What type of lamp is a son?

What type of lamp is a son?

Philips SON light bulbs are discharge lamps, high pressure sodium vapor. These are the standard economical models. They offer a luminous efficiency of 130lm/W thanks to a discharge tube filled with a mixture of sodium and mercury and xenon starting gas. Each discharge lamp of the range has a E27 base type.

How does a son light work?

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. The lamp works by creating an electric arc through vaporized sodium metal. Other materials and gases are used to help start the lamp or control its color.

What is high pressure sodium lamp?

High-pressure sodium (HPS) lamps are part of the family of high intensity light bulbs that put out large amounts of light generally needed for street lighting and security lighting. The combination of metals and gasses within inside the glass tube produces an orange-white light commonly found in street lights.

Where are low pressure sodium lamps used?

The primary use of LPS lamps is for street and highway lighting as well as outdoor area and security lighting. The typical applications of LPS lighting include parking lots and garages, automobile and train tunnels, and street lighting. Indoor applications such as warehouses are practical where color is not important.

How long do sodium bulbs last?

High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours).

What is a SOX lamp?

n. an electric lamp in which sodium vapor is activated by current passing between two electrodes, producing a yellow, glareless light: used on streets and highways.

What is the difference between mercury lamp and sodium lamp?

The mechanism in mercury vapour lamp is more involved and sequential. Hence, the light from the mercury vapour lamp is white. Applications. 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.

What is a major problem in producing a high pressure sodium lamp?

Although the sodium light requires less energy that other types of light and is more efficient, there are drawbacks to the use of these light sources. Metallic sodium reacts with the moisture in the air and can explode if the bulb is broken.

What is the average life of sodium Vapour lamp?

The efficiency of a sodium vapour lamp under practical conditions is about 40-50 lumens/watt. Such lamps are manufactured in 45, 60, 85 and 140 W ratings. The average life is about 3000 hours and is not affected by voltage variations.

What is the average life of sodium vapour lamp?

Can you replace a high pressure sodium bulb with LED?

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. LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.

What is the difference between sodium lamp and LED lamp?

The biggest differences between LED and High-Pressure Sodium lights are color temperature and CRI. LED lights have a wider variety of color temperatures along with higher CRIs. LED Area Lights have a much easier immanence than High Pressure Sodium lights.

What makes a son high pressure sodium lamp?

SON High Pressure Sodium. Aluminium oxide (alumina) is the chosen ceramic since, when combined with minute traces of dopants to control the grain structure, it can be made translucent by a process which is suited to mass production. Once the ceramic tube is made, the problem of sealing an electrical conductor through it must then be faced.

What does the light from a sun lamp do?

The light from a sun lamp is believed to have a positive impact on serotonin and melatonin. These chemicals help control your sleep and wake cycle. Serotonin also helps reduce anxiety and improve mood.

Is the LPS lamp the same as the Sox lamp?

The energy used to make non-visible light is a waste of energy since it does not help do the principle job of an electric light. The LPS lamp is also called a SOX lamp (SO for sodium) If playback doesn’t begin shortly, try restarting your device.

What are the different types of sodium lamps?

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. The lamp works by creating an electric arc through vaporized sodium metal.
