Sodium-vapor lamp - Wikipedia
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. Two varieties of such lamps exist: low pressure and high pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor ...

低压钠灯是利用低压钠蒸气放电发光的电光源，在它的玻璃外壳内涂以红外线反射膜，是光衰较小和发光效率最高的电光源。 低压钠灯发出的是单色黄光，用于对光色没有要求的场所，但它的“透雾性”表现得非常出色，特别适合于高速公路、交通道路、市政道路、公园、庭院照明，能使人清晰地看到色差比较小的物体。 低压钠灯也是替代高压汞灯节约用电的一种高效灯种，应用场所也在不断扩大。 低钠灯sodium，lamp利用钠蒸气放电产生可见光的 电光源。 钠灯又分低压钠灯和 …
The Sodium Lamp - How it works and history - Edison Tech Center
There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). These lamps are mostly used for street lighting as well as industrial uses. The lamp works by creating an electric arc through vaporized sodium metal. Other materials and gases are used to help start the lamp or control its color.
