Cold cathode - Wikipedia
WEBA cold cathode is distinguished from a hot cathode that is heated to induce thermionic emission of electrons. Discharge tubes with hot cathodes have an envelope filled with low-pressure gas and containing two electrodes.
The Cold Truth About Cold Cathode Lighting – GoodBulb
WEBA cold cathode fluorescent lamp (CCFL) is a lighting system that utilizes both fluorescence and electron discharge in order to produce light. This means they operate similar to a standard fluorescent lamp, by exciting electrodes, but they just go about it differently.
