Function of Starter in Tube Light Circuit

In a tube light circuit, the starter is an important component that helps the fluorescent lamp start up.

It has the following functions:

Heat the Filaments

When you turn on the tube light, the starter links the filaments at both ends, allowing a modest current to pass through them. This current warms the filaments, which is required for the lamp to properly ignite.

Generating a High Voltage Pulse

After a brief delay, the starter interrupts the circuit, triggering an inductive kick from the ballast and a high voltage pulse. This high voltage is required to ionize the gas inside the tube light & begin the flow of current through the tube, which ignites the lamp.

Providing Reliable Ignition

The starter enables a consistent and dependable lighting process by opening and shutting the circuit repeatedly until the tube light ignites.

In summary, the starter assists in preheating the filaments and providing the high voltage required to ignite the fluorescent tube light.
