Paper Abstract

New concerns regarding the unwanted effects of lighting our nighttime environment (i.e., light pollution), and new efforts to design energy efficient roadway lighting installations, are changing the requirements of roadway lighting. These factors necessitate the need for different luminous intensity distributions with greater optical control than have traditionally been produced by roadway lighting fixtures. New requirements affecting the optical design of roadway lighting are presented. An example of a nonimaging optical design solution that addresses these requirements is given. Conclusions are then made about the challenges that lie ahead in the optical design of roadway lighting fixtures.
