Working Principle of solar street light
The solar energy is converted into electricity which is stored in the battery through the solar
panel during the day time. The solar panel voltage will decrease gradually with the reduction of
solar radiation. When the solar panel voltage is lower than stipulated voltage, the battery will
supply electricity to load automatically through the controller; When the dawn comes, the solar
panel voltage increase gradually. After the voltage is larger than stipulated voltage, the
controller will cut off the electricity from battery and switch the energy supply to solar panel.ÿÿStructural feature

traditional light source, LED light source has following advantages
High lighting efficiency.
Incandescent lamp: 12-24LM/W. Fluorescent lamp: 50-70LM/W. Sodium lamp: 90-140LM/W. LED lamp:
50-200LM/W
Low power consumption.
The power consumption of LED lamp is 40%-60% of traditional lamps.
Long life span.
Life service life of LED lamp is 5 to 10 years.
Safe and reliable.
Low heat, no thermal radiation, tangible, cold light, free from glare, no toxic element like Mercury and Sodium
Eco-friendly
Shock proof, recyclable, no pollution, less lubricious attractive to insects, no bad impact on ecological
environment.
