Abstract:
An emergency power supply for lighting apparatuses and to a lighting apparatus for an emergency power supply. The emergency power supply ( 1 ) includes: a power supply ( 11 ) provided with at least one main insulation, e.g., transformer, ( 34 ), operatively connectable to the network voltage; an accumulator ( 16 ) operatively connected to the power supply ( 11 ); a flyback power converter ( 17 ) including a primary ( 18 ) and a secondary ( 19 ) provided within at least one additional insulation, e.g., transformer ( 30 ). The primary ( 18 ) is connected to the accumulator ( 16 ) and the secondary ( 19 ) is directly connectable, except for the conversion network, to the output of a network power supply ( 2 ) and simultaneously to a light source ( 3 ). A control unit ( 20 ), which includes an transistor activation device ( 27 ), is operatively connected to the power supply ( 11 ), to the accumulator ( 16 ) and to the primary ( 18 ) of the flyback power converter ( 17 ) and is configured for detecting the network voltage and for switching the emergency power supply ( 1 ) between a first mode of deactivation of the flyback power converter ( 17 ) and a second mode of activation of the flyback power converter ( 17 ).

Claim (Index 1):
An emergency power supply apparatus for lighting apparatuses comprising:\n a power supply operatively connectable to a network voltage and including at least one main insulation; an accumulator operatively connected to the power supply; a flyback power converter including a primary having an electronic switch and a secondary, wherein the primary is connected to the accumulator, and the secondary, provided within at least one additional insulation, is electrically and directly connected to cables between a network power supply and a light source of a lighting apparatus, due to the main insulation and to the additional insulation; wherein said flyback power converter is configured for to directly transfer to an output circuit energy without switches/relay; a control unit operatively connected to the power supply, to the accumulator and to the primary of the flyback power converter and configured to detect the network voltage and to switch 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, wherein in the second mode, the flyback power converter works discontinuously at the switching frequency of the electronic switch; wherein the control unit comprises an activation device configured to activate the flyback power converter.
