BS EN 13201-2:2015EN 13201-2:2015 (E) 4 Introduction A lighting class is defined by a set of photometric requirements aiming at the visual needs of

20、certain road users in certain types of road areas and environment. The needs can vary at different periods during the night and also in different seasons of the year, thus the recommendations may vary during these periods. The purpose of introducing lighting classes is to make it easier to develop a

21、nd use road lighting products and services in CEN member countries. The lighting classes have been defined with consideration of road lighting standards in these countries and the lighting classes defined in CIE 115:2010 (2nd Edition) aiming at harmonization of requirements where possible. However,

22、specific circumstances concerned with the road layout, use and national approaches based on traditional, climatic or other conditions could require different values of the uniformities. Not all the classes describe in this standard should be applied in a given country. The M classes are intended for

23、 drivers of motorized vehicles for use on traffic routes, and in some countries also residential roads, allowing medium to high driving speeds. The main lighting criteria of these classes are based on the road surface luminance of the carriageway and include the average luminance, the overall unifor

24、mity and the longitudinal uniformity for the dry road surface condition. Additional criteria relate to disability glare quantified by the Threshold Increment TI and the lighting of the surrounding areas quantified by the Edge Illuminance Ratio EIR. An additional criterion, used in some countries, is

25、 the overall uniformity of luminance in a wet condition. The C classes are also intended for drivers of motorized vehicles, but for use on conflict areas such as shopping streets, road intersections of some complexity, roundabouts and queuing areas, where the conventions for road surface luminance c

26、alculations do not apply or are impracticable. The lighting criteria are based on the horizontal illuminance and are expressed by the average and the overall uniformity. These classes have applications also for pedestrians and pedal cyclists. The P classes or the HS classes are intended for pedestri

27、ans and pedal cyclists on footways, cycleways, emergency lanes and other road areas lying separately or along the carriageway of a traffic route, and for residential roads, pedestrian streets, parking places, schoolyards, etc. The lighting criteria of the P classes are based on the horizontal illumi

28、nance on the road area and are expressed by the average and the minimum illuminance. The lighting criteria of the HS classes are based on the hemispherical illuminance of the road area and are expressed by the average hemispherical illuminance and the overall uniformity of this illuminance. The SC c

29、lasses are intended as an additional class in situations where public lighting is necessary for the identification of persons and objects and in road areas with a higher than normal crime risk. The EV classes are intended as an additional class in situations where vertical surfaces need to be seen i

30、n such road areas as toll stations, interchange areas, etc. The requirements of the lighting classes reflect the category of road user in question or the type of road area. Thus the M classes are based on the road surface luminance, while the C, P and HS classes are based on the illuminance of the r

31、oad area. The SC classes are based on semi-cylindrical illuminance, while the EV classes are based on the vertical plane illuminance. Each series of lighting classes presents decreasing requirements in their order and form steps of lighting level. The specified lighting levels are maintained levels

32、which are defined as the design levels reduced by a maintenance factor to allow for depreciation (refer to 3.10). The required maintenance factor, or a maintenance regime that allows deduction of the maintenance factor, should be included in tender specifications. BS EN 13201-2:2015EN 13201-2:2015 (

33、E) 5 It should be taken into account that the light output of some light sources is sensitive to temperature. As photometric data are generally published considering a reference temperature of 25 C, a correction factor should be considered for these light sources, if ambient temperatures are differe

34、nt. Environmental aspects of road lighting are considered in Clause 7 in terms of day time appearance, night time appearance and light emitted in directions, where it is neither necessary nor desirable. The purpose is to highlight criteria that can be included in tender specifications or similar, wh

35、ere relevant. Installed luminous intensity classes for the restriction of disability glare and control of obtrusive light G*1, G*2, G*3, G*4, G*5 and G*6 are introduced in the informative Annex A. The use of G* classes is mentioned in Clause 5 for conflict areas and in Clause 7 on appearance and env

36、ironmental aspects. Installed glare index classes for the restriction of discomfort glare D0, D1, D2, D3, D4, D5 and D6 are introduced in the informative Annex A as well. These classes are intended mainly for road areas lighted for the benefit of pedestrians and pedal cyclists. Additional items cons

37、idered in the Annex A are the use of installed luminous intensity classes and obtrusive lighting. Local lighting of pedestrian crossings is considered in the informative Annex B. The intention of local lighting is to attract the attention of drivers of motorized vehicles to the presence of the pedes

38、trian crossing and to illuminate pedestrians in or at the crossing area. For the C and P classes, disability glare conditions considering the TI are described in the informative Annex C. All photometric quantities are based on photopic photometry. From an energy efficiency and environmental perspect

39、ive a lighting installation should have a lighting level that matches the minimum required value of the relevant lighting class, and should meet all other relevant requirements, for instance uniformity, lighting of surrounding areas or additional classes (SC or EV). In that sense, the lighting level

40、s specified in the tables are target values for minimum maintained levels. Maximum lighting levels may be provided in tender specifications or national regulations. When designing new road lighting installations, all the lighting requirements specified in Clauses 4, 5 and 6 are relevant, and also re

41、quirements on environmental aspects as considered in Clause 7, should be complied with. When modifying the optical components or the geometry of existing lighting installations (for instance by changing the luminaires), it should be attempted to comply with all requirements. However, this may be hig

42、hly impractical or expensive in some cases, while deviations from one or more of the requirements may lead to more practicable and less expensive solutions. In such cases, decisions should only be taken after careful consideration of all the aspects. BS EN 13201-2:2015EN 13201-2:2015 (E) 6 1 Scope T

43、his part of this European Standard defines performance requirements which are specified as lighting classes for road lighting aiming at the visual needs of road users, and it considers environmental aspects of road lighting. NOTE Installed luminous intensity classes for the restriction of disability

44、 glare and control of obtrusive light and installed glare index classes for the restriction of discomfort glare are defined in the informative Annex A. Lighting of pedestrian crossings is discussed in the informative Annex B. Disability glare evaluation for conflict areas (C classes) and pedestrian

45、and pedal cyclists (P classes) is discussed in the informative Annex C. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Note 1 to entry: TI is a measure of the effect of disability glare, described as an equivalent veiling luminance caused by scattering of light in the human eye. TI values are calculated in accordance with EN 13201-3 by means of an equation for the equivalent veiling luminance which represents a young person. When setting requirements for the limitation of the TI, or when evaluating calculated TI values, it should be
