Apparatus, method, and system for roadway lighting using solid-state light sources
Abstract:
Disclosed herein are apparatus, methods, and systems for illuminating roadways, paths, tunnels, bridges, and areas adjacent to such in a manner which minimizes glare and/or other adverse lighting effects commonly experienced by night-time drivers. According to aspects of the invention, horizontal and vertical aiming of a plurality of solid-state light sources permits projected light from a fixture to be tailored to roadway features (e.g., bends in the road) and in some cases, permits the mounting height of fixtures to be reduced which can make the envisioned system a cost-effective alternative to traditional roadway lighting.
