Título Human sensitivity to flicker.
Información bibliográfica 1974, Vol.6, No.3, p.127-143. Illus. 67 ref.
Resumen Flicker of fluorescent lamps may have a fatiguing effect. To assess the importance of lamp flicker in offices, three types of study were undertaken: sensitivity to flicker (fusion threshold, influence of age on flicker sensitivity, electro-physiological study), measurement of cyclic light fluctuations of fluorescent lamps on 50Hz a.c. supply, office appraisals to assess attitudes of personnel and effects of flicker. The results reveal that significant numbers of people, especially young people, see flicker, and that the 50Hz component is the one which is normally seen. Lamp measurements show that this 50Hz light modulation remains at a low value for the first 7-8000h of operation and thereafter rises more rapidly. Planned lamp replacement is therefore essential. Discussion of the experiments.
