Title:

Analysis of New Highway Lighting Technologies

Accession Number:

01531518

Record Type:

Monograph

Abstract:

This report documents and presents the results from a study of roadway lighting technologies including the use of light emitting diode (LED) sources and other light source types. A review of published research and case studies of new lighting technologies, as well as a comparison of roadway luminaire photometric performance, suggests that LED technologies, while still rapidly developing, are viable for specifying energy efficient and visually effective roadway lighting systems. New metrics such as luminaire system application efficacy can allow engineers to make informed decisions about the roadway lighting system configurations (including luminaire selection, spacing and mounting height) that will lead to the most economical system performance. Research also suggests that a number of other metrics such as mesopic photometry, brightness perception, and spectral sensitivity for discomfort glare could assist the designer in selecting among new lighting technologies, most of which have greater short-wavelength spectral output than conventional lighting mainly using high pressure sodium lamps. Evaluations of visual performance and visibility coverage areas from roadway lighting may also be of use in identifying appropriate adaptive control strategies for roadway lighting.
