Lighting design has undergone major changes over the centuries as new technologies have been developed. By controlling brightness and color, lighting can create a variety of effects. Lighting can be used to bring out the details of a space and create a stimulating atmosphere. Lighting is an important element of interior and exterior décor, with many interior design schemes making use of both artificial and natural lighting. In homes and other buildings, lighting can be used to highlight artwork, sofas, tables, and other pieces of furniture. Natural lighting, including sunlight, can be used to economically illuminate outdoor areas such as gardens and patios. The design and selection of lighting also affects energy consumption and the overall cost of a lighting system. Lighting can be powered using LEDs, fluorescent lights, halogen lamps and more. Specialized lighting technologies such as smart lighting are becoming more popular, offering a range of automated control structures. Lighting is a complex and interesting field of study, with its own specialist vocabulary, techniques, and concepts. With ever-changing trends and technologies, lighting is constantly evolving. There is much to learn about lighting, which is why many people find this field so fascinating.
