CIRCUIT ARRANGEMENT FOR OPERATING A LOW-PRESSURE GAS DISCHARGE LAMP AND CORRESPONDING METHOD

摘要

PURPOSE: The circuit arrangement and the corresponding way for activating the low-pressure gas discharge lamp detect the voltage drop of the primary both ends of winding of transformer for the preheating phase. CONSTITUTION: The input unit(2) comprises the first input connection unit(3) and the second input connection(4) for sanctioning the DC supply voltage. The output unit(16) comprises the first output connection portion pair(17) and the second output connection portion pair(18). The inverter(6) offers the AC supply voltage from the DC supply voltage.
