Guidelines for lighting at computer workstations are given in DIN 5035, Part 2 and EU Directive 90/270/EWG. Its appendix contains the following minimum requirements:
Lighting
- General lighting and/or special lighting (task lamps) must be dimensioned and arranged so that lighting conditions are satisfactory and contrast between the screen and its surroundings is adequate, according to the type of activity and the viewing requirements of the user.
- Glare, reflex or reflections on the screen or any reflective surface must be avoided by arranging the objects in the work area according to the arrangement and technical properties of the artificial light sources.
Reflex and glare
- Computer workstations must be set up so that light sources such as windows, other openings, transparent or translucent partitions, bright items of furniture and light coloured walls do not produce reflections on the screen.
- Windows have to be equipped with suitable adjustable mechanisms for preventing or reducing the amount of daylight falling on the workplace.
For further technical information see the DIN 5035-7 and DIN 66234-7 standards. |
