A lighting apparatus comprises a plurality of light sources, a power conversion circuit, a plurality of load-driving coils and a feedback generation coil. The power conversion circuit generates a driving signal for the load-driving coils to generate substantially identical driving currents for driving every light source. Furthermore, the feedback generation coil generates a feedback signal based on the inductions of the currents flowing though the plurality of load driving coils.
