When night falls, LED solar lights and landscape lights of various shapes illuminate many streets, residential quarters, plazas and parks in Baoding, saving energy while facilitating citizens' travel and beautifying the urban landscape. Reduce the emission of harmful gases such as carbon dioxide. Like Baoding, other cities in Hebei Province have also begun to demonstrate the application of solar photovoltaic lighting technology, and achieved certain results.
According to the survey data of the provincial urban road lighting technical information terminal, the total number of street lighting lamps in the province and county is 1,090,800,000, the annual electricity cost is 348.91 million yuan, the annual maintenance fee is 119.21 million yuan, and the total annual operating cost is 468.12 million yuan. The annual urban road lighting consumes 436.13 million kWh of electricity, and the electricity consumption is equivalent to 1.199 million tons of standard coal, equivalent to 327,000 tons of carbon dioxide emissions. It can be seen that on the one hand, our province is facing tremendous pressure on energy conservation and emission reduction. On the one hand, urban development and new rural construction require a large amount of capital to invest in new lighting projects every year. The total demand for road lighting and high energy consumption form a contradiction. Solving this contradiction has become a new topic facing all localities.
In the past two years, Baoding, Shijiazhuang, Xingtai and other cities in our province have made useful attempts in applying solar lighting technology. The 13 sections of Baoding City installed and operated 484 bases of solar street lamps, accounting for 6.3% of the total number of urban roads; completed the construction of 8 gardens and green spaces in the 8th garden green space of the People’s University of China. It accounts for 79% of the urban garden and green space; completed the construction of a number of pilot district streetlights, landscape lights, garden lights, light boxes, etc. in Kangcheng Champagne Town and Xiulan Diamond Garden. The governments at all levels in Xingtai City also raised 35.79 million yuan to install solar street lights and garden lights in Guoshoujing Avenue to Xishan Hotel, Qilihe Xinhua Road Bridge, East Third Ring Road, Xingyi Industrial Park, Dahuoquan Park and Ningjin County. base. Shijiazhuang City also installed solar lighting 80 bases on two experimental sections.
In order to further promote the application of solar lighting, the province has set up a solar lighting application technology expert group to actively carry out pilot demonstration work of solar lighting, focusing on urban urban branch roads, urban-rural junctions and village road lighting as key demonstration areas. Gradually expand the scale and number of pilot demonstrations. At the same time, formulate solar lighting technology standards as soon as possible, and standardize related technologies and product quality. Some experts believe that through the practical application of solar LED lighting in recent years, under the current technical level, it is not suitable for applications such as urban main and secondary roads, which can be applied to branch roads, small streets and courtyards. , parks, residential areas and other places where lighting requirements are not high.

As the inexhaustible clean energy on the earth, solar energy is the most ideal green energy in the 21st century. The effective way to use it is to use photovoltaic power generation technology to convert solar energy into electricity. According to relevant experts, LED is a semiconductor device that can convert electrical energy into visible light. It has been used in the lighting field of many industries because of its energy-saving and pollution-free characteristics. Therefore, as an LED lighting system integrated with solar photovoltaic power generation, The perfect combination of a new generation of energy and a new generation of light sources. At present, solar LED lighting products have entered the application stage and become the most potential alternative to traditional lighting. At present, demonstration applications have been started in various parts of the province.
