It is concluded that solar lamp is an application product of photoelectric conversion technology, which has the advantages of energy saving, environmental protection, safety, no wiring, simple installation, automatic control, and the ability to change the insertion and placement position at any time as needed. The main types of solar lamps are solar garden lamps, solar street lamps, solar lawns, solar landscape lamps and solar signal lamps. International conventional energy prices have risen, and domestic energy supply is tight, so many cities are embarrassed to limit electricity. Energy substitution has risen to the height of national energy strategic security. As an infinite renewable energy, solar energy will gradually replace conventional energy for urban production and life, which is the general trend. As one of the important ways of solar energy utilization, solar lighting has been paid more and more attention by energy industry and lighting industry. At present, China's solar lighting technology is relatively mature, and the reliability of solar lamps has been greatly improved. The solar lighting lamps of advanced enterprises in the industry have reached or even exceeded the national lighting standards. It has strong popularization in cities with energy shortage and power failure and remote areas with difficulty in using electricity. There are successful models for reference in China, and the conditions for large-scale promotion of solar lighting lamps in China are ripe. At present, there are more than 100 solar lamp manufacturers in China, most of which are concentrated in Shanghai, Suzhou, Wuxi and Shenzhen. In the long run, the prospect of solar lighting system is very good. At first, people's consumption focused on practicality and low cost, but now the solar lighting system is developed according to the national conditions and people's feelings in China, with high cost performance. Judging from the current situation, solar lighting technology is the only mature technology that can be quickly applied nationwide. In recent years, the state has issued a series of preferential policies to support the development of renewable energy, including the Renewable Energy Promotion Law and the Medium-and Long-term Development Plan for Renewable Energy, which came into effect in 2006. This series of benefits is an encouragement and support for the solar energy industry.
Of course, the solar street lamp industry is also uneven. Huangchuan Limin Technology is not only a solar street lamp factory with independent patents, but also has been focusing on this field for more than ten years.
