High Pressure Sodium Vapour Lamp Ignitor

This pulse starts an arc through the xenon gas.

High pressure sodium vapour lamp ignitor.

The sodium is mixed with other impurities to create a. High pressure sodium lights are used for illuminating large outdoor areas. There is an ignitor built into the ballast which sends a pulse of high voltage energy through the arc tube. The lamp turns sky blue as the xenon lights.

They are also commonly found in an indoor garden setting. 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. A high pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high pressure sodium gas to produce the light. High pressure sodium lamp hps lamp.

Only high pressure sodium and pulse start metal halide fixtures have ignitors. They are used for things such as security lighting. Typically these lights are used on sides of industrial buildings and in some street lamps. Sodium bulbs can last up to 20 000 hours.

These types of lights are commonly found outside. This evenings experimentation consists of attempting to start a high pressure sodium hps lamp with a microwave oven transformer at 2kv. 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. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out.

Neither mercury vapor nor standard metal halide fixtures need ignitors to strike an arc through the lamp. 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. Two varieties of such lamps exist.
