Light and lighting - Measurement and presentation of photometric data of lamps and luminaires - Part 1: Measurement and file format

This standard establishes general principles for the measurement of basic photometric data for lighting application purposes. It establishes the measurement criteria needed for the standardisation of basic photometric data and details of the CEN file format for electronic data transfer. In addition to it being a valuable standard in its own right, this standard has been written in two parts to provide the basis of photometric measurement in part 1 and verification and presentation techniques for specific lighting applications in part 2.

EN 13032-1:2004+A1:2012 (E) 5 Introduction The provision of reliable and accurate photometric data is a basic requirement for any lighting engineer in order to design a good lighting scheme. This European Standard aims to put on a common basis current European lighting practices so that a luminaire with its associated performance data, purchased in one country, can be directly compared and accurately em-ployed in another country. The standard is a guide to procedures referring where necessary to the relevant CIE, ISO and CEN publications. The reliability of these data depends also on well defined qualifications about the management, the organisation and the metrological referability of the Laboratory and the skill of the staff. !Due to the specific handling requirements for T16 and compact fluorescent lamps, these lamps are covered separately (normative Annex F)."

involves the use of a co-ordinate system in order to define the di-rection in which the intensity measurements are made; the system used is a spherical co-ordinate system with the centre coincident with the photometric centre of the luminaire. From a general point of view the co-ordinate system consists in a group of planes with a single axis of intersec-tion: the polar axis. In this system a direction in space is characterised by two angles: a)-

the angle between the plane taken as a conventional origin and the half plane containing the considered di-rection; b)

- the angle between the polar axis and the considered direction or the complement of this angle. The orientation of this system with respect to the first axis and the second axis (see Figure 1) of the luminaire is chosen with particular regard to the type of luminaire, to the type of lamp, to the mounting attitude of the luminaire and its application, in order to perform more accurate measurements or to simplify the consequent lighting calcu-lations. The identification of the first axis and the second axis shall be defined by the manufacturer or the photometric laboratory according to this standard. The third axis is the axis containing the photometric centre and perpendicu-lar to the two first axes. For information on the location of the photometric centre see clause 5.8. NOTE Usually the first axis of a luminaire is perpendicular to the light emitting area of the luminaire. As the light emitting area is not always clearly defined and could be curved, the relationship between this axis and a mechanical feature of the lu-minaire should be declared (e.g., the design attitude for road luminaires or the front glass for floodlights and for ceiling mounted luminaires the surface upon which the luminaire is mounted).

Key 1 First axis 2 Second axis 3 Third axis 4 Photometric centre Figure 1 — Photometric centre and photometric axes of the luminaire 4.2 System of measuring planes 4.2.1 General In general the luminous intensity distribution of a luminaire is measured in a number of planes. From the variety of possible measuring planes three systems of planes have been historically used and were identified by the CIE as A-, B- and C-planes.

The same terminology is adopted in this standard, but A-planes system is disregarded. The C-planes system is to be considered as the recommended standard system. The B-planes system may also be used, in particular for the photometry of luminaires such as floodlights. Any two of these planes with an angular difference of 180° will form a plane in the mathematical sense. 4.2.2 B-planes3 The totality of B-planes (see Figure 2) is the group of planes for which the line of intersection (polar axis) goes through the photometric centre and is parallel to the second axis of the luminaire. B-planes are marked with angles Bx with -180° ≤ Bx ≤ +180°. Within a plane directions are given by the angle β with – 90° ≤ β ≤ + 90°. The system of B-planes is coupled rigidly to the light source and follows its tilt if the lumi-naire is tilted. The photometric centre of the luminaire lies in the centre of the co-ordinate system. The first axis of the luminaire lies in plane B0, is perpendicular to the polar axis through the photometric centre and points in the direction β = 0°. The second axis of the luminaire is coincident with the polar axis.

Key 1 First axis 2 Second axis, polar axis 3 Third axis 4 Page = B-Plane Figure 2 — Luminaire orientation for B-planes Conventions related to the choice of axes linked to the luminaire: 1) The first axis of the luminaire is the axis through the photometric centre and perpendicular to the plane which is representative for the main light emitting area. SIST EN 13032-1:2004+A1:2012

EN 13032-1:2004+A1:2012 (E) 10 2) For floodlights the second axis of the luminaire generally is parallel to the spigot or tilting axis of the lumi-naires. If orientation of the lamp requires a different orientation of the second axis, it shall be stated by the lamp manufacturer or the photometric laboratory. 3) For luminaires other than floodlights containing linear single or double ended lamps, the axis of the lamp or the geometric axis of multiple lamps, is chosen as the third axis of the luminaire, perpendicular to the two first ones. Thus the transverse plane to the lamps of the luminaire, which is generally the most extensive light emitting plane, lies in the B0 plane (for luminaires with a symmetry in this transverse plane in B0 /B180 plane). 4) For other luminaires with the lamp axis coincident with the first axis of the luminaire, for other luminaires with multiple lamps or for other luminaires where no lamp axes can be defined, the luminaire shall be orientated that: a) the maximum intensity Imax of the light distribution is within the B0 plane or if Imax is located at β = 0° or if there are more than one location of Imax; b) the B0 /B180 plane is the symmetry plane of the luminous intensity distribution with the highest degree of symmetry. If the convention 1) or 2) is applicable or if different conventions are used, the choice of luminaires axes shall be stated by the manufacturer or the photometric laboratory, so as to clearly identify the luminaire alignment in the co-ordinate system, both for photometric measurements and for lighting calculations. 4.2.3 C-planes4 The totality of C-planes (see Figure 3) is the group of planes for which the line of intersection (polar axis) is the vertical line through the photometric centre. The polar axis does not necessarily coincide with the first axis of the luminaire, if the luminaire is tilted during measurements. C-planes are marked with angles Cx with 0° ≤ Cx < 360°. Within a plane directions are given by the angle γ with 0° ≤ γ ≤ 180°. The direction γ = 0° is oriented to the nadir.
