Low pressure sodium lamp advantages and disadvantages.

Average 2000k known for their warm yellow glow. Low pressure sodium lamps common uses and advantages low pressure sodium lamps are used in outdoor lighting of some parking areas and bridge underpasses. The very yellow color does not attract insects but it distorts colors. The low pressure sodium lamp the lps lamp was the first sodium lamp to be developed.

In a low pressure sodium vapour lamp argon or neon gas is first heated up to emit a slight red or purple glow. High pressure sodium area lights are most commonly seen on the road and in parking lots. Sodium vapour lamp is a gas discharging lamp which uses sodium in an excited state to produce light near 589 nm wavelength. Lps light provides essentially no color rendition so is inappropriate for any use where 1 color perception is important and 2 lps will be the only light source illuminating the area.

Designing with lps see also lps costs low pressure sodium like all lighting types has its own pecularities advantages and disadvantages some of these are discussed in these links. The heat from this warms sodium metal in the light to the point of vaporizing which. It is mostly used in europe since it did not advantages. The colour rendition properties are not comparable to the other lamps the white son lamp has a ra value of 80 while the sox has a ra of just 20 which is way below that of an incandescent ra 100.

These sodium atoms are liberated from the planet s surface by photon stimulated desorption ion sputtering and micrometeoroid impact vaporization ejected at energies capable of escaping mercury s. These lamps are available in low pressure and high pressure varieties. What are the disadvantages of sodium vapour lamps. Disconcerting color rendering cri that can inhibit vision at night and create darker shadows.
