Noble gases are the general name of helium, neon, argon, krypton, xenon and radon. They are all colorless and odorless gases. They are often used in high-end fields such as medical treatment, scientific research, industry and aerospace. But one of the most important applications of noble gases is electric light sources. The colorful electronic billboards along the streets, the dazzling neon lights, and the night lights along the river make the buildings and decorations of modern cities colorful, flowery and gorgeous. All this is due to the electric light source gas! So what are the electric light source gas varieties? What is electric illuminant breed divisional? Which gases can be electric light source gases?

Before understanding the variety of electric light source gas, let's first understand why gas can be luminous as an electric light source! A gas is not a conductor in its normal state. When gas atoms are hit by electrons with a certain amount of energy, they are excited and ionized and emit light. When the discharge current is very small, the discharge is in the glow discharge stage; When the discharge current increases to a certain extent, the gas discharge shows low voltage and large current discharge, which is the arc discharge. The gas of electric illuminant can give off light, but the gas that can give off light is electric illuminant gas not necessarily!

Which kinds of electric light source gas can be divided into? We can classify gas discharge sources into three categories.

Low voltage discharge light source, high voltage discharge light source and ultra high voltage discharge light source.

There are two types of low pressure discharge light sources: glow and arc discharge light sources.

High voltage discharge light source: high voltage gas discharge lamp operation current can be larger, is a large current operation, so the lamp power can do larger. It does not need to be preheated to start, can be equipped with the appropriate trigger directly started. Gaoyou Tenghua Gas Equipment has learned that the high-pressure gas discharge lamp cannot be restarted and ignited immediately after the lamp is lit and extinguished. It needs a period of time to restart after the lamp cools down.

Ultra high pressure discharge light source: the light source has ultra high pressure xenon lamp, ultra high pressure mercury lamp and so on. Small luminous body, approximate high brightness point light source, easy to control light.
