2.2 High Pressure Sodium (HPS) High Pressure Sodium lamps have an efficacy of 90-140 Lumens Per Watt, very long lamp life at 10,000 - 40,000 hours and a short warm up time of 3-4 minutes. Since the high-pressure sodium arc is extremely chemically reactive, the arc tube is typically made of translucent aluminum oxide. The starter circuit turns on a high pressure sodium lamp with high voltage narrow pulse width start-up signals. They are used for things such as security lighting.

In combination with initial light output, mean light output may be used to estimate lamp lumen depreciation. High-pressure sodium lamps are quite efficient — about 100 lumens per watt, when measured for photopic lighting conditions. High pressure sodium vapor arc discharge lamps are commonly used for street lighting. In a high pressure sodium lamp, a compact arc tube contains a mixture of xenon, sodium and mercury. This requirement is met by operating the lamp for a stray field – up -tapped- autotransformer with an open circuit secondary voltage of 470 to 480 Volts. A ballast circuit for driving a sodium vapor lamp includes a ballast transformer having a primary winding connected to a constant current power source.

There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS).These lamps are mostly used for street lighting as well as industrial uses. Hey, welcome to SL Engineering Academy. The Mercury lamp was the first kind of metal vapour light source that was mass When the lamp is first energised the full open circuit voltage is applied across. Such a lamp usually consists of two bulbs — an arc-tube containing the electric discharge and an outer bulb which protects the arc-tube from changes in temperature. The sodium vapour lamp is only suitable for a alternating current, the, therefore, required chock control.

Low pressure sodium lamp is a kind of low pressure sodium vapor discharge tube, inner tube with special anti sodium glass blown, and can radiate 5890A, 5896A sodium line, can be used as a monochromatic light source optical polarimeter, refractometer, polarization instrument in. Department of Electrical & Communication Engineering Conclusion From this Experiment, we knew how to build diagram to compare the performances of two lamps .We compare the performances between a high pressure sodium vapor lamp and a high pressure mercury vapor lamp.So the concluded that HPSV has higher overall performance compared to HPMV, and a higher efficacy.Fainally, HPSV and HPMV lamps … The gaseous discharge type of lamp is either low or high pressure.Low-pressure gaseous discharge sources are the fluorescent and low-pressure sodium lamps… Fig: 1 . Suggest where this type of lamp may be used, and indicate how the manufacturers can improve its colour-rendering properties. Most magnetic HID ballasts are multi-tap, meaning they can be connected to several different voltages. Which position MB type high pressure mercury vapour lamps are operated? b Low pressure sodium vapour lamp circuit c High pressure sodium vapour lamp from ELECTRONICS 101 at College of Engineering, Pune Figure S36 - Linear Self-Starting Low Pressure Sodium Lamp It is interesting to note that whereas most low pressure sodium lamps have been developed to deliver the maximum luminous efficacy, these early linear sources appear to have been optimised instead for generating the maximum luminous flux with a high surface luminance. Subject: IEN (17639) Electrical Engineering Dept. This is a free online engineering learning page for students, engineers and like-minded people. 43. The voltage necessary to ignite the arc in the gases in a sodium lamp is derived from a starter circuit connected across a ballast transformer. Sodium vapor lamps are similar to the mercury vapor lamps, as they come in both low pressure and high pressure versions. sodium vapour lamp circuit Can u help me to design a circuit for a sodium low pressure lamp? H3. Note that, due to the HPS ballast’s electronic starting circuit, warm-up and restrike periods are much shorter than those of metal halide lamps. H2. Sodium Lamps were first produced commercially by Philips in Holland in 1932. They are also commonly found in an indoor garden setting. SL Engineering Academy. A schematic diagram of mercury lamp is shown below. A secondary winding of the transformer is connected across the lamp.
