Glare evaluation system for use within outdoor sports and area lighting 用于户外运动和区域照明的眩光评估系统
发布日期: 1994-01-01
本技术报告描述了户外运动和区域照明的实用眩光评估系统。该系统既可用于检查现有装置的眩光情况(前提是有合适的测量仪器),也可用于在新装置的设计阶段预测眩光程度,但该系统的有效性仅限于眼睛水平以下的观察方向。对于这些应用的主要类别,规定了一般眩光等级限制。该报告涉及照明区域内或非常接近照明区域内的眩光和眩光限制,而非该区域外溢出光的影响。 大多数照明装置的质量可以用平均照明水平、均匀性和眩光限制来表示。到目前为止,还没有一个公认的户外眩光评估系统。通常用于机动交通道路照明的眩光概念“阈值增量TI”和“眩光控制标记G”不能直接应用于区域照明。这是因为观察者的视角是可变的,而不是固定的;照明点不一定位于规则的直线阵列中;安装高度和照明水平通常超出道路照明概念的有效范围。 照明装置引起眩光的程度取决于灯具的发光强度分布和瞄准、数量、布置和安装高度以及照明区域的亮度。本报告描述并推荐了一种实用的眩光评估系统,该系统考虑了上述所有因素。该系统基于广泛的现场测试,并已证明其适用于不同的装置,由于规格相同,具有足够的一致性。假设当抬头直视灯具时,通过仔细注意灯具相对于主要视线方向的位置,将所经历的不可容忍眩光问题保持在最低限度。 CIE关于各种泛光照明应用领域照明的报告在这方面提供了指导。在眩光评估概念被用作照明设计的实际辅助工具之前,有必要就标准的观察者位置和观察方向达成一致。指定标准位置和方向的目的是获取有关最高眩光程度和相对较高眩光程度区域大小的信息。对于室外区域照明装置的主要类别,规定了一般眩光限制限制。 本技术报告共14页,6图3表。
This technical report describes a practical glare evaluation system for outdoor sports- and area lighting. The system can be used both for checking the glare situation of existing installations, provided suitable measuring instrumentation is available, and for predicting the degree of glare at the design stage for new installations, but the validity of the system is restricted to viewing directions below eye level. For the main categories of these applications, general glare rating limits are specified. The report concerns glare and glare restriction in, or very close to, the lighted area and not the effect of spill light outside this area.The quality of most lighting installations can be expressed in terms of average lighting levels, uniformities and glare restriction. There has not, until now, been a generally accepted glare evaluation system for outdoor areas. The glare concepts, "threshold increment TI" and "glare control mark G", commonly used in road lighting for motorised traffic, cannot be applied directly for area lighting. This is because the direction of view of observers is variable and not fixed; the lighting points are not necessarily positioned in regular line arrays; and the mounting heights and lighting levels are often outside the ranges for which the road lighting concepts have validity.The degree to which a lighting installation causes glare depends upon the luminous intensity distribution and aiming of the luminaires, their number, their arrangement and mounting height and on the brightness of the illuminated area. This report describes and recommends for practical use, a glare evaluation system that takes into account all the above factors. The system is based on extensive field tests and has shown its applicability in different installations of adequate uniformity due to common specifications. It is assumed that the problem of intolerable glare experienced, when looking up and straight into a luminaire, is kept to a minimum by paying careful attention to the siting of the luminaires relative to the main directions of view. CIE reports on the lighting of the various kinds of floodlighting application fields give guidance in this respect.Before a glare evaluation concept can be employed as a practical aid in lighting design, it is necessary to agree on standard observer positions and viewing directions. Standard positions and directions are specified with the intention of getting information on both the highest degree of glare and on the size of the area with a relatively high degree of glare.For the main categories of outdoor area lighting installations, general glare restriction limits are specified.The Technical Report contains 14 pages, with 6 figures and 3 tables.
