Tube Light Circuit Diagram With Starter. How to install a single tube light with electromagnetic ballast. When the lamp first turns on the path of least resistance is through the bypass circuit and across the starter switch.
I explain how starter of tube light works use of glow starter with connection circuit diagram voltage and current waveforms in this video. From the junction box the neutral wire is not taken out to the switch board rather it is taken out from the junction box and carried out to the port 2 of the tube light as per figure above. 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.
A wire already connects port 2 and pin 1 of the terminal 2.
A wire already connects port 2 and pin 1 of the terminal 2. Here two tube lights are used in our case each one is 20 watts each tube light will have two filament with four terminals connect starter element to any on side of tube light after that link phase line to the ballast choke through switch. In this circuit the current passes through the electrodes on both ends of the tube. How to install a single tube light with electromagnetic ballast.
