ABSTRACT
The topics of this paper are mesopic dimensioning, glare properties and energy efficiency of LED street lighting. Road lighting luminance measurements and threshold increment (TI) measurements are made for four different LED street lighting installations. The effect of mesopic dimensioning on energy consumption and life cycle costs of the LED installations are examined. Through the calculations and measurements, the energy efficiency and glare properties of the LED installations are analyzed. The measurement results indicate that the measured and calculated threshold increment values differ from each other due to varying calculation parameters in real installations. It also shows that energy can be saved when mesopic dimensioning is applied to street lighting design.
