Lighting or illumination is the deliberate use of sunshine to attain a sensible or aesthetic effect. Lighting contains the usage of each synthetic mild sources like lamps and light fixtures, as well as pure illumination by capturing daylight. Daylighting (using windows, skylights, or mild shelves) is typically used as the primary supply of sunshine during daytime in buildings. This may save energy rather than using synthetic lighting, which represents a significant part of energy consumption in buildings. Correct lighting can improve task efficiency, improve the looks of an space, or have constructive psychological results on occupants.
Indoor lighting is usually achieved using light fixtures, and is a key part of interior design. Lighting can be an intrinsic part of landscape projects.
With the discovery of fireside, the earliest type of synthetic lighting used to illuminate an space had been campfires or torches. As early as 400,000 BCE, hearth was kindled within the caves of Peking Man. Prehistoric people used primitive oil lamps to illuminate surroundings. These lamps had been comprised of naturally occurring materials equivalent to rocks, shells, horns and stones, had been stuffed with grease, and had a fiber wick. Lamps sometimes used animal or vegetable fats as fuel. Hundreds of those lamps (hole labored stones) have been found within the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) had been also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps had been also invented
