What is a fluorescent starter and how does it work? - Ledkia UK

A starter is a small device used in certain types of lighting, especially fluorescent tubes. It usually consists of a small glass container with argon gas inside and a bimetallic foil.Basically, a fluorescent starter generates a sufficient discharge to “activate” the gas inside the lamp so that it lights up. Let’s take a closer look at how this process occurs.Table of ContentsHow the starter of a fluorescent tube worksElements of a fluorescent starterTypes of startersFluorescent tubes without a starterLED starters: what are they really?How the starter of a fluorescent tube worksWe can say that the starter of a fluorescent tube is simply a thermal switch. When the plug is pressed and the current is allowed to flow, it reaches the tube through the ballast and the starter itself.Inside the tube the circuit is closed through the filaments. At this time the starter is behaving like an open switch and therefore the current flowing through the circuit is very small.The voltage causes the temp...
