Development of method of emitter application on the electrodes of gas-discharge lamps with preliminary heating

Abstract

The method of emitter application on the electrodes of gasdischarge lamps by dipping them in the emitter suspension with
preliminary heating has been developed. Experimental studies were
carried out on electrodes of DRL-250 lamps on study the effect of
preliminary heating on emitter weight gain, applied on the electrode
and the degree of filling electrode internal cavities with emitter on
the base of which the technology of emitter application on the electrodes of gas-discharge lamps with the preliminary heating has been
offered. The article also gives the results of experimental tests and
obtained the comparative characteristics for methods of applying
the emitter on electrodes in HID lamps with the preliminary heating.
