Lighting device with color temperature control function

A lighting device with color temperature control function, comprising:

• two modulated power input ends, receiving a modulated power via a power modulation module, wherein the modulated power is composed of multiple cycles of a sinewave, and each cycle of the sinewave has a firing angle;
• a rectifier, electrically connected to the modulated power input ends to receive and rectify the modulated power, and having a rectifier output end to output a rectified modulated power;
• a first LED module, electrically connected to the rectifier output end to receive the rectified modulated power;
• a second LED module, electrically connected to the rectifier output end to receive the rectified modulated power;
• wherein a color temperature of the first LED module is different to a color temperature of the second LED module;
• a dimming control unit, electrically connected to the first LED module and the second LED module, and having a power signal input end, wherein the power signal input end is electrically connected to the rectifier output end to receive the rectified modulated power;
• wherein the dimming control unit reads a lighting modulation command code, via a wireless receiver module and a firing angle control unit, that is carried in the modulated power according to the firing angle of each cycle of the sinewave, and respectively controls luminous intensity of the first LED module and the second LED module, such that the first LED module and the second LED module perform lighting with a specific combination of color temperatures.
