Solar powered LED Street light with auto intensity control is a new alternative to traditional street lightning system. There are many advantages of this system over traditional street lights. Solar powered street lights are environmentally friendly, cost effective and energy saving.
Solar powered LED street lights work by absorbing sunlight through the solar panel and converting it to electrical energy. Intensity of the street lights needs to be high during the peak hours and when the traffic on the roads decreases during the late hours, the intensity of the lights can be reduced till morning. This helps in saving energy. The street lights that work through a solar panel, switch on and off automatically. This process repeats daily. LED lights have a long life, and so solar powered LED lights are replacing traditional street lights all over the world due to their numerous benefits. Auto intensity control means that the intensity of the street light is controlled automatically during the peak traffic hours and completely switches off during the daytime.
The main components of this system include the following: 60W LED street lighting, a solar panel, a lead acid battery and solar street lighting controller. Requirement of the solar panel and the battery depends upon many factors depending upon the different weather conditions in different countries. The factors on which the requirement of solar panel and the battery depends are: daily sunshine hours, the time the system works every night, and a backup system during rainy days. Any country can save on electricity cost by using solar LED street lights. It can also reduce its environmental impact and eliminate the risk of hazardous disposal. The system has a long life and there is no need to spend money frequently. There is no need to change solar panels for 20-25 years, LED lights stay for 6-7 years and the life of a battery is up to 6 years.
