Public outdoor (road) lighting consumes about 1.5 % of total electrical energy consumption [1]. Therefore, if the energy consumption for public lighting can be reduced by 30 % to 50 %, great energy savings can be achieved. With the use of LEDs and mo

When studying the process of photodegradation, we often deal with the durability of the individual ink colour components, the durability of the printing material or the durability of the ink on the printing material. Less frequently, ink degradation

Photodegradation of the ink-jet prints is a complex process in which many external and internal factors are involved. Nevertheless, the role of colorants and various accompanying substances in the ink is often overlooked. Our research work aimed to d

This paper presents a preliminary data analysis of vehicle speed on an urban road under different lighting levels. The speed limit on the road where the speed camera is located (near traffic lights and intersections, with speed bumps) is 50 km/h. The

The improper illumination of cultural heritage buildings and monuments can be a source of enormous light pollution, which can have a major impact on the overall environment of the illuminated area. Such lighting can be the result of carelessness or a

When measuring the lighting conditions in an indoor or outdoor environment (e.g. illuminance or luminance) one should always consider the conditions at which the photometer was calibrated and the used light source. In spite of ban of incandescent lam

The aim of the research was to find out how proposed new CIE standard illuminant L would influence the measurement uncertainty of photometrical field measurements of luminance and illuminance. With help of data of 10 different photometers and 75 spec

A method for a tuneable colour light source (TCLS) output spectrum synthesizing is described. A TCLS is a multichannel LED light source, which is able to mimic and produce different spectral distributions and can be used for the realization of differ
