Kapalı ofis ortamında OLED aydınlatmanın görsel konfor değerlendirmesi

Öz

Görsel konfor, iç mekanda kaliteli aydınlatmayı etkileyen önemli kriterlerden biridir. İç mekan aydınlatma uygulamaları için varolan çeşitli teknolojilerden akkor, fluoresan ve LED aydınlatma üç önemli dönüm noktasıdır. OLED aydınlatma gibi alternatif teknolojiler, göz ardı edilmemelidir. OLED aydınlatmanın görsel konfor üzerindeki etkisini yalnızca aydınlık düzeyi açısından araştıran az sayıda çalışma bulunmaktadır. Bu amaçla, bu çalışma, bir iç mekan ofis ortamında genel konfor parametreleri—genel konfor, aydınlık düzeyi, parıltı oranı, puslu yansımalar, renk, titreme etkisi, genel memnuniyet—açısından OLED aydınlatma koşullarının kullanıcının görsel konfor üzerindeki etkisini araştırmaktır. Çalışmaya, Çankaya Üniversitesi Mimarlık Fakültesi'nden toplam 12 öğretim elemanı gönüllü olarak katılmıştır. Test ortamı için OLED aydınlatma (2900 K) ile aydınlatılan tam-ölçekli bir iç mekan ofis ortamı tasarlanmıştır İç mekan ofis ortamında OLED aydınlatma koşullarının genel görsel konfor üzerindeki etkisini değerlendirmek için Ofis Aydınlatma Anketi benimsenerek değerlendirilmiştir. Daha önceki aydınlatma çalışmalarının aksine, bu çalışma aydınlatma koşuluna bağlı herhangi bir görev performansı ölçmemiştir. Bunun yerine yalnızca katılımcıların bir iç mekan ofis ortamında günlük rutinleri sırasında OLED aydınlatmaya maruz kaldıklarındaki görsel konfor değerlendirmelerine odaklanmıştır. Bu çalışma, doktora tezi üzerine yapılacak ileriki araştırmalar için bir ön çalışma niteliğindedir.

Visual comfort assessment of OLED lighting in an indoor office environment

Öz

Visual comfort is one of the significant criteria influencing good-quality lighting in an indoor environment. There are various technologies for delivering illumination in indoor installations; three important milestones are incandescent, fluorescent, and LED lighting. Alternative technologies, such as OLED (organic light-emitting diode) lighting, cannot be disregarded by a thorough examination. Few studies have investigated the influence of OLED lighting on visual comfort in terms of merely illuminance level. To this end, this study investigates the influence of OLED lighting conditions on visual comfort, including general comfort parameters—overall comfort, illuminance, brightness ratio, veiling reflections, colour, flicker effect, overall satisfaction—in an indoor office environment. Twelve members from the Faculty of Architecture, Çankaya University, voluntarily participated in the study. A full-scale indoor office environment was designed for the test environment, which was illuminated by OLED lighting (2900 K). An Office Lighting Survey was adopted to assess the general visual comfort of OLED lighting conditions in an indoor office environment. In contrast to earlier lighting studies, this study did not measure any task performance under the lighting condition. Instead, it focused solely on participants’ visual comfort evaluations when exposed to OLED lighting during their everyday routines in an indoor office environment. This study is a preliminary study for further investigations on the doctoral thesis.
