Z1 Overall statement

Where a Commission Regulation specifies limits for parameters these limits shall be

used instead of the limits specified in this standard.
3 Terms and definitions
After 3.7 add new definitions 3.Z1 up to 3.Z7:
3.Z1
directional lamp

lamp having at least 80 % light output within a solid angle of π sr (corresponding to a

cone with angle of 120°)
[SOURCE: Regulation 1194/2012, Article 2]
3.Z2
beam angle

the angle between two imaginary lines in a plane through the optical beam axis, such

that these lines pass through the centre of the front face of the lamp and through

points at which the luminous intensity is 50 % of the centre beam intensity
[SOURCE: EN 61341]
3.Z3
partial luminous flux (of a light source, within a specified cone angle)

luminous flux emitted from a light source within a specified cone angle α determined

from the luminous intensity distribution I(θ, φ) of the source:
2π α / 2
= I(θ,ϕ)sinθdθdϕ (2)
∫ ∫
ϕ=0θ=0
Note 1 to entry: Partial luminous flux is expressed in lumen (lm)
Note 2 to entry: (θ, φ)=(0,0) is the direction of the cone axis
Note 3 to entry: The cone angle α is the full angle (diameter) of the cone
[SOURCE: EN 13032-4, 3.41, modified, – Notes 4 and 5 removed]

SIST EN 60662:2012/A11:2019
EN 60662:2012/A11:2019 (E)
3.Z4
useful luminous flux, Φuse

partial luminous flux of a lamp falling within the cone used for calculating the lamp’s

energy efficiency according Annex III, point 1.1 of regulation (EU) No 1194/2012
Note 1 to entry: Useful luminous flux is expressed in lumen (lm).

Note 2 to entry: The regulation specifies 90° or 120° cones according to the product characteristics.

Note 3 to entry: Useful luminous flux is similar to partial luminous flux. It is determined with the cone

axis coincident with the observed optical beam axis of the light source, the axis about which the luminous

intensity is substantially symmetrical.
3.Z5
efficacy
‘luminous efficacy of a source’, ‘light source efficacy’ or ‘lamp efficacy’
(ηsource)
means the quotient of the luminous flux emitted (Ф) by the power consumed by the
source (Psource). ηsource = Ф / Psource. Unit: lm/W.

The power dissipated by auxiliary equipment such as ballasts is not included in the

power consumed by the source
[SOURCE: Regulation 245/2009 Annex II, 1.a)]
3.Z6
Lamp Lumen Maintenance Factor (LLMF)

means the ratio of the luminous flux emitted by the lamp at a given time in its life to the

initial luminous flux
[SOURCE: Regulation 245/2009 Annex II, 1.b)]
3.Z7
Lamp Survival Factor (LSF)

means the fraction of the total number of lamps which continue to operate at a given

time under defined conditions and switching frequency
[SOURCE: Regulation 245/2009 Annex II, 1.c)]
4 General lamp requirements
After 4.3 add new sub clause 4.Z.1
4.Z1 Lamps for special purposes
Where a lamp is to be considered as a special purpose product according to
Regulation (EC) No 1194/2012 this shall be declared by the supplier.
8.3 Lamp warm-up test
Add a third paragraph as follows:

For determining warm-up time to 60% luminous flux, the test voltage shall be the rated

voltage of the reference ballast, measuring the time from lamp starting.

EN 60662:2012/A11:2019 (E)
8.9.Z1 After Subclause 8.9 add new Subclauses 1.4.Z1 to 1.4.Z5 as follows:
8.9.Z1 Useful luminous flux

The useful luminous flux of a directional lamp shall be measured under the conditions

of Annex G, by luminous intensity integration as described in EN 13032-4 , 6.3 "Partial

luminous flux".
Alternative measurement methods may be used if they can be shown to give

equivalent results for the product being tested, if necessary by applying correction

factors. Measurements with lamps operating horizontally are often much easier to

carry out. The reference method, however, uses the measurement position according

to Annex G, G.1.
In case of doubt a goniophotometry measurement of EN 13032-4 clause 6.3 shall be
used.

NOTE Below are a few examples of alternative measurement methods. It is not an exhaustive list.

• For small beam angles shine into integrating sphere.
• Mount lamp on internal surface of integrating sphere.
• Mount lamp inside integrating sphere with screening (LM-20 technique).

• Illuminate a surface and measure the illuminance across the surface with a photometer.

• Illuminate a surface and measure the surface luminance with a luminance camera.

• Illuminate a translucent screen and measure the surface luminance of the rear side with a

luminance camera
8.9.Z2 Efficacy

The efficacy of an individual lamp shall be calculated from a measurement of luminous

flux and power according to the conditions of Annex G.
8.9.Z3 Lamp lumen maintenance factor

The lamp lumen maintenance factor of an individual lamp shall be calculated from

measurements of its luminous flux made at appropriate times according to the
conditions of Annex G Lamp operation between these measurements shall be as
prescribed in Annex H..
8.9.Z4 Lamp survival factor

The survival of an individual lamp shall be determined by operating lamps under the

conditions prescribed in Annex H until the lamp fails to remain alight or delivers low

light output (in case of doubt, low light output refers to noticeably less than 50 % of

rated light output).
8.9.Z5 Mercury content
The average mercury content shall be measured in accordance with the CV AAS
method as described in EN 62321-4.
8.9.Z6 Sensitivity to luminaire ambient internal temperature
As high pressure sodium lamps operate at high temperatures, their photometric

characteristics are insensitive to the normal range of ambient internal luminaire

temperatures.

G.4 Measurement
Insert the following paragraphs in G.4 between the second and third paragraph.

Photometric characteristics shall be measured in accordance with EN 13032-1. For

determination of the centre beam intensity of reflector lamps, EN 61341 shall be used.

The chromaticity coordinates and correlated colour temperature (CCT) of an individual

lamp shall be calculated according to CIE 15 from a measurement made under the
conditions of Annex G.

The colour rendering index (CRI) of an individual lamp shall be calculated according to

CIE 13.3 from a measurement made under the conditions of Annex G.
