A fluorescent tube is made up of five primary parts:
Glass envelope (bulb itself)
The components of a fluorescent light.
Fluorescent light is derived from electrons that are emitted by an electrode at one end of the tube which collide with a free electron of an atom of mercury (a metal/conductor in gas form) inside the tube. This collision, which happens at high speed, produces ultraviolet radiation. The radiation, in turn, excites the phosphors coating the glass tube, which then emit light. Fluorescence is unlike incandescent light and doesn’t ...
