Abstract

The present invention relates to a multi-dimensional road lighting system comprising a multi-dimensional lighting type and a luminaire dedicated for the multi-dimensional lighting. The multi-dimensional road lighting system is used in highway, municipal road and tunnel lighting. The multi-dimensional road lighting system comprises multiple dimensions of lighting subsystems including at least one dimension of backward lighting subsystem, one dimension of forward lighting subsystem and one dimension of lateral lighting subsystem. The lighting subsystems are formed by physical light sources. A light projecting direction of the backward lighting subsystem is opposite to the driving direction of a lane, a light projecting direction of the forward lighting subsystem is the same as the driving direction of the lane, and a light projecting direction of the lateral lighting subsystem is perpendicular to the driving direction of the lane. The multi-dimensional road lighting system of the present invention can at the same time or selectively provide multiple dimensions of space lighting. The present invention addresses the issues of glare, invalid illumination and poor longitudinal uniformity, significantly increases the lighting efficiency and power consumption and, at the same time, provides good road lighting photometry indexes and excellent cost/performance ratio, which can be used in illumination of new roads and reconstruction of existing road lamp systems.
