Abstract

PURPOSE:To evaluate unpleasant glare quickly and readily, by obtaining a CIE GLARE INDEX by using equivalent light screen luminance at the position of the observer's eyes, which is obtained by using a glare lens, and a specified computing expression. CONSTITUTION:A glare lens 1 is provided at a position, where unpleasant glare is to be evaluated in an interior lighting facility. A measuring part 2 transduces the light through the lens 1 into an electric signal and measures an equivalent light screen luminance Leq. Then, in an operating part 3, a CGI (CIE GLARE INDEX) value is computed by using an expression CGI=1.20Leq.+9.8 based on the measured value, which is obtained in the measuring part 2. The CGI value, which is obtained in the operating part 3 is displayed on a display part 4. In this way, this device can contribute to the qualitative evaluation of a lighting visual environment in a general interior lighting field.
