Abstract

A driving circuit includes a first driving switch, a second driving switch and a current regulating unit. The first driving switch is electrically connected to a first power source and a first light emitting element. When the first driving switch is turned on, the first driving switch is configured to receive a first current. The second driving switch is electrically connected to a second power source and a second light emitting element. When the second driving switch is turned on, the second driving switch is configured to receive a second current. The current regulating unit is electrically connected to a negative terminal of the second light emitting element and a positive terminal of the first light emitting element. When the current regulating unit is disabled, the second current sequentially flows through the second light emitting element and the first light emitting element.
