What is electric light mixture gas?

Electric light source mixture usually refers to various gas mixtures used in gas discharge light sources. The mixture of electric light source is an important part of gas discharge light source, which directly affects the performance and quality of the light source. When designing and manufacturing electric light sources, choosing the right gas mixture is crucial to achieving the desired optical characteristics and economic benefits.

A gas discharge light source is a light source that emits light between two electrodes placed in a gas. Because of its high luminous efficiency, this kind of light source is widely used in lighting, display technology and scientific experiments. According to the different pressure of filling gas in the lamp tube, the gas discharge light source can be divided into three categories: low pressure, high pressure and ultra-high pressure.

Here are some details about mixtures for electric light sources:

1. Composition and characteristics: The mixture of electric light sources is generally composed of two or more gases mixed in a specific proportion, and the common mixture components include argon (Ar), nitrogen (N2), Krypton gas (Kr), etc. The selection and mixing ratio of these gases is determined according to the desired spectral characteristics and discharge characteristics.

2. Application: Different gas mixtures are also different in the application of electric light sources, such as argon or a mixture of argon and other gases is often used in fluorescent lamps to improve starting performance and luminous efficiency; In metal halide lamps, a more complex gas mixture may be used to obtain better light color characteristics and luminous efficiency.

3. Industry standards: In order to ensure the quality and application effect of the mixture used for electric light sources, there are special industry standards to regulate such products. For example, China’s standard “Krypton/argon gas mixture for electric light sources” stipulates the technical requirements and test methods of the relevant mixture products.

4. Safety: Although the single gas in the mixture, such as argon and nitrogen, is colorless, odorless and non-toxic at room temperature and pressure, it is still necessary to pay attention to safety during use to avoid risks caused by equipment leakage or improper operation.
