    Abstract: A lighting device includes a rectifier, a constant current regulator and a charge-discharge circuit. The constant current regulator is electrically connected in series with first and second solid-state light-emitting element arrays between a pair of output terminals of the rectifier. The constant current regulator is configured to adjust a current flowing through the second solid-state light-emitting element array to a constant current. The charge-discharge circuit is electrically connected in series with the first solid-state light-emitting element array between the pair of output terminals of the rectifier. The charge-discharge circuit includes a charge storage element, and is configured so that a charge current flows to the charge storage element through the first solid-state light-emitting element array, and so that a discharge current flows from the charge storage element to the second solid-state light-emitting element array.

    Abstract: A light source circuit includes light-emitting diodes and a constant current circuit that controls current flowing through light-emitting diodes to a fixed level. A DC power supply circuit outputs a DC voltage having a voltage value capable of causing light-emitting diodes to emit light. A light modulation control unit includes: a MOSFET electrically connected between DC power supply circuit and light source circuit; and a control circuit configured to control MOSFET. Control circuit is configured to turn MOSFET on and off with a duty ratio corresponding to a light modulation level such that DC voltage that is outputted from DC power supply circuit is converted to a square wave voltage, and the square wave voltage is outputted to light source circuit. The square wave voltage has an amplitude equal to the voltage value of the DC voltage that is outputted from DC power supply circuit.

    Abstract: A lighting device includes a constant-current circuit, a smoothing capacitor, a bypass circuit, a detection unit, and a bypass control unit. The constant-current circuit supplies a constant current to a plurality of solid-state light-emitting elements connected in series. The smoothing capacitor is connected between output terminals of the constant-current circuit. The bypass circuit is connected in parallel to one or more of the plurality of solid-state light-emitting elements. The detection unit detects whether the one or more solid-state light-emitting elements are open-circuited. When the detection unit detects that at least one of the one or more solid-state light-emitting elements is open-circuited, the bypass control unit discharges the smoothing capacitor during a discharge period to then bypass the one or more solid-state light-emitting elements through the bypass circuit.
