Abstract

PURPOSE:To perform precisely and speedily the photometry with a simple constitution by selecting the detecting signals from the multiple light receivers with the multiplexer, inputting to AD coverter and adding by the adder the data of each light receiver. CONSTITUTION:Light receivers 2, for instance 30 pieces in number, are arranged around the lighting fixture to be measured 1, and their outputs are selected by the analog multiplexer 3 in turn, inputted by AD converter 4 and sent to the computing control circuit 5. This action is repeated 100 times, and 100 data are inputted at the interval of 1ms for each light receiver, then data for each receiver are added by the computing circuit. These data correspond with the integrated value during 100ms at almost same time. Because the integral circuit whose time constant is big is not used and the AD converter can do by one piece, high precision and high speed measuring can be made by comparatively simple constitution.
