Abstract

1414051 Standby supply systems for gas discharge lamp GENERAL ELECTRIC CO 24 May 1973 [24 May 1972] 24782/73 Heading H2H A standby power supply system for discharge devices such as gas discharge lamps comprises a ballast device by way of which the discharge devices are operated from a primary power source and an emergency power source connected to the discharge devices when the primary power source fails, the emergency power source operating at a high frequency such that the ballast device exhibits a high impedance and the emergency power source having a high impedance at the frequency of the primary power source. A lighting system 24 comprises two discharge lamps 66, 67 having heatable electrodes and connected in series between terminals B, C, the lamp 66 having a capacitor 70 connected in parallel therewith. A normal power source is connected to terminals 10 and to terminals 15 the supply at terminals 10 operating the two lamps 66, 67 in the normal way through an inductive ballast 12, whilst the supply at terminals 15 provides signals to inhibit the transistors 25, 26 of an inverter and at the same time charge a battery 35 which forms the emergency source of power. Failure or reduction in voltage of the primary source of power at terminals 10, 15 removes the inhibiting signals on the transistors 25, 26 whereupon the inverter 16 begins to oscillate, the power being supplied by the battery 35. The output frequency of the inverter at the secondary winding 36 of the transformer 30 is of the order of 6À5 kHz and at this frequency the capacitor 70 is effectively a short circuit so that the inverter 16 causes illumination of the lamp 67 only at a reduced light output. At the output frequency of the inverter 16 the ballast 12 forms a high impedance and capacitors 46, 47 which are connected in series with the secondary winding 36 cause the inverter 16 to form a high impedance when the lamps 66, 67 are supplied from the normal power source at terminals 10.
