Lighting is an essential element in any design project. From a functional perspective, lighting is essential for improving safety and visibility in a space. It can be used to define or compliment an area, archicturally, or to create an atmosphere. There are many types of lighting available to compliment any style or environment. Amongst them are task lighting, which is specifically used to illuminate a particular area or task; accent lighting, which gives emphasis to an accent piece; up lighting, which is used to highlight taller objects; and ambient lighting, used in a space to create the general atmosphere. Modern lighting technology has made it possible to switch between different lighting scenarios with far greater ease than in times past. Adjustable overhead lighting and wall switches that control different light sources throughout a space make it much easier to set the perfect lighting scene for the time of day or occasion. Additionally, energy efficient LEDs have revolutionised lighting, with practical applications in all areas. In addition to practical purposes, lighting implementation can have a significant impact on user experience. The right combination of lighting can help to lift a person's mood, or transform a room into a vibrant place for socialisation or relaxation. It is possible to create a sensation of depth and scale with careful lighting implementation. Overall, lighting is an essential element in any design project. Depending on the project, it can be used to provide practical purposes like safety and visibility, or to create atmosphere through user experience design.
