Lighting is a very important element in buildings, which affects the comfort and effect of a space. Lighting is a combination of art and design. Good lighting design can not only make the room look better, but also bring out a kind of artistic atmosphere. There are three main types of lighting used in buildings, ambient lighting, task lighting and accent lighting. Ambient lighting provides a basic level of illumination to see and move around the building, creating a comfortable environment. Task lighting is designed to make it much easier to perform specific tasks. Finally, accent lighting is used as a decorative element, highlighting specific items and drawing more attention. The choice of lighting should be based on its function, so that we can create an environment where people can enjoy the atmosphere and feel comfortable. True lighting can bring a totally different feeling, whatever it is warm and tranquil or dynamic and energetic. In addition, it is important to choose proper lamps for specific tasks. For example, LED lights provide illumination of a low power or high output while providing intense and uniform lighting; halogen lamps also have a bright light output and a long life. Therefore, when designing a space, the choice of lighting is very important, and the arrangement of lighting should be reasonable. Good lighting design can make the space more beautiful and comfortable, and this is why it is so important.
