Comparison Between Sodium Vapor Lamp and Mercury Vapor Lamp

What is Sodium Vapor Lamp?

A gas-discharge lamp that uses sodium (Na) in an exciting condition to produce light at a 589 nm wavelength is known as a sodium vapor lamp. Philips introduced the first commercially available sodium lamps in 1932 in Holland....

Sodium Vapor Lamp Circuit

The sodium vapor lamp circuit diagram is shown in below. Here, the type of lamp uses in this circuit is a low-power sodium vapor lamp (LPSVL). The construction of this light is like a mercury vapor lamp. In this lamp configuration, two electrodes, E1 and E2, along with a capacitor (C), a choke (L), and a small step-down transformer (T) are connected in series with the lamp. The choke (L) is an inductor is Connected in series with a low-power sodium vapor lamp. It stabilizes the discharge in the same way that overload protection does. The transformer utilized in the above circuit is a step down transformer for reducing the voltage supply and settling the circular segment. The vapor lamp, choke, and transformer are all connected in series to heat the cathode electrode “E1” inside a G1 glass tube that contains sodium and a small amount of argon or neon gases. This G1 glass tube is set in a G2 evacuated external tube....

Working of Sodium Vapor Lamp

When the sodium vapor lamp is turned ON, it releases neon gas inside , which produces adequate intensity to dissipate the Na (sodium). A small transformer is utilized to warm the cathode fiber inside the release tube while the anode terminal is associated straight to the 230V AC supply all through a choke. In light of both the transformer and gag, the power factor (P.F) of the above circuit will turn exceptionally low, so a capacitor is used for correction purposes....

Comparison Between Sodium Vapor Lamp and Mercury Vapor Lamp

Sodium Vapor Lamp Mercury Vapor Lamp Sodium vapor lamp efficiency is around 100 lumens/watt. It produces between 35 and 65 lumens per watt of light. Sodium vapor lamp is a gas discharge lamp. Mercury vapor is likewise a gas discharge lamp This lamp uses sodium in an energized condition to emit light. This light purposes an electric arc segment with vaporized mercury to radiate light The light in this lamp is from the process of a atomic emission. The light in this lamp is from the process of fluorescence emission. It is used for street and other lighting. It is used to provide like streets, sports arenas, gyms, shops, and banks. Its life expectancy is around 18,000 hours. Its life expectancy is around 24,000 hours. Sodium vapor lamp wavelength is 589 nm Mercury vapor lamp wavelength is 254 nm...
