WHAT DOES SODIUM-VAPOUR LAMP MEAN IN ENGLISH?

Sodium-vapor lamp

A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light. There are two varieties of such lamps: low pressure and high pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor lighting such as street lamps. High-pressure sodium lamps have a broader spectrum of light than the low pressure, but still poorer color rendering than other types of lamps. Low-pressure sodium lamps only give monochromatic yellow light and so inhibit color vision at night. Because sodium-vapor lamps cause less light pollution than mercury-vapor lamps, many cities that have large astronomical observatories employ them.

Definition of sodium-vapour lamp in the English dictionary

The definition of sodium-vapour lamp in the dictionary is a type of electric lamp consisting of a glass tube containing neon and sodium vapour at low pressure through which an electric current is passed to give an orange light. They are used in street lighting.
