You are now visiting the Philips lighting website. In a high pressure sodium lamp, a compact arc tube contains a mixture of xenon, sodium and mercury. Increasing arc tube pressure improves the colour appearance of reds, blues, and greens. 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. Since the early 1970s, the high pressure sodium lamp, has become one of the most important light sources for outdoor lighting thanks to its high luminous efficacy (about 140 lm/W), good color rendering via its golden white color appearance and long lamp life (24,000–32,000 h; … High pressure sodium (HPS) lights are commonly used for outdoor application like parking lot lighting, street lights, etc. High Pressure Sodium Light Bulbs & Lamps 62 products Light bulbs and lamps install into light fixtures to provide general area lighting or more focused lighting for specific applications. [Your go-to guide]. After that the arc then heats up the mercury and the mercury vapor then lights, giving the lamp a bluish color. A lamp breaking is extremely unlikely to have any impact on your health. High-Pressure (SON). event a lamp is broken. High voltage energy is sent through ignitor through the arc tube. Benefits. HPS Lamp is the better version of its counterpart LPS Lamp. If a lamp breaks, ventilate the room for 30 minutes and remove the parts, preferably with gloves. This blog showcases in detail the working of High-Pressure Sodium Vapour Lamp. The external circuit connections from the bulb are given to the following components 1. EFFICIENCYAstra's High Pressure Sodium Vapour Lamps are economical light sources for outdoor lighting. Mercury vapor lamps have found the greatest use in industrial applications and outdoor lighting, because of their low cost and long life, and lamp sizes of up to 1,000 watts. Generally, the vapor pressure is lower and the starting gas is ionized more easily with this configuration than it is with convention probe start metal halide lamps. The heat generated by the arc then vaporizes the mercury and sodium. Because their output is much more pleasant to look at, they have replaced mercury vapor in streetlight applications. The high pressure sodium HID bulbs available at 1000Bulbs.com supply parking lots, construction sites, gymnasiums, and warehouses with a high intensity, yellow-toned light. A lamp breaking is extremely unlikely to have any impact on your health. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light.The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. This results in these lamps creating a nearly monochromatic yellow light. Standard HPS lamps produce a golden white light when they reach full brightness. In other wo… High Pressure Sodium lamp with opalized ovoid outer bulb. ©2019-2020 Signify Holding. A high pressure sodium lamp includes discharge vessel (20) which is enclosed with intervening space (1) by an outer bulb (10), which space contains a gas-fill with at least 70 mol. These indoor settings include warehouse and shipping areas and some manufacturing areas. Waste Disposal Method: All high pressure sodium lamps contain some amount of mercury. The arc tube consists of frame and is highly pressured with sodium for better efficiency. It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. It consists of 4 connecting ports … The high-pressure sodium (HPS) lamp is widely used for outdoor and industrial applications. Figure 4: High Pressure Sodium Lamps . SON-T Pro is a cost-efficient and reliable solution in High Pressure Sodium. Its higher efficacy makes it a better choice than metal halide for these applications, especially when good color rendering is not a priority. High-pressure sodium lamps turn 50% of the electrical energy into visible light. 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. This blog showcases in detail the working of High-Pressure Sodium Vapour Lamp. Low-pressure sodium lamps (LPS lamps) are normally made with a cylindrical or U-shaped glass tube with a length of several centimeters. Do not use a vacuum cleaner. High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas. Browse the The start of lighting up process begins through pulse start. Control gear must include end-of-life protection (IEC60662, IEC 62035) The spectral output of LPS lamps is incredibly focused at two wavelengths 589 nm and 589.6 nm. A localized version is available for you. 94 13.2. If a lamp breaks, ventilate the room for 30 minutes and remove the parts, preferably with gloves. 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. A typical high pressure sodium lamp will last longer than a metal halide lamp of similar wattage. This test is used to determine if an item can be managed as hazardous The mercury helps add a blue spectrum light to the pure yellow of the sodium. A Low-Pressure Sodium Vapor lamp (or LPSV lamp) is termed as a “miscellaneous discharge lamp” as it possesses some characteristics of High-Intensity Discharge (HID) lamps as well as it resembles fluorescent lamps in other areas. Although sodium vapour lamps produce much higher light output (about 90 lumens/watt) they cannot be used in lighting applications where colour-rendering property is very crucial. Better efficiency, life and size are few of the advantages of HPS Lamp over LPS Lamp. Sodium is the last material to vaporize as sodium vapor strikes an arc over 240 C. The sodium is mixed with other impurities to create a more “white” light. There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). The mercury vapor lamp is a high intensity discharge lamp. Standard light bulbs fit a large variety of light fixtures. This low color rendering index essentially means that it is very difficult to differentiate between the different colors of objects illuminated by this lamp. , and other types of businesses browse the SON products and find the product that you are looking by.
