Sähkövalaistuksen
Sähkövalaistus refers to the use of electricity to produce light. This technology has revolutionized human life, enabling activities to extend beyond daylight hours and transforming homes, workplaces, and public spaces. The fundamental principle behind most modern sähkövalaistus involves passing an electric current through a medium or a component, causing it to emit light.
Different types of sähkövalaistus utilize distinct physical phenomena. Incandescent lamps, once dominant, generate light by heating
More recently, LED (Light Emitting Diode) technology has become increasingly prevalent. LEDs are semiconductor devices that
