<P>PROBLEM TO BE SOLVED: To provide a light emitting device and a lighting apparatus using the same with which color reproducibility of mixed color light based on a group of plural solid light emitting elements can be enhanced. <P>SOLUTION: A lighting controller 2r comprises a driving circuit 21r for supplying current Ir to a solid light emitting element group Lr, a peak current detector 25r for detecting the peak value Ipr of the current Ir and a control circuit 22r for feedback-controlling the driving circuit 21r so that the peak value Ipr is coincident with a reference voltage Vref. The lighting controllers 2g, 2b comprise driving circuits 21g, 21b for supplying current Ig, Ib to solid light emitting element groups Lg, Lb, peak current detectors 25g, 25b for detecting the peak values Ipg, Ipb of the current Ig, Ib, and control circuits 22g, 22b for performing feedback control on the driving circuits 21g, 21b so that the reference voltages VrefG, VrefB based on the peak value Ipr are coincident with the peak values Ipg, Ipb. <P>COPYRIGHT: (C)2013,JPO&INPIT |
