Paper Abstract

The LED luminaires are nowadays the mainstream of road lighting for the merit of durable, fast response, controllable, energy saving, and environmental friendly. For the evaluation of highway with LED lightings, we have recently developed on-site measurement of the photometric characteristics of lane and luminaire by luminance image, illuminance and spectral illuminance distribution which be evaluated as uniformity, colorimetry and glare parameters that were measured under the different height and spacing of the lampposts in the experimental field for expressway. We applied the image luminance measurement device to achieve the on-site and real time road lighting evaluation especially for the expressway. Some preliminary results were obtained from these experiments. These results will be applied to developing the standards and specification for road lighting in expressway.
