Detection of Luminance Level Tolerance in Tunnel Lighting Systems by Maintenance Factor

In this study, the effect of maintenance factor in tunnel lighting systems which are continuously working throughout the day has been investigated in simulation environment. The main parameters that constitute the maintenance factor are explained and calculated as the pollution factor in such parameters. It is understood that the performance factor of continuous tunnel lighting diminishes the factor of maintenance factor and it is seen that detailed maintenance factor should be used instead of standard maintenance factor. During the first installation of the tunnel, the calculated E% value should be added to other effects that cause performance loss and the maintenance factor calculation should be made. By performing these operations in simulation environment, the results of standard maintenance factor and detailed factor have been compared and the results have been evaluated
