Sodium Vapor Lamp Types
There are two kinds of sodium vapor lamp accessible in the market are as follows:
- LPS fume light (Low-Pressure Sodium Vapor Lamp)
- HPS vapor Lamp (High- Pressure Sodium Vapor Lamp).
Low-Pressure Sodium Vapor Lamp
Low-Pressure Sodium Vapor Lamp In 1920, Arthur H. Compton at Westinghouse developed the first low-pressure sodium vapor lamp (LPSV). The primary created sodium light is a LPS light or low-pressure sodium light. The distinctive color of this lamp, which is a monochromatic yellow, makes it easy to identify it. It was utilized in Europe since it didn’t used in different industrial areas due to its poor efficiency in producing light.

Working of Low-Pressure Sodium Vapor Lamp
LPS Lamp is an extremely proficient light Worldwide because of its few Advantages. The light produced by this lamp is at a wavelength most responsive to the human eye, making it highly visible. In reality, an incandescent lamp emits light across a wide range of frequencies, from infrared (IR) to ultraviolet (UV). The low-pressure sodium lamp is also known as a SOX lamp.
The LPS fume light is for the most part utilized for open air lighting in Europe. At the point when the light starts, it initially makes a red shine due to the neon gas, however neon gas lights just at less temperature. The sodium begins to vaporize at a higher temperature, transforming into a pure, monochromatic yellow light.
High- Pressure Sodium Vapor Lamp
The principal HPSV light was developed and Introduced into the market in Schenectady, New York and Nela Park, Ohio in the year 1964. The HPSV light is the most often utilized in road lighting. The improvement of the LPS light is the HPS light but it has less proficiency with respect to LPS. The HPS light utilizes a restricted arc tube supported by a frame within a bulb.

Working of High- Pressure Sodium Vapor Lamp
The circular segment tube is designed with aluminum oxide ceramic since it Withstands the acidic impacts of soluble bases like Na (sodium). The curve tube uses high tension for higher proficiency. In this cylinder, xenon, sodium, and mercury are typically utilized.
The most common method to activate the light is through a pulse start. An ignitor inside the ballast sends a high-voltage signal through the arc tube, activating an arc with the xenon gas. As a result, the light turns blue, similar to xenon lights.
After that, the mercury (Hg) is heated by the arc, and its vapor gives the lamp a bluish color. The light gets heat and the sodium is the last material to Vaporize. White light is produced when sodium (Na) vapor meets an arc at temperatures above 240 degrees Celsius. The mercury helps to enhance and refine the yellow hue of the sodium light, contributing to its ideal shade.
Sodium Vapor Lamps
A light where an electric discharge happens all through a metallic vapor is known as a vapor lamp. These lights are accessible in two types sodium vapor lamps and mercury vapor lamps which emit various shades of light like thick blue and yellow respectively. These lights are highly efficient and provide concentrated illumination, making them ideal for open spaces and for lighting up large distances.
A vapor lamp typically includes a double tube where vapor is enclosed within the tube while the outside tube is empty with air, so it retains risky hazardous UV radiation.
