Today, many regions have replaced the traditional street lights with solar LED street lights. As an emerging energy saving product, solar street lights have gained the popularity with its advantages in simple installation, energy saving and environmentally friendly.
And do you know how was the street lights like before the release of solar street lights?
- The origin of street lights
The development of street lights is a history of pursuit of the brightness. The origin of street lights can trace back to 15century, with the purpose of brighten the darkness in 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.

- 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. Gas lamp lighting is not acceptable among people, but its advantage cannot be ignored and therefore has quickly become popular in the European countries.

After that, it was changed to gas lamp and the lighting has 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 a 10 horsepower internal combustion generating set with knife switch installed on each utility pole and requires manual operation.
- The emergence of the electrical lights
When it comes to the history of electrical lighting that human 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 emergence numbers in this type of bulbs, electrical lights have get on the stage of road lighting and replaced the gas lamps.
- High-pole street lights
City roads have become more complex as time develops. It will influence city’s appearance if street lights are installed on both sides of the road. Therefore, Beijing firstly use the high pole street lights.
- Birth of the new light source
People began to pay attention to the global environmental problem with the advent of 21st century and it is imperative to develop environmentally friendly and energy saving products. Then the 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 make it even more powerful.
From the development of the street lights, the street lights applied today is brighter, more beautiful and environmentally friendly. This is inseparable from the wisdom and sweats of predecessors. It is believed that in the future, street lights will step on the new stage and develops towards intelligent.
