Abstract
The paper presents two ways of using the solar radiation to limit consumption of the electric power for lighting, i.e., increasing the energy efficiency of lighting systems. The solar radiation energy is a generally available type of renewable energy that to a large extent may influence a reduction in consumption of the electric power for lighting. Facilities designers and architects aim at ensuring the highest possible availability of natural lighting in rooms. Usually, lighting systems are not provided with an appropriate control system using the solar radiation. A lack of means for a correct control of the artificial lighting intensity is a factor hindering an improvement of the energy efficiency of the lighting systems. Implementation of the correct control system is possible when distribution of the lighting intensity in a room is known. The studies conducted in this area are a valuable source of information which can be used to develop control algorithms or determine optimum locations and parameters for installation of lighting fixtures. The second way for improving the energy efficiency of the lighting systems is a use of the solar radiation energy converted to the electric power to supply lighting systems.
Highlights
The solar radiation reaching the Earth surface is composed mainly from the visible light and near-infrared wavelengths
Ways for using the solar radiation on a basis of results of tests and measurements proving that effectively used solar radiation resources can significantly influence an improvement in the energy efficiency of lighting systems are presented in further sections of this paper
The first method presented in the paper concerns the use of the daylight to light rooms, with simultaneous reduction in artificial lighting [6]
Summary
The solar radiation reaching the Earth surface is composed mainly from the visible light and near-infrared wavelengths. The amount of the solar radiation reaching a room depends on many factors. Possibilities for using the solar radiation energy are greater because photovoltaic systems are installed in optimal locations enabling maximum use of the available solar energy. This effective use of the solar radiation for lighting rooms and producing the electric power can significantly reduce consumption of the electric power used for lighting. The use of the solar radiation potential to the highest extent possible will depend on an appropriate selection of a system for control of the lighting system and installation of an efficient photovoltaic system. A reduction in an excessive solar radiation reaching a room can be controlled, for example, by using shutters or blinds
