Today, many regions have replaced traditional street lights with solar LED street lights. As an emerging energy-saving product, solar street lights have gained popularity with their advantages in simple installation, energy-saving, and being environmentally friendly.
And do you know how was the street lights like before the release of solar street lights?
1. The origin of street lights
The development of street lights is a history of the pursuit of brightness. The origin of street lights can trace back to the 15century, with the purpose of brightening the darkness on the winter nights in London. The London market ordered to hang the lighting equipment outdoor, and this is the initial form of the street lights.
2. The coming of the “Bright Age”
“Bright Age” occurred in France in a 16century when Louis XIV issued an ordinance imposing public lighting in the city. Lights were therefore hoisted on the streets of Paris but they didn’t attract much attention during that time, yet today, the lighting often attracts whole people’s attention.
3. Street light revolution
Initial street lights use candles and oil and the lights are weaker. It became brighter when the kerosene is used, but the result is still not ideal until the appearance of the gas lamp. Gaslamp lighting is not acceptable among people, but its advantage cannot be ignored and therefore has quickly become popular in European countries.
4. Oriental Pearl TV Tower
The first street light in China is a kerosene lamp and was first appeared on the streets of Shanghai. When the night comes, everyone scrambled to go and get a glimpse of it. After that, it was changed to a gas lamp and the lighting improved a lot. Until 1879, China lit up the first electrical light but it was very difficult to apply electrical light during that time. It needs 10-horsepower internal combustion generating set with a knife switch installed on each utility pole and requires manual operation.
5. The emergence of the electrical lights
When it comes to the history of electrical lighting that humans use, we must think of Lodygin the Russian and Edison the American. Lodygin invented the incandescent lights and won the Lomonosov Prize. Years later, Edison improve this type of light bulb, the brightness is stronger and the cost is lower. With the emergency numbers in this type of bulb, electrical lights have to get on the stage of road lighting and replaced the gas lamps.
6. Solar street lights: High-pole street lights
City roads have become more complex as time develops. It will influence the city’s appearance if street lights are installed on both sides of the road. Therefore, Beijing firstly uses the high pole street lights.
7. Birth of the new light source
People began to pay attention to the global environmental problem with the advent of the 21st century and it is imperative to develop environmentally friendly and energy-saving products. Then a new light source was born, and LED is one of them. Its long service life and energy-saving stability make it widely available in the street lights industry. The solar power let the street lights can be able to generate electricity through the natural light sources and the new light source such as LED has made it even more powerful.
From the development of the street lights, the street lights applied today are brighter, more beautiful, and environmentally friendly. This is inseparable from the wisdom and sweat of predecessors. It is believed that in the future, street lights will step onto a new stage and develops toward intelligence.
