Claims (1)

1. power for from a lew DC voltage an electric lamp having a starting and a voltage operating an oscillator circuit including a switching device connected tc convert the low and a having a primary winding in series with switching device so as build u energy therein during the the switching device is conducting and to release the energy therefrom when the switching device is said transformer having a first secondary winding which is induced a voltage cemtrolling and a winding in which is a voltage o the electric discharge the inductance winding controlling the frequency of the oscillator and affected by said second secondary winding so that an in the current through the latter decreases the of the whereby before the electric lamp the oscillator oscillates at a high thereby producing a high starting voltage electric discharge and upon conduction of the electric discharge the high current lowers the the oscillator thereby producing a lower operating voltage the electric discharge A power supply g to Claim wherein the transformer includes secondary for preheating the electrodes of the electric discharge A power supply according o Claim w erein one of the electric discharge lamp electrodes is preheated by a series connection from said first secondary winding the switching and the other of the electric discharge lamp electrodes is preheated by a third secondary winding on the A power supply according to any one of Claims wherein said switching is a transistor having a connection between its base and emitter to said first secondary A fluorescent lamp and a supply in accordance with any one of Claims energizing An electrical insect exterminator comprising an electric discharge lamp for attracting an electrical grid for electrocuting and a power supply in accordance with any one of Claims for energising the electric discharge the transformer of the power supply including a further secondary winding in which is induced a high voltage for energizing the electrode An electrical insect exterminator according to Claim wherein said further secondary winding includes a voltage A power supply for energizing an electric discharge lamp from a low voltage substantially as described with reference to and as illustrated the accompanying substantially as as la drawings For Applicants PARTNERS insufficientOCRQuality
