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 16):
A method to provide a lighting apparatus with an emergency power supply, the method comprising:\n providing a lighting apparatus comprising a network power supply and a light source connected to the network power supply; providing an emergency power supply comprising:\n a power supply operatively connectable to the network voltage and isolated from the network voltage by at least one main transformer; \n an accumulator operatively connected to the power supply; \n a flyback power converter comprising a primary having a transformer and an electronic switch, wherein the transformer includes a primary connected to the accumulator and a secondary; \n wherein said flyback power converter is configured for directly transferring to the output circuit the energy produced without switches/relay; \n a control unit operatively connected to the power supply, to the accumulator and to the primary of the flyback power converter and 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, \n wherein in the second mode, the flyback power converter works discontinuously at the switching frequency of the electronic switch; \n wherein the control unit comprises an activation device configured to activate the flyback power converter; \n said method further comprising connecting, directly in parallel, the terminals of the secondary of the flyback power converter of the emergency power supply to the cables which are extended between the network power supply and the light source.
