“…All of these significantly improved the experimental accuracy in the virtual environment [20,24,31,40]. Advanced lighting simulation with eye-tracking is of great importance for some special situations, such as traffic safety in driving and pedestrians [19,41,42,43]. The method's advantages could prove to be beneficial for visual perception and human factors research.…”

This paper investigated the effect of luminance contrast between sign and surrounding object on the gaze behavior of pedestrian, static or dynamic 360° panorama rendered in a virtual environment applied to simulate the wayfinding of pedestrians in the metro stations. Fifty-five participants observed the sign posters and the advertisement boards with distinct luminance contrasts (31 of them were in static levels, 24 of the rest were in dynamic levels) and were asked to point out the graphic or textual changes in the area after 30s. The eye tracker recorded ocular data, and glare perception was inquired by questionnaire. The result of T-test and Regression analysis revealed that luminance contrast was a saliency feature distinguishing visual targets and surrounding objects. The correlation between the value of luminance contrast and fixations, fixation durations on the sign is negative. Each increase in luminance contrast by one unit reduces the mean of fixations by 0.826, accompanied by a stronger feeling of glare, which indicated the strategic adaption of visual attention. The study contributed to our understanding of a new sight of lighting design in public traffic places and confirmed that lighting simulation in an immersive virtual environment can effectively analyzes visual perception.

“…Moreover, the issue of glare phenomenon occurred, which is related to the high luminance of single LEDs [8] and the way in which they were placed [9][10][11][12][13]. Another functional aspect was the quality of color rendering by the light-emitting diodes.…”

“…Another functional aspect was the quality of color rendering by the light-emitting diodes. It turned out that the current method of establishing color rendering (Ra) was insufficient in the case of LEDs [13]. Even though the document published by the International Commission on Illumination (CIE) in 1995 (CIE 13.3-1995) [14] states that the color quality can be evaluated using the CRI Ra method for all light sources, multiple researches have shown the problem with the precision of white light color rendering by LEDs [15][16][17].…”

Chip-On-Board Light-Emitting Diodes (COB LED) are increasingly more common. Their development in recent years has directly contributed to increasing the power of LED sources, whilst simultaneously increasing the luminous flux from the entire COB. Consequently, it has led to new developments in some applications. Information regarding the size of the light source luminous surface and luminance distribution on its surface is critical for a designer whilst designing optical systems. The purpose of this conducted research was to establish to what extent luminance distribution is even on the examined COB LEDs. In order to verify luminance distributions on an LED surface, direct measurements with a matrix luminance measuring device were made. As a result of the research, it has been observed that luminance distribution is not even, and in many cases luminance maximum does not fall in the geometric center of the luminous surface, which was initially expected. So, it has been concluded that while designing optical systems for COB LEDs, irregular luminance distribution on their surface needs to be considered.
