How do street lights work in actual?

Lights, known as street lights, mounted on poles spaced at intervals are just like twinkling stars. Silently illuminating our streets, roadways, highways, sidewalks, and several other public place areas, they don’t even let us how hard it gets to find the path, protect ourselves, and be safe in the darkness of the night. Street lights are also known as street lamps and not only show us our path in a better way but also offer numerous other benefits.

How do street lights work?

How street lights work is an astonishing but remarkable miracle of nature and a mesmerizing work of the brain of scientists. Although it is an era of LED street lights, still the most commonly used in street lamps all across the globe are the high-pressure sodium lamps (HPS). In the simplest of words, HPS produces light that spreads over quite a distance by passing electricity through a mixture of gases. Street HPS lamps are extremely efficient, durable, long-lasting, and need maintenance rarely. That is why such street lamps are widely used all over the world. However, other technologies such as high-intensity discharge (HID), metal halide, mercury vapor, low-pressure sodium, incandescent, and most recently light-emitting diode (LED) are also used in street lights.

How much electricity does a street light consume?

The 1900s was the era of incandescent lights that used to consume 320 watts and that was too much energy consumption. The high-pressure sodium lights consume 250 watts approximately and have offered a lot of energy-saving.

What type of material is used in the street lights?

Street lights have to withstand the outdoor elements and extreme weather conditions. Therefore, corrosion-resistance materials like aluminum or strong plastic material such as polyethylene are used in street lamps to enable them to endure outdoor conditions.

What are the advantages and benefits of street lights?

Street lights are a kind of unsung heroes. They have been silently serving the public for centuries now since the first street light was installed in Cordoba, Spain back in the 10th century. The primary function, as well as benefit of street lighting, is to illuminate streets, roads, and public places when the night brings darkness. They also offer various other benefits as well.

  • Street lights help pedestrians and other vulnerable road users who have to face decreased visibility if street lights aren’t there. So, they substantially reduce risks accompanying darkness.
  • Street lights substantially improve drivers’ safety. Driving during the night is always risky as almost 40% of accidents are reported to happen between 7 pm to 8 am. But, the accident percentages are reported to be significantly low on those roads and highways where street lights are installed.
  • Street lights bring crime rates to the lowest levels. That is a huge benefit of street lamps. Crimes usually take place in the dark where criminals snatch vehicles, rob, or do other crimes and vanish into the darkness. Street lights, however, don’t let the night spread darkness over our streets and roads. Thus, criminals cannot take advantage of the dark and that is how street lights help in controlling crimes.
  • Street lights also offer certain other benefits such as reduce glare from headlights of other vehicles, help drivers easily navigate, and so on.
