What is the purpose of a choke in tube light?
The vapor gets excited and produces ultraviolet radiation which interacts with the phosphor coating on the inner walls of the tube light and the phosphor produces the glow of the light emanating from the tube light. A choke coil is used to produce this high voltage across the tube.
Can we use Tubelight without starter?
Yes, as long as the gas is ionized and you have the voltage under control. Starters and starters are just tools to perform ionization. If you have other tools to achieve the same result, you are doing it right.
What is the function of choke in carburetor?
A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine.
Does the tube glow without starter if yes how?
Yes, as long as the gas is being ionized and you have control over the voltage. Choke and starters are just ‘tools’ to achieve the ionization. If you have other tools to achieve the same result, then you’re doing it right. It can also be achieved by heating the gas.
What happens if choke is left on?
Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. The engine needs its fuel to be vaporised in order to burn it. This is done by the carburettor where the fuel is mixed with clean air coming from the air filter, and sent into the pistons to be ignited.
Should choke be open or closed?
The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in. Once the car has warmed up, if the choke does not open fully, the restriction in air may result in reduced power.
What happens if the starter is removed after the lamp glows?
Tube light will not become off if you remove starter. The starter is required only at beginning to make light to glow. If you remove starter while the light is glowing it will not affect the light. The light will continue to glow.
What is choke in fluorescent lamp?
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.
Can you bypass ballast for LED lights?
Since LED lights work on low DC voltage, they need a driver. Most T8 LED tubes do not need a ballast. So, if you are going to install a T8 LED tube light, it will require a ballast bypass unless you choose a ballast compatible T8 LED tube.
How do you wire LED tubes without ballast?
How to Bypass A Ballast
- Step 1: Disconnect All Power So There is No Electrical Current.
- Step 2: Find the Ballast.
- Step 3: Locate and Cut Only the Hot and Neutral Wires.
- Step 4: Cut the Socket Lead Wires.
- Step 5: Remove the Ballast (if you wish)
- Step 6: Connect the Wires.
- Step 7: Reattach Any Coverings and Turn On.
What does a choke do on a tube light?
The choke or the ballast for that matter is basically an inductor which is connected in series with the starter and the basic function performed by the choke is the limiting of the current flowing once the starter is connected and when the tube light is on, that is after the starter is disconnected.
How does a mercury tube light work?
When power is applied to the light, current flows through the the heaters at the end of the tube (s) to volatilise some of the mercury in the tube. After a second or two, the contacts in the starter open, and the current through the choke drops to zero.
What is a a choke?
A choke is a coil of wire. Fluorescent tubes/lamps are filled with mercury vapor. They use electric charge to excite mercury atoms in order to produce ultra violet light.
How does a fluorescent tube light work?
A fluorescent tube has filaments at either end: these filaments warm up at switch on, and thermostatically cut off after a warming delay. The current through the start choke generates an EMF spike large enough to initiate a discharge through the vaporized mercury vapor which continues each half cycle.
