What is a lamp Ignitor?
Ignitors An ignitor is a starting device that generates voltage pulses to start a discharge lamp. Modern ignitors therefore normally incorporate anti-cycling control that can sense the normal end-of–life mode of a lamp and disables the ignitor.
What does an igniter do in a light fixture?
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.
What is the use of ignitor in metal-halide lamp?
Igniters are used for Metal-Halide lamps because they operate at a pressure between 4 and 20 atmospheres so require special fixtures to operate safely, as well as an electrical ballast and a special igniter to ensure a reliable and instantaneous lamp ignition.
How does an ignitor work?
When the button on a Piezo electric ignitor is pressed, a spring loaded hammer strikes quartz in order to start a fire. This is a typical process in lighters. A spark can be created by creating the necessary amount of voltage. The process creates enough energy to produce a spark.
What is the difference between ignitor and ballast?
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.
How do you test a high pressure sodium 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 Ignitor work?
I think it is a circuit that creates a spark to ignite the gas or start the arc or what have you. So it is literally an ignitor like you would see in an electric cigarette lighter. a lamp in which an electrical discharge in sodium vapour gives a yellow light, typically used in street lighting.
How does an ignitor on a lighter work?
It consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT. This sudden forceful deformation produces a high voltage and subsequent electrical discharge, which ignites the gas. An electric spark is usually generated once per turn of the knob or press of the button.
Is ballast and choke same?
A choke is an inductor designed to have a high reactance to a particular frequency when used in a signal-carrying circuit. An electrical ballast (sometimes called control gear) is a device intended to limit the amount of current flowing in an electric circuit. Ballasts vary greatly in complexity.
