Low pressure sodium lamp is the best source of solar street lighting system: low pressure sodium lamp emission wavelength is monochromatic light and 589.6nm 589.0nm. The two yellow spectral line positions near the human eye is most sensitive wavelength is 555.0nm green spectral lines, not only has high luminous efficiency, and in the eyes of the world does not have a color, so see high resolution, good contrast for in road, overpass, tunnel and intersections high visibility and color requirements. Low pressure sodium lamp also has no glare. The luminescence efficiency is 200lm/W low pressure sodium lamp, electric light source is the highest light efficiency of a light source, the life is long.

Low pressure sodium lamp luminous efficiency of high luminous efficiency, short light effect. It is the luminous flux emitted from a light source and its electric power ratio, unit is lumens per watt (LM / W), is the evaluation of electric light source power efficiency the main technical parameters. The flux is refers to the size of light radiation per unit time, used to represent the lumen. The greater the luminous flux emitted by power source unit, low pressure sodium lamp is by means of low pressure sodium vapour discharge luminous electric light source in the glass shell coated with IR reflecting film is smaller attenuation and luminous efficiency highest electric light source. From the low pressure sodium lamp is monochromatic yellows and places for the color does not require, but the "fog" performed very well, especially for highway, road traffic, municipal roads, public round, garden lighting, can make people clearly see the color difference is small.

Low pressure sodium lamp is an alternative to high pressure mercury lamp to save electricity, a lamp, application is also expanding.
