Design of automated measuring system for goniophotometer

Abstract

This paper deals with the design of an automated measuring system for the goniophotometer. The goniophotometer is the device for the measurement of light distribution by changing the position of the luminaire. During measurement, the luminaire spins around the center of the luminaire in two axes, in the defined range. The purpose of the automated measuring system is to control two motors using CAN bus. To change the position of the luminaire, every motor has its own axis of motion around which it rotates. When the luminaire reaches a defined position, the proposed system measures the luminance intensity using a lux meter. Values of the luminance intensity are saved in the file in EULUMDAT format. The proposed system was created in the graphical programing language LabVIEW.
