Abstract
An LED lighting apparatus is provided. The apparatus has an LED luminous unit having multiple plurality LEDs and a switching arrangement. The LED luminous unit has different forward voltages in different switching states. The apparatus also has a control device for driving the LED luminous unit and a current sink device in a normal operating mode, in which the forward voltage and the LED current of the LED luminous unit are adapted to an instantaneous value of a supply voltage. An energy storage module of the apparatus provides a storage voltage and supplies the storage voltage to the LED luminous unit. The control device drives the LED luminous unit and the current sink device in a storage operating mode, such that the forward voltage and the LED current of the LED luminous unit are adapted to an instantaneous value of the storage voltage.
