Lighting or illumination is the deliberate use of light to realize a practical or aesthetic effect. Lighting includes the use of both artificial mild sources like lamps and light fixtures, in addition to pure illumination by capturing daylight. Daylighting (utilizing windows, skylights, or mild cabinets) is sometimes used as the main source of light during daytime in buildings. This could save energy rather than utilizing artificial lighting, which represents a serious part of energy consumption in buildings. Correct lighting can enhance process efficiency, improve the looks of an space, or have constructive psychological results on occupants.
Indoor lighting is usually accomplished utilizing light fixtures, and is a key a part of interior design. Lighting may also be an intrinsic part of panorama projects.
With the discovery of fireplace, the earliest form of artificial lighting used to illuminate an space were campfires or torches. As early as 400,000 BCE, hearth was kindled within the caves of Peking Man. Prehistoric folks used primitive oil lamps to illuminate surroundings. These lamps were produced from naturally occurring materials comparable to rocks, shells, horns and stones, were stuffed with grease, and had a fiber wick. Lamps sometimes used animal or vegetable fats as fuel. A whole lot of those lamps (hole worked stones) have been discovered within the Lascaux caves in modern-day France, relationship to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented
