Light and lighting - Basic terms and criteria for specifying lighting requirements
This European Standard defines basic terms and definitions for use in all lighting applications. This European Standard also sets out a framework for the specification of lighting requirements, giving details of aspects which have to be considered when setting those requirements.
Licht und Beleuchtung - Grundlegende Begriffe und Kriterien für die Festlegung von Anforderungen an die Beleuchtung
Diese Europäische Norm definiert grundlegende Begriffe für alle lichttechnischen Anwendungen. Diese Europäische Norm legt auch Rahmenbedingungen für die Festlegung der Anforderungen an die Beleuchtung fest. Dabei werden Einzelheiten zu den Gesichtpunkten dargestellt, die bei Festlegung dieser Anforderungen zu berücksichtigen sind.
Lumière et éclairage - Termes de base et critères pour la spécification des exigences en éclairage
Svetloba in razsvetljava - Osnovni izrazi in merila za specifikacijo zahtev za razsvetljavo
Ta standard opredeljuje osnovne izraze za uporabo razsvetljave na vseh področjih; strokovni izrazi za omejena področja uporabe so podani v posameznih standardih. Ta standard tudi določa okvir za opredelitev zahtev za razsvetljavo, saj podaja podrobnosti o vidikih, ki jih je treba upoštevati pri določanju teh zahtev.

Lumière et éclairage - Termes de base et critères pour la spécification des exigences en éclairage
Licht und Beleuchtung - Grundlegende Begriffe und Kriterien für die Festlegung von Anforderungen an die Beleuchtung This European Standard was approved by CEN on 11 May 2011.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 12464-2, EN 13032-1, EN 13032-2 and EN 15193. The significant change between EN 12665:2002 and EN 12665:2011 is within the scope of the document.
EN 12665:2002 defined basic terms for use in lighting applications, and specialist terms with limited applications were defined in individual standards. In practice this resulted in cases of similar terminology being used to define different concepts, and conversely different terms being used to describe similar concepts. Therefore EN 12665:2011 defines basic terms and definitions for use in all lighting applications. Furthermore some references have been updated. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
The terms light adaptation and dark adaptation are also used, the former when the luminances of the stimuli are of at least several candelas per square metre, and the latter when the luminances are of less than some hundredths of a candela per square metre. NOTE 2
Adaptation to specific spatial frequencies, orientations, sizes, etc. are recognized as being included in this definition. [IEC 60050-845:1987/CIE 17.4:1987; 845-02-07]
3.1.2 accommodation adjustment of the dioptric power of the crystalline lens by which the image of an object, at a given distance, is focused on the retina
[IEC 60050-845:1987/CIE 17.4:1987; 845-02-44]
3.1.3 visual acuity 1.
qualitatively: capacity for seeing distinctly fine details that have very small angular separation 2.
quantitatively: any of a number of measures of spatial discrimination such as the reciprocal of the value of the angular separation in minutes of arc of two neighbouring objects (points or lines or other specified stimuli) which the observer can just perceive to be separate
[IEC 60050-845:1987/CIE 17.4:1987; 845-02-43]
3.1.4 brightness luminosity (obsolete) attribute of a visual sensation according to which an area appears to emit more or less light [IEC 60050-845:1987/CIE 17.4:1987; 845-02-28] SIST EN 12665:2011
3.1.5 contrast 1.
in the perceptual sense: assessment of the difference in appearance of two or more parts of a field seen simultaneously or successively (hence: brightness contrast, lightness contrast, colour contrast, simultaneous contrast, successive contrast, etc.) 2.
in the physical sense: quantity intended to correlate with the perceived brightness contrast, usually defined by one of a number of formulae which involve the luminances of the stimuli considered, for example: ûL/L near the luminance threshold, or L1/L2 for much higher luminances [IEC 60050-845:1987/CIE 17.4:1987; 845-02-47]
3.1.6 brightness contrast subjective assessment of the difference in brightness between two or more surfaces seen simultaneously or successively 3.1.7 colour contrast subjective assessment of the difference in colour between two or more surfaces seen simultaneously or successively 3.1.8 glare condition of vision in which there is discomfort or a reduction in the ability to see details or objects, caused by an unsuitable distribution or range of luminance, or to extreme contrasts [IEC 60050-845:1987/CIE 17.4:1987; 845-02-52]
3.1.9 flicker impression of unsteadiness of visual sensation induced by a light stimulus whose luminance or spectral distribution fluctuates with time [IEC 60050-845:1987/CIE 17.4:1987; 845-02-49]
3.1.10 visual field area or extent of physical space visible to an eye at a given position and direction of view NOTE
It should be stated whether the visual field is monocular or binocular. 3.1.11 visual performance performance of the visual system as measured for instance by the speed and accuracy with which a visual task is performed [IEC 60050-845:1987/CIE 17.4:1987; 845-09-04]
3.1.12 visual comfort subjective condition of visual well-being induced by the visual environment SIST EN 12665:2011
