PROBLEM TO BE SOLVED: To provide a lighting device which does not malfunction even when a capacitive element is connected thereto as a load.SOLUTION: A lighting device of an embodiment includes a light emitting module, a first lightning circuit, and a backflow prevention circuit. The light emitting module has a light emitting element and a capacitive element. The first lighting circuit receives power supply from a first power source to light the light emitting element. The backflow prevention circuit interrupts a current flowing from the capacitive element in a direction of the first lightning circuit. |
