Artificial Lighting Design
Artificial lighting may have to be provided, 1.where the recommended illumination levels have to be obtained by artificial lighting only 2.to supplement daylighting when the level of illumination falls below the recommended value 3.where visual task may demand a higher level of illumination
A lighting design has several stages. These are as follows:
1.Identification of the requirements for the lighting system, illuminance levels, colour requirements, available space, etc;
2.Selection of equipment, lamps, luminaires: lamps, which influence the lighting level, colour characteristics and efficiency of the lighting system; luminaires affect the efficiency with which the light is distributed and so affect lighting efficiency and uniformity
3. Design of the lighting system: lighting systems are designed to achieve a reasonably uniform distribution of light on a particular plane (usually horizontal), avoidance of glare with a minimum expenditure of energy. The most rudimentary form of lighting design is done using a manual calculation – the lumen method. However lighting design is increasingly done by computer.
4. System control: once a lighting system has been designed it can be controlled in such a way as to make maximum use of available daylight, through selection of appropriate switching mechanisms and daylight responsive controls.
