Two varieties of such lamps exist: low pressure and high pressure. Best Uses for High Pressure Sodium. This phosphor technology offers better color rendition than the more efficient, high or low-pressure sodium vapor lamps, but still falls short of metal halide and ceramic metal halide sources. A high pressure sodium bulb produces light that is reddish-yellow, while metal halide bulbs produce a much more balanced white light that has more of the visual spectrum. Scientists have long been familiar with fact high luminous efficiency could be obtained by the use of sodium resistant glass, the sodium vapour lamp has now reached the practical stage. The xenon gas which is easily ionized, facilitates striking the arc when voltage is applied across the electrodes. Benefits. Ballast for the lamp to provide a high starting voltage, lamp conduction.

The mercury vapor raises the gas pressure and operating voltage, and the sodium vapor produces light when … First Online: 25 February 2017. The RS range of HID lamps includes metal halide and ceramic metal halide (including shatter resistant), high pressure sodium (SON) and low pressure, sodium (SOX) and mercury vapour. 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. Accordingly, how does a low pressure sodium lamp work? High pressure sodium ballasts for lamps provide stable current use of the inductive reactance of the ballast, and other pipe lit work. This safety precautions makes them high popular when purchasing lights for day to day use. A high-pressure sodium-vapor lamp. 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. Total luminous flux — Apply Reset filters . There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). Typical applications include street lighting, parking lot light- ing, building floodlighting and general area lighting. While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. A typical high pressure sodium lamp will last longer than a metal halide lamp of similar wattage. However, the first low-pressure lamps were sold commercially in the United States in after John Cooper Hewitt innovated the lamp's color spectrum from blue-green to white. SALE | Get up to 60% off. Most high pressure sodium and all other light sources employed in street lighting contain mercury and special restrictions apply to the disposal of used lamps. This wavelength corresponds to yellow light. The striking feature of sodium-vapor lamps is their radiation dominated by the emission of two resonance lines at 589/590 nm. SON-T is a cost-efficient and reliable solution in High Pressure Sodium. Mercury vapor lamps are high-intensity discharge lamps that pre-date modern high-pressure sodium and metal halide lamps. The use of a counter electromotive force of the ballast, with Lenz's law explanation is that acts in the moments before the other pipe lighting. Outdoor sodium lights are either low-pressure or high-pressure lighting to illuminate large areas with bright light. Two varieties of such lamps exist: low pressure and high pressure. High Pressure Sodium Ballast (ANSI Code S54) and HPS FIXTURE REQUIRED. Top brands include Osram, Philips and Venture Lighting. Applications. A high-pressure sodium ballast is responsible for regulating the pressure in light fixtures that use high-pressure sodium gas to produce the light. When one of our licensed electricians meets on site and goes over everything, one of the options we always recommend, depending on the client’s needs, is retrofitting the old high pressure sodium bulbs with … Categories Filter / Sort. In a high pressure sodium lamp, a compact arc tube contains a mixture of xenon, sodium and mercury. Reference work entry. Delivery update. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. High-pressure sodium-vapour (HPS) lamps have an inner discharge tube made of translucent alumina that can withstand the corrosive effects of a mixture of mercury and sodium under greater pressure and higher temperature. We are provide a wide range of Sodium Vapour Lamp. A very first appearance at a circuit diagram could be confusing, however if you could review a subway map, you can check out schematics. high pressure sodium ballast wiring diagram – A Beginner s Overview of Circuit Diagrams. Sodium bulbs can last up to 20,000 hours. Light up your warehousing, sports halls, stadium, car parks and shops with bright, energy saving light today from RS. When a high pressure sodium lamp is to be disposed, it is subject to the current EPA Toxicity Characteristic Leaching Procedure (TCLP) disposal criteria. It is a gas-discharge lamp that uses sodium in an excited state to produce light. A 250 watt high pressure sodium lamp can last from 12,000 to 24,000 hours. Working principle of sodium vapour lamp . Robust construction is vibration- and shock-resistant leading to a reliable life. These types of lights are commonly found outside. The excited electrons emit light around a wavelength of 590 nanometers. High pressure lamps have more components than low pressure and contain other substances such as mercury. They emit bright yellow light. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. 13.2. Mercury vapor technology was developed throughout the s in England and Germany. Apply Reset filters . High pressure sodium lights are used for illuminating large outdoor areas. While many applications are ideal for Mercury vapor lamps, they are being challenged by the higher efficiency and better color balance of metal halide and ceramic metal halide lamps, and LED … High luminous efficacy. event a lamp is broken. Some bulbs also briefly produce a pure to bluish white light in between if the mercury achieves its high pressure arc discharge characteristic before the sodium is completely warmed. High-pressure sodium (HPS) lamps are smaller and contain additional elements such as mercury, and produce a dark pink glow when first struck, and an intense pinkish orange light when warmed. Filter. Road and residential lighting. Before we begin, the terms bulb and lamp are used interchangeably when living in this bulba-verse. High Pressure Sodium lamp with clear tubular outer bulb. How Sodium Vapour Lamps Work! SON lamps (sodium vapour lamp) is a gas discharge lamp that uses sodium to produce light via wavelengths. Due to the low color spectrum on high pressure sodium lights, the light emitted is limited to a warm deep yellow light. E27 E40 GX12 PG12-1 RX7s-24. The lamp produces a clarity of light that creates vivid color from objects illuminated by it. Base type. High pressure sodium bulbs ("lamps") are an old standby for lighting that's still used today in spite of so much talk of LED lights. Author: Technical Editor Category: Electrical Articles 11 May 18. These lamps are used for gen-eral lighting applications where high efficiency and long life are desired, but color is not critical. It can come in a high pressure or low pressure format. High Pressure Sodium lamps deliver more lumens per watt over rated life than most other HID light sources available today. Sodium Vapour Lamps. There are high-pressure sodium lamps (HPS), and low-pressure sodium lamps (LPS), but they function in a similar fashion. A high-pressure sodium street light in Toronto. 1 Citations; 2.8k Downloads; Abstract. High pressure sodium bulbs and metal halide bulbs emit different color spectrums of light. There are two types that exist (low pressure and high pressure), the difference being low pressure starts to ignite a lot slower than high-pressure SON lamps and goes through a phase of looking pink through to orange in colour. This causes the valence electron of the sodium atoms to excite to higher energy levels. There is an electric discharge when passing electricity through sodium vapors at high or low pressure. The heat generated by the arc then vaporizes the mercury and sodium. This test is used to determine if an item can be managed as hazardous low pressure sodium vapour lamp This lamp was invented first in 1920 by ARTHUR H. COMPTON at Westinghouse, USA. Lights & Lighting » Light Bulbs » Gas Discharge Lamps » Sodium Vapour Lamps. Low-pressure sodium lamps only give monochromatic yellow light … Typically these lights are used on sides of industrial buildings and in some street lamps.
