Paper Abstract

In practice, the problem of vision discomfort appears at a number of different work-stands. Among others, it concerns people like drivers or people working with screen monitors. As a result of extensive research into appropriate illumination, a number of recommendations have been produced in order to ensure comfort of vision at work-stands. It is assumed that if the work-stand is provided with sufficiently high level of illuminance, and if the luminance distribution is uniform, and there is no glare, then we have comfort of vision and the eye fatigue is acceptable. Currently, to measure luminance distribution in order to assess the quality of illumination, it is necessary to carry out a large number of point measurements by using the luminance meter. Another way of determining the luminance distribution coming from the sources lying in a relatively small solid angle is the application of luminance meter built by using a CCD camera. Measurements of this type require, however, a great number of exposures to determine luminance distribution coming from light sources located in a large solid angle (e.g. a halfspace). This paper presents a design model of luminance distribution meter which makes it possible to obtain data about the distribution of luminance coming from light sources located in the whole halfspace only by a single measurement. Furthermore, the meter enables simultaneous determination of all the parameters on the work-stand illumination quality.
