Basic knowledge

General lighting, also known as "background lighting" or "environmental lighting," is the basis of a lighting plan that refers to non-directional lighting that fills the room, creating a generally adequate lighting base for all activities in a space room.

Key lighting, also known as "decorative lighting," is a lighting method that specifies a particular object or area that illuminates the space to draw attention. It is often used to emphasize specific parts or furnishings of space, such as architectural elements, structures, kitchens, collectibles, decorations, and artwork.
