As we all know, incandescent lamp is an important invention of Edison, this important invention makes human beings bid farewell to darkness, ushered in the light, slowly energy-saving lamps appeared, after people's research chicken coop special lamp came into being, the following for you to introduce the light principle of chicken coop special lamp.
The poles of the chicken coop special lamp are ordinary tungsten wire. After the tungsten filament is energized and heated, it can emit electrons. Add a relatively high voltage on both sides of the lamp to form an electric field, and these electrons will be accelerated in the lamp to form a flow of electrons with a certain speed and energy. The lamp is pumped into a vacuum and filled with mercury, which is what we call mercury.
When the lamp tube of the chicken coop special lamp is energized and heated, the mercury evaporates from the liquid state to the gaseous state. Mercury atoms that form a free state. The electrons in the electron flow hit the mercury atom at a certain speed, causing the mercury atom to be excited and become an electric ion in the excited state. Known as a step, the excited state of mercury spontaneously falls back to its original state after a short period of time, while releasing ultraviolet light, which cannot be used for lighting. So we coated some fluorescent substances on the inner wall of the lamp, and under the bombardment of ultraviolet light, the fluorescent substances can emit more natural light after being stimulated.
