It is the boiling off of electrons from the filament of the cathode.

thermionic emission is the process of boiling of electrons and it happends in the filament . filament is loacated in the cathode side of xary tube. when 3-5 amp or 10-12 volts goes to the filament from step down transformer, the filamnet will heat up a and it glows
