Kaarivalaisimia
Kaarivalaisimia, often translated as arc lamps, are a type of electric lamp that produces light by an electric arc between two electrodes. This arc is a sustained electrical discharge through a gas, typically air or a noble gas, that heats the gas to incandescence. The light emitted is intense and has a continuous spectrum. Early arc lamps were a significant source of artificial light before the advent of incandescent and fluorescent lamps.
The principle behind the kaarivalaisin involves a high voltage to initiate the arc, after which a lower
Despite their drawbacks, kaarivalaisimia played a crucial role in the early development of electrical illumination. Their
