This article represents a continuation of a longstanding research concerning behaviour prediction (consumption) of lighting systems collected on the constant level of illuminance depending on daylight. Due to the occurrences of differences between the prediction model and the actual long-standing lighting measurement in monitored lighting system it has been vitally important to seek the source of...
To verify a quality of dimmed lighting systems with illuminance regulation to constant level it was necessary to develop an automatic measuring system. This system works as a long-term measurement of illuminance of interior workplace (10 illuminance at the same time) together with the daylight measurement. This system measures horizontal illuminance at the workplace as it is required by norms. However,...
The article describes verifying of behaviour of dimming in a regulated lighting system in Smart Home (SH) which was controlled to the constant level of illuminance. The proposed method of measuring was realized as an upgrade for evaluation of curves of interior illuminance caused by daylight. A reference room in SH with a measuring device evaluating illuminance in the places of visual tasks and at...
Today, except to boards that can be written with chalk or marker, used an interactive whiteboard. Interactive whiteboards are used in all types of schools, from elementary schools to universities. People perceive most of the information through the eye. The eye of is mainly perceived contrast. The aim of this study is to compare the photometric properties of interactive whiteboards and compare them...
