İnsan Odaklı Aydınlatma

Abstract

Ozet Gecmis zamanlarda insanlar vakitlerinin cogunu dis ortamlarda ve gunes isigi altinda gecirmekteydi. Gunumuzde ise insanlar vakitlerinin cogunu ev, ofis, hastane, okul gibi kapali ortamlarda ve yapay aydinlatma kaynaklarinin olusturdugu isiklar altinda gecirmektedir. Gun isigi, gunesin konumundaki degisime gore gun icerisinde renk sicakligi, isik siddeti, isik rengi gibi parametrelerde degisim gosterdiginden dolayi dinamik yapilidir. Buna karsin yapay isik kaynaklari ile saglanan aydinlatma gun boyu sabittir. Insan sirkadiyen ritmi ve buna bagli biyolojik saati dunyanin aydinlik karanlik dongusu ile senkronizedir.  Dolayisiyla kapali ortamlarda maruz kalinan aydinlatmaya bagli olarak insanlarin sirkadiyen ritimlerinin bozulmasindan kaynakli sorunlar olusabilir. Insanlarin yasam ve calisma alanlarina gunes isiginin dinamik atmosferinin tasinmasi ve biyolojik saat ile sirkadiyen ritimlerinin bozulmasinin onlenmesi amacindan “insan odakli aydinlatma” fikri dogmustur. Yapilan calismada insan odakli aydinlatma ve etkileri ele alinmistir. Abstract In the past, people have spent most of their time in an outdoors and in the sunlight. Nowadays, people spend most of their time in an indoors such as home, office, hospital, school and under the lights of artificial lighting sources. Daylight is dynamic due to changes in parameters such as color temperature, light intensity, light color during the day according to the change in the position of the sun. In contrast, lighting provided by artificial light sources is constant throughout the day. The human circadian rhythm and its associated biological clock are synchronized with the light dark cycle of the world. Therefore, depending on the lighting that is exposed in indoor environments, problems may arise due to the deterioration of the circadian rhythm of people. The idea of human centric lighting emerged in order to create a dynamic atmosphere of sunlight in people's life and working areas and to prevent the deterioration of the biological clock and circadian rhythms. In this study, human centric lighting and its effects are discussed.
