Lighting or illumination is the deliberate use of sunshine to attain a practical or aesthetic effect. Lighting consists of using both artificial mild sources like lamps and lighting fixtures, in addition to natural illumination by capturing daylight. Daylighting (using windows, skylights, or mild cabinets) is usually used as the principle source of sunshine throughout daytime in buildings. This may save energy rather than using artificial lighting, which represents a major part of energy consumption in buildings. Correct lighting can enhance process efficiency, enhance the looks of an area, or have positive psychological effects on occupants.
Indoor lighting is often achieved using lighting fixtures, and is a key a part of interior design. Lighting can also be an intrinsic part of panorama projects.
With the discovery of fire, the earliest type of artificial lighting used to light up an area have been campfires or torches. As early as 400,000 BCE, fireplace was kindled within the caves of Peking Man. Prehistoric folks used primitive oil lamps to light up surroundings. These lamps have been made from naturally occurring materials such as rocks, shells, horns and stones, have been stuffed with grease, and had a fiber wick. Lamps usually used animal or vegetable fats as fuel. A whole bunch of these lamps (hollow worked stones) have been found within the Lascaux caves in trendy-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
