Please refer to the circuit diagram on the right as you read the following points. A fluorescent tube has a filament at each end just like the filament in an incandescent bulb but very.
Electronic Ballast Wiring Diagram H1 Wiring Diagram
Tubelight wiring with starter. Double tube light circuit diagram tube light circuit. In a non electronic ballast fluorescent light. No lumen output from the lamp. The starter is like a key of fluorescent light because it is used to light up the tube. A glow starter or commonly known as starter is used in the tube light circuit to provide an initial current to filaments of the tube light. The starter is a switch that is normally open that closes a few seconds after power is applied.
No discharge happens initially ie. When the switch is on full voltage will come across the tube light through ballast and fluorescent lamp starter. The fluorescent tube has two filaments with four terminals the starter is connected between two filaments the ballast is connected between main ac supply and one filament in tube light. Since the lighted fluorescent tube has a low resistance the ballast now serves as a current limiter. The starter which is simply a timed switch allows current to flow through the filaments at the ends of the tube. When we connect the ac supply voltage to the circuit then the starter act like short circuited and current flow through those filament located at the first and second end of the tube light and the filament generate heat and it ionized the gas mercury vapor in the fluorescent tube lamp.
Electronic ballast has six ports two ports out of six ports are for the input and the remaining four ports are for output ports. The choke is in fact a large. We need tube light ballast starter and fluorescent light holders to make wiring connection. Here is one example of a tube light fixture consisting of a large heavy square choke or ballast and a small cylindrical starter lets try to understand how the whole system works. Working principle of tube light. The current causes the starters contacts to heat up and open thus interrupting the flow of current.
The starter is a small neon glow up lamp that contains a fixed contact a bimetallic strip and a small capacitor. Tube light wiring diagram. Wiring of flourescent lights. How to install a single tubelight with electromagnetic ballast. As no starter is used in the case of electronic ballast application the wiring diagram is slightly different.
