Lighting plays an important role in our lives. It not only has the function of lighting, but also can create a better living environment. The most common are LED and incandescent lamps. LED lights not only save energy but also have a long service life, and the color rendering is very high. With the development of technology, the number of colors and shapes of LED lamps is also increasing. On the other hand, incandescent bulbs have lower energy efficiency and shorter life span, but their warm light can create a more comfortable atmosphere. In addition to lighting, smart lighting has also become a trend in recent years. It uses sensors and voice control technology to provide intelligent lighting control, so as to better meet the needs of different scenes. We can easily control the switch, brightness and color of the light through voice commands or by using a mobile phone, making it easier to adjust the atmosphere. It can be seen that lighting has gone far beyond its original function of providing lighting and is playing a more and more important role in our lives.
