Solar lamps are a kind of lighting device powered by solar energy. Solar lamps convert solar energy into electrical energy through solar photovoltaic cells, and then store it in a battery, and convert it into light energy through a light-emitting device. Solar lamps have many advantages, such as environmentally friendly, energy saving and convenient. Solar energy is effectively utilized and converted into electrical energy without harmful emissions. Solar lamps do not need complicated power line wiring and maintenance, and only need to absorb sunlight in order to automatically light up at night, saving energy and money. Solar lamps are widely used in homes, parks, courtyards, lawns, and roads. For example, when people go out for a walk at night, they can use solar lamps as lights, so that not only can they enjoy the scenery, but also ensure safety. In addition, solar lamps can also be installed in areas where it is difficult to build power lines, such as mountains and lakes, providing convenience for people who have difficulties in electricity. In recent years, solar lamps have become more and more popular. Not only are the sizes and designs of solar lamps becoming more and more exquisite, but the functions of solar lamps are also becoming more and more powerful. Solar lamps are becoming a new favorite of people in the family and outdoors.
