Lighting Lighting plays an important role in our lives. It has great influence on our moods, emotions and thinking. With the development of technology, lighting has become more and more complex, making it easier to adjust the intensity and color of the light. Take indoor lighting as an example. In the old days, people only used incandescent bulbs or fluorescent lamps to provide lighting. With modern methods like LED, halogen and xenon, people have more choices. LED lighting has become increasingly popular because of its energy-saving characteristics. Outdoor lighting is also important. It not only serves as guidance for people to move around, but also as decoration to beautify the environment. Lights on buildings can make them more attractive and fancier, and city lights can create an energetic atmosphere. Lighting can also affect our safety. Proper lighting can reflect the vitality of the area, decrease night-time accidents, and alert people to be aware of potential dangers. In conclusion, lighting is essential for our lives and an indispensable part of our environment. We should make full use of it and make sure that our surroundings are properly illuminated.
