Energy performance of lighting systems

For a number of years, the attention has been drawn to the issue of energy saving not only in the field of lighting, but also in many other areas. A crucial moment in the process of dealing with this issue was the opening of the discussions on global warming. One of the effects of this discussion is that the pressure on a fast introduction of new technologies, procedures and new legislation, which would result in reducing energy performance of outdoor as well as indoor lighting systems, has been increasing. This paper deals with the relationship between the technical parameters of illumination and the energy performance of lighting and describes possible trends in achieving energy efficient lighting systems.
