fényforrásokra

Fényforrásokra refers to light sources in Hungarian. A light source is any object that produces visible electromagnetic radiation. These sources can be broadly categorized into natural and artificial types. Natural light sources include celestial bodies like the Sun and stars, which emit light through nuclear fusion. Other natural sources include phenomena like lightning and bioluminescence, which is the emission of light by living organisms.

Artificial light sources are human-made and have revolutionized daily life, particularly since the invention of the incandescent light bulb. These include technologies like fluorescent lamps, which use a gas discharge to produce UV light that excites a phosphor coating, and light-emitting diodes (LEDs), which are semiconductor devices that emit light when an electric current passes through them. Lasers are another type of artificial light source that produce a highly concentrated and coherent beam of light. The study of light sources is fundamental to fields such as physics, optics, and illumination engineering, with ongoing research focused on developing more efficient, sustainable, and versatile lighting technologies.
