Lighting, in architecture, is the art and science of enhancing the appearance of people and objects with light. It is a key component of interior and exterior design. Lighting can improve the beauty of a place, bring out the best in the materials used to create the space, and influence the overall mood and environment. Lighting plays an important role in making us feel safe and comfortable in the places we visit. A good lighting design should be both aesthetically pleasing and functionally illuminating. Natural light from windows and skylights should be maximized, but if necessary, there are numerous indoor lighting options to create the look and feel desired. Architectural lighting may be focused on particular areas, or distributed throughout the space, to provide evenly distributed illumination. In addition to providing a pleasant atmosphere and enhancing visibility, lighting should also be used to help conserve energy. LED lighting, for example, can dramatically reduce electricity costs and is long lasting and tough, making it an ideal solution for many lighting designs. Lighting is a powerful tool that can be used to create the desired environment and ambience, bring out the most in any space, and make us feel safe and secure.
