Introduction to a study of preferred colour rendering of light sources

Abstract: The European Union has financed a 3-year research project to establish optimal spectral power distributions of LED light sources for use in offices, commerce and homes. This paper summarizes the general questions relevant to colour preference investigations and introduces the investigations performed in the three laboratories that participated in the research. Subsequent papers will deal with details of the investigations and provide recommendations for optimum spectra in different indoor applications.

“…The more realistic context and the more realistic environment may cause differences in the evaluations and judgments compared to those made when using viewing booths. 45 As found by Quartier et al, realistic light settings can have effects on perceived atmosphere and experienced emotions. 46 In this paper, we describe a psychophysical experiment to compare the colour preference of three LED sources for three different lighting applications: restaurant, retail display and supermarket.…”

“…4 Further studies are needed to validate other colour quality metrics in full-scale environments. Previous papers [5][6][7] have discussed the details of the investigations for office lighting. This paper describes the investigations that have been carried out in the full-scale laboratory rooms of the University of Pannonia.…”

“…First, test the hypotheses Table 5. Table 4 The values of the test statistics Di,j given by (4) The results of the experiments can be summarized as follows: The first object in the rank is the 3 rd one, but there is no significant difference between it and the following object in the rank, the 4 th one. They are followed by the 1 st and 2 nd objects.…”

“…Figure 1 shows the different cone sensitivities along the visible wavelength domain (380-780 nm). In order to evaluate the lighting quality of a light source under development, often, human visual experiments are used [4,5]. During the previous decade, this kind of visual experiments were carried out by using lighting booths with miniature models of real objects or small objects (e.g.…”
