Methods to Improve Quantitative and Qualitative Indicators of Lighting in Classrooms

Abstract

In order to save electrical energy, in the last ten years, LED lighting fixtures have replaced the fluorescent lighting fixtures used for indoor lighting, especially those in educational and administrative buildings. The LED illuminators have the same overall dimensions and luminous flux as the replaced ones, but with significantly less consumed power. Often, reducing lighting costs leads to neglecting some of the others qualitative and quantitative indicators of light sources, such as color rendering, light distribution curve, pulsations, etc. In this report, the possibilities for the reconstruction of existing lighting arrangements will be considered, and quantitative and qualitative indicators in these laboratories will be measured.
