High Pressure Sodium Vapour Lamp Ignitor

Neither mercury vapor nor standard metal halide fixtures need ignitors to strike an arc through the lamp. There is an ignitor built into the ballast which sends a pulse of high voltage energy through the arc tube. Only high pressure sodium and pulse start metal halide fixtures have ignitors.

High pressure sodium lights are used for illuminating large outdoor areas. 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. I must apologise fo. Sodium bulbs can last up to 20 000 hours.

The sodium vapor strikes an arc over 240 c. Low pressure and high pressure low 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. An ignitor is used when high pressure is necessary to strike an arc through certain materials and get the temperature up very quickly inside it. These types of lights are commonly found outside.

High pressure sodium lamp hps lamp. The lamp turns sky blue as the xenon lights. This pulse starts an arc through the xenon gas. The sodium is mixed with other impurities to create a.

A high pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high pressure sodium gas to produce the light. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. They emit bright yellow light.
