What is an ignitor in lighting?
Ignitors An ignitor is a starting device that generates voltage pulses to start a discharge lamp. … This normally happens after the ignitor has tried to start the lamp a few times, and for metal halide lamps this is generally after approximately 15 minutes.
What is the function of Ignitor?
Subsequently, one may also ask, what is the function of Ignitor? An ignitors provide the high-striking voltage needed to ignite a UV lamp when used on a UV system powered by chokes. Chokes and ignitor circuits can be used to power lamps up to 500mm in length.
How does a lamp 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.
What is a ballast Ignitor?
“Ballasts provide system stability by limiting the current that can be drawn.” Ignitors: “Ignitors provide a brief, high voltage pulse or pulse train to breakdown the gas between the electrodes of an arc lamp.
What are the symptoms of a bad igniter?
Symptoms of a Bad or Failing Ignition Ignitor
- Engine misfires and decrease in power, acceleration, and fuel efficiency. One of the first symptoms of an issue with the vehicle’s igniter is engine performance issues. …
- Check Engine Light comes on. An illuminated Check Engine Light is another symptom of a potential issue with the vehicle’s igniter. …
- Car is not starting.

Why do fluorescent lights need a capacitor?
Fluorescent lamps form an inductive load on the AC mains supply. As a result large installations of such lamps suffer a poor power factor and resultant voltage drop. Adding a capacitor to each lamp corrects the power factor bringing it back close to unity (1.0).
What is a Ignitor?
The ignition ignitor is the component that is responsible for sending a signal from the key’s ignition switch to the electrical system to supply power to the spark plugs and start your engine. … In some systems the igniter is also responsible for advancing and retarding the engine’s timing.
How do I know if my ignition control module is bad?
Signs of a Bad Ignition Module
- Acceleration Issues. The vehicle may shake, vibrate or jerk when the gas pedal is pressed. There may be hesitation or lack of power during increases in speed.
- Temperature Problems. A faulty ignition module can cause a vehicle to overheat. …
- No Power. The engine may turn over without starting.
What is the mileage of Hero Ignitor?

Why do sodium lamps take time to glow?
Due to the presence of neon, the colour of light is at first red until the lamp temperature rises to a stage at which sodium gets vapourized. … It takes some time, say, 5 minutes for the lamp to glow at its full intensity due to the gradual vaporization of sodium.
What gas is used in street lights?
Sodium-vapour lamp, electric discharge lamp using ionized sodium, used for street lighting and other illumination. A low-pressure sodium-vapour (LPS) lamp contains an inner discharge tube made of borosilicate glass that is fitted with metal electrodes and filled with neon and argon gas and a little metallic sodium.
Is sodium lamp a coherent source?
act as coherent sources? Explain in brief. Yes, two sources which emit light of same wavelength, same frequency and equal intensity or amplitude in the same direction are coherent sources.
What does a capacitor do in a ballast?
Capacitors, available in both oil-filled and dry-film technologies, are used with some HID ballasts in order to improve their power factor, light output, and even efficiency by regulating the inrush current that occurs when the light is initially started.
What happens when a ballast goes bad?
When your fluorescent light flickers or makes a loud and annoying hum, a degrading ballast is the cause. The ballast takes in electricity and then regulates current to the bulbs. A typical ballast will generally last about 20 years, but cold environments and bad bulbs can decrease this lifespan significantly.
What does a headlight igniter do?
The igniter is much like a voltage amplifier, the component in an HID lighting assembly that amplifies the voltage supplied to the light upon turning it on. Once on, the voltage going to them is lowered. The headlight igniter is the component that increases the voltage to operate the HID light.
