High Pressure Sodium Lamps

HPS (High Pressure Sodium) lamps are a type of high-intensity discharge lamp known for their energy efficiency and high light output, producing a distinctive yellow-orange glow.

They are commonly used for outdoor area lighting like streetlights and for commercial growing, especially during the flowering and fruiting stages of plant growth, due to their intense, deep-penetrating light spectrum. Key features include a long lifespan, a ballast to regulate current, and a warm-up period to reach full brightness.

How they work

An electric current is passed between two electrodes at the ends of a ceramic arc tube.

The arc tube contains a mixture of mercury, metal salts, and sodium.

Xenon gas is used as a starter gas to help strike the arc.

As the arc is struck, the xenon and mercury are ionized and the arc tube heats up.

As the temperature and pressure increase, the sodium vaporizes and the characteristic yellow-orange light of the HPS lamp is produced.

The outer glass envelope insulates the arc tube and contains a vacuum or inert gas to help manage heat.

How they work

An electric arc is struck between two electrodes inside a quartz or ceramic arc tube.

The arc vaporizes mercury and other metal halides (compounds of metal and halogens like bromine or iodine).

The mixture of vaporized gas and metal halides creates a high-intensity, full-spectrum light when energized.

About Wire Wound Ballasts

Wire-wound ballasts, commonly referred to as magnetic or electromagnetic ballasts, are traditional lighting control devices designed to regulate the voltage and current supplied to discharge lamps, such as fluorescent tubes and High-Intensity Discharge (HID) lamps. They consist of copper wire wound around an iron core to create an inductor that restricts current flow, preventing lamps from drawing too much power and burning out.

Key Characteristics and Functions

Operating Principle: They use electromagnetic induction to manage current. When power is turned on, they provide a high-voltage surge to ignite the lamp, then limit the current to a steady, lower level once the lamp is running.

Components: They consist of a copper coil, an iron core, and often a capacitor.
