Abstract

The emergency electricity power supply includes a battery B which feeds a DC-DC converter delivering an output current which varies as an inverse function of the output voltage. Thus it can supply both high current at low voltage for heating the filaments and low current at high voltage for running the lamp once triggered. The DC-DC converter comprises a control unit (2), eg an IC of the 555 type, which delivers signals of predetermined duration to a transistor (T3) in series with the primary (E1) of a transformer whose secondary winding powers the lamp via a diode (13). An inhibitor unit (15) is controlled by the voltage at the transistor collector and delivers an inhibiting signal to the control unit during a period required for recovering in the secondary winding the energy stored in the primary winding, this period being inversely proportional to the voltage at which the energy is recovered. A circuit (20) is triggered by an overvoltage at the transistor collector to inhibit the central unit.
