Its membership consists of the National Committeesin 39 countries and one geographical a

3、rea and of 11 individual members.The objectives of the CIE are :1. To provide an international forum for the discussion of all matters relating to the science, technology and art in the fields of light andlighting and for the interchange of information in these fields between countries.2. To develop

4、 basic standards and procedures of metrology in the fields of light and lighting.3. To provide guidance in the application of principles and procedures in the development of international and national standards in thefields of light and lighting.4. To prepare and publish standards, reports and other

5、 publications concerned with all matters relating to the science, technology andart in the fields of light and lighting.5. To maintain liaison and technical interaction with other international organisations concerned with matters related to the science,technology, standardisation and art in the fie

This work covers subjects ranging fromfundamental matters to all types of lighting applications. The standards and technical reports developed by these international Divisionsof th

CIE 1995CIE 117-1995IIIForewordThe past decade has seen many changes affecting lighting design. These changes include theintroduction of new types of lamps and luminaires, radica

32、l changes in work practices and an increasingcommunity awareness of the need for energy conservation and the wise management of resources.These changes have resulted in the need to revise the CIEs recommendations on discomfort glareprediction due, particularly, to changes in technology and workplace

33、 design and use.Two significant technological changes affecting discomfort glare have been:New lamps. The now commonly used 26mm diameter tubular fluorescent lamp has a lampluminance of approximately 11 kcd m-2. The 55 W compact fluorescent lamps luminance isaround 35 kcd m-2. Both have significantl

34、y higher luminances than the lamps that they havereplaced 38mm tubular fluorescent lamps with luminances of about 7 kcd m-2. The newlamps and others that are used in interiors might be considered as “retrofit” replacements butthe higher lamp luminances may require luminaire optical redesign to meet

35、comfort criteria.New luminaire designs. The replacement of prismatic lens panels with ”batwing” reflectors hasproduced luminaires with disymmetrical intensity distributions where the C0(crosswise)distribution is significantly different from the C90(lengthwise) distribution. This can allow greaterspa

36、cings to be used in the C0direction, resulting in the need for fewer luminaires and energyand capital savings. However, intensity values at high angles in the C45can be higher than ineither the C0or C90planes.Two major workplace changes affecting discomfort glare have been:Office design. Large open

37、areas with random arrangements of furniture are now common. Inthe 1940s and 1950s office furniture was arranged in a regular layout with the workers facing inthe same direction: either in the C0or C90directions. This meant that the ”worst case”discomfort situations were locations either in the middl

38、e of the end or side walls. In present dayoffices the furniture arrangement may be irregular with many and varied viewing directions.Screen based tasks and workstations. The introduction of screen based tasks has led toergonomic change in the workplace. The change with regard to discomfort glare is

39、that theoperators line of sight is much closer to the horizontal than for reading, writing or typing tasks.This means that more of the ceiling and more luminaires will be within the peripheral field of view more luminaires will be in the personal ”glare zone”.This technical report presents a unified

40、 glare rating formula developed from existing glare indexsystems. It also provides, in appendices, guidance on the production of the tables and curves neededto apply the system manually. Advice is given to designers on the use of the data.The following members of CIE Division 3, Interior Environment

48、ting (UGR) formula described in this technical report, combines features of theEinhorn and the Hopkinson formulae and incorporates the Guth position index. It may be regarded asbeing composed of the best parts of the major formulae in terms of practicability and of familiarity withthe results of gla

49、re prediction. The formula recognises the effects on the glare index of observerposition and direction of view.The report also describes, in the appendices, a tabular method, which uses reference values andstandard conditions, allowing the production of simple tables, similar to those for utilisation factors, foruse in luminaire data sheets.A rough estimate of discomfort glare is given by the luminance limiting cur
