Why choke is necessary for tube light in DC circuit?
Choke is an inductor; hence it acts as a pure inductor. Inductor is having the properties of creating high voltage at stating. This high voltage is enough to trigger the tube lights starter.
What is the use of choke and starter in tube light?
Why Choke Is Used In Tube Light The choke also plays a very important role in tube light. If there is no choke in tube light then the tube will get blast due to heavy current flow. The main purpose of the choke is to limit the current flow. The choke is connected in series with the phase wire.
How do you fix a tube light without a starter?
If you do not find a starter, unplug the light or shut off the power, then remove the deflector above the tube and look there, or disassemble the base if the light is a desk or floor model. To remove a starter, press it inward and twist it counterclockwise a quarter turn; it should pop out.
What is choke in fluorescent light?
The choke primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive ‘kick’ forming a momentary higher-voltage pulse to start the lamp.
What is tube light starter?
Fluorescent starters or glow starters are used to help fluorescent tubes and lamps ignite in the initial starting stage of their operation. Simply put, fluorescent starters are a timed switch. The switch opens and closes until the fluorescent tube ‘strikes’ and lights-up.
What is a Tubelight starter?
A fluorescent starter is a simple timed switch that allows the flow of current in the filaments of fluorescent light. The current heats up the contact of the starter, turning its switch on and off until the fluorescent tube lights up.
What is the voltage required to start a fluorescent lamp?
Fluorescent starter: Fluorescent starters are a timed switch and it provides ignition voltage to the fluorescent lamp. The ignition voltage is as high as 1000 V to initiate a discharge in the argon gas lying between electrodes.
How do you start a fluorescent light?
The tube just needs a voltage kick across the electrodes to establish an electrical arc. This kick is provided by the lamp’s ballast, a special sort of transformer wired into the circuit. When the current flows through the bypass circuit, it establishes a magnetic field in part of the ballast.
How do you start a fluorescent light without a starter?
What is the use of fuse in fluorescent tube?
Fluorescent light bulbs are commonly used in photographic light and kitchen light fixtures. A fuse is the first place to check when a fluorescent light fixture will not light up after the switch is turned on. When the fuse is blown, electricity cannot flow from the power source into the lamps inside of the bulb.
What is tube light choke?
The purpose of the choke is to provide a very high voltage initially between the filaments (across the two ends of the tube light). Again once the gas in the tube is ionized the choke provides a low voltage. A choke is a coil of wire. Fluorescent tubes/lamps are filled with mercury vapor.
How can I start a tube light without a choke?
Tube light can’t work without choke. CHOKE is a circuit which provide higher frequencies (in Khz) for operation, the new name for the choke is ‘electronic ballast ‘ which is light weight and efficient. Originally Answered: how can we start-up the 40w tube light with 230v AC/DC without using any choke/coil?
What happens when a choke is connected to a tube light?
A choke is connected in one end of the tube light and a starter is in series with the circuit. When supply is provided ,the starter will interrupt the supply cycle of AC. Due to the sudden change of supply the chock will generate around 1000volts .
Can bulb be used with DC supply?
Bulbs [devices] for AC are designed to operate such that it offers high impedance to AC supply. Normally they have low resistance. When DC supply is applied, due to low resistance, the current through lamp would be so high that it may damage the bulb element. 15.
Can a fuse be used in the phase of AC circuit?
But in the case of Fuse in the Phase of AC circuit it is designed such that the fuse rating is calculated for the particular circuit (i.e load) only.So if any malfunction happen the fuse connected in the particular control circuit alone will blow off. 5.
