Lighting refers to the application of artificial light to a specific place, typically for the purpose of creating visibility, augmented or managed light or to serve practical or decorative functions. Lighting consists of the use of both luminous and non-luminous materials to illuminate an area or to enhance an existing light source. Lighting is primarily a functional activity and its primary purpose is to provide illumination in a space. Lighting can also be used for aesthetic, decorative or safety purposes. Lighting can be used to frame objects, create depth, set the mood or highlighting a focal point in a room. The appropriate selection and placement of lighting in a room can be a major factor in creating the mood and atmosphere. Lighting effects can be used to create focal points, drama, and depth using shadows and contrast. With today's advancements and technology, lighting can be used to create incredibly diverse effects, from classic and modern to abstract and comic. Color temperature and lighting fixtures are other important lighting considerations, such as LED and halogen lighting. Lighting has also become a crucial element in the fields of architecture, photography and cinematography, allowing designers to create atmospheres that would not be possible with natural light. With modern lighting, it has become possible to create a desired atmosphere and mood for a space and achieve a host of lighting effects that enhance the design and provide a unique and remarkable aesthetic experience. Therefore, understanding the basics of lighting is an important knowledge for any designer to possess.
