follow by color temperature variation as well as color coordinate range of various fluorescent lamps.
