High pressure sodium vapour lamp

Free Express Delivery On Orders Over £10. Online For Delivery Or Collection. 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 5nm.


Two varieties of such lamps exist: low pressure and high pressure. High Pressure Sodium Lamp (HPS Lamp ) The HPS lamp is the most ubiquitous lamp for street lighting on the planet.

The lamp is an improvement over the LPS lamp in that it has more acceptable color with the great efficiency of the sodium lamp. More buying choices £24. 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. They are commonly used in public parking lots, roadways, and other security areas. Get it by Tomorrow, Jun 14.

The arc tube is made of aluminum oxide and the sodium metal is combined with several other elements like Mercury which counter-balances the yellow glow with some white to light. High pressure sodium lamps are a little bit more complicated in their construction as they require a vacuum but have a relatively similar design. In HPS lamps there is an arc tube made of aluminum. How it works, inventors, variations. This lamp is the most popular lamp for street and outdoor lighting in the world due to its high efficiency and acceptable color rendering.


Save high pressure sodium lamps to get e-mail alerts and updates on your eBay Feed. Unfollow high pressure sodium lamps to stop getting updates on your eBay feed. 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 final advantage is that in the case of a momentary power supply interruption, the lamp will r. A lamp breaking is extremely unlikely to have any impact on your health. If a lamp breaks, ventilate the room for minutes and remove the parts, preferably with gloves.


Put them in a sealed plastic bag and take it to your local waste facilities for recycling. Do not use a vacuum cleaner. The fundamental principle behind the lamp is that the narrow, monochromatic sodium resonance lines can be considerably broadened if the sodium vapour pressure is increased.


Sodium - vapour lamp , electric discharge lamp using ionized sodium , used for street lighting and other illumination. In a high pressure sodium lamp , a compact arc tube contains a mixture of xenon, sodium and mercury. The xenon gas which is easily ionize facilitates striking the arc when voltage is applied across the electrodes.

The heat generated by the arc then vapo. 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.


The mercury vapor lamp is a high intensity discharge lamp. This is different from fluorescents which use the mercury vapor arc to create a weaker light that mainly creates UV light to excite the phosphors.
