I have a tubelight in my house . Whenever I switched on it , it starts producing a huge sound . If the surrounding area is quite , its volume is so high that I am not able to hear the sound of tv also !
I decided to do some research on the topic .
There are 2 sources of noise in a tubelight .
1 . Choke
2. Tube holder
Choke is on the center of tube light . What we see a rectangular structure at the centre of the tube light is known as the choke .
Choke is used to reduce the current flow to the tube . Current is generally controlled by using an inductor coil or a transformer .
When the choke is used for many days , the transformer inside it gets faulty . It starts to lose its magnetostriction effect in its core , hence producing a buzzing sound .
If we use an electrical choke , we can minimize the sound .
2 . Tube holder ---- Tube holder is the place where the choke is placed . It is usually made of ferrous material . When leakage magnetic field of choke acts on it , certain parts of it gets magnetized thus creating the mechanical stress . This stress produces buzzing sound .
