Investigation of Photometric Flicker Phenomenon Effect on the Perception Level of Office Workers in Different Age Groups

Abstract

Abstract: Today, under the conditions where the number of office workers and artificial lighting applications have increased, although the effects of the Photometric Flicker phenomenon are serious, it is an issue that has not been understood in detail and people are not aware of it. Photometric Flicker phenomenon, which is a direct result of using ballasts or drivers with low power factor and lacking the necessary filtering features; It causes results such as decreased visual performance, loss of attention and perception. Considering that the conversion of LED luminaires is still not completed in many office buildings in the country, it is seen as an important requirement to investigate the Flicker effect in interior spaces that are considered to offer similar lighting levels and conditions, and to make a concrete due diligence by correlating this with the average age of office workers. For this reason, in this study, various tests and experiments were carried out with volunteer participants aged 18-30, 31-45 and 46 years of age and older without any significant vision problems, and the outputs of these studies were aimed to shed light on the relationship between age and lighting conditions.
