摘要

Improvements in the object of the patent 407,217 for improvements in the bipolar electronic starters for the fluorescent lamp priming, particularly according to claim 1 of said patent, characterized in that the bipolar electronic starter has a second bidirectional electronic switch, mounted in series with the first electronic bidirectional driving switch, and a second threshold firing circuit for sending control pulses to the control input of this second electronic switch, and because the capacitor of the first threshold firing circuit and the means capable of sliding the potential are common to both threshold trigger circuits.
