Solar Street Lights: True 'Green Lighting'

As an emerging green energy, solar energy has been rapidly popularized and applied due to its incomparable advantages. As the fourth-generation new light source, it has been effectively used in urban lighting and beautification, road lighting, courtyard lighting, indoor lighting and other lighting and applications in various fields. Especially in remote areas without electricity, solar street lamps have wider application prospects. Most people think that it is a great innovation that energy-saving lamps can save energy by 4/5, but LEDs can save energy by 1/4 than energy-saving lamps. This is a great innovation of solid-state light sources. In addition, LED also has the advantages of high light quality, basically no radiation, reliable and durable, and extremely low maintenance cost. It is a typical green lighting source. The successful development of ultra-bright LEDs has greatly reduced the cost of solar lamps, making them at or close to the cost quotation of the initial installation of the power frequency AC lighting system, and has the advantages of environmental protection, easy installation, safe operation, economical energy saving and so on. Due to the advantages of high light efficiency and low calorific value, LEDs have been increasingly used in the field of lighting, and have shown a trend of replacing traditional lighting sources. In western my country, solar street lights and solar garden lights on non-arterial roads have gradually become large-scale. With the vigorous development of solar lamps, green lighting is bound to become a trend.
