Abstract

The purpose of this study is to investigate the effect of interior lighting on visibility of Thai senior. The experiment was carried out in a 3x3x2.5 m. laboratory room with several tested lamps installed on the ceiling at Mitraparp Female Elderly Home Care, Pathum Thani. The experiment was carried out using 82 Thai elderly as subject. The experiment was consisted of the study on visual performance, visual comfort and visual preference. Five factors were investigated, which are 1) task illuminance, 2) correlated colour temperature, 3) luminaire type, 4) room surface colour, and 5) the presence of window-view. The results suggested that the best visibility for Thai elderly task illuminance should be 1,000 lux with cool colour tone of light (4,200K) and cool colour tone of room surface, with natural outside view.
