钠灯 Sodium-vapor lamp

(重定向自Sodium light)

钠灯,是指以金属钠蒸气为工作物质的照明装置,是气体放电灯的一种。钠灯的灯管内也会充填汞和稀有气体,但实际上起作用的是钠蒸气。钠被电离、激发后会发射出589nm的黄色光线,这些光线直接用于照明,而不是像荧光灯那样激发荧光物质发出白色的可见光。

Sodium-vapor lamp 钠灯

(重定向自Sodium light)
A sodium vapor lamp
Spectrum of a low-pressure sodium lamp. The intense yellow band is the atomic sodium D-line emission, comprising about 90% of the visible light emission for this lamp type.
High-pressure sodium lamp in operation
Spectrum of high-pressure sodium lamp. The yellow-red band on the left is the atomic sodium D-line emission; the turquoise line is a sodium line that is otherwise quite weak in a low pressure discharge, but becomes intense in a high-pressure discharge. Most of the other green, blue and violet lines arise from mercury.

A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light. There are two varieties of such lamps: 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. High-pressure sodium lamps have a broader spectrum of light than the low-pressure lamps, but still poorer color rendering than other types of lamps. Low-pressure sodium lamps only give monochromatic yellow light and so inhibit color vision at night.
