HochdruckNatriumlampen

Hochdrucknatriumlampen, often abbreviated as HSN lampen, are a type of high-intensity discharge (HID) lamp that produces light by passing an electric arc through vaporized sodium under high pressure. They are known for their high luminous efficacy and long lifespan, making them a popular choice for various lighting applications. The light produced by these lamps is characterized by a distinct yellow-orange hue.

The construction of a Hochdrucknatriumlampe involves a ceramic discharge tube, typically made of translucent aluminum oxide, which contains the sodium metal, mercury, and xenon gas. When an electric current is applied, the gas ionizes, and the mercury vaporizes. This initial arc heats the sodium, causing it to vaporize and emit light. The high pressure within the discharge tube contributes to a whiter light and a higher luminous efficacy compared to low-pressure sodium lamps.

These lamps require a ballast to regulate the current and voltage during operation. They also need a starter to initiate the arc. Once ignited, HSN lampen can take several minutes to reach their full brightness and color temperature. They are commonly used for street lighting, industrial areas, security lighting, and sports stadiums due to their efficiency and durability. Their spectral output, while not ideal for color rendering, is very efficient at producing visible light.
