Abstract

Inventia de fata se refera la un catod pentru tuburi fluorescente, care este montat permanent în legatura cu peretele tubului si care este închis cu un ecran ce consta dintr-un material electroconductor si care nu este conectat electric la catod. Mantaua catodului este formata dintr-o carcasa în forma de cutie, la baza careia este practicata o deschidere, iar capatul deschis al cutiei este închis cu ajutorul unui disc din material electroizolant, prevazut cu un orificiu central avînd un diametru cît de mic posibil, tinînd cont de faptul ca tensiunea initiala în tub nu poate depasi o valoare prestabilita si ca deschiderea de la baza ecranului catodului are o suprafata care este cel putin la fel de mare ca orificiul discului.
