直线道路的 r（x，y）反射表和亮度计算
Reflection Table r (x, y) and Calculating the Luminance Distribution for Straight Roads
摘要
Abstract
Luminance evaluation is becoming more and more important in the road lighting evaluation, but the calculation work is lack to be seen in publication. Although the calculation of road-luminance distribution can be conducted using the luminance coefficients r (β, γ) table stipulated by CIE ( International Commission on Illumination ) , it remains a very difficult process.The root cause of the difficulty is that road-luminance distributions employ Cartesian coordinates, whereas the r (β, γ) table is based on spherical coordinates.A new luminance-coefficient table for straight road called r ( x, y) table based on Cartesian coordinates is introduced in this paper.This provides a new simple and visualized method for luminance calculation.The analysis of pavement reflection properties will be more intuitive visualization and the calculation of road luminance distribution also will be easier.The derivation method of r (x, y) table was given, and the analysis of the reflection coefficient in different pavement properties along the road direction and the vertical direction are discussed in detail.It is easy to calculate the luminance distribution of the single lane and whole road using r ( x, y) table.This will be a huge boost to analyze the road luminance distribution with given luminaire, as well as designing luminaires with isoluminance.关键词
