35 7 Requirements and test conditions for matrix light sources (MLS)
36 7.1 General requirements
37 Matrix light sources shall be so designed as to be and to remain in good working order when in normal
38 use. They shall, moreover, exhibit no fault in design or manufacture.
39 This clause 7 applies to matrix light sources with a Lambertian-like intensity distribution, i.e. I() ≈ I0 *
40 cos() (see clause 7.2.5.4).
41 NOTE: In the case of an MLS with an emission pattern that is not Lambertian-like, e.g. with primary
42 optics, some parts of this document may still be applicable, but special considerations and deviations
43 from the specified procedures may be necessary
44 Matrix light sources may consist of areas with different pitch values px and py, e.g. a central area with
45 a smaller pitch and outer areas with a larger pitch.
46 NOTE: In the case of an MLS with areas of different pitch values, it may be necessary to evaluate each
47 area separately, and some deviations from the specified procedures may be necessary

48 This clause 7 is intended to be applied to matrix light sources with a number of pixels in the order of
49 one hundred or less.
50 NOTE: In the case of an MLS with (much) more than 100 pixels, some parts of this document may still
51 be applicable, but certain deviations from the specified procedures may be necessary
52 7.2 Photometrical requirements and test conditions

87 Clause 7.2.5 covers parameters which are determined for each pixel individually.
88 Measurements of pixel parameters are made along the z-axis of the MLS.
89 The minimum distance between the grid and the aperture of the measurement equipment shall be 10 -
90 times the diagonal of the grid.
91 7.2.5.2 Partial luminous flux

101 7.2.5.3 Colour
102 The colour of each pixel is the colour of the light emitted by this single pixel into a cone of = 45°
103 around the z axis. The chromaticity coordinates shall comply with the limiting values given on the
104 relevant data sheet for the entire MLS.
105 7.2.5.4 Luminous intensity distribution

107 following directions:
108 - 0° (corresponding to the z-axis)
109 - ± 22,5° and ± 45° (in the x-z plane)
110 - ± 22,5° and ± 45° (in the y-z plane)

115 7.2.5.5 Luminance uniformity
116 The light emitting area (LEA) of a pixel is determined from luminance measurements of an area with
th
117 dimension px and py which contains the whole pixel. The value L is the 98 percentile of all values of
98
118 these luminance measurements.
119 The LEA of a pixel is the smallest circumferential rectangle having the same orientation as the grid and
120 containing all luminance measurements with a value of 20 percent or more of the value L .
98
121 In case the luminance does not drop below 20 percent of the value L98 in this area, the nominal pitch
122 size (px, py) shall determine the LEA of a pixel.
