Claim:
1. A lighting device, comprising: a rectifier circuit configured to rectify a sine wave AC voltage inputted between a pair of input terminals of the rectifier circuit, and output a pulsating voltage from between a pair of output terminals of the rectifier circuit; a current control circuit electrically connected in series to a light source between the pair of output terminals, and configured to control a current flowing in the light source such that the current does not exceed a predetermined value; a storage element; a charging current control circuit configured to control a charging current that flows to the storage element, the storage element being electrically connected in series to the charging current control circuit between two ends of the current control circuit; a first rectifier element that is for causing the charging current to flow to the storage element via the light source and not via the current control circuit; a second rectifier element that is for causing a discharge current that is discharged from the storage element to flow in the light source; and a third rectifier element that is for causing the discharge current to flow bypassing the charging current control circuit.
