3.1.24 QUALITY CRITERIA

To ensure consistency in quality criteria the manufacturers shall submit data in accordance with

IEC/PAS 62717 Performance requirements – LED modules for general lighting and IEC/PAS

62722 Performance requirements – LED luminaires for general lighting. These documents were

developed together to provide; the definition of a set of quality criteria related to the initial

specifications of a product and a standardised description on how to measure

these quality criteria. The following list of quality criteria, as detailed in the Lighting Industry

Liaison Group – A Guide to the Specification of LED Lighting Products 2012, will be considered

during the evaluation process.

3.1.24.1 Rated input power. The rated input power shows the amount of energy consumed by

a luminaire, including its power supply. It is expressed in watts. 3.1.24.2 Rated luminous flux. This is the light emitted by the luminaire which is expressed in

lumens. For LED luminaires Absolute photometric values shall be used. 3.1.24.3 LED luminaire efficacy. The measured initial luminous flux divided by the measured

initial input power of the same individual LED luminaire. It is expressed in lumens per watt. 3.1.24.4. Luminous intensity distribution. The spatial distribution of the luminous flux

graphically depicted in a luminous intensity distribution curve, which is usually expressed in a polar diagram representing the light intensity as a function of angle about a light source. It is expressed in cd.

3.1.24.5 Photometric code. A six digit photometric code that displays the important ‘quality of light’ parameters; CRI, CCT, chromaticity co-ordinates and luminous flux.

Code X XX / X X X

Colour

Rendering Colour

Lumen Maintenance

Example:

Initial CRI value of 84 – code 8 Initial CCT value of 300K – code 30

Initial chromaticity co-ordinates within a 3-step MacAdam ellipse – code 3

Maintained chromaticity co-ordinates within a 5-step MacAdam ellipse – code 5

Maintained luminous flux of 91% - code 9

Photometric Code = 830/359

a. Correlated Colour Temperature (CCT).

In order to classify the different types of white light, the concept of colour temperature is applied

which is described as the colour impression of a perfect black-body radiator at certain



temperatures. The initial CCT value classification for the photometric code can be obtained by

taking the initial CCT value divided by 100.

b. Rated Colour Rendering Index (CRI).

Although light sources may have the same colour appearance, this doesn’t necessarily mean

that colour surfaces will look the same under them. The initial CRI value classification for the

photometric code can be obtained by using the following intervals:

Code

CRI Range

Colour rendering properties 6 57-66 Poor

7 67-76 Moderate

8 77-86 Good

9 87-100 Excellent

c. Rated chromaticity co-ordinate values both initial and maintained.

MacAdam ellipses are scaled up to a larger size of 3x, 5x or 7x the original. This is indicated

as a 3-step, 5-step or 7-step MacAdam ellipse. The initial and maintained chromaticity co-

ordinates are measured for the maintained value at 25% of rated life up to a maximum of 6000

hours. The classification for the photometric code can be obtained by using the following

intervals:

Size of MacAdam ellipse,

centered

on the rated colour target

Colour variation category

initial

maintained

3-step 3 3

5-step 5 5

7-step 7 7

˃7-step ellipse 7+ 7+

d. Lumen maintenance code.

The code number does not imply a prediction of achievable life time. The maintained luminous

flux is measured at 25% of rated life up to a maximum of 6000 hours and expressed as a

percentage of the initial values. The maintained value determines the lumen maintenance code.

Lumen maintenance (%) Code

˃90 9

˃80 8

˃70 7

3.1.24.6 Rated life (in h) of the LED module and the associated rated lumen maintenance (Lx).

The series of values for (x) is 70, 80 and 90.

3.1.24.7 Failure fraction (Fy), corresponding to the rated life of the LED module in the luminaire. The percentage (y) of a number of LED modules of the same type at their rated life that have

failed. This failure fraction expresses the combined effect of all components of a module including mechanical, as far as the light output is concerned. The series of values for (y) is 10 and 50.



3.1.24.8 Ambient temperature (ta) for a luminaire. The ambient temperature around the luminaire related to the specified performance. For a given

performance claim the ambient temperature (ta) is a fixed value. It is expressed in degrees Celsius.

3.1.24.9 Power Factor. The power factor shall be clearly stated in all cases.

3.1.24.10 Intensity Distribution.

Absolute Photometry shall be used. Relative Photometry shall not be accepted. Absolute

photometry of LED luminaires shall be conducted according to IES LM-79-08 Photometric

Measurements of Solid-State Lighting Products.

3.1.24.11 Drive Current. The power supply and electronics must provide a well-controlled DC drive current. Drive current is expressed in mA.

3.1.24.12 Optical Risk.

Optical risk identifies the risk group related to the exposure to hazardous sources of artificial

optical radiation. When light sources are placed in a luminaire, the Risk Group classification

can change due to the optics used in the luminaire. Risk Group 0 Exempt

Risk Group 1 Low

Risk Group 2 Moderate

Risk Group 3 High
