Abstract
Department of Printed Electronics Engineering, Sunchon National University, Suncheon 540-950, Korea(Received July 21, 2014; Revised July 30, 2014; Accepted August 6, 2014)Abstract: Recently, LED lighting fixtures for crosswalk become popular in order to recognize the pedestrians at crosswalk, which can enhance the safety of the pedestrian at crosswalk. However, there are several problems related to the LED lighting fixtures for crosswalk, such as a lot of energy consumption due to a constant illumination during night and glaring of pedestrians at the opposite side of crosswalk. In this study, in order to overcome these problems, we have investigated a novel LED lighting fixture for crosswalk, which has two modules with different angles (60°, 120°). Illuminance of min and max at four-line city street crosswalk shown 50 Lux, 125 Lux, respectively. Illuminance of min and max at eight-line city street crosswalk shown 150 Lux, 200 Lux, respectively. Simulation investigation was optimized design using optical program. Prototype was verified measurement by goniometer system.Keywords: Crosswalk, Crosswalk light, Pedestrian, Light-emitting diodes, LED light, Light distribution
