    Abstract: A lighting device with color temperature gradation is disclosed. The lighting device has a first white light emitting diode (LED) source with a first color temperature and a second white LED source with a second color temperature. The lighting device further comprises a controller adapted to generate a pulse width modulation (PWM) signal and to supply the first white LED with a first portion of the PWM signal and the second white LED with a second portion of the PWM signal in order to obtain a collective output of the lighting device with an output color temperature in between of a first color temperature and the second color temperature. The method of gradating the color temperature of a lighting device is also disclosed.
