Nisam dovoljno strucan da napisem kako se zovu te sijalice, no uglavnom one se svakako gase i pale same, kad se pregreju. Mislim da se zovu Zivine. Raspitajte se kod nekih koji rade u elektrodistribuciji, ali nemojte im ispracati ovo sto ste ovde napisali.
I ja sam to video, ali nisam primetio da se bas ona kod koje se nalazim ugasila. Isto tako ne mora znaciti da se bas uvek sama od sebe ili pregrejanosti ugasi. Mozda je neko od vas stvarno pripomogao da se bas onda pregreje i ugasi.
Citat:
At the end of life, high-pressure sodium lamps exhibit a phenomenon known as cycling, which is caused by a loss of sodium in the arc. Sodium is a highly reactive element, and is easily lost by combination with other elements, and migration through the arc tube walls. As a result, these lamps can be started at a relatively low voltage but as they heat up during operation, the internal gas pressure within the arc tube rises and more and more voltage is required to maintain the arc discharge. As a lamp gets older, the maintaining voltage for the arc eventually rises to exceed the maximum voltage output by the electrical ballast. As the lamp heats to this point, the arc fails and the lamp goes out. Eventually, with the arc extinguished, the lamp cools down again, the gas pressure in the arc tube is reduced, and the ballast can once again cause the arc to strike. The effect of this is that the lamp glows for a while and then goes out, repeatedly.
Najcesca pojava tog on/off ciklusa je kod natrijevih lampi.
I meni se dežavalo da se kad prođem pored neke ili upali ili ugasi. Veoma je vjerojatno da smo mi na neki nacin uzrok njihovog gađanja ili paljenja. Pošto se ipak nalazimo u polju jedni drugih. Ali sad koliki je taj faktor našeg utijecaja na to. To je ono što je zbilja ušitno. Ali svakako je je fora ici ulicom i svaka lampa pored koje proeš se ugasi. Dobar feel!
