Light-emitting diodes in street and roadway lighting - A case study involving mesopic effects

The justification for the application of light-emitting diode (LED) technology to urban lighting is considered in this paper. It is suggested by the results that LEDs are convenient for architectural lighting and deserve to be considered for use in ambient lighting. The inclusion of mesopic effects into a comprehensive techno-economic analysis, which dealt with efficiency, maintenance and financial aspects of the use of LEDs in street and roadway lighting, was enabled by the recently developed Commission Internationale de l'Eclairage (CIE) mesopic system. It is concluded that the average energy savings when using LED instead of high-pressure sodium (HPS) luminaires amount to 19-26% for single-sided, staggered and opposite layouts, although they are frequently negligible if mesopic effects are not included. Even including mesopic effects, the total costs of the LED lighting solutions are 1.36 to 6.44 times higher than those of the comparable HPS lighting solutions. Therefore, for street and roadway lighting, LEDs are questionable.
