Fluorescent lamp

OverviewPrinciples of operationHistoryPhosphors and the spectrum of emitted lightApplicationsComparison to incandescent lampsDisadvantagesLamp sizes and designations

The fundamental mechanism for the conversion of electrical energy to light is the emission of a photon when an electron in a mercury atom falls from an excited state into a lower energy level. Electrons flowing in the arc collide with the mercury atoms. If the incident electron has enough kinetic energy, it transfers energy to the atom''s outer electron, causing that electron to temporarily jump …
