Here two tube lights are used in our case each one is 20 watts each tube light will have two. Connect live end of replacement led tube lamp.
How To Replace Fluorescent Tube Lamps With Led T8 Tubes
Two tube light series connection. The two electrical contacts can either be. Once the right resistor is selected we can connect the resistor in series and give the 12v supply to the led. I not connected to any electrical source ii one connected to live the other connected to neutral iii both connected to live or neutral scenario ii is called non shunted while scenario iii is called. Here you can see there is a cut in the line wire connected to lamp 3 so the bulb is switch off and the rest circuit is working. 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. This article gives a details about double tube light connection by using single ballast or choke some electronic choke not support this connection check the ballast specification and watts level before make this type of connection.
Circuit 2 of simple led circuits leds in series the next circuit in the simple led circuits project is connecting leds in series. We need tube light ballast starter and fluorescent light holders to make wiring connection. So the neutral wire is continued from port 2 to pin 1 of terminal 2. A wire already connects port 2 and pin 1 of the terminal 2. Reconnect the load and neutral wires to 85 145vac power source. Tombstones have two electrical contacts to match the two pins on a fluorescentled tube light.
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. In this circuit we will connect three 5mm white leds is series with the same 12v supply. Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below. 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. How to install a single tube light with electromagnetic ballast. Connection instructions led tube light installation ballast bypass electronic ballast type ballast l n cut cut cut load and neutral output wires from other end of ballast and discard as the led lamp only requires power from one end.
The starter is like a key of fluorescent light because it is used to light up the tube.
