sodium vapour lamp advantages disadvantages

Several slides from my presentation are enclosed. Thanks Dr. Zhi Jiang . At starting, electric discharge is to be established through neon gas till sodium gas vapourized , so at start for 10-15 min. Metal halide lamps are used where higher illumination levels are required. According to the American Heart Association (AHA), the recommended amount of sodium for everyone is 1500-2300 mg per day, but a majority of people consume more than this amount every day. advantages of sodium vapour lamps in green buildings: Efficiency: Sodium Vapour Lamps are very efficient, turning one watt of power into a whopping 200lumens! Jul 31, 2017. ChemInform Abstract: β-Na3Hg: A Solid with a Quasi-Fluid Sodium Substructure in the Temperature Range 36 to 60 °C. A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm.. Two varieties of such lamps exist: 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, where they are widely used. The main advantage of HPS lamp over LPS lamp is that former emits more acceptable color. No warm-up period – LED’s light instantly – in nanoseconds Keeps Your Blood Pressure In Check. I am a beginners in this field. © 2008-2020 ResearchGate GmbH. But I am able to run this site only because of the ads. Thanks. Dear Dr. Fernandez-Garcia, thanks for your valuable answer. To help you in deciding the suitability of using Sodium Vapour lamps in your home, as an Architect, I have listed their advantages, disadvantages and usage under the following headings: What are the advantages of Sodium Vapour lamps? The lamps produce a crisp white light and offer a goo… what are the disadvantages of sodium vapour lamps? The development of fluorescent lamps during the 1890s and 1900s and their subsequent commercialization beginning 1920s have led to direct competition against another type of electric lamp: the incandescent lamp. Life range between 6000 hours to 15000 hours. Join ResearchGate to find the people and research you need to help your work. An Ignitor which consists of three port… High Pressure Sodium Lamp: Working Principle Advantages: - Good efficiency lamps after s have a high lumen per watt rating - Color rendering is better than that of high pressure sodium street lights - Some lamps last far longer than the hour mark, sometimes 40 years. Light Colour: The monochromatic deep yellow wavelength light produced by the sodium vapour lamp is the ‘photopic’ range- in which humans see best. Better efficiency, life and size are few of the advantages of HPS Lamp over LPS Lamp. 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 light driven water oxidation/reduction is one of the main project in our group. Sodium Vapour Lamp July 5, 2017. I am interested to know which of these lamp is best suited for the photocatalytic decomposition of water either by UV light or by Visible light. Can anyone suggest a suitable lamp for photo-catalytic degradation. Counting the advantages, Discharge lamps can be highly effective at maintaining luminosity for an extended period of time. Low pressure sodium lamps are used in outdoor lighting of some parking areas and bridge underpasses. You may wish to specify you experiment in order to check pro and cons. Just wondering how we calculate the intensity. What are the advantages of LEDs over Sodium Vapour lamps in street lighting? Advantages of metal halide lamps: Good luminous efficiency. This results in a warmer color appearance and higher color rendering than standard mercury lamps. Your email address will not be published. So I will be obliged if you turn off your ad blocker. Info on Architecture, Interiors and House Construction In India. Your email address will not be published. What are the disadvantages of Sodium Vapour lamps? Mercury. Read more here: If you found this post useful, I would really love it if you pin it or share it. Below is a list of advantages and disadvantages of sodium. You should try by using LEDs. What do you use? High pressure sodium lamp will flash with white and gold when using. To help you in deciding the suitability of using Sodium Vapour lamps in your home. (adsbygoogle = window.adsbygoogle || []).push({}); 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). The biggest differences between LED and High-Pressure Sodium lights are color temperature and CRI. Which lamp is suitable for photocatalytic degradation? It consists of 4 connecting ports like “Com, 240 V, 200 V, IGN” 2. Sodium. Effective in rainy and foggy season. Disposal: The Sodium Vapour Lamps contain mercury like all discharge lamps and need to be disposed carefully. Recently I gave an oral presentation on an international meeting. However, they find continued patronage among environmentally sensitive users, due to their efficiency and long life. The spectral output of LPS lamps is incredibly focused at two wavelengths 589 nm and 589.6 nm. This blog showcases in detail the working of High-Pressure Sodium Vapour Lamp. The first priority is reproducibility of the values in other labs. What is the best way to learn it? Rugged – LED’s are also called “Solid State Lighting (SSL) as they are made of solid material with no filament or tube or bulb to break. There are various types of HID lamp, as follows. What is the best way to learn DFT (Density Functional Theory) for beginners?? What are the disadvantages of Sodium Vapour lamps? HPS grow lights are very useful because they mimic sun rays. Where to get the Elsevier Journal word Template ? For example, a 400-watt high pressure sodium lamp produces 50,000 initial lumens. (adsbygoogle = window.adsbygoogle || []).push({}); Efficiency: Sodium Vapour Lamps are very efficient, turning one watt of power into a whopping 200 lumens! Can anyone share the link or the reference which have a detail discussion about the different lamps and LEDs used and the wavelength range they cover ? Photocatalysis , light. Thank you! The LPS lamp is also called a SOX lamp (SO for sodium) Advantages: - Very efficient lamp - Powerful lamp for use of large areas - Despite a warm up time of 5-10 minutes it restarts immediately if there is a brownout - Lumen output does not drop with age (such as in LEDs or incandescents) Disadvantages: Metal Halide lamps last from 7,500 to 20,000 hours and are used in sports stadiums and car parks. May you suggest a VIS- light source for measuring photocatalytic activity? 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. 3. How can I calculate the UV dose, in J/m2? These indoor settings include warehouse and shipping areas and some manufacturing areas.
