Application of luminance contrast in the evaluation of industrial task lighting

A series of full-scale photometric simulation studies that were conducted to examine the luminous environment within workstations used in industrial applications are described. Industrial task lighting systems are studied in terms of their luminance and contrast distribution characteristics using a novel video-luminance scanning system which allows for the determination of all surface luminances within the work area. This information is used to develop optimum task lighting configurations for a range of representative industrial and assembly tasks. Experimental data show the importance of using luminance profile and contour data for the determination of contrast and glare within industrial lighting applications.<>
