Issue Date: | 2019 | Publisher: | PERGAMON-ELSEVIER SCIENCE LTD | Source: | Building and environment, 166 (Art N° 106389) | Abstract: | Fall accidents on stairs occur regularly and can cause serious injuries. The risk of accidents increases with age. Many contributing factors are related to stair accidents such as personal and environmental factors. The presented research focuses on the influence of several lighting conditions on the perceived safety of a staircase in a dark environment. A mock-up staircase was built and the lighting consisted of a LED strip in the handrail illuminating the staircase and two LED strips in each stair nose mounted upwards and downwards. In total, 30 elderly observers evaluated the staircase on how safe they perceived the lighting scenes in order to descend the stairs. Results show an increased perceived safety when using the LED strip in either the handrail or the stair nose illuminating downwards. An increased intensity of the LED strip illuminating upwards resulted in a substantial decrease of the perceived safety. A model that accurately predicts the perceived safety is proposed. Input parameters of the model are the measured luminance values of the staircase. The model could also be used to design a staircase with an appropriate luminance distribution. | Notes: | Van de Perre, L (reprint author), Katholieke Univ Leuven, ESAT Light & Lighting Lab, Gebroeders De Smetstr 1, B-9000 Ghent, Belgium. laurens.vandeperre@kuleuven.be; stefan.danschutter@bbri.be; kim.janssens@uhasselt.be; peter.hanselaer@kuleuven.be; marc.dujardin@kuleuven.be; kevin.smet@kuleuven.be; wouter.ryckaert@kuleuven.be |
