Lighting, as we know, is an indispensable part of daily life. It plays an important role not only in providing illumination but also in home decoration. In the past, people used candles, oil lamps and gas lamps as the major lighting source at home. The use of such sources could provide light and a certain amount of warmth, but the process of preparation was complicated, the efficiency of lighting is low and the cost of fuel is high. With the development of science and technology, electrical lighting has become the main source of home lighting. Electric lighting is more convenient and efficient than traditional lighting sources. Not only can the light it provides be adjusted freely, but it also requires less energy to light an area and does not produce any smoke. The wide range of electrical lighting offers more choices for home decoration, and can make the home environment look much more beautiful. In summary, the emergence of electrical lighting has provided us with the best lighting solution, revolutionizing people's lives and bringing convenience and beauty into our homes.
