Zusammenfassung:A color temperature control method using multi color light emitting diode and a medium recording program thereof are provided to implement color temperature change which accurately coincides with a black body locus by controlling voltage and current in composing a light emitting diode control circuit. A color temperature control method using multi color light emitting diode comprises: a step(S100) determining the number of light emitting diodes to achieve target color temperature based on optical color mixing theory; a step(S120) calculating theoretical value for target color temperature achievement; a step(S140) setting up measured value by experimenting a light emitting diode module and a control circuit according to the number of determined light emitting diodes; and a step(S160) achieving the target color temperature according to the correction factor.
