Another advantage when using the CMH lamp, is the lower wattage – it is only 315 watts, compared to a metal halide lamp which is often 600-1000 watts. low pressure sodium lamp advantages and disadvantages. Although LED and High-Pressure Sodium are both popular options for area lights and outdoor fixtures, let's explore the difference between the two and why you should consider LED lighting. 1) Tabulate advantages, disadvantages, sensitivity, and life expectancy of incandescent bulb, sodium vapour lamp, Halogen lamp… They are 3 to 5 times more efficient than incandescent lamps. Sodium vapour lamp is a gas discharging lamp which uses sodium in an excited state to produce light near 589 nm wavelength. Their applications extend across a range of domestic and commercial areas, and are affected by the type of gas being used. Precaution : Care should be taken in handling these lamps, for if inner tube is broken and sodium comes in contact with moisture , fire will result. What are the advantages of Sodium Vapour lamps? The newer LPS lamps contain less mercury than before, but this has effected performance … It consists of 2 electrodes made up of an alloy of tungsten which is placed together in a medium containing mercury vapor and 25-50 torr of pure argon gas. Required fields are marked *. They are more energy efficient than incandescent lamps and have a much longer life. The disadvantage is they do not flatter the human skin color thereby making them not an ideal technology for indoor applications. Sodium is hazardous and can catch fire in contact of air.

In theory, these bulbs can last a full year before needing replacement. Add your answer and earn points. Where are Sodium vapour lamps used? The arc tube consists of frame and is highly pressured with sodium for better efficiency. Although the high voltage lamps described previously brought numerous advantages over the original low voltage developments, a notable disadvantage of both types in the early years was the complexity of the electrical control gear required to operate them. High Pressure Sodium Lamp: Working Principle . Their applications extend across a range of domestic and commercial areas, and are affected by the type of gas being used. A Ballast component is similar to a transformer with high leakage reactance. The major disadvantage is that it still has a bad color when compared to a metal halide lamp. In addition to the simple ballasting task to control discharge current, means also had to be provided to ignite the discharge. Info on Architecture, Interiors and House Construction In India. “Low-pressure sodium lighting is a monochromatic source and is often rejected for its deficiency in supporting color. Life : Normal average life of sodium vapour lamps is 2500 hrs. Colour rendering: 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).
