Get it as soon as Mon, Jan 4. If synthetic quartz is used, then the transparency of the quartz is increased further and an emission line at 185 nm is observed also. $42.50 $ 42. These lamps are mostly used for street lighting as well as industrial uses. Low pressure sodium lamps, the most efficient gas-discharge lamp type, producing up to 200 lumens per watt, it produce yellow light which is the only acceptable colour for street lighting and similar applications. During the early 1930s a third family of low pressure sodium lamp was developed by German Osram in an attempt to overcome this limitation. The alumina arc tube of a high pressure sodium arc discharge lamp contains a Penning mixture gaseous filling and also has an encircling wire ring starting aid, in order to reduce lamp starting voltage. Rather than a “cold spot,” the lamp’s “amalgam spot on pellet” regulates mercury vapor pressure during operation and yields up to three times the UVC output of a standard low pressure mercury lamp of the same length. Golden white light can penetrate, generally use at street, square, parking, place, bus stop, quay and factories. Low Pressure Sodium Lamp 35W Low pressure sodium vapour lamp (SOX 35w) emits monochromatic light and useful for many application Application in Street lighting, Tunnel Lighting, Polarimeter, Laboratory Experimental Use Imported from UK A high series resistance is provided in parallel with these wires so that once ionisation has taken place, the discharge transfers to the main electrodes. There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS). Bengaluru, Karnataka. Nordex offers a very range of hight pressure sodium lamps including North American and European system lamps. This low color rendering index essentially means that it is very difficult to differentiate between the different colors of objects illuminated by this lamp. In caso di prodotti che risultino avere difetti di fabbricazione, ricordiamo che comunque il materiale acquistato tramite SpesaElettrica gode delle normali garanzie e, in questi casi vi chiediamo di non esitare a chiamare il nostro servizio clienti. sodium-vapour lamp synonyms, sodium-vapour lamp pronunciation, sodium-vapour lamp translation, English dictionary definition of sodium-vapour lamp. 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. These types of lamps come in two varieties, i.e., low pressure sodium lamps and high pressure sodium lamps. 4.7 out of 5 stars 35. High Pressure Sodium Lamps Regular High Pressure Sodium Lamps Sodium lamps offer long life, high lumen output. High pressure sodium lamps are generally considered long-life, low maintenance, and relatively inexpensive lighting options. Low-pressure sodium (LPS) lamps have a borosilicate glass gas discharge tube (arc tube) containing solid sodium, a small amount of neon, and argon gas in a Penning mixture to start the gas discharge. Finally, one or more of the main electrodes may be preheated prior to lamp starting, so as to liberate electrons by thermionic emission. Lithonia Lighting F150SL 120 M6 1 Lamp 150W High Pressure Sodium Flood Light, Bronze. SOX(-E) low-pressure sodium vapour lamps have a U-shaped discharge tube, containing sodium, enclosed in an evacuated clear tubular outer bulb. Clicca il link seguente se vuoi negare il consenso ad alcune tipologie di cookie. With their extremely high luminous efficacy they are the most efficient light sources for road lighting, … CASSETTA DI DERIVAZIONE CON COPERCHIO BASSO E VITI A 1/4 DI GIRO - IP55 -DIMENSIONI INTERNE 150X110X70 - PARETI CON PASSACAVI - GRIGIO RAL 7035 The spectral output of LPS lamps is incredibly focused at two wavelengths 589 nm and 589.6 nm. Both of these features lead to a lower striking voltage, but bring the drawback of reduced efficacy owing to the fact that the current density of the discharge is higher than the optimum level. Because sodium vapour lamps cause less light pollution than mercury vapour lamps, many cities that have … This lamp has a distinctive yellow orange color that is familiar to many. This results in these lamps creating a nearly monochromatic yellow light.

Typical installations have to be re-lamped every two years whereas the expensive maintenance schedule can be extended to three or four years with high pressure sodium, and the reduced maintenance cost of the latter can totally offset the cost of energy savings with low pressure sodium.
