Daylighting (using windows, skylights, or gentle cabinets) is usually used as the principle source of sunshine throughout daytime in buildings. This may save energy rather than using synthetic lighting, which represents a major component of energy consumption in buildings. Proper lighting can improve job efficiency, enhance the appearance of an area, or have positive psychological effects on occupants.
Indoor lighting is usually accomplished using lighting fixtures, and is a key a part of inside design. Lighting can also be an intrinsic component of landscape projects.
With the invention of fire, the earliest form of synthetic lighting used to light up an area 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 similar to rocks, shells, horns and stones, have been filled with grease, and had a fiber wick. Lamps sometimes used animal or vegetable fats as fuel. A whole bunch of those lamps (hole labored stones) have been found in the Lascaux caves in modern-day France, relationship 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
