How does a HPS ignitor work?
There is an ignitor built into the ballast which sends a pulse of high voltage energy through the arc tube. This pulse starts an arc through the xenon gas. The lamp turns sky blue as the xenon lights. The arc then heats up the mercury and the mercury vapor then lights, giving the lamp a bluish color.
How do you test a 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.
What is the purpose of ignitor in high pressure sodium Vapour lamp?
Ignitors An ignitor is a starting device that generates voltage pulses to start a discharge lamp.
How does a lamp ignitor work?
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.
Do high pressure sodium bulbs need a ballast?
HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. HPS lamps do not contain starting electrodes. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.
What causes a high pressure sodium light to go on and off?
A high pressure sodium lamp cycling on and off usually indicates the lamp has reached the end of its normal life.
What does a capacitor do in a ballast?
The ballast units are generally composed of a transformer to reduce the incoming voltage, a small capacitor (that may contain PCBs) and possibly a thermal cut-off switch or safety fuse. PCB were used as liquid insulators in electronic equipment.
Will a metal halide ballast work with a high pressure sodium bulb?
The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange. These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs.
How do I know if my ballast is working?
One probe of the multimeter should touch the hot wire connections, while the other touches the neutral wire connections. If the ballast is good, an analog multimeter has a needle that will sweep to the right across the measuring scale. If the ballast is bad, then the needle won’t move.
How do HPS ballasts and ignitors work?
How does hps ballasts and ignitors work? High pressure sodium ballasts for lamps provide stable current use of the inductive reactance of the ballast, and other pipe lit work. Ballast for the lamp to provide a high starting voltage, lamp conduction.
What is HPS HID high pressure sodium lamps?
HID High Pressure Sodium lamps features high quality and reliability. HPS lamps are highly efficient light sources-offering more light per watt than comparable incandescent and most fluorescent light sources. HPS HID sources feature long life-much longer than most incandescent sources and even longer than fluorescent lamps.
What are the advantages of a HPS HID Source?
HPS HID sources feature long life-much longer than most incandescent sources and even longer than fluorescent lamps. They are a compact, point source like incandescent, allowing good optical control.
