Due to the low color spectrum on high pressure sodium lights, the light emitted is limited to a warm deep yellow light. Lights & Lighting » Light Bulbs » Gas Discharge Lamps » Sodium Vapour Lamps. Features. Typical applications include street lighting, parking lot light- ing, building floodlighting and general area lighting. A high-pressure sodium street light in Toronto. In a high pressure sodium lamp, a compact arc tube contains a mixture of xenon, sodium and mercury. There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). Typically these lights are used on sides of industrial buildings and in some street lamps. A sodium vapor lamp is a lamp that uses sodium to create light. Price — Is on Sale % Show sale items only . These lamps are used for gen-eral lighting applications where high efficiency and long life are desired, but color is not critical. low pressure sodium vapour lamp This lamp was invented first in 1920 by ARTHUR H. COMPTON at Westinghouse, USA. Mercury vapor lamps are high-intensity discharge lamps that pre-date modern high-pressure sodium and metal halide lamps. High Pressure Sodium lamps deliver more lumens per watt over rated life than most other HID light sources available today. high pressure sodium ballast wiring diagram – A Beginner s Overview of Circuit Diagrams. Working principle of sodium vapour lamp . 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. High pressure sodium bulbs and metal halide bulbs emit different color spectrums of light. Categories Filter / Sort. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. Top brands include Osram, Philips and Venture Lighting. 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 bulbs ("lamps") are an old standby for lighting that's still used today in spite of so much talk of LED lights. SALE | Get up to 60% off. 13.2. The lamp produces a clarity of light that creates vivid color from objects illuminated by it. Low-pressure sodium lamps only give monochromatic yellow light … Light up your warehousing, sports halls, stadium, car parks and shops with bright, energy saving light today from RS. It is a gas-discharge lamp that uses sodium in an excited state to produce light. Total luminous flux — Apply Reset filters . They are also commonly found in an indoor garden setting. 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. Manufacturer of High Intensity Discharge Lamp - High Pressure Sodium Vapour Lamp (Tubular), Metal Halide Lamp (Single Ended), Metal Halite Lamp (Double Ended) and High Pressure Sodium Vapour Lamp (Elliptical) offered by Capart Industries Private Limited, Hyderabad, Telangana. E27 E40 GX12 PG12-1 RX7s-24. Two varieties of such lamps exist: low pressure and high pressure. We get many phone calls from business owners needing our assistance with fixing and/or replacing their high pressure sodium light bulbs for parking lot lights and street lights. Ballast for the lamp to provide a high starting voltage, lamp conduction. High pressure lamps have more components than low pressure and contain other substances such as mercury. We are provide a wide range of Sodium Vapour Lamp. This emission is quite close to the maximum luminous efficiency function at 555 nm and hence contributes effectively to the luminous efficacy. High Pressure Sodium lamp with clear tubular outer bulb. This test is used to determine if an item can be managed as hazardous 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-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. There are high-pressure sodium lamps (HPS), and low-pressure sodium lamps (LPS), but they function in a similar fashion. A final advantage is that in the case of a momentary power supply interruption, the lamp will restrike as soon as the power is restored and no cooling down period is required. 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. How Sodium Vapour Lamps Work! 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. A metal halide bulb produces about 65-110 lumens of light per watt while a high pressure sodium bulb produces about … 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. Clear tubular outer bulb. 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. Filter. While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. When a high pressure sodium lamp is to be disposed, it is subject to the current EPA Toxicity Characteristic Leaching Procedure (TCLP) disposal criteria. 1 Citations; 2.8k Downloads; Abstract. Sodium Vapour Lamps. Shop high pressure sodium vapour lamps now! High pressure sodium lights are used for illuminating large outdoor areas. 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. Best Uses for High Pressure Sodium. The mercury vapor raises the gas pressure and operating voltage, and the sodium vapor produces light when … High luminous efficacy.
