The principles of ergonomics form the basis of the criteria and solutions to be used for office lighting because, like furniture, shape of the space and light plays an essential role in guaranteeing the comfort of workers and the quality of their work.Office environments recently have become so pervasive, typical lighting design solutions have become simplistic and formulaic in nature. http://www.gelighting.com/LightingWeb/na/solutions/industry/office/overview/
The ceiling is the preferred location for luminaires and their positioning depends on the size of the room and how the workstations are organised. The main aim is to guarantee visual comfort with adequate light levels, balanced luminance and the absence of direct glare or glare reflected by the furniture or computer monitors.
For office lighting indoor ceiling-mounted luminaires and ceiling recessed luminaires are most commonly used, with fluorescent lamps which have electronic ballasts. In the versions compatible with the DALI protocol, together with the light control systems, the light flow can be automatically regulated in the quantity necessary and for the time actually needed, further reducing energy consumption. Luminaires intended for office lighting have reflectors and lenses which allow the elimination of glare in working environments, in accordance with international technical standards. Today’s workplace is a complex and fluid environment, involving a wide range of visual tasks. Minimum glare on screens, low luminance contrasts around the workstation, energy cost reduction and efficient and effective office lighting are few key requirements. http://www.iguzzini.com/office_education_lighting
