Abstract
An emergency power supply for lighting apparatuses and to a lighting apparatus for an emergency power supply. The emergency power supply () includes: a power supply () provided with at least one main insulation, e.g., transformer, (), operatively connectable to the network voltage; an accumulator () operatively connected to the power supply (); a flyback power converter () including a primary () and a secondary () provided within at least one additional insulation, e.g., transformer (). The primary () is connected to the accumulator () and the secondary () is directly connectable, except for the conversion network, to the output of a network power supply () and simultaneously to a light source (). A control unit (), which includes an transistor activation device (), is operatively connected to the power supply (), to the accumulator () and to the primary () of the flyback power converter () and is configured for detecting the network voltage and for switching the emergency power supply () between a first mode of deactivation of the flyback power converter () and a second mode of activation of the flyback power converter ().
