Paper Abstract

During the designing process for a luminaire with the light guiding plate, first it is necessary to analyze the issue of coupling light source with the light guiding plate, since only the luminous flux which is introduced into the light guiding plate might be utilized further on and become the useful flux. Theoretical calculations of the coupling index between the fluorescent lamp and the light guiding plate were made. The measurement's results confirmed the conclusions from theoretical calculations, namely that the best possible solution is placing the fluorescent lamp directly at the surface of the light guiding plate. Placing the lamp 2 millimeters from the plate's front surface causes the decrease by 20%, and further increase in the distance to 5 millimeters -- decrease by 50%.
