Low Pressure Sodium Lamp Advantages And Disadvantages

The low pressure sodium lamp the lps lamp was the first sodium lamp to be developed.

Low pressure sodium lamp advantages and disadvantages.

What are the disadvantages of sodium vapour lamps. 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. The very yellow color does not attract insects but it distorts colors. Average 2000k known for their warm yellow glow.

Powerful lamp. Low pressure sodium light has a number of very unique properties arising from its spectral output many of which make it technically the most suitable light source for road lighting and these are covered in detail on the next page in. 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. The heat from this warms sodium metal in the light to the point of vaporizing which.

Low pressure sodium lamps common uses and advantages low pressure sodium lamps are used in outdoor lighting of some parking areas and bridge underpasses. 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. Sodium vapour lamp is a gas discharging lamp which uses sodium in an excited state to produce light near 589 nm wavelength. It is mostly used in europe since it did not advantages.

Disconcerting color rendering cri that can inhibit vision at night and create darker shadows. 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. High pressure sodium area lights are most commonly seen on the road and in parking lots. It is known by its signature monochromatic yellow color.
