Evaluation of Optical Performance of Low-Mounted Road Lighting Using Probeam Light Distribution
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
Ultimateobjective of road lighting is to provide the drivers with visual information for safe driving at night and from such a standpoint, installing the road lighting and securing the visibility are the optimal solution to reduce the traffic accident at night. Traditional pole lighting requires high installation cost for high lighting fixture and pole and energy consumption to raise the road luminance is high. To improve such a problem, low-mounted lighting system was developed but asymmetric light distribution at low level causes dazzling and higher cost than pole lighting is a fatal barrier. This study thus is intended to develop the road lighting system that illuminates forward at low height with the same principle as the car headlight in a bid to prevent dazzling and reduce the installation cost and energy consumption and as a result of evaluation, the problems including electrical charge, leakage light causing light pollution, dazzling and road spot were found to have been solved.
