Lighting apparatus, driving method of lighting apparatus, and vehicle lamp

A lighting apparatus includes: a first light emitting element; a second light emitting element whose emission color is different from that of the first light emitting element; a power supply circuit connected to and supplies a driving voltage to the light emitting elements; and a control circuit configured to control flow of a current generated by the drive voltage to each light emitting element, and to control the flow of the current such that, during a first period, a first current flows through the first light emitting element while the second light emitting element is in a non-conductive state, and during a second period, a second current smaller than the first current flows through the first light emitting element while a third current flows through the second light emitting element.
