Derived Illumination Specifications.
The article presents a study which evaluated the Weston-Crouch system of computing illumination intensities for a specified maximum visual performance percentage. H.C. Weston studied the effect of the size of work and brightness contrast to formulate a method to derive the illumination intensity nee...

L. ab: The article presents a study which evaluated the Weston-Crouch system of computing illumination intensities for a specified maximum visual performance percentage. H.C. Weston studied the effect of the size of work and brightness contrast to formulate a method to derive the illumination intensity needed for a given percentage of maximum visual efficiency. C. L. Crouch expanded Weston's technique by using more definite formulation and devising a monogram for the computation. In the study, the illumination intensities needed for fastest reading of newsprint and book print were compared with the corresponding intensities derived from the computations. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 1951 holdings: @attributes: islocal: N |
