How does a HPS ignitor work?

The lamp comes in variations, but the most common way to start the lamp is with a pulse start. There is an ignitor built into the ballast which sends a pulse of high voltage energy through the arc tube….

What does an igniter do in a ballast?

HID lamp ignitors provide a brief, high voltage pulse to the lamp to ignite the gases inside. When accurately timed, they help the lamp start more reliably. Our selection of ignitors are designed to work with either high pressure sodium lamps or metal halide lamps that operate a wide range of wattages.

What is illumination Ignitor?

An ignitor is a starting device that generates voltage pulses to start a discharge lamp. Lighting ignitors provide a brief, high voltage pulse to ignite the gases inside lamps. They are designed to ensure the reliable and smooth starting behavior of lighting systems.

How do you test an HPS Ignitor?

Metal halide lamps do not require an ignitor to start, so the test for a failed ignitor for an HPS lamp is to screw in a metal halide bulb of the same wattage and see if it starts. If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced.

Can HPS bulbs explode?

The internal pressure of HPS and LPS is lower than that of the surrounding air, so there is no risk of explosion.

What the difference between a ballast and an ignitor?

The igniter functions as the firing mechanism for the bulb, the ballast functions as the power source to convert the car’s power into a usable source for the xenon bulb.

What is use of ignitor in HPSV lamp?

So there is no enough space to provide any starting electrode in the arc tube. So a higher voltage is required to initiate the arc. A ballast with igniter is used for this purpose. High voltage is fed to the lamp from the ballast by using the phenomenon of superimposing a low energy high voltage pulse.
