A
lighting device is required to provide minimum lighting level during the
operating time. Contamination on lighting device causes luminous flux to be
lost in lamp and structural imperfections to be formed on the surface of
optical elements. This deficiency in the performance of lighting makes
maintenance of lighting devices necessary. This effect formed by the common
effect of various parameters and implemented periodically is called maintenance
factor. Maintenance factor varies by lighting system, environmental conditions
and features of luminaires. In this study, calculation of maintenance factors
by years and change of lighting levels by different maintenance factors have
been analyzed for high-pressure sodium vapour luminaries in tunnel lighting.
Accordingly, increasing the maintenance factor used as multiplier in
performance calculations will decrease the energy consumed. Therefore,
increasing the Maintenance Factor increases the lighting efficiency.
