The Calculation of Energy Saving in use Light Management Systems

Abstract

Light management systems are increasingly used in interior and exterior lighting. These systems offer many benefits for users of lighting. One of the most important advantages of these systems is the possibility of saving energy consumption for lighting purposes. Before deciding to use a lighting management system, it is worth knowing what value of savings energy this system will bring in specific case. The article present results of measurements basic light and electric parameters of LED luminaires with the possibility of controlling via DALI signal and obtained on base these measurements characteristic power control. Presented the method of calculating potential energy savings based on the received measurement results. Sources of differences between simulation calculations and real savings in using energy. The article present the differences between the evaluation of savings energy consumption simulation in the DIALUX program and real values. On the example of an existing lighting control system installed in sample room.
