When current passes between the electrodes it ionizes the neon and argon. Typically these lights are used on sides of industrial buildings and in some street lamps.
Wrg 4274 Sodium Vapor Fixture Wiring Diagram
Sodium vapour lamp wiring diagram. This is the information for how we connected the metal halide lamp and sodium vapour light to the circuit 230v there are many types of lights wiring. High pressure sodium lamp hps lamp the hps lamp is the most ubiquitous lamp for street lighting on the planet. Low pressure and high pressurelow pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. They generate light by sending an. Sodium vapour lamp connection hpsv lamp sodium lamp wiring diagram sodium vapour lamp connection sodium vapour lights are a type of gas discharge lamp. Sodium bulbs can last up to 20000 hours.
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. In 1959 the development of polycrystalline alumina pca opened a new path to introduce the high pressure sodium vapor lamp as this material is very rarely affected by high pressure and. The better color rendering comes with a bit of sacrifice it has less efficiency than the lps. High pressure sodium ballast wiring diagram sodium vapor lamp circuit diagram unique low pressure sodium vapour lamp perfect lamp efficacy efficiency. The lamp is an improvement over the lps lamp in that it has more acceptable color with the great efficiency of the sodium lamp.

At starting electric discharge is to be established through neon gas till sodium gas vapourized so at start for 10 15 min. Two varieties of such lamps exist. They emit bright yellow light. High pressure sodium lights are used for illuminating large outdoor areas. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. Sodium vapour lamp electric discharge lamp using ionized sodium used for street lighting and other illumination.
This is the main difficulty of producing high pressure sodium lamp. A low pressure sodium vapour lps lamp contains an inner discharge tube made of borosilicate glass that is fitted with metal electrodes and filled with neon and argon gas and a little metallic sodium. Discharge through lamp will be pink and then as sodium vaporizes it will turn to yellow. It is very difficult to get any material which is free from corrosion in presence of sodium vapor in high temperature and pressure.
