Lighting plays an important role in our lives. Whether it is day or night, people have to use light to see things. But it is not enough for people to be able to see things with light alone, they also need lighting to beautify their environment. At home, lighting is used for livability. It provides a feeling of warmth and safety for us. We use different types of lighting fittings according to different rooms and occasions, such as bedroom lighting fixtures, living lighting fittings, dining room lighting, etc. Even if there is natural lighting, we still need proper lighting fixtures according to the specific situation of our rooms. In this way, different lighting fixtures can make people's living environment look completely different. In other places, such as offices, conference rooms, shopping malls, movie theaters and restaurants, lighting is used to create a special atmosphere. Different colors and combinations of light can give us completely different feelings. For example, in a restaurant, romantic and warm lighting can bring a romantic atmosphere; in a party hall, colorful dynamic lighting can create a warm and lively atmosphere; in a movie theater, a dreamy and mysterious atmosphere is created by gentle light and shadow. Lighting is indeed essential for our lives. By using different lighting fixtures, we can give the space we live in a completely different look and feel.
