Abstract: A lighting device which causes a first light source to emit illumination light and a second light source to emit illumination light having a color temperature higher than a color temperature of the illumination light emitted by the first light source includes: an illuminator which includes a first switching element connected in series to the first light source, and a second switching element connected in series to the second light source; an illumination controller which controls the illuminator to place at least one of the first switching element and the second switching element into an off state; and a constant-current controller which detects a sum of values of currents flowing through the first light source and the second light source, and controls the first switching element and the second switching element based on the sum.

Abstract: A lighting device includes a power conversion unit, an impedance adjustment unit, a first control unit, and a second control unit. The power conversion unit is configured to convert input power to direct-current power used for a light source. The impedance adjustment unit is formed of a series circuit of a resistor element and a switch element and is coupled to the light source in parallel, relative to the power conversion unit. The second control unit is configured to cause the power conversion unit to operate, for each burst cycle, for an operation period which is not longer than the burst cycle, and increase and reduce the ratio of the operation period to the burst cycle. The first control unit is configured to make the switch element conductive for a predetermined adjustment period which is not longer than the operation period, during the operation period.
