Cove lighting is one of the basic lighting techniques, a type of uplighting that directs light to the ceiling plane from a cove on one or more sides of a room to provide overall diffuse illumination. It is also referred to as ambient luminescence. Cove lighting is typically mounted to or incorporated into a wall, but it can also be located within a ceiling coffer. Cove lighting can be installed beneath a lip facing inward from a wall, shining directly onto the ceiling. The lights can be used to surround the perimeter or accent chosen sides for a stylised effect. Cove lighting is most commonly installed on ceilings because of the potential to be used as the primary lighting source if the bulbs are bright enough. Since cove lighting effects are usually quite eye-catching and dramatic, they are often used in theaters, bars, and unique living spaces.
For example, cove lighting can add warm elegance and drama to a formal dining room. The tops of the walls on all sides of the dining table could have a glowing lighting effect. Some dining room designs feature a tray ceiling withcove lighting accenting it. Tray ceilings are rectangular ceiling recesses that often containlighting fixtures in the recessed section.
