Lighting is of vital importance in daily life. It can bring convenience and comfort to our home, office, and other places, and also improve our work or living efficiency. From the perspective of technology, the traditional light source is mainly based on non-renewable energy sources, such as incandescent lamps and energy-saving lamps. The energy wasted in use is very large, and the efficiency is low. Modern LED lighting technology, on the other hand, provides an effective solution. Compared with the traditional light source, LED lamps have the advantages of energy-saving and environmental protection. LEDs emit light with direct voltages and currents, with greater energy efficiency, no temperature rise and a longer lifetime. Besides, LED lighting products are often more easily customized according to the surrounding environment, and can bring about special lighting effects and changes. In recent years, the development and application of LED lighting technology has been rapid, and it has gradually become the most popular light source. Whether for family decoration lighting or commercial lighting applications, in a variety of indoor and outdoor scenes, LED lighting brings a new bright light to the city.
