Fénykibocsátású

Fénykibocsátású is a Hungarian term that translates to "light-emitting" in English. It describes the property of a substance or device that produces light. This can occur through various physical processes.

One common form of light emission is incandescence, where light is produced by heating an object to a high temperature. Traditional incandescent light bulbs work on this principle. Another is electroluminescence, where light is generated when an electric current passes through a material. This is the principle behind light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs).

Fluorescence is another mechanism, where a material absorbs light at one wavelength and re-emits it at a longer wavelength. This is seen in fluorescent lamps and glow-in-the-dark materials. Phosphorescence is similar to fluorescence but the re-emission of light is delayed, causing the material to continue glowing after the excitation source is removed. Bioluminescence is light produced by living organisms through chemical reactions.

The term "fénykibocsátású" can be applied to a wide range of objects and phenomena, from natural sources like stars and fireflies to artificial sources like displays and lighting fixtures. Understanding the specific mechanism of light emission is crucial for developing and utilizing these technologies effectively.
