Lighting is the use of light as part of interior design to achieve a practical or aesthetic effect. It can be used to provide illumination, accentuation, color, and dimension to a room. There are different types of lighting available for interior design, including ambient lighting, task lighting, and accent lighting. Ambient lighting is the overall illumination of a room. It can come from natural sources, such as sunlight, or artificial sources, such as lamps or ceiling fixtures. Task lighting is designed to provide light specifically for tasks, such as reading or food preparation. Examples of task lighting include desk lamps, wall sconces, and pendant lights. Accent lighting adds visual interest or helps to highlight an area, such as artwork or a piece of furniture. Examples of accent lighting include under-cabinet lights, uplights, and rope lights. For the optimal effect, lighting should be layered. This means having a combination of ambient, task, and accent lighting in the same space. The different types of lighting should work together to create an atmosphere that is both practical and attractive. Correctly done, lighting can add depth and definition to a room without being overbearing. By taking into consideration the use and functions of a particular space, designers can create beautiful and effective lighting design schemes. The use of the right lighting fixtures and the proper placement of them are key in creating an atmosphere that is both attractive and practical.
