Abstract
A lighting apparatus for an AC voltage supply is provided. A rectifier module of the apparatus converts an AC voltage from the AC voltage supply into a rectified supply voltage. A diode cascade of the apparatus has multiple diode cascade sections connected in series and each having an LED. Each diode cascade section has a connectable bypass device for bypassing the diode cascade section. The diode cascade section is in an illuminated state when the bypass device is deactivated and a dark state when the bypass device is activated. A current source module is provided for stabilizing the cascade current through the diode cascade to a setpoint value. At least one diode cascade section has a control device, which has a switching device for converting the detected illuminated state into a switching signal for reducing the setpoint value.
