Lighting is the technology of illuminating an area, usually by artificial sources such as a lamp or flashlight.
Lighting design is concerned with illumination in different settings such as architectrual lighting and theatrical lighting.
Lighting or illumination is the deliverate application of light to achieve some practical or aesthetic effect. Lighting includes the use of both artificial light sources such as lamps and light fixtures, as well as natural illumination by capturing daylight.
Daylighting (using windows, skylights, or light shelves) is often used as the main source of light during daytime in buildings. This can save energy compared with artificial lighting, which respresents a major component of energy consumption in buildings. Without proper design, energy can be wasted by using too much light, or using out dated technology.
Proper lighting can enhance task performance, improve the appearance of an area and have positive psychological effects on occupants.
One of the core tenets of proper lighting is uniform illumination, which is required in many applications such as projection displays, LCD backlights, medical lighting, microscopy, solid-state lighting and general lighting.
Lighting fixtures come in a wide variety of styles for various functions. The most important functions are as a holder for the light source, to provide directed light and to avoid visual glare. Some are very plain and functional, while some are pieces of art in themselves.
Nearly any material can be used, so long as it can tolerate the excess heat and is in keeping with safety codes.
An important property of light fixtures is the luminous efficacy or wall plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt.
A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the “bulb” to the surroundings.
The more transparent the lighting fixture is, the higher efficacy.
Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability.
