配光曲线对光污染影响的配光曲线对光污染影响的量化分析量化分析The Analysis of Luminaires Light Distribution for Reducing Light Pollution概述概述Abstract 光污染的四个焦点：Light pollution includes 天空辉光 Sky Glow 光侵扰 Light Trespass 眩光 Glare 能源浪费 Energy Waste 四个焦点在技术上都指向光的控制 All these four aspects should be technologically resorted to the light control 光的控制主要在于灯具的配光曲线设计 Light control mainly depend on the curve of light distribution国务院概述概述Abstract选用不合理的配光曲线的原因很多Many existing facts make us reluctantly to choose the lighting fixtures with unreasonable light distribution curves 设计者没有理解配光曲线的差别；The designers dont recognize the differences of light distribution curves among some similar lighting fixtures 设计者在规定的成本之下无法找到合适配光的器具；The designers cant find the suitable lighting fixtures with adequate light distribution curve especially limited by the budget 施工者与设计者之间没有进行充分的技术沟通；Lack of sufficient dialog and technical communications between the technicians and the designers 很多照明系统的建设队伍并没有受到专业训练。The construction teams dont have been trained to fulfill their professional lighting skills.控光不好控光不好Light not be well controlled天空辉光Unwanted Up-light Cause Sky glow 眩光Wrong position or Angle Cause

calculated result considered reflection,convergence coefficient0.2简单模拟了物体表面的实际反射系数，所以不同物体的亮度与照度图面上有区别。Simply simulated the surface of the objects actual reflection coefficient,so there exist differences in brightness and illuminance in render images案例一CASE 非截光灯具最容易产生无用的上射光通进而导致天空发亮Its most possible for non-cutoff luminaire to generate the useless upward luminous flux then cause sky glow.这是中等城市的一条小街道This is a street in a mid-sized city比较截光灯具与非截光灯具在相同环境条件下的上射光通量Comparison of the cutoff luminaire and the Non-cutoff luminaires upward luminous flux as generated under the same

即使采用截光灯具，也可能因配光不合适而造成上射光通Although we selected cutoff luminaires,the upward waste luminous also could be generated because ofunsuitable light distribution.这是某高速公路的收费站This is a toll station of the freeway.比较两种截光灯具由于配光曲线的不同而对天空造成不同的影响We evaluate the influence of the two cutoff luminaires with different light distribution to the sky.似乎这个案例对专业照明设计师来说不可想象，但实际上在国内比比皆是，即使是发达的大城市也随处可见。To the lighting

non-cutoff luminaire when the light is needed to project upward.It is very important to adopt special light distribution at special area because both decreasing the upward light and energy saving

IV光强分布不合理并非指灯具的配光曲线，因为配光曲线本身无所谓合理与不合理。光强分布不合理是指没能够选用合适的配光或没有充分调整不同配光灯具的布局The unreasonable luminous intensity distribution doesnt point to the luminaires light distribution curve,for its unmeaning to the luminaires light distribution curve itself reasonable or not.The unreasonable luminous intensity distribution means the suitable light distribution doesnt be selected or the position of luminaires

灯具的配光很大程度上决定了光污染程度；精心的挑选可以带来意想不到的效果；贵的不一定是好的，合适的才是好的，不必为预算所困；“正确的”灯具必须被“正确地”安装才是好的；防止光污染，照明设计师首当其冲。
