ELECTRIC DEVICE FOR PRIMING AND POWERING A LOW PRESSURE DISCHARGE LAMP, AND LAMP UNIT PROVIDED WITH SUCH A DEVICE

摘要

ELECTRICAL DEVICE FOR THE PRIMING AND POWERING OF A LOW PRESSURE DISCHARGE LAMP 5 WITH TWO ELECTRODES 4, 6 BETWEEN THE MAIN DISCHARGE PATH 16, 17, 18, 19, WHEN THERE IS PARALLEL TO AT LEAST ONE PART OF THIS MAIN DISCHARGE PATH, IS MADE A SLOTTED PATH. / P P IN ACCORDANCE WITH THE INVENTION, THE LAMP IS PRIMED USING A LIGHT STARTER 8 SHUNTE BY A VDR 7, WHOSE THRESHOLD VOLTAGE IS LESS THAN A VALUE DETERMINED BY THE GEOMETRY OF THE SLOTTED TRACK, AND IS GREATER THAN THE MINIMUM VOLTAGE NECESSARY TO BEGIN A DISCHARGE IN THE MAIN DISCHARGE TRACK. IN THIS CASE THE DISCHARGE WILL ONLY START ON THE MAIN DISCHARGE PATH. / P
