Lighting, one of the four main elements in interior design, is an important tool in helping to achieve an interior design scheme. Good lighting can help create an inviting feel, setting the right mood for the space, and highlighting certain accents or furniture pieces. In addition, it can add visual interest, help create certain illusions such as the sense of a larger space, and even help to reduce eyestrain and improve safety. There are a variety of styles of lighting available for use in interior design, from traditional fixtures such as chandeliers or sconces, to more modern lighting options like track lighting or recessed fixtures. Natural lighting can also provide another source of light, while being more energy efficient than other options. When choosing lighting to use in a room, it is important to think about the purpose of the room and the design aesthetic you are going for. Task lighting should be used in areas where work would be done such as a kitchen or office. Accent lighting brings drama and interest to a space while also highlighting certain features or pieces of furniture. Ambient lighting helps to establish the mood of the room, as well as providing a pleasing level of illumination. A combination of all three types of lighting makes for an inviting and easy to use space. Good lighting design involves creating layered lighting effects which work together to achieve the desired outcome. With careful consideration, the correct lighting fixtures, and the help of an experienced lighting designer, it is possible to create a perfect lighting scheme to suit any interior design project.
