Abstract
Practical lighting design has hitherto been seriously handicapped by the meagre amount of quantitative data on discomfort glare in most current lighting codes and handbooks. Much valuable fundamental information about glare is available, but before this knowledge can be transferred from the laboratory notebook to the lighting design handbook it must be converted into a form simple enough for the practising lighting engineer to use at the drawingboard stage of design, and it is with the solution of this and related problems that the present paper is primarily concerned. It is shown that by taking a realistic view of the accuracy required when specifying permissible luminance limits for general lighting luminaires, it is possible to devise a tabular method of specifying such limits which is exceedingly quick and simple to apply, yet subtle enough to take reasonable account of the known facts about glare. This new table of recommended luminance limits (for diffusing luminaires and bare fluorescent lamps used for evenly distributed general lighting in work places) has been incorporated in the new artificial lighting code (A.S. No. CA.30) recently published by the Standards Association of Australia.
