Philips 35Watt BD17 Ceramalux High Pressure Sodium High Intensity Discharge HID Light Bulb
Sodium vapor lamps are some of the most efficient lamps in the world. They have an efficiency of up to 190 lumens per watt compared to an incandescent street lamp which has between 15 and 19.

A low-pressure sodium lamp is shown in Figure 6.3.9. Even though they emit a yellow light, a low-pressure sodium lamp should NOT be confused with a standard high-pressure sodium lamp, which is a high-intensity discharge lamp. Figure 6.3.9. Low-pressure sodium lamp. Low-pressure sodium lamps operate much like fluorescent lamps and require ballast.

High pressure sodium vapor (HPS) lights, similar to LPS lights, are a specific type of gas- discharge light (also known as a high intensity discharge, HID or arc light). The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp.
Sodium Vapour Lamp Working Principle
A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm . Two varieties of such lamps exist: low pressure and high pressure.

A gas-discharge lamp that uses sodium (Na) in an exciting condition to generate light at a 589 nm of characteristic wavelength is known as a sodium vapor lamp. These lamps were commercially designed first sodium lamps by Philips in the year 1932, Holland.
Shop HSE E27 50W Warm White Sodium Discharge Lamp HSE50SDW
When the sodium vapor lamp is turned on, it sends an electric discharge within the neon gas which generates sufficient heat to evaporate the solid sodium. In case, when the sodium vapor lamp is not operated, the sodium remains deposited on the side walls of the tube in solid condition.

High Pressure Sodium Discharge Lamp GES Mullingar Electrical
High-pressure sodium discharge lamps. The review article deals with the high-pressure sodium (HPS) discharge lamp, characterised by a sodium vapour pressure above 5 kPa and a power density of about 100 Wcm −3. In its short history - the sodium-resistant translucent alumina used as the discharge tube material was invented only in the late.
High Pressure Sodium Lamp Arizona Integrated Technology, Inc.
What is a High Pressure Sodium Lamp? A high-pressure sodium lamp is a specialized gas discharge lamp containing sodium metal vapor operating at high pressures that produces light by the excitation of sodium ions. They provide high luminous efficacy and long life, making them suitable for street lighting, floodlighting, etc.
Philips 250Watt ED28 Mercury Vapor Deluxe High Intensity Discharge HID Light Bulb140806 The
In order to get the electric discharge started, the lamp housing needs to contain a small amount of a starter gas, typically neon and/or argon, in addition to the sodium. The discharge can then be initiated in that gas, and the resulting temperature rise leads to evaporation of the sodium. It takes a couple of minutes until the lamp can reach.

Sodium gas discharge lamps can be distinguished in two main groups: low-pressure sodium lamps in which the gas pressure is very low (0.7 Pa or 7.10 −6 atm) and high-pressure sodium lamps in which the gas pressure is a factor 10,000-100,000 times higher (10-100 kPa); [ 2 - 4 ].

Working of Sodium Vapour Lamp. The lamp requires high voltage at the time of starting i.e. switching on, which is obtained from the high leakage transformer. The discharge takes place through the neon gas and is of pink colour. The gas is heated up and sodium is vaporised. A yellowish light is produced when sodium vapours also takes part.
