Daylighting (utilizing home windows, skylights, or light cabinets) is usually used as the main source of sunshine during daytime in buildings. This can save energy in place of utilizing synthetic lighting, which represents a significant part of energy consumption in buildings. Correct lighting can improve task efficiency, enhance the looks of an space, or have constructive psychological results on occupants.
Indoor lighting is normally achieved utilizing light fixtures, and is a key a part of interior design. Lighting may also be an intrinsic part of landscape projects.
With the discovery of fireplace, the earliest type of synthetic lighting used to light up an space have been campfires or torches. As early as 400,000 BCE, fireplace was kindled in the caves of Peking Man. Prehistoric people used primitive oil lamps to light up surroundings. These lamps have been constructed from naturally occurring materials resembling rocks, shells, horns and stones, have been filled with grease, and had a fiber wick. Lamps usually used animal or vegetable fat as fuel. Tons of of these lamps (hollow worked stones) have been found in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) have been also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps have been also invented
