Fénytartó
Fénytartó is a Hungarian term that translates to "light retainer" or "light holder." It does not refer to a specific, universally recognized object or concept in science or technology. Instead, it is a descriptive phrase that could be applied to various items designed to hold or contain light sources. Examples might include a lampshade, a chandelier fixture, a flashlight casing, or even a specialized container for bioluminescent organisms. The specific meaning of fénytartó would be entirely dependent on the context in which it is used. Without further context, it's a general descriptor rather than a technical term. Its usage is likely to be found in everyday language or in more specific technical descriptions where the function of holding light is paramount.
