Abstract

PURPOSE:To evaluate the degree of unpleasant glare quickly and readily, by using equivalent light screen luminance at a position of the observer's eyes, which is obtained by using a glare lens, and a specified computing expression, and obtaining the unpleasant glare. CONSTITUTION:A glare lens 1 is provided at a position, where unpleasant glare is evaluated in an interior lighting facility. A measuring part 2 transduces the light through the lens 1 into an electric signal and measures equivalent light screen luminance Leq. In an operating part 3, a degree G of unpleasant glare is computed by using an expression G=0.20Leq.-0.64 based on the measured value, which is obtained in the measuring part 2. The evaluated value of the unpleasant glare, which is obtained in the operating part 3, is displayed on a display part 4. For example, G=1 denotes 'can be felt', G=3 denotes 'preoccupied', G=5 denotes 'unpleasant', and the like.
