“…These measurements include luminous flux measurements, illuminance measurements, luminous intensity measurements and luminance measurements. Luminous flux measurements are the most common photometric measurements [1][2][3][4][5][6]. They make it possible to determine how much light is emitted from a light source or a luminaire.…”

“…The method using the measurement of luminous flux is another indirect photometric for determining the average luminance seen from a given direction. With some simplification and assuming a uniform luminance distribution over the surface area of the light source, the so-called dimension luminance can be determined from the known relation (5) [25]. With the dimension luminance defined in this way, it is assumed that the total luminous flux radiated from the light source comes from the surface area of the Luminance Intensity Distribution described in this source.…”

Luminance measurements are the least frequent of all photometric measurements. This article characterizes and systematizes the various methods of luminance measurement. In particular, the method of direct luminance measurement using modern luminance meters (ILMD) is described in detail. This paper presents the results of the study on the influence of the measurement distance on the luminance measurement results. Two ILMD meters (laboratory and portable) and a luminance standard were used in this study. The conducted research showed that an incorrectly chosen measuring distance can lead to significant measurement errors of up to several tens of percent. In addition, the possible impact of incorrect measurements on the design of an interior lighting installation was presented. It was shown that the selected interior lighting installation can consume more than 40 percent more electricity compared to the installation based on the correct luminance measurements of the luminaires with diffuse shades. In the final stage of the study, the definition of the photometric test distance for luminance measurements using ILMD was proposed. The test results can be particularly useful for the luminance measurements of OLEDs or the luminaires with diffuse luminous character. However, these results can also be used for luminance measurements of other light sources and luminaires.

“…For this reason, in many applications, fluorescent lamps are replaced by LED sources, which luminous efficiency improves as the ambient temperature decreases [9]. The manufacturers of light sources provide photometric and colorimetric parameters for an ambient temperature equal to 25 o C [10,11]. However, when LED sources are used in outdoor lighting, the operating conditions differ from those corresponding with this temperature.…”

The paper presents the results of calculations of colorimetric parameters of LED sources operating at a temperature range from -25oC to 25oC. The chromaticity coordinates and color rendition quality parameters were calculated on the basis of registered spectral distributions of radiation. For individual LED chromaticity shift is illustrated at CIE 1931 x,y diagram with 3 step and 7 step MacAdam ellipses. Full Text: PDF ReferencesJ. P. Freyssinier, D. Frering, J. Taylor, N.
