Lighting, the key element of architecture, plays an important role in the establishment of a living environment. There are three general types of lighting sources. The first is natural light, which is derived from the sun and moon. Secondly, artificial lighting, which can be broken down into two categories: man-made lighting that is built and used indoors, and outdoor lighting which provides illumination during hours of darkness. Finally, there is a third source, lighting that is designed and used as an artwork or decoration. Natural lighting enhances living spaces with its soft, comfortable, and non-intrusive glow. It is the basis for the design of interior spaces, as well as a great source of psychological and emotional comfort to many individuals. The special quality of natural light makes it the most preferred choice of many architects and interior designers. Artificial lighting is designed to mimic the effects of natural light. It is used to amplify the mood and performance of indoor environments. Different types of lighting arrangements can be used to provide illumination for different purposes. For example, different colors and intensity of light can be used to create different ambiances in a space. Lighting art is a rising trend amongst the modern lighting designs. Lighting art and fixtures are used to create an artful atmosphere in any living space and are designed to operate in various ways. From wall and ceiling installations to custom artwork, new-age lighting art provides an interesting way for people to explore and express their creativity. Lighting, whether natural or man-made, plays a major role in creating a living environment. Architects, interior designers, and lighting professionals help us make the most of the available natural and artificial lighting elements and create beautiful and functional living spaces.
