Due to their potential use as an internal reference, memory colours have proven to provide an excellent conceptional approach for the colour rendition evaluation of white light sources in terms of predicting visual appreciation. However, there are still some major drawbacks that can be identified in the principal design of existing memory-based or memory-related colour quality metrics. For this reason, a new experiment was devised trying to overcome the shortcomings of these previous approaches. Based on the experimental output, the main goal of the current study consequently was to derive an improved version of a memory-based colour quality metric, which provides a superior tool for developers and manufacturers that can be used for the optimization of state-of-the-art lighting solutions in cases where visual appreciation and high user acceptability are more important than colour fidelity.

The calculation of field-of-view luminance based metrics for visual discomfort from glare evaluation in real scenes via HDR (High Dynamic Range) luminance capture does generally require the use of wide view fisheye lenses. This paper presents an easy to implement and low-cost method to estimate a fisheye lens’ total field-of view and projection method, which is required for accurate glare evaluations.

Article is focused on describing philosophy andpotentialof public lighting network on testing polygon University of Báňská. The main idea is using continuous 24h electric power (at this time public lighting use average 12h of lighting) for extension functionality of public lighting network using idea of “smart city”. The project on which the article is based is focused on testing of light and technical parameters and on implementation of “smart devices” within renewal of the existing city lighting system.
