In the evening, I went for a walk in the square with my mom and dad. When walking, I found that the neon lights along the way emitted all kinds of lights, some red, some blue, some light green, some yellow... I thought: Why do neon lights emit these different colors of light? The general lights are white. Could it be that a layer of plastic paper of different colors was breaded outside the lampshade? Or is it a layer of paint of different colors on the lamp? Puzzled, I asked my mother, "Mom, why does this neon light emit these colorful lights?" Was it painted on the lamp? Or is there a layer of plastic paper wrapped in the lampshade? Mom replied: "Because there is a rare gas in the neon lights, what kind of gas it is, I don't know exactly, go home and check the information yourself!" "After returning home, I checked the "Three Hundred Questions on Natural Knowledge of the Ying ZhiHui" and learned that it turned out that neon lights were emitted through the action of gas discharge. After powering up, it emits light under the excitation of the electric field. Because the inert gases filled with neon lights are different, the color of the glow emitted is also different.
