The cause of the noise of a fluorescent lamp?
Can unload the fluorescent lamp to first, open the cover of the ballast, then with a knife around the edge of the ballast pick to open a small mouth, will melt wax or resin pouring into the crevice ballast iron core silicon steel sheet
The old ballast is coiled and iron. Because the iron is pieces of encase with insulating varnish and stick in a piece, ballast fever after use for a long time, for the paint failure between iron, alternating current (ac) to produce magnetic field makes the debonding of the plate vibration, sound.
This reduces the vibration of the iron core and makes the noise smaller or disappear. The ballast can also be separated from other objects by rubber sponges and stents
The daylight lamp is used for a long time, making a squeaky or buzzing noise, which is the hum of the fluorescent lamp ballast. The vibrator of the iron core in the ballast is larger and the noise is increasing. Such cases require maintenance or replacement of the ballast.
