Fényvezérelt

Fényvezérelt is a Hungarian term that translates to "light-controlled" or "photo-controlled" in English. It refers to a system, device, or phenomenon where the behavior or operation is influenced or regulated by light. This can encompass a wide range of applications and scientific principles.

In optics and electronics, a fényvezérelt component might change its electrical resistance, conductivity, or other properties in response to varying light intensity. Photoconductive materials, for example, exhibit this characteristic. Such components are often used in light sensors, automatic lighting systems, and exposure meters.

The term can also describe processes in biology where light plays a regulatory role. For instance, photoperiodism in plants, where flowering or other developmental stages are triggered by the length of day or night, could be considered a form of fényvezérelt phenomenon. Similarly, certain biological responses in animals, like the regulation of circadian rhythms by light, fall under this broad definition.

In a more technical context, fényvezérelt systems might involve the use of light beams to trigger or steer a process, such as in some forms of laser machining or optical tweezers. The core concept remains the modulation or initiation of an action based on the presence, intensity, or wavelength of light. The specific manifestation of fényvezérelt depends heavily on the context in which it is applied.
