PREDETERMINATION OF LUMINANCE IN STREET LIGHTING. PRESENTATION OF DATA AND CONTROL OF RESULTS

FOR THE ROAD USER THE MAIN QUALITY CRITERIA OF A LIGHTING SYSTEM ARE THE LEVEL AND EVENNESS OF ITS LUMINANCE. THE LUMINANCE DEPENDS ON THE OPTICAL CHARACTERISTICS OF THE SURFACING, CHARACTERISTICS WHICH MUST BE FORESEEN, IMPROVED AND CONTROLLED. THIS ARTICLE (1) GIVES THE METHOD TO FOLLOW FOR THE CALCULATION AND PRESENTATION OF LUMINANCES (LUMINANCE CANVAS), (2) REDEFINES A NEW METHOD OF PRESENTING LIGHTING VALUES WHICH CAN BE THE SUBJECT OF ACCEPTANCE CONTROL.
