What is the purpose of ignitor in sodium Vapour lamp circuit?
Ignitors An ignitor is a starting device that generates voltage pulses to start a discharge lamp.
What is the purpose of inductor in high pressure sodium Vapour lamp circuit?
The inductor has two benefits: Its reactance limits the power available to the lamp with only minimal power losses in the inductor. The voltage spike produced when current through the inductor is rapidly interrupted is used in some circuits to first strike the arc in the lamp.
What is electrical ignitor?
An e-match or electrical igniter is an electrical device used to trigger pyro compounds, and is widely used in professional pyrotechnical displays. … This heat ignites a pyrogenous compound with which the igniter is encased.
What is the function of ignitor in HID lamps?
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.
Where is 250w high pressure sodium lamp used?
Main applications of the high intensity discharge lamp are usually found in the street lighting, stadium, highways, industrial lighting, and airport lighting.
Which ballast is used in sodium lamp?
Operation. The inductive ballast is made up of a coiled wire. The coil creates a magnetic field inside when a current is applied. It stores the energy of the current in the magnetic field it creates.
What is the purpose of ignition system?
ignition system, in a gasoline engine, means employed for producing an electric spark to ignite the fuel–air mixture; the burning of this mixture in the cylinders produces the motive force.
What is the function of ignition coil?
The ignition coil acts like a transformer. By means of two coils, one inside the other, the ignition coil transforms the electrical energy from the vehicle battery into high voltage, saves it briefly and then emits it as a high voltage current pulse to the spark plug.
How does an ignition work?
Once the ignition switch is prompted by key or the push of a button, it activates the voltage from the battery to the ignition coil to produce the engine spark. The engine spark from the coil or coils is directed to the spark plugs to ignite the fuel to make the vehicle run.
