Ignitor

To ignite a high- pressure discharge lamp, it is necessary providing the lamp a defined ignition voltage. High-pressure sodium vapour (HS), metal halide (HI) and ceramic discharge metal Halide (C-HI) lamps usually needs much higher impulse voltages to be superimposed them. Ignitors generate this impulse voltage. The crucial points successful ignition of a lamp are peak value, pulse width, number and phase position of the ignition impulses.




Pulse Ignitor System

Pulse ignition systems utilize the winding of the inductive ballast to generate pulse. For this reason, the ballast must be capable of withstanding stress arising high impulse voltage. The additional design effort particularly applies to dimensioning creepage and clearance distances.



Softstart

The Ignitors are capable of withstanding any pulse loads that may occur because of extreme voltage and currents, as can happened particularly during the start of warm lamps or so called "flashing". The soft start protects the ignitor and ensures a maximum lamps life service.
