Original title Kontrastbländning och reflexstörningar i kontorslandskap med bildterminaler [in Swedish]
Bibliographic information Arbete och hälsa - vetenskaplig skriftserie, Arbetarskyddsstyrelsen, Fack, 10026 Stockholm 34, Sweden, 1973:1, 16p. Illus. 1 ref. Price: Swe-cr.6.00.
Abstract The authors studied the lighting of an office equipped with 17 CRT display terminals and analysed complaints from the staff. Discomfort glare and reflections on the terminal screens were found to be the main causes of the complaints. Discomfort glare resulted from difference in luminance between the dark screen and other lit surfaces in the room. Reflections from windows and ceiling lighting appearing on the glossy screen were often found to have higher luminance values than the text on the screen. On the basis of these results, guiding principles are suggested for the design of lighting in similar workplaces.
