Introduction
A lighting class is defined by a set of photometric requirements aiming at the visual needs of 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 and 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, 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 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 uniformity 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 E1R. An additional criterion, used in some countries, is 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 calculations 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 pedestrians 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 illuminance 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 classes 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 in 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 Each series of lighting classes presents decreasing requirements in their order and form steps of lighting level.
The specified lighting levels are maintained levels 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.
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 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, where relevant.
Installed luminous intensity classes for the restriction of disability glare and control of obtrusive light G*l, 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 environmental aspects.
Installed glare index classes for the restriction of discomfort glare DO, DI, 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 considered 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 pedestrian 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 perspective 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 s
