摘要： An LED power supply device may include a power supply to control an LED component, a control unit to control the power supply, the control unit having a control interface for applying external control signals to the power supply, and a voltage supply unit connected to a connection of the power supply, wherein the control unit receives operating voltage from the voltage supply unit for continuous operation in an activated and non-activated control state of the LED component, wherein the voltage supply unit comprises a capacitor coupled to an output side of the power supply, the capacitor configured to supply a capacitor voltage as operating voltage to the LED power supply device, and wherein the control unit is configured to charge the capacitor using pulse-like control of the power supply such that, in the non-activated control state, a maximum charging voltage lies below the LED threshold voltage.

摘要： An LED power supply device includes a power supply to control an LED component, a control unit (with control interface) to control the power supply, and a voltage supply unit connected to a connection of the power supply. the control unit receives operating voltage from the voltage supply unit for continuous operation in an activated and non-activated control state of the LED component, and the voltage supply unit uses a capacitor coupled to an output side of the power supply to supply a capacitor voltage as operating voltage to the LED power supply device. The control unit is configured to charge the capacitor using pulse-like control of the power supply such that, in the non-activated control state, the maximum charging voltage lies below the LED threshold voltage.
