SODIUM LAMP Meaning and
Definition
-
A sodium lamp is a type of low-pressure discharge lamp that uses sodium vapor in order to emit light. It consists of a sealed glass envelope containing a small quantity of neon gas and a small amount of metallic sodium. When an electric current is passed through the lamp, it ionizes the neon gas and subsequently allows the sodium to vaporize. The vaporized sodium then emits a bright yellow or orange light when it is excited by the discharge.
Sodium lamps are widely used in various applications such as street lighting, industrial facilities, and sports arenas due to their high luminous efficiency and long lifespan. They are particularly known for their distinctive yellowish glow and are commonly referred to as "sodium vapor lamps" or "high-pressure sodium lamps". These lamps typically operate at high temperatures and require a ballast to regulate the electrical current. The ballast helps to start and maintain the discharge in the lamp by limiting the current flow.
One of the key advantages of sodium lamps is their energy efficiency. They convert a higher percentage of input energy into visible light, making them more economical than traditional incandescent or fluorescent lamps. Moreover, the yellowish light emitted by sodium lamps offers good color rendering for some applications, such as outdoor lighting. However, the color rendering may be inadequate for certain situations that require accurate color perception, such as in museums or retail settings.
In recent years, sodium lamps have faced competition from newer lighting technologies, such as LEDs, which are even more energy-efficient and offer superior color rendering. Nonetheless, sodium lamps continue to be used in many areas where their specific characteristics meet the requirements.

Etymology of SODIUM LAMP
The word sodium in sodium lamp comes from the element sodium, which is commonly used in the lamp's construction. The term sodium itself is derived from the Medieval Latin word sodanum, which originated from the Arabic term suda, meaning headache. This is likely due to the discovery of sodium carbonate, a compound used medicinally to relieve headaches. The combination of this historical association with the element's properties led to the name sodium.
