Stadium lighting projects with parametric simulations and application examples

This work of stadium lighting design, is not a copying of design applications in the existing stadiums, but it introduces a new method as result of a different working. In this method, imaginary triangles between floodlights, focus points and ligting level calculation points are taken into consideration. In this work, the required calculations are realized by developing a matlab programme. By varying many different parameters in the matlab programme, the effects to lighting levels were investigated. Lighting levels are separately calculated as both horizontal and vertical. Instead of horizontal lighting approach that had been done in the past, an appropriate principle for high definition HDTV broadcasting is adopted. In this work, from the obtained values for four poles lighting, it was seen that the obtained vertical and horizontal lighting levels and cosequently lighting productivity are increased as floodlights approach to field. On the other hand, as inversely proportional with this increasing, deterioration of lighting level dispersion is observed. At the same time, passing over acceptable limits of brightness values are understood as floodlights approach to field. Since the correct perception of colours is essential both for players to be seen in true colours and for color television broadcasting, high color rendering lamps are choosen.. Therefore, in the stadium lightings, particularly for international games, metal halide floodlights discharge lamps possesing high color temperature and color rendering and suitable for high definition HDTV broadcasting must be used
