Maybe something has been with you for a long time and you don`t even feel its existence. We take it for granted that it`s only there until one day it can`t work again. We won`t think it`s important.
Street lights, is such an existence, have the little friends encountered street lights maintenance?
That night without street lights
Must be unpleasant
Because Fengyun some time ago
Riding a bicycle without street lights and falling over
Without street lights, the driving partners will not have much impact. After all, there are still lights to keep lighting, but for others, everything seems to be less friendly. You must know that a lot of reflective materials are used on the bicycle. To reflect other light sources to make it visible to others, similar to this is the reflective guardrails on both sides of the roadbed, and some special groups of work clothes, police, security guards, sanitation workers, etc., if there are no street lights It is difficult to be seen easily by others, which is tantamount to increasing the risk factor of night roads.
It can be seen that urban lighting equipment
For our production and life
Is already an essential part
Fire is an important step in the history of human development
The use of fire is a milestone in progress
Bonfire lit by ancient people

Street lamp for lighting

It is said that the first street lamp in the world appeared in Hyde Park in the United Kingdom to prevent bad citizens from committing crimes at night, not to facilitate people`s lives. It was not until the end of the 17th century that William III moved the palace to Kensington Palace. He found that night It is very dangerous to walk to St. James's Palace by yourself. 300 oil lamps were installed on the road, which became the earliest artificial street lamp in Britain. This road has also become the notorious "Road of Kings".
