What role does solar LED street light play in urban lighting?1

Solar LED street lights play a good role in urban lighting development and management in the construction of urban lighting projects, and it can solve the problems of lighting and electricity consumption, while also reducing the peak electricity load, electricity expenses and maintenance costs, and reducing the pressure on the government . At present, the investment in the construction of urban lighting projects is relatively large. Urban lighting is the main lighting construction of urban spaces, which came into being with the continuous development of urban economy. This reflects the important carrier of urban cultural taste, and the largest expenditure for using electric lighting is The increase and expansion of electricity bills, the power supply system and the loss of lines, and the use of solar LED street lights and the configuration of LED light tubes to brighten the advertising door, the square lighting problem is simply solved, merchants and shops are also happy to receive this equipment, which is beneficial Development and management of urban lighting.　　The solar panel in the solar LED street lamp, also known as photovoltaic cell, is a kind of photoelectric element for energy conversion. After being irradiated by sunlight, it converts the energy of light into electrical energy. The current energy shortage in the world, peak avoidance and mandatory electricity curtailment measures are being adopted all over the world, and the government’s annual electricity expenditure for road lighting and urban lighting is relatively large, which increases the government’s financial burden, and it is increasing year by year. If there are more than 40,000 street lights in the city, with a total capacity of about 8,500kw, if the street lights are turned on and off according to the normal electricity time (4043 hours) every year, the electricity cost will be nearly 20 million yuan, while the maintenance funds allocated by the government (including electricity) are only more than 10 million yuan. It is difficult to meet the needs of normal maintenance, which seriously affects the social benefits of street lights.　　The use of energy-saving lighting equipment such as solar LED street lights has the power supply characteristics of independent lighting, no electricity costs are needed, and maintenance costs are relatively reduced, which greatly reduces the burden on the government and is worthy of promotion and use.
