Lighting is a key component in the design of any space. From the lighting needed for general tasks to the design accents, a good lighting plan will create a warm, inviting atmosphere. There are two main types of lighting, natural and artificial. Natural lighting, also known as daylighting, comes from the sun and is the most common form of lighting. It is cost effective, energy efficient, and importantly, changes throughout the day to create different looks and shadows. Natural lighting is also beneficial to people, as it can improve moods and productivity. Artificial lighting is used to supplement and enhance natural lighting. There are many types of artificial lighting, such as incandescent, fluorescent, LED, and halogen. These different lighting sources create different affects on the environment; some are brighter, some are warmer, so for different spaces, research into the effects of lighting can help to create the desired ambience. In addition to providing light, lighting can also be used as a design feature. Accent lighting, mood lighting, and under-cabinet lighting are all examples of how lighting can be used for design purposes. For a lighter, airy atmosphere, uplighting or wall lighting can be used, while for a more denselook, downlighting or layered lighting can be used. Ultimately, lighting should be tailored to the individual space and its needs. It should be used to create the desired atmosphere, to supplement and enhance the natural lighting, and to provide the necessary levels of brightness and warmth for a range of tasks. With a carefully planned lighting plan, any space can become a warm, inviting place.
