Fényforrású

Fényforrású is a Hungarian adjective meaning having a light source or light-emitting. The word is formed from fény (light) and forrás (source) with the suffix -ú, and it is used primarily in technical and scientific language to describe objects, devices, or systems that emit light or rely on an explicit, built-in light source. The term helps distinguish such items from those that are merely illuminated by ambient light or by reflected light.

In practical use, fényforrású describes equipment and setups that generate illumination through an internal or integrated source. Examples include fényforrású lámpatestek (fixtures with their own light source), fényforrású optikai rendszerek (optical systems that incorporate a light source), and fényforrású mérőeszközök (instruments that include a light source). The concept is also employed in experimental contexts to emphasize the origin of photons used in a procedure, such as fényforrású gerjesztés (light-source excitation) or fényforrású megvilágítás (illumination by a light source).

The term is commonly found in fields like optics, instrumentation, and lighting technology. Its meaning may vary with context, but it generally points to the presence and use of a designated light source within the described item or process. Opposite terms include fényforrás nélküli or fénymentes, used to indicate absence of an integrated light source or reliance on external lighting.
