Double tube light connection diagram. Here two tube lights are used in our case each one is 20 watts each tube light will have two. When an ac voltage is applied to a tube light fixture the voltage passes through the choke the starter and the filaments of the tube. A wiring diagram is a simplified standard pictorial representation of an electrical circuit. Double ended lamps use shunted lampholders so that the two contact pins on the live side of the lamp are shorted together creating no voltage difference between the pins. The fluorescent tube has two filaments with four terminals the. 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.
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. The energy focus commercial double ended ballast bypass debb led tube is a double ended lamp. The debb can be used with shunted or unshunted lampholders. We need tube light ballast starter and fluorescent light holders to make wiring connection. Assortment of t8 led tube light wiring diagram. 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.
The tube light or fluorescent light is a low pressure mercury vapor gas discharge lamp and it uses fluorescent to produce white light. Double tube light क connection कस कय जत ह इस video म circuit diagram बन कर दखय और बतय गय ह. So the neutral wire is continued from port 2 to pin 1 of terminal 2. How to install a single tube light with electromagnetic ballast. It shows the parts of the circuit as streamlined forms and also the power and signal connections between the gadgets. The starter is made up of a discharbe bulb with two electrodes next to it.
Tube light wiring diagram. Tube light circuit diagram electronic choke tube light circuit diagram without starter tube light connection with choke and starter two tube light series connection wire up a twin tube light. The starter is like a key of fluorescent light because it is used to light up the tube. This principle of the choke is exploited in lighting a fluorescent tube light.
