摘要

选择路灯时

需基于恰当的光度测量模型对不同类型路灯的发光效率进行比较。以两种常用路灯光源和两种LED路灯光源为研究对象

对道路照明环境中人眼处于的视觉状态进行了分析

进而通过MOVE模型求得这4种路灯在中间视觉状态下的发光效率。与明视觉状态下的发光效率比较

LED路灯和金属卤素路灯在中间视觉状态下的发光效率大大提高

而高压钠灯有所降低。中间视觉状态下

当环境照明亮度从0.03 cd/m

变化到0.1 cd/m

再变化到0.3 cd/m

时

标准LED路灯的发光效率首先从131.2 lm/W 降到122.7 lm/W

然后又上升到140.5 lm/W。结果表明

由于人眼视觉响应是随环境照明变化的

在中间视觉状态下LED路灯比常用路灯的发光效率高

通过光谱加强等优化方法可以得到发光效果令人满意的LED光源。

Abstract

To compare the luminous efficiencies of different street lightings

it is necessary to establish an appropriate photometric measuring model.In this paper

two kinds of traditional street lights and two kinds of Lighting Emitting Diode(LED) sources were selected for comparing their luminous efficiencies in the mesopic state and photopic state

then the MOVE model was used to derive the luminous efficiencies of the four kinds of lightings. Compared with the luminous efficiencies in photopic state

the luminous efficiency of the LED street lights and the Metal Halide(MH) lamps have improved significantly in the mesopic vision. However

the efficiency of the Hight Pressure Sodium(HPS) has decreased under the mesopic vision. Furthermore

when background luminance varies from 0.03 cd/m

to 0.1 cd/m

and then to 0.3 cd/m

the luminous efficiency of the LED street lighting in the mesopic visual state will decrease from 131.2 lm/W to 122.7 lm/W firstly but then increase to 140.5 lm/W. It is concluded that the sensitivity of human eye changes in the different brightnesses of backgrounds. Among HPS

standard LED light and modified LED light based on mesopic vision theory

the LED can offer the best solution in energy saving. Moreover

the LED lightings with more high efficiency can be obtained further by optimizing their spectra.
