Evaluation of photobiological effects of fluorescent lamps used for general lighting purposes

摘要

There are limits for maximum exposure times to ensure photobiological safety (e.g. due to retinal injury) while at the same time opposite recommendations exists for phototherapy applications specially related to stimulating human circadian cycle (suppression of melatonin). This article summarizes properties of fluorescent lamps as part of lighting systems influencing our being in both positive and negative effects.. Evaluation is based on valued impacts (circadian factor, blue light hazard) in the visual range under different application conditions.
