<p>PROBLEM TO BE SOLVED: To provide an illumination device comprising a DC light emitting load capable of lighting control and color matching which are delicate and have high degree of freedom.SOLUTION: An illumination device 100 comprising a DC light emitting load comprises: at least first and second connection points T1 and T2; a DC light emitting load 2 which is connected between the at least first and second connection points T1 and T2 and is composed of first and second DC light emitting devices LED1 and LED2; and a drive device 1 for outputting AC power in a pulse shape from the at least first and second connection points T1 and T2 to the DC light emitting load 2. The first and second DC light emitting devices LED1 and LED2 are configured so as to have color temperatures differing from each other and emit light alternately according to the AC power. The drive device 1 controls the AC power on the basis of a lighting control command input from the outside of the drive device 1, to change brightness and color of the light output from the DC light emitting load 2.</p> |
