Energy and economic issues have increasingly become the bottleneck restricting social and economic development. The mineral energy currently used by humans is becoming increasingly exhausted and environmental pollution is becoming more and more serious. The focus of attention from all over the world. The task of developing clean energy that is renewable and does not pollute the environment is imminent. Solar power has the advantages of cleanliness, safety, extensiveness and adequacy of resources that cannot be compared with thermal power, hydropower, and nuclear power. It is considered to be the most important energy source in the 21st century. At present, solar energy application technology has made great breakthroughs, and has been more maturely applied to building corridor lighting, urban environment lighting, solar hot water supply and heating systems. In particular, the development of solar photovoltaic technology has brought broader prospects for the application of solar energy in lighting.

In the field of lighting, LED, as a new type of green light source product, is attracting the attention of the world. LED is called the fourth-generation lighting source. It has the advantages of energy saving, environmental protection, long life, fast response, and high luminous efficiency, and is used in a wide range of fields. In addition to being widely used in the display of electronic equipment and display screens, the application in the field of lighting can best reflect its energy saving. At present, lighting consumption accounts for about 20% of the total power consumption, and a significant reduction in lighting power consumption is an important way to save energy. If photovoltaic power generation technology and LED lighting technology can be perfectly combined, it will definitely make an important contribution to the sustainable development of mankind

Solar thermal also spans the two major industries of "new energy" and "energy saving and environmental protection". Solar energy is a clean and renewable green energy, and semiconductor light-emitting diode (LED) is also an environmentally friendly, energy-saving and efficient solid-state electric light source. The same is a PN junction semiconductor diode. The combination of solar photovoltaic power generation technology and LED lighting realizes the conversion of solar light energy into electrical energy, and then converts electrical energy back to light energy. The key to the perfect combination of solar photovoltaic power generation technology and LED lighting is that both are direct current, low voltage and can match each other. The combination of the two does not require an inverter to convert the direct current generated by the photovoltaic cells into alternating current, thus greatly improving the efficiency of the entire lighting system. In addition, solar photovoltaic power generation technology and LED lighting have the characteristics of environmental protection, energy saving, long life and safety. With the reduction of solar cell cost and the increasing efficiency, coupled with the improvement of LED light efficiency. The industrialization technology of solar LED lighting will be combined with urban construction, especially the development planning of energy and environment, so that LED lighting and energy-saving technology, the utilization of renewable clean energy and the promotion of new green lighting lamps will be considered as a whole. It can be predicted that the solar LED lighting industry will be a high-tech industry with great development prospects. It is not only a new growth point of the economy, but also can bring huge changes to the social environment and human life. Therefore, the research and development of high-efficiency and energy-saving new energy lighting technology has important practical significance for my country's sustainable development plan.

As a new type of green and renewable energy, solar energy has the advantages of large reserves, economical utilization, clean and environmental protection, etc. Therefore, the utilization of solar energy has been paid more and more attention by people.
